Salt stress affects all phases of rapeseed growth and development, but seed germination and seedling growth are the most sensitive. In our previous studies, we have evaluated effect of salt stress on the germination process of rapeseed in controlled laboratory conditions. We tested eight rapeseed cultivars Banaćanka, Jasna, Kata, Zorica, Slavica, Anna, Ilia and Zlatna under salt stress (100, 150, 200 and 250 mmol/L NaCl). All tested cultivars had a certain level of tolerance to low NaCl treatments, while at higher concentrations significant damage was observed, which was reflected in the reduction of growth and the appearance of necrosis. Banaćanka and Zorica had the highest germination values in all salt stress levels, while Jasna and Zlatna varieties had the highest germination reduction. Between the tested genotypes, obvious differences were observed when analyzing the activity of antioxidant enzymes superoxide dismutase and guaiacol peroxidase (SOD, GPx), the amount of non – enzymatic antioxidants reduced glutathione (GSH) and the intensity of lipid peroxidation (LP), both in seedlings shoot and in the root. Induction of SOD activity by different concentrations of NaCl was observed in all examined cultivars. Tolerant varieties showed increased activity of antioxidant enzymes and in regard to this, higher SOD activity was found in cultivars Jasna and Kata. In all examined cultivars, there was a gradual increase in the intensity of LP with a higher concentration of NaCl. Cultivar Banaćanka showed the highest (237.21%) increase at the highest salt stress level, while Kata showed the lowest (147.73%), compared to the control. So far, over 500 drought and/or high-salinity stress-inducible genes were identified in B. napus by using different approaches. Some of the rapeseed genotypes, which have been identified in our study as potential sources of salt and other abiotic stresses tolerance (Banaćanka, Anna, Zorica) are selected for further study of the role of stress-i

The purpose of this study is to determine the quality of oilseed rape seeds, produced at various locations, immediately after harvest and after a one-year storage period under controlled and uncontrolled conditions. The experimental testing was performed on seeds of five winter oilseed rape varieties produced at two localities (Rimski Šančevi and Pančevo). Following harvest and a one-year storage period, the seed quality was determined under laboratory conditions using standard germination tests. Seed germination, seedling length and vigour index were determined after seven days. The seed germination, length of seedling and vigour index values of the seeds produced at both localities were lower after one year of storage. Differences obtained between the seeds stored under controlled and uncontrolled conditions were not statistically significant. The seeds with higher initial values of all the tested parameters proved better under storage conditions., Cilj istraživanja je bio da se utvrdi kvalitet semena neposredno posle žetve i nakon godinu dana skladištenja, u kontrolisanim i nekontrolisanim uslovima, kod semena proizvedenog na različitim lokalitetima. Ispitivanja su izvedena na semenu, pet sorti ozime uljane repice, proizvedenog na dva lokaliteta (Rimski Šančevi i Pančevo). Nakon žetve i godinu dana skladištenja, u laboratorijskim uslovima, utvrđen je kvalitet semena primenom standardnog laboratorijskog metoda. Nakon 7 dana utvrđeni su klijavost semena, dužina ponika i vigor indeks. Klijavost semena kod sorata proizvedenih na lokalitetu Rimski Šančevi kretala se 91,00 - 95,50%. Nakon godinu dana starenja kod semena čuvanog u kontrolisanim uslovima klijavost je bila niža i iznosila je 85,00 - 91,75%, dok je kod semena čuvanog u nekontrolisanim uslovima klijavost iznosila 84,50 - 90,75%. Klijavost semena kod sorata proizvedenih na lokalitetu Pančevo je bila značajno manja i neposreno posle žetve je iznosila 73,75 - 82,50%. Nakon godinu dana starenja klijavost je statistički značajno opala i kod semena čuvanog u kontrolisanim (51,25 - 71,0%) i nekontrolisanim uslovima (53,50 - 71,25%). Dužina ponika i vigor indeks su bili niži nakon godinu dana sklaištenja kod semena proizvedenog na oba lokaliteta. Razlike dobijene između semena čuvanog u kontrolisanim i nekontrolisanim uslovima nisu bile statistički značajne. Seme koje je imalo više početne vrednosti ispitivanih parametara bolje je podnelo uslove sklaištenja.

