Bu çalışma, moringa tohum çimlenmesi ve fidan gelişimi olmak üzere iki aşamadan oluşmaktadır. Öncelikle moringa tohumlarına kontrol dışında, dört farklı uygulama (a: 35°C’deki ılık suda 24 saat bekletme; b: 1000 ppm GA3 çözeltisinde 24 saat bekletme; c: -1MPa polietilen glikol (PEG) çözeltisinde 24 saat bekletme; d: 2500 ppm mikrobiyal gübre çözeltisinde 24 saat bekletme) yapılmıştır. Kontrollü koşullarda gerçekleştirilen çimlendirme denemelerinde sıcaklık, 25°C ve oransal nemi ise %80’in üzerinde olacak şekilde ayarlanmıştır. Tohum ekiminden sonra, çimlenme oranı, süresi ve çimlenme enerjisi her bir uygulama için belirlenmiştir. Çimlenmeden sonra fidanlar 1:1 oranında torf ve perlit içeren yetiştirme ortamına aktarılmıştır. Daha sonra fidanlara 15 gün ara ile altı defa NPK, NPK + 2500 ppm mikrobiyal gübre ve NPK + 5000 ppm mikrobiyal gübre uygulamaları yapılmıştır. Yetişen bitkilerde 90 gün sonra, bitki boyu, gövde çapı, klorofil miktarı, gövde, kök yaş ve kuru ağırlıkları belirlenmiştir. Araştırma bulguları, tohum çimlenme oranı, süresi ve enerjisi açısından en iyi sonucun, tohumların viyollere ekimden önce 35°C’deki ılık suda 24 saat bekletme uygulamasının verdiğini göstermiş ve bu uygulamayı 1000 ppm GA3 çözeltisinde 24 saat bekletme uygulaması izlemiştir. Fidan büyüme ve gelişmesi açısından incelenen parametreler göz önüne alındığında, standart NPK’nın mikrobiyal gübre ile birlikte kullanımı, standart NPK’ya göre daha iyi sonuç vermiştir. Araştırma sonucunda, tohum çimlenmesi açısından 35 oC’deki ılık suda 24 saat bekletme ve fidan gelişimi açısında ise standart NPK’nın mikrobiyal gübre ile birlikte kullanımı tavsiye edilmiştir.

The consumption of grass juices obtained from cereals for health purposes is increasing day by day. For this purpose, research on different plant solutions has gained momentum. In our study, barley (Hordeum vulgare L.) and oat (Avena sativa L.) grass juices grown in hydroponic conditions were used. Obtained grass juices were applied to pea and lupine seeds in 100% soil (control), 100% pumice, 100% perlite, 100% tea waste and 100% cocopeat substrate. Germination percentage, germination rate, average daily germination, peak value, germination value, root dry and fresh weight, stem dry and fresh weight, root and stem length, plant yield, grass yield, plant yield seed rate, macro and micro (N, P, K, Ca, Mg, Fe, Cu, Zn and Mn) mineral substance contents were investigated pea and lupine. Grass juices were obtained by mowing barley and oat seeds sown in 30 x 50 x 7 cm plastic tubs in ten days and passing them through a juicer. Pea and lupine 25 seeds, which were placed in each pot, were grown in different root media (100% soil, 100% cocopeat, 100% pumice, 100% perlite, and 100% tea waste) under in vitro conditions. 150 ml of water (control), barley grass juice, oat grass juice and barley + oat grass juice were applied to the seeds according to their subjects. The experiment was carried out in 400 pots with 10 replications x 2 species x 4 treatments x 5 media, according to the factorial fully randomised design. As a result of the research, germination physiology (germination percentage, germination rate, average daily germination, peak value and germination value), mineral substance content (N, P, K, Ca, Mg, Fe, Cu, Zn and Mn), growth and yield parameters at (root dry and wet weight, stem dry and wet weight, root and stem length, plant yield, grass yield, plant yield seed rate) barley grass juice application was found to be more effective than other applications after control. In all parameters examined in the research, it was determined that the five different medias used as growing media followed the order of soil>cocopeat>pumice>perlite>tea waste, and after the control and the best growing medium was cocopeat.

