Investigation was carried out at the Institute of Horticulture, Lithuanian Research Centre for Agriculture and Forestry in 2012-2013. The objective of investigation was sweet pepper cultivars - 'Reda' and 'Alanta'. The plants were sprayed with botanical ("Zytron" and "Funres" - four times) and homeopathic extracts - "Silicea" (two times in early plant stage) and "Carbo vegetabilis" (two times at the middle of plant vegetation) of different solution concentrations every 10 days. It was established that the preparations influenced the yield and biochemical composition of sweet pepper fruit. The obtained results showed that the plants sprayed with the biological extract "Funres" had the highest yield (7.1-7.2 kg m-2). It was established that the average amout of soluble solids in the sweet pepper fruit reached 6.9-9.8% respectively. The highest amount of ascorbic acid (178-181.5 mg 100 g-1) was detected in the fuit of cultivar 'Alanta', which had been sprayed four times with the botanical extracts "Zytron" and "Funres".

Investigation was carried out at the LRCAF Institute of Horticulture in 2012. The aim of this experiment was to evaluate delayed sowing time influence on tomato yield and quality. The object of investigation was tomato variety -- 'Tamina'. It's a medium early, indeterminate type variety, growing up till 2 meters in height with mid-sized (75 g) fruits. Tomato seeds were sown at four different times (29-03-2012; 05-04-2012; 04-12-2012 and 19-04-2012) in heated greenhouse. On the 5th of June tomato seedlings were planted in natural soil in polyethylene non-heated greenhouse as a second culture. The experiment was conducted in three replications. Harvesting field area was 2.1 m². Dry matter and soluble solids content of tomato fruit were determined at the LRCAF Institute of Horticulture in Biochemistry and Technology Laboratory, applying non-destructive Near Infrared Spectroscopy (NIR). The results showed that the earliest sown tomatoes had the earliest yield, but time between germination and the first yield was 3 days longer