Osetljivost uljane repice prema količini soli u zemljištu nije ista u svim fazama njenog porasta. Najosetljivije su biljke u fazi klijanja i nicanja. Cilj ovog istraživanja je bio da se utvrdi uticaj različitih koncentracija soli NaCl (0 mmol/l,125 mmol/l,175 mmol/l,250 mmol/l) na klijavost semena, srednje vreme klijanja semena, vigor indeks, dužinu ponika i svežu masu ponika kod semena tri genotipa uljane repice (Anna, Slavica, Ilia). Iz dobijenih rezultata se uočava da niže koncentracije NaCl biljke mogu da tolerišu i one ne utiču negativno, dok visoke koncentracije ispoljavaju negativan uticaj na ispitivane parametare., Sensitivity of oilrape towards the quantity of the salt in the soil is not the same in all its growth stages. The most sensitive are the plants in the initial stages – germination and emergence. The aim of this investigation was to determine the influence of various NaCl concentrations (0 mmol/l,125 mmol/l,175 mmol/l,250 mmol/l) to seed germination, means daily germination seed, vigor index, seedling length and fresh mass of seedling in the seed of three oilrape genotypes (Anna, Slavica and Ilia). From the obtained results it can be seen that plants can tolerate lower NaCl concentrations, which have no negative effects, while high NaCl concentrations exert negative effects on the tested parameters.

Oilrape is used for human consumption, domestic animal consumption, for biodiesel production, as bee pasture and as an important green manure. This crop is tolerant to many soil types (including saline soils) in the growing regions across the globe. Testing was done on three oilrape winter varieties: Ana, Slavica and Ilia. The influence of salinity on seed quality was determined after the harvest using standard laboratory methods under laboratory conditions. Seed germination in the control ranged from 92.75 % do 96 %. As NaCl concentration increased from 150 mmol/l to 250 mmol/l, germination decreased, and statistically the lowest values were obtained at the concentration of 300 mmol/l in Slavica and Ilija varieties (57-84 %). In all studied genotypes, the first seedlings emerged after three days of testing in the control and at NaCl concentrations of 75 mmol/l, 100 mmol/l, 150 mmol/l and 200 mmol/l. The seed germinated on the medium moisturized with 250 mmol/l NaCl started to germinate after four days of testing, while the seed germinated on the medium moisturized with 300 mmol/l NaCl started germination after five days. The length of seedlings was statistically the most significant in the control in all three varieties. Statistically the lowest values were obtained in the seedlings at NaCl concentration of 300 mmol/l. For successful production under stress conditions, adaptable genotypes which have pronounced positive interaction with environmental conditions should be chosen., Uljana repica je biljna vrsta koja je tolerantna na mnoge tipove zemljišta u regionima gajenja širom sveta, koja dobro podnosi zaslanjena zemljišta. Ispitivanja su izvedena na tri sorte ozime uljane repice: Ana, Slavica i Ilia. Nakon žetve, utvrđen je uticaj zaslanjenosti na kvalitet semena primenom standardnog laboratorijskog metoda. Filter papir je kvašen destilovanom vodom (kontrola) i različitim koncentracijama NaCl (75 mmol/l, 100 mmol/l, 150 mmol/l, 200 mmol/l, 250 mmol/l i 300 mmol/l). Nakon 7 dana utvrđeni su klijavost semena, brzina klijanja semena i dužina ponika. Klijavost semena u kontroli se kretala od 92.75% do 96%. Sa povećanjem koncentracije NaCl od 150 mmol/l do 250 mmol/l klijavost se smanjivala i statistički najniže vrednosti dobijene su na koncentraciji od 300 mmol/l kod sorti Slavica i Ilija (57%-84%). Kod svih ispitivanih genotipova prvi klijanci su se pojavili nakon tri dana ispitivanja i to u kontroli i na koncentracijama NaCl od 75 mmol/l, 100 mmol/l, 150 mmol/l i 200 mmol/l . Seme naklijavano na podlozi kvašenoj sa 250 mmol/l NaCl počelo je da klija nakon 4 dana ispitivanja, a nakon 5 dana na podlozi kvašenoj sa 300 mmol/l NaCl. Dužina ponika je bila statistički značajno najveća u kontroli, kod sve tri sorte. Statistički značajno najniže vrednosti su dobijene kod ponika na koncentraciji 300 mmol/l NaCl. Za uspešnu proizvodnju u stresnim uslovima treba odabirati genotipove koji su adaptabilni i imaju izraženu pozitivnu interakciju sa uslovima spoljne sredine.