Weed seed banks are latent biotic stress contributors to low crop production among smallholder farms. The objective of this study was to investigate effect of repeated soil nutrient amendments on weed seed bank dynamics in eastern Zimbabwe. Soil samples were taken from three farms with low, medium and high soil organic carbon (SOC) along the catena. Sampled treatments included varying combinations of compound D (7%N, 14%P, 7% K) fertiliser, cattle manure and lime. Weeds that emerged per plot were counted by species and data was tested for normality before running a linear mixed-effects model and Restricted Maximum Likelihood. Principal Component Analysis (PCA) was performed to establish the relationship between seasons, SOC, soil nutrient amendment, and emerged weeds. Significant (p < .05) species richness (Margalef index), and Shannon Weiner index were recorded in the medium (6.4g kg-1soil), high (8 g kg-1 soil) and low (< 3.9 g kg-1soil) SOC. Weed species emergence was significantly (p < .05) influenced by the level of SOC along the catena positions, representing results from the source. Emergency and abundance of weeds such as Richardia scabra, was associated with low SOC acidic sandy soils from the upper catena. However, application of nutrients (NPK+lime treatment) reduced weed species counts from 1.96±0.12 to 1.4±0.12. Cattle manure and NPK+CM treatments recorded significantly higher weed emergence, and weed biomass; compared to the control. Clearly, cattle manure treatments significantly increase the soil weed seed bank; thus, weeding intensity is likely to increase in cattle manure treated fields.

In nature, plants constantly fight against the negative effects of biotic and abiotic stress factors. Salinity encountered in agricultural areas in the world and in our country is one of the most important factors that negatively affects sustainable agriculture. This study was carried out to investigate the effects of Gibberellic Acid (GA3) and Glycine Betaine (GB) applied as pre-treatment to sunflower seeds under salt stress conditions on germination and seedling development. In the experiment, the seeds were pre-treated with four different concentrations of GA3 and GB (0, 15, 30, 45 mg/l) before planting, and then four different salt (Na+Cl-) concentrations (0, 6, 9, 12 dS/m) was put into salt stress application. The experiment was set up with 3 replications according to the Randomized Plot Factorial Trial Design. In the study, germination rate, germination power, seedling length, root length, seedling fresh weight, root fresh weight characteristics and enzyme activities such as CAT, SOD and POD were examined. In the experiment, parallel to the increase in salinity stress, decreases in germination rate and germination power and negative effects on other seedling characteristics were observed. According to the results obtained, positive results were observed for germination and seedling characteristics at 6 dS/m salt stress in 30 and 45 mg/l GB and GA3 applications. As a result, it was concluded that Glycine Betaine applications to sunflower seeds as an alternative to plant regulator groups under salt stress conditions will be beneficial in production.

In this study, seeds of cotton plants were coated with different boron concentrations and their effect on seedling growth was investigated. The experiment was carried out at Muş Alparslan University, Faculty of Applied Sciences, Department of Plant Production and Technologies, under laboratory and greenhouse conditions, according to the Randomized Plots Trial Design with 4 in laboratory and 3 in greenhouse replications, respectively. In the study, Di-sodium tetraborate decahydrate (Na2B4O7.10H20) (M=381.37 g mol-1) with a minimum purity of 99% boron compound have been used in different doses; 0 (control), 250, 500, 750, 1000, 1250, 1500, 1750, 2000, 2250 and 2500 mg kg-1. According to the results of the regression analysis, it was determined that as the boron dose in the application increased, the root length was positively correlated and other parameters were negatively correlated. In terms of the parameters examined, 250 mg kg-1 Kaolin+liquid K-Humate (15% HA) 400 ml kg-1 (U3) boron application under laboratory conditions showed better results, and 1000 ml kg-1 Kaolin+liquid boron application under greenhouse conditions. It was determined that the application of K-Humate (15% HA) 400 ml kg-1 (U6) promoted growth. In addition, it was found that the results were confirmed in the grouping of the relationships between applications and parameters with heat map clustering and PCA graphs. As a result, it was determined that the toxic range of boron applications applied to the seed in the cotton plant was very narrow, and that it promoted seedling development and root elongation in the U6 application, but it was concluded that the study should also be studied in field trials in order to make more decisive decisions.