According to the surfaces on which the oil rape is grown, it is considered the third most important oil crop of moderate climate zone in the world today. The aim of this paper was to determine the seed viability by application of both the standard laboratory test and the vigor tests. Testing was done using 9 oil rape genotypes (three winter varieties: Slavica, Zlatna and Ilija; three spring varieties: Mira, Jovana and JR-NS-7; three hybrids NS-UR 4, NS-UR 6 and NS-UR 13). Seed germination, seedling growth parameters, fresh seedling mass, and vigor index were determined using standard laboratory (SL) test, accelerated aging (AA) test, and controlled deterioration (SD) test. With applied SL test, on average, statistically significantly higher values for all tested parameters were obtained in comparison to AA and CD tests. By calculating the vigor index genotypes Zlatna, JR-NS 7, NS-UR 4, NS-UR 6 and NS-UR 13 were singled out, in which statistically significantly higher values were obtained with SL in relation to AA and CD tests., Danas je uljana repica najvažnija uljana biljka umerenog klimata i po površinama na kojima se gaji zauzima treće mesto među uljaricama u svetu. Zbog svoje raznovrsne primene, površine pod ovom kulturom se povećavaju iz godine u godinu, pa je potrebno obezbediti dovoljne količine kvalitetnog semena. U laboratorijskim uslovima se životna sposobnost semena ispituje različitim metodama. Cilj rada je bio da se utvrdi životna sposobnost semena primenom standardnog laboratorijskog testa i vigor testova. Ispitivanja su izvedena na 9 genotipova uljane repice (tri ozime sorte: Slavica, Zlatna i Ilia; tri jare sorte: Mira, Jovana i JR-NS- 7; tri hibrida NS-UR 4, NS-UR 6 i NS-UR 13). Utvrđena je klijavost semena, dužina ponika, sveža masa ponika i vigor indeks primenom standardnog laboratorijskog (SL) testa, testa ubrzanog starenja (AA) i testa kontrolisanog propadanja (CD). Primenom SL testa u proseku dobijene su statistički značajno više vrednosti za sve ispitivane parametre u odnosu na primenu AA i CD testa. Izračunavanjem vigor indeksa izdvojili su se genotipovi Zlatna, JR-NS 7, NS-UR 4, NS-UR 6 i NS-UR 13 kod kojih su se javile statistički značajno više vrednosti primenom SL testa u odnosu na primenu AA i CD testa. Uzorci navedenih genotipova su pokazali manju tolerantnost na nepovoljne uslove visoke temperature i visoke vlažnosti vazduha. Vigor testovi su korisni jer nam daju pouzdaniju informaciju o kvalitetu semena, a naročito ih treba koristiti ako se setva vrši u vreme pojave nepovoljnih uslova u vreme nicanja i ako je potrebno vršiti skladištenje i čuvanje semena za narednu vegatacionu sezonu.