In tropical and semi-tropical climates, the preservation of oilseeds is important for the preservation of germination ability and quality. When the oilseeds are not kept under proper storage conditions immediately after harvest, they immediately begin to deteriorate and lose their quality. This study was conducted in Adana province conditions with a semi-tropical climate type to determine the effects of different storage conditions on soybean seed quality. Trials, storage and laboratory studies were organized and analyzed in factorial coincidence parcels with 2 years and 3 repetitions according to the factorial trial pattern of 25. In the study, factors such as storage time (7 and 9 months), storage condition (traditional warehouse, cold storage warehouse), packaging material (PE sack, vacuum bag) and different large soybean variety (Yeşilsoy, Nazlican) have been determined to affect oil, protein and germination ability on soy seed stocks. At the end of the study, it was determined that the storage time and the variety had a statistically significant level of p = 0.01 on fat, protein and germination rates. At the same time, it was determined that the storage condition p = 0.01 and the package material p = 0.05 were effective on germination, but these two factors had no statistical effect on fat and protein. When the data were evaluated, it was determined that the worst results were obtained from storage with "Traditional warehouse + PE sack" for both varieties in soy storage. In this storage, the very high germination rates of the Yeşilsoy (93.5%) and Nazlican (93%) varieties at the beginning of storage decreased by 56% and 45.83% respectively after 7 months of storage. At the end of 9 months of storage, it was determined that it decreased by 50.33% and 42.67%, respectively. As a result, in the storage of soy; it is determined that the ability to germinate is more protected than other issues provided that small seed soy varieties are preferred, stored in cold storage warehouse and storage time is not more than 7 months. In addition, when the cost as package material is taken into consideration in cold storage warehouse conditions, it is believed that PE material can be used instead of vacuum bag. It is thought that the storage conditions change according to the type and varieties of oilseed and these conditions should be determined by taking into account the environmental conditions according to the varieties.

Lotus corniculatus L. is one of the agronomically and economically important perennial legume forage species with moderately salt-tolerant. It is well known that even the cultivars of the same species in plants have different responses in salinity. However, studies on the salt response of L. corniculatus and its cultivars, which are more advantageous than other forage crops such as white clover (Trifolium repens) and alfalfa (Medicago sativa L.), in the use of marginal agricultural lands affected by abiotic stress factors such as salinity, are limited. Under salt stress, the most crucial phases of the plant life cycle that are directly related to the survival of the plant are seed germination, growth, and vigour. Therefore, this study was carried out to determine the germination and growth responses of L. corniculatus cultivar 'Leo', which is known to have higher tannin content than other cultivars, under NaCl-derived salt stress in vitro. For this purpose, L. corniculatus seeds were cultured in MS (Murashige and Skoog/Gamborg) medium containing 0, 40, and 80 mM NaCl for 14 days. Seed germination percentage, mean germination time, germination rate index, shoot-root length, root to shoot length ratio, shoot-root fresh dry weight, shoot-root dry matter, the ratio of root to shoot dry matter, shoot-root water content and seedling vigour index parameters were measured. According to the results of the research, the germination percentage did not change in the applied NaCl treatments, but the germination rate decreased. However, shoot length decreased and root length increased. Although there was no statistically significant change in shoot and root fresh-dry weight, both decreased in 80 mM NaCl treatment. The shoot and root dry matter increased and the water content decreased. Also, the seedling viability index decreased. In 40 mM NaCl treatment, on the other hand, there was an increase in shoot fresh-dry weight, dry matter ratio and seedling viability index with the positive effect of low dose. Within the scope of this study, comprehensive information was presented for L. corniculatus (cultivar 'Leo'), an important forage plant, in terms of germination and seedling growth under salt stress.

Drought is an important abiotic stress factor that reduces agricultural production and yield in many crops, including forage crops, in agricultural areas around the world. Lotus corniculatus L. is the agriculturally crucial perennial legume forage crop that can tolerate moderate drought. However, studies to determine the responses of L. corniculatus to drought are limited. Therefore, this study was carried out to determine the seed germination and early seedling growth properties of L. corniculatus at different PEG6000 induced-drought treatments under in vitro conditions. In order to do this, L. corniculatus (cv. ‘AC Langille’) seeds were planted in MS (Murashige and Skoog/Gamborg) medium containing 0%, 4%, and 8% (w/v) PEG6000 for 14 days. In this study, germination percentage, mean germination time, germination rate index (speed of germination), shoot and root length, root to shoot length ratio, shoot and root fresh weight, shoot and root dry weight, shoot and root dry matter ratio, root shoot dry matter ratio, shoot and root water content and seedling vigor index parameters were measured. Our results showed that increasing drought levels resulted in an overall significant reduction in germination and seedling growth parameters except shortened mean germination time (especially, 4% PEG6000 treatment) and increased shoot and root dry matter ratio at higher (especially, 8% PEG6000 treatment) drought levels. When important growth parameters such as length, fresh and dry weight, dry matter ratio and water content, which show the development of root and shoot organs, are evaluated together, it has been determined that the root is negatively affected by drought stress at a higher rate. Based on these data, it can be concluded that the L. corniculatus will suffer a high yield loss under the drought stress at the osmotic potential (-1.03 bar) created by 8% PEG6000 treatment.

When it comes to the development of plants, the first step is the healthy germination of the plant seed. The realization of this situation can be more difficult when it comes to orchids compared to other plant species. In this study, in-vitro germination of orchid seeds was observed. Abiotic factors such as temperature, drought and Ph can create stress against seed germination and have an inhibitory effect on seed germination. In order to prevent this situation, the seeds are covered with biological agents by some methods. In this study, by using endophytic bacteria and fungal isolates isolated in our previous studies, the seeds were covered with biopriming applications in the laboratory and it was observed whether there was a positive effect on the germination of orchid seeds. In the evaluation, it was observed that the mixtures containing both endophytic fungal and bacterial samples were the most effective treatments. This study constitutes the first example of both fungal and bacterial probiotic testing in orchids. [ABSTRACT FROM AUTHOR]

Bu çalışmada, test materyali olarak Allium cepa L. kullanılarak çeşitli fizyolojik, sitogenetik, anatomik ve biyokimyasal parametreler üzerine dışsal 4-metil umbelliferonun (4-MU) doza bağlı etkileri araştırıldı. İncelenen fizyolojik parametreler: çimlenme yüzdesi, kök uzunluğu, kökçük sayısı ve taze ağırlık; sitogenetik parametreler: mikronükleus (MN) sıklığı, kromozom anormalliği (KA) ve mitotik indeks (Mİ); biyokimyasal parametreler: serbest prolin içeriği, malondialdehit (MDA) düzeyi, katalaz (KAT) ve süperoksit dismutaz (SOD) aktiviteleridir. Soğan kök ucu hücrelerinde meydana gelen yapısal değişimler anatomik kesitler alınarak incelendi. Bu amaçlar için, soğanlar bir kontrol ve üç uygulama olmak üzere dört gruba ayrıldı. 7 gün süresince kontrol grubundaki soğanlar distile su ile muamele edilirken; uygulama gruplarındaki soğanlar 4-MU’nun 125 µM, 250 µM ve 500 µM dozları ile muamele edildi. 4-MU uygulaması kontrol grubuyla kıyaslandığında fizyolojik parametrelerde bir azalmaya neden oldu. Bu uygulama, KA ve MN sıklığında bir artış ile Mİ'de bir azalma meydana getirdi. Ayrıca, 4-MU muamelesi kontrol grubuyla karşılaştırıldığında KAT ve SOD aktiviteleri ile MDA ve serbest prolin içeriklerinde de doza bağlı olarak bir artışa neden oldu. Ayrıca, tüm 4-MU uygulamaları sonrasında, epidermis hücrelerinde MN oluşumu, epidermis ile korteks hücre deformasyonları, kortekste bazı kimyasal bileşiklerin birikmesi, belirgin olmayan iletim dokusu ve nekroz gibi kök anatomik değişimleri tespit edildi ve bu anatomik değişimlerin 500 µM 4-MU'da maksimum seviyelere ulaştığı bulundu. Sonuç olarak, 4-MU incelenen tüm parametreler üzerinde olumsuz bir etki gösterdi ve bu etkilerin izlenmesi için Allium test materyalinin yararlı bir biyoindikatör olabileceği tespit edildi.