Rapeseed is an important industrial plant in the world. In Vojvodina region of Serbia it is grown on well aerated and deep soils. Most often it is sown with the distance between the rows of 25 cm, and 5-6 cm within the row. The trial with three winter rapeseed genotypes (Banaćanka, Slavica and NS-H-2) was set up at Rimski Šančevi (Vojvodina) during growing seasons of 2009/2010 and 2010/2011. Seed was sown with inter row spacing of 25 cm, and spacing within the rows of 5 cm, 8 cm, 10 cm and 16 cm. The following parameters were tested upon harvesting: seed germination, 1000 seed weight, test weight, seed yield, oil content and total protein in seed. No effect of planting density was observed on rapeseed seed quality produced in 2009/10 and 2010/11, which should be kept in mind when determining the quantity of seed required for sowing., Uljana repica je značajna industrijska biljka u svetu. U Vojvodini se najčešće gaji na dobro aerisanim i dubokim zemljištima. Setva se najčešće vrši sa razmakom između redova 25 cm, a u redu 5-6 cm. Ogled sa tri genotipa ozime uljane repice (Banaćanka, Slavica i NS-H-2) je postavljen na Rimskim šančevima (Vojvodina) u vegetacionoj sezoni 2009/2010. i 2010/2011. Setva je izvršena u redove sa međurednim razmakom 25 cm i razmakom u redu od 5 cm, 6 cm, 8 cm, 10 cm i 16 cm. Nakon žetve ispitani su sledeći parametri: klijavost semena, masa 1000 semena, zapreminska masa, prinos semena, sadržaj ulja i ukupnih proteina u semenu. U našim ispitivanjima nije utvrđen uticaj sklopa na kvalitet semena uljane repice proizvedenog u vegetacionoj sezoni 2009/10. i 2010/11. što treba imati u vidu prilikom određivanja potrebne količine semena za setvu.

Due to its composition the oilseed rape is widely used in the production of oil, animal feed and biodisel production. Due to a wide range of rapeseed use, the aim of this paper was to determine the influence of genotype, production year and planting density on seed germination, seed moisture content, mass of 1000 seed, hectoliter mass, seed yield per plot, and oil and protein content in the seed. Tests were carried out on four rapeseed genotypes sown at a distance of 5 cm (80 plants/m2), 10 cm (40 plants/m2), 15 cm (27 plants/m2) and 20 cm (20 plants/m2) within the raw during 2007/2008 and 2008/2009 vegetation period. Seed germination, hectoliter mass and seed yield depended on production year, mass of 1000 seeds depended on genotype, plant density and production year, while the oil and protein content depended on genotype and production year., Uljana repica, zbog svog sirovinskog sastava nalazi veliku primenu u proizvodnji ulja, ishrani domaćih životinja i proizvodnji biodizela. Cilj istraživanja je bio da se utvrdi uticaj gustine setve, tj. različitog razmaka biljaka unutar reda na kvalitet semena i komponente prinosa četiri sorte ozime uljane repice proizvedene u dve vegetacione sezone. Ispitivanja su izvršena na četiri genotipa uljane repice (Slavica, NS-L-7, Artus, NS-L-21), posejane sa razmakom u redu od 5 cm (80 biljaka /m2), 10 cm (40 Biljaka /m2), 15 cm (27 biljaka /m2) i 20 cm (20 biljaka /m2) u vegetacionim sezonama 2007/2008. i 2008/2009. godina. Nakon žetve utvrđeni su prinos semena po parceli, hektolitarska masa, masa 1000 semena, sadržaj vlage u semenu, klijavost semena, sadržaj ulja i sadržaj ukupnih proteina. Klijavost semena ispitivanih genotipova uljane repice proizvedene u vegetacionoj sezoni 2007/2008. je bila viša od klijavosti semena proizvedenog 2008/2009. Uticaj različitih gustina setve, na ispitivani parametar, nije utvrđen. Sadržaj vlage nije zavisio od genotipa, niti od gustine setve. Masa 1000 semena zavisila je od godine proizvodnje i genotipa. U zavisnosti od godine proizvodnje, ispitivani genotipovi, su različito reagovali na gustinu setve i dobijeno je seme sa različitom masom 1000 semena. Prinos semena uljane repice nije zavisio od genotipa i gustine setve, a zavisili su od godine proizvodnje. Sadržaj ulja i proteina u semenu zavisio je od genotipa i godine proizvodnje.