Indonesia has a wide range of swampy lands that need to be recovered for safe agriculture. The swampy lands and vegetation are a source of soil contamination through root exudates that need serious improvement. The plant exudates in soil could disturb seed germination. This study aimed to determine the effect of ethanol vapor treatment on the decrease in the vigor of four soybean seed cultivars. This study used a randomized block design with two treatment factors, namely ethanol-based ageing treatments as the main factor and cultivars as subfactor. The observation variables consisted of the percentage of germination, growth rate, vigor index, sprout length and sprout dry weight. The results showed that there was an interaction effect between fast ageing time and ethanol treatments and soybean cultivars which caused a decrease in the seed vigor. The soybean seeds of the cv. Gema was able to maintain more vigor compared to the cv. Grobogan which experienced more decline in germination. The 5 minutes of ageing time induced fewer damages with the highest vigor while 20 minutes of ageing the seeds induced maximum damage with the lowest seed vigor. [ABSTRACT FROM AUTHOR]

Entomopathogenic fungi, a promising alternative to conventional insecticides, have been widely used as biocontrol agents for the regulation of pest populations. Furthermore, recent studies have shown that entomopathogenic fungi also have growth-promoting properties in plants. The purpose of this investigation was to assess the effects of indigenous entomopathogenic fungi strains, Beauveria bassiana Pa4, Cordyceps fumosorosea KTU-42, and Metarhizium flavoviride As-18, on the germination and early development period of sunflower and maize plants. In this study, it was determined that EPF application did not affect the seed germination percentage in maize, but increased the germination percentage of sunflower seeds. It was determined that M. flavoviride application significantly increased root-stem weight, root length, stem diameter and biomass in sunflower samples compared to other EPF applications and control. In maize, it was determined that EPF applications had a positive effect only on root length. The most effective fungus to increase growth on maize plants was C. fumosorosea KTU-42. On the other hand, the same result was obtained with M. flavoviride As-18 on sunflower plants. The present study reported that these fungi promote plant development and should be considered an important factor in plant production besides pest management.

The present study was carried out using Dinçer and Olas safflower varieties at 5 different salt (NaCl) concentrations (0, 50, 100, 150, and 200 mM) for 14 days. The germination percentages of the cultivars under salt conditions as well as the activities of antioxidant enzymes (SOD, CAT, POD and APX) and biochemical changes (protein and MDA) in the seedlings were determined. The germination percentage decreased with increased salt concentrations, and the greatest decrease in germination percentage was observed at a 200 mM salt concentration by 34% in both cultivars. The activity of superoxide dismutase (SOD) increased at low salt concentrations, but decreased after 100 and 150 mM salt concentrations, respectively. Catalase (CAT) and ascorbate peroxidase (APX) activities, as well as malondialdehyde (MDA) and hydrogen peroxide (H2O2) contents, increased with increasing salt concentrations at Dinçer and Olas, but total soluble protein content decreased with increasing salt concentration. Peroxidase (POD) activity was not significantly affected by salt stress in safflower. Germination percentage showed negative correlations with CAT, MDA and H2O2 levels, and showed a positive correlation with soluble protein content under salt stress in safflower. The present results may be useful to identify mechanisms of salt tolerance involving antioxidant enzyme activities and biochemical changes in safflower seedlings.

Dill, Anethum graveolens L., is grown in various regions of the world. It has been used as vegetable and medicinal plant since ancient times. Seed quality is important in dill cultivation and there is limited information on the effects of cutting treatment in this species. This research was carried out to find out the effect of cutting treatment on phenological traits, seed yield and quality of dill at Ege University, Izmir, during 2016-2018. The experiments were carried out in the randomized complete block design with three replications, comprising of cutting treatment for both spring and autumn seeding period. Significant differences were noted in the flowering period, seed yield and quality attributes with cutting treatment for both seeding period. The obtained results showed that the days from sowing to bolting initiation were increased with cutting treatment from 51 days to 65 days in spring seeding period and from 153 days to 184 days in autumn seeding period. The plant height, number of umbels per plant, seed weight per plant were lower in the cut plants in comparison to that of uncut plants for both seeding period. The uncut plants has produced significantly higher plant height (113 cm-spring seeding period; 133 cm-autumn seeding period), number of umbels/plant (8.4-spring seeding period; 10.1-autumn seeding period) and seed weight/plant (6.4 g-spring seeding period; 10.9 g-autumn seeding period). The cutting treatment decreased germination percentage by 9.27% in the spring seeding period and by 12.13% in the autumn seeding period compared to the control plant seeds. Lower mean germination time at 20/30°C (3.77 days-spring seeding period; 4.54 days-autumn seeding period) were also observed in uncut plants. Thus, it was concluded that cutting is not recommended in the vegetative stage in dill seed production as it provided lower seed yield and seed quality for both autumn and spring seed planting periods.

White mustard (Sinapis alba L.) is one of the two important species in Turkey in the Sinapis genus belonging to the Brassicaceae family. It is a weed found in agricultural areas in weed surveys conducted in our country in recent years. This study was carried out with the seeds of White mustard (S. alba L.) randomly collected from the fields of Manisa province in 2019, and the minimum, optimum and maximum germination temperatures of the seeds of this weed species were determined. The experiment was carried out in Malatya Turgut Özal University, Faculty of Agriculture, Department of Plant Protection, Herbology laboratory in 2022. In laboratory studies, temperatures of 2, 5. 10, 15, 20, 25, 30, 35 and 40 °C were used to determine the appropriate germination temperatures of White mustard seeds. Experiments were set up with 4 replications and repeated 2 times. As a result of the study, it was determined that the minimum, optimum and maximum germination temperatures of White mustard seeds were 5 °C, 20-25 °C and 35 °C, respectively. Since the results were parallel to each other, the average of the two trials was taken into consideration. As a result, due to global warming, White mustard weed species cause problems in cultivated plants and can increase population density in important cultivated plants if they are not controlled. Seed biology is important in the control of the White mustard species, and the findings revealed the germination abilities of the White mustard species at appropriate temperatures. In addition, it is thought that this study will shed light on other studies to be done with White mustard in the coming years. [ABSTRACT FROM AUTHOR]

This study was conducted in laboratory conditions to determine the response of some cool season turf grass species (Lolium perenne Caddieshack, Lolium multiflorum Jivet, Poa pratensis Evora, Festuca rubra Rassinante, Festuca arundinacea Starlet, Festuca ovina Ridu) to different salt doses during the germination period. In the study, 8 different NaCl doses, 0, 30, 60, 90, 120, 150, 180, 210 mM, were applied, germination rate (%), germination time (%), plumula length (cm), radicula length (cm) and vigor index values were examined. Because of the research, it was observed that the germination rate, plumula and radicula lengths increased at 30 mM concentrations and in general, significant damage occurred after the dose of 90 mM. Lolium perenne Caddieshack and Lolium multiflorum Jivet species showed the highest mean values and were less affected by increasing salt doses in all properties examined. [ABSTRACT FROM AUTHOR]

In this study, it was aimed to investigate the impact of water stress on germination and determine drought tolerant provenances in different Anatolian Black Pine provenances. Levels of water stress between 0 and -0.8 MPa were applied by using solution of PEG-6000 and germination tests were carried out. Our results revealed that germination values significantly decreased with increasing water stress level among provenances. Accordingly, Nallıhan, K. Hamam, Çerkeş and M.K. Paşa provenances, which represent regions with lower rainfall, had higher germination values up to -0.6 and -0.8 MPa water stress levels compared to other provenances. In this respect, mentioned provenances were found to be more resistant to drought. This result shows that there are variations within species in Anatolian Black Pine in terms of drought tolerances. Using provenances, which are determined to be drought-tolerant in this study, can increase afforestation success in semi-arid regions.