Sunflower is a plant species with a prominent period of seed dormancy. Physiological maturation period can be accelerated under laboratory conditions using methods for breaking seed dormancy such as: previous cooling at 5-10°C, previous heating at 30-35°C, gibberellic acid treatment, KNO3, ethrel, etc. The aim of this study was to determine the duration of seed dormancy period of different sunflower hybrids and parent lines produced in Serbia, and to determine which of the methods for breaking seed dormancy gives the best results. Studies were carried out on five commercial sunflower hybrids and their parental components. Seed germination was determined after harvesting using standard laboratory methods and tetrazolium tests. The following methods were used for seed dormancy breaking: low temperature treatment of 5-10°C, high temperature treatment of 30-35°C, and treatment with gibberellic acid. The tests were performed in the period of 30, 50, and 90 days after harvesting. The application of gibberellic acid method gave the lowest values of seed germination, while statistical significant differences between the control and method of low and high temperatures were not found. Sunflower hybrids Sremac, Duško, NS-H-111, Velja and Branko, as well as the female lines of hybrid NS-H-111, and male lines of hybrids Sremac and Velja had no prominent seed dormancy 30 days after harvesting. Seed dormancy in female lines of hybrids Sremac, Duško, Velja and Branko and male lines of hybrids Duško, NS-H-111 and Branko was decreased 90 days after storage, but it was not completely removed.

Seme obeležava početak biljne proizvodnje i zato je obezbeđivanje njegovog kvaliteta prioritet savremenog semenarstva i preduslov za visoke prinose svih biljnih vrsta. Izučavanje mehanizma funkcionisanja semena, zatim redovne fiziološke, biohemijske i u novije vreme molekularne analize semenskog materijala treba da pruže uvid u kvalitet i daju čvrstu osnovu za unapređenje oplemenjivačkih programa i jačanje sistema kontrole u procesu semenske proizvodnje (Milošević et. al., 2007). Utvrđivanje kvaliteta semena vrši se primenom standardizovanih metoda, koje se menjaju u skladu sa naučnim saznanjima iz oblasti fiziologije semena. Pored toga novi tehnološki procesi dorade semena mogu da utiču na promenu metode, u skladu sa zahtevima određenih biljnih vrsta. Seme posle žetve, u procesu dorade, treba da se očisti od fizičke nečistoće, semena drugog kulturnog bilja i korova, kao i od semena lošeg kvaliteta i odredi u partije (Basra 2006). Partija je specifična količina semena, koja se fizički može identifikovati i za koju se, na osnovu toga, može izdati Sertifikat o ispitivanju. Sertifikat o ispitivanju je pokazatelj kvaliteta semena, a on obuhvata ispitivanje čistoće, klijavosti i sadržaj vlage, određivanje mase 1000 semena, ispitivanje zdravstvene ispravnosti i utvrđivanje životne sposobnosti semena. Da bi se ovi elementi utvrdili potrebno je izvršiti uzorkovanje semena.

At the time of soybean seed sowing in the field, a high soil moisture, low soil and air temperatures, and crasts formation may occur, which can lead to slow germination, poor seedling establishment, and in some cases to loss of seed vigor. Due to the importance and prevalence of soybean the aim of this study was to determine the quality and seed viability of different genotypes produced at three locations in Vojvodina during 2009 and 2010. Eight soybean varieties (Afrodita, Valjevka, Balkan, Novosadjanka, Ravnica, Ana, Vojvodjanka and Venera) produced in Vrbas, Senta and Inđija during 2009 and 2010 were tested. Seed germination was determined using Standard laboratory test, and vigor tests (cold test, and accelerated aging test). Studied genotypes baheved differently in different years and at different localities. Genotype Venera achieved high germination values in all applied tests in 2009, while genotype Afrodita had high values of the tested parameter when conventional laboratory test was applied, and the lowest values were recorded when vigor tests were applied. Values obtained in 2010 when all tests were applied were above the prescribed minimum. Locality of Vrbas proved to be more favorable for seed production in relation to localities of Indjija and Senta due to better rainfall distribution., U vreme setve soje, u polju, može da se javi visoka vlažnost zemljišta, niska temperatura zemljišta i vazduha i pokorica, što može da dovede do usporavanja nicanja, formiranja slabog ponika, a u nekim slučajevima do gubitka životne sposobnosti semena. Zbog značaja i rasprostranjenosti soje cilj rada je bio da se utvrdi kvalitet i životna sposobnost semena, različitih genotipova, proizvedenih na tri lokaliteta Vojvodine u toku 2009 i 2010. godine. Ispitivanja su izvršena na 8 sorata soje (Afrodita, Valjevka, Balkan, Novosadjanka, Ravnica, Ana, Vojvodjanka i Venera) proizvedenih u Vrbasu, Senti i Inđiji u 2009 i 2010. godini. Kod svih uzoraka utvrđena je klijavost semena primenom standardnog laboratorijskog metoda i vigor testova (hladni test i test ubrzanog starenja). Ispitivani genotipovi su se različito ponašali u pojedinim godinama i lokalitetima. Genotip Venera se izdvojio po visokim vrednostima klijavosti semena dobijenim u 2009. godini kod svih primenjenih testova, dok je genotip Afrodita imao visoke vrednosti ispitivanog parametra primenom standardnog laboratorijskog testa, a primenom vigor testova su konstatovane najniže vrednosti. U 2010. godini dobijene vrednosti, primenom svih testova, su bile iznad propisanog minimuma. Lokalitet Vrbas se pokazao kao povoljniji za semensku proizvodnju u odnosu na lokalitet Senta i Indjija, zbog boljeg rasporeda padavina.

International seed trade considers seed germination as the main indicator of the seed quality. Different results of seed germination under laboratory conditions and emergence in the field encouraged the development of the concept of the seed vigor and the term of vigor. Seed viability or vigor presents a set of those traits that affect seed germination and the establishment of strong and healthy seedlings under different environmental conditions. The aim of this work was to determine the effect of locality and production year on germination and vigor of soybean seed. The testing was performed on 6 soybean varieties (Valjevka, Bojana, Balkan, Novosađanka, Vojvođanka i Morava) produced in the towns of Inđija and Vrbas in 2009 and 2010. The seed germination of all samples was determined by using standard laboratory and vigor tests (Cold test and Accelerated aging test). When the standard laboratory test was applied the seed germination of all tested varieties produced in 2009 in Inđija ranged from 78% to 87%, and from 94% to 99% in Vrbas. The germination of seeds produced in 2010 in both localities was higher in all tested varieties in relation to 2009. When the accelerated aging test was applied the germination of seeds produced in Inđija in 2009 was statistically significantly lower (67-85%) in all tested varieties in comparison to seed germination obtained by the standard laboratory test (78-87%). The seed germination obtained by the application of the cold test was statistically significantly lower (25-90%) for the seed produced in Inđija in comparison to the value obtained for the seeds produced in Vrbas (80-97) for both years of