With climate change, global warming has increased adverse effects on living things in our country. In these adverse effects, water scarcity is the most crucial problem due to the increase in temperature and decrease in precipitation. Forests are the most affected ecosystem among others by water scarcity in our country. This study tried to determine the 5-year-old seeds and 1-year-old seedlings (produced from the same seeds) of some Turkish red pine provenance’ responses to different water stress levels. First, how the water stress levels (0, -0.2, -0.4, -0.6, -0.8 MPa) affect seed germination of these provenances was determined. Secondly, gas exchange parameters [net photosynthesis (Anet), stomatal conductance (gs), transpiration (E), and intrinsic water use efficiency (iWUE)] under different water stress were determined in the seedlings obtained from these species' seeds. As a result of the germination test, Denizli-Çameli (DC) provenance had the highest rate (48%), while Maraş-Suçatı had the lowest rate (29%) under control treatment. The highest germination rate was obtained in Burdur/Bucak provenance (5%) under -0.2 MPa osmotic potential. For gas exchange parameters, Antalya/Gündoğmuş provenance had the highest Anet, gs values while DC provenance had the lowest Anet, gs, and E values when provenance is considered as a single factor. Besides, increasing in irrigation increased Anet, gs, and E while decreased the iWUE. The lowest seedling E under water stress can be explained because this species responds to the water shortage by closing its stomata. Among the Turkish red pine origins, DC provenance showed higher drought tolerance than others.

The non-essential heavy metal cadmium (Cd) prevents rice seed germination and seedling growth when it is present in micromolar concentrations. To mitigate the effects of Cd toxicity on rice, seed priming, a pre-germinated seedling approach, may improve seed and seedling performance. In 2019, an experiment was conducted in Turkey to evaluate seed germination and seedling growth of rice. The experiment was comprised of five concentrations of Cd stress (0, 50, 100, 200 and 400 ppm) on three rice cultivars (Osmancık 97, Halilbey, and Kızıltan) and three seed priming techniques such as hydropriming, priming using 2% KNO3 (potassium nitrate), and priming using 100 mg/L salicylic acid. The complete randomized design was arranged to be conducted with three replications in this investigation. The findings demonstrated that each Cd dose had detrimental effects on seed germination and seedling growth in all rice varieties. All varieties showed different reactions to priming treatments. Hydropriming showed the most positive impact on germination, while priming with KNO3 exhibited negative effects for all rice varieties. The Cd content of plant roots were higher than the shoots. It was observed that the lowest Cd content was detected in the shoots and roots of plants which were pre-treated with SA as compared to other priming applications. More than 50 ppm of cadmium was harmful because it lowered morphological features. However, seed hydropriming partially corrected these effects. For Cd stress resistance, the rice genotype Kızıltan continued to outperform the other cultivars studied. [ABSTRACT FROM AUTHOR]

The dry matter ratio of Ranunculus constantinopolitanus 90.5-90.6%, crude protein ratio 13.1-13.4%, ADF ratio 34.9-35.9%, NDF ratio 47.3-48.9%, ADP ratio 0.33-0.37%, Ca ratio 1.16-1.22%, Mg ratio 0.37-0.38%, P ratio 0.26-0.27% and K ratio varied between 0.94-0.97%. As a result of the germination test with plant seeds, it was determined that 87 seeds germinate at the end of the 21st day, and the total germination rate was 21.8%. Detection of toxic substances and other nutrients contained in this plant with future studies will provide better recognition of this plant.

Forest fires are a frequent event in Mediterranean climate-dominated regions and have great importance on succession. This reality, which is also valid for forest trees, facilitates the regeneration of some species and causes some species to lost their presence in the area. Therefore; it is important to know the fire ecology of the each species. To know the effects of the fires on seed viability and germination; will facilitate the development and follow-up of existing species in the area. In this study, different heat shocks (70, 90, 110 and 130 ºC) at different durations (1 and 5 min.) were applied on seeds obtained from 15 different populations of Anatolian black pine [Pinus nigra J.F. Arnold ssp. pallasiana (Lamb.) Holmboe] from four different main breeding zones and germinations was followed. As a result, the treatment of 130°C-5 min. reduced germination ability of seeds. However, it was found that Anatolian black pine seeds can withstand high heat shocks without affecting the germination ability up to 110 ºC. In addition, it was found that 1 min. heat shock application did not decrease the germination ability. Among the populations Sütçüler-Tota (1600 m), Çal-İnceler (1560 m), Alaçam-Gölcük (1050 m) Bursa (950 m) and Domaniç-Dereçarşamba (1400 m) populations have shown the highest germination capacity as general mean. And the treatments of 70ºC-5 min, 90ºC-1 and 5 min, 110ºC-1 min and 130ºC-1 min among the applications increased germination percentage according to the control group.