production., Međunarodna trgovina semena, kao osnovni pokazatelj kvaliteta uzima klijavost semena. Različiti rezultati ispitivanja klijavosti semena u laboratorijskim uslovima i nicanja u polju podstakli su razvoj koncepta životne sposobnosti semena i pojma vigora. Životna sposobnost semena ili vigor predstavlja skup onih osobina semena koje utiču na klijavost semena i formiranje snažnog i zdravog ponika u različitim uslovima spoljašnje sredine. Cilj rada je bio da se utvrdi uticaj lokaliteta i godine proizvodnje na klijavost i vigor semena soje. Ispitivanja su izvršena na 6 sorata soje (Valjevka, Bojana, Balkan, Novosađanka, Vojvođanka i Morava) proizvedenih u Inđiji i Vrbasu u 2009 i 2010. godini. Kod svih uzoraka utvrđena je klijavost semena primenom standardnog laboratorijskog metoda i vigor testova (hladni test i test ubrzanog starenja). Primenom standardnog laboratorijskog metoda klijavost semena, kod svih ispitivanih sorata na lokalitetu Inđija, proizvedenih u 2009. godini, se kretala od 78% do 87%, a na lokalitetu Vrbas od 94% do 99%. Klijavost semena proizvedenog u 2010 godini, na oba lokaliteta je bila veća, kod svih ispitivanih sorti, u odnosu na 2009. godinu. Primenom testa ubrzanog starenja klijavost semena proizvedenog na lokalitetu Inđija u 2009. godini, kod svih ispitivanih sorata je bila statistički značajno niža (67-85%) u odnosu na klijavost semena dobijenu standardnim laboratorijskim metodom (78-87%). Klijavost semena dobijena primenom hladnog testa, u obe godine proizvodnje, na lokalitetu Inđija (25-90%) je bila statistički značajno niža u odnosu na vrednosti dobijen za seme proizvedeno na lokalitetu Vrbas (80-97).

Common vetch (Vicia sativa L), hairy vetch (Vicia villosa Roth), and Pannonian vetch (Vicia pannonica Crantz) are the most often grown varieties in the production area of Serbia. The most important problem in the production of vetch seed is lodging. Yield and seed quality in lodged crops can be significantly reduced. Therefore, it is very important to accurately estimate the quality, and viability of produced seed. Common vetch, hairy vetch and Pannonian vetch were submitted to vigor testing using standard laboratory test, cold test, Hiltner test, and three variants of accelerated aging tests (39°C,72 h; 39°C, 96 h; 45°C, 48 h). When the standard laboratory test was applied, the common vetch achieved the highest seed germination value of 90%, while decreased rate of seed germination was due to unfavorable conditions applied in vigor tests. Above ground seedling growth parameters were the lowest when Hiltner test was applied. Length and mass of the root system were the lowest when accelerated aging test was applied. Hairy vetch obtained the lowest values for all tested parameters when Hiltner test was applied. Application of different variants of accelerated aging tests indicated that tested parameters were not dependent on the applied temperature, while reduction in legumes vigor was under the influence of temperature duration., U proizvodnom području Srbije najviše se gaji obična grahorica (Vicia sativa L), zatim maljava grahorica (Vicia villosa Roth), pa panonska grahorica (Vicia pannonica Crantz). Najznačajniji problem u proizvodnji semena grahorice predstavlja poleganje. Prinos i kvalitet semena u poleglom usevu mogu biti značajno smanjeni. Zbog toga je vrlo bitno precizno utvrditi kvalitet proizvedenog semena, odnosno njegovu životnu sposobnost. Ispitivanje životne sposobnosti semena izvršeno je na običnoj, maljavoj i panonskoj grahorici primenom standardnog laboratorijskog testa, hladnog testa, Hiltner testa i tri varijante testa ubrzanog starenja (39°C,72 h; 39°C, 96 h; 45°C 48 h). Obična grahorica je imala najvišu vrednost klijavosti semena (90%) primenom standardnog laboratorijskog testa, dok su nepovoljni uslovi primenjeni u vigor testovima uticali na smanjenje klijavosti semena. Parametri porasta nadzemnog dela ponika su bili najniži kod primene Hiltner testa. Dužina i masa korenovog sistema je bila najniža primenom testa ubrzanog starenja. Kod maljave i panonske grahorice primenom Hiltner testa dobijene su najniže vrednosti za sve ispitivane parametre. Primena različitih varijanti testa ubrzanog starenja ukazuje da ispitivani parametri ne zavise od primenjene temperature, dok dužina trajanja temperature utiče na smanjenje životne sposobnosti semena grahorica.

Oilseed rape is an agronomically important species grown for seed that contains 40-48% oil and 18-25% proteins. Oilseed rape has high demands for nitrogen. The research was performed on four varieties of oilseed rape (Banaćanka, Valeska, Slavica and Express) developed at Institute of Field and Vegetable Crops in Novi Sad, during vegetative seasons 2007-2008 and 2008-2009. During vegetation, top dressing was applied with different amounts of KAN: control (0 kg N ha-1), 50 kg N ha-1, 100 kg N ha-1, 150 kg N ha-1 and the N quantity determination were performed applying the balancing method (also known as N-min method). Yield, 1000-seed weight, seed germination, oil and protein content were determined after harvest. Yield and seed germination depended on seed production year. 1000-seed weight depended on seed production year and genotype. Oil and protein content in seed depended on production year, genotype and amount of the N-fertilizer applied by top dressing., Uljana repica je značajna uljana biljka. Ona se gaji zbog semena koje sadrži 40-48% ulja i 18-25% belančevina. Uljana repica je azotofilna biljka. Ispitivanja su izvršena na četiri sorte uljane repice (Banaćanka, Valeska, Slavica i Express) proizvedene u vegetacionim sezonama 2007-2008. i 2008-2009. U toku vegetacionog perioda izvršena je prihrana različitim količinama KAN-a: kontrola (0 kg N ha-1), 50 kg N ha-1, 100 kg N ha-1, 150 kg N ha-1 a na osnovu balansne metode određena je količina azota (Nmin metoda). Nakon žetve utvrđeni su prinos semena, masa 1000 semena, klijavost semena, sadržaj ulja i sadržaj proteina u semenu. Prinos semena i klijavost semena su zavisili od godine proizvodnje. Masa 1000 semena je zavisila od godine proizvodnje i genotipa. Sadržaj ulja i proteina u semenu je zavisio od godine proizvodnje, genotipa i primenjenih količina azota u prihrani.

Weather conditions, especially amounts and the distribution of rainfalls, as well as, drought, significantly reduce yields and quality of soybean seed. Unfavorable effects of drought could be successfully eliminated by crop irrigation. Three commercial soybean cultivars, and two lines developed at the Institute of Field and Vegetable Crops in Novi Sad, were tested. The seed was produced under conditions of dry land farming and irrigation. Seed germination (Standard laboratory method) and seed vigor (accelerated aging test, Hiltner test and cold test) were tested under laboratory conditions. The germination value of the seed produced under irrigation (Standard laboratory method) was higher than the value of the seed produced under dry land farming conditions. Significant differences among tested cultivars and lines were observed by the application of this test. In the estimation of seed vigor, the highest values were obtained when accelerated aging test was applied. Significant differences among tested cultivars and lines and different production conditions were obtained for seed vigor by using Hiltner and cold tests., Vremenski uslovi, posebno količina i raspored padavina, te pojava suše značajno smanjuju prinose i kvalitet semena soje. Nepovoljan uticaj suše može se uspešno eliminisati navodnjavanjem useva. Ispitivanja su izvršena na tri komercijalne sorte i dve linije soje selekcionisane u Institutu za ratarstvo i povrtarstvo u Novom Sadu. Seme je proizvedeno u uslovima suvog ratarenja i navodnjavanja. U laboratorijskim uslovima izvršeno je ispitivanje klijavosti (standardni laboratorijski metod) i životne sposobnosti semena primenom vigor testova (test ubrzanog starenja, Hiltner test i hladni test). Seme proizvedeno u uslovima navodnjavanja imalo je veću klijavost primenom standardnog laboratorijskog metoda od semena proizvedenog u uslovima suvog ratarenja. Primenom ovog testa uočene su značajne razlike između ispitivanih sorti i linija. U oceni životne sposobnosti semena najviše vrednosti dobijene su primenom testa ubrzanog starenja. Značajne razlike u životnoj sposobnosti semena, između ispitivanih sorti i linija, i različitih uslova proizvodnje dobijene su primenom Hiltner i hladnog testa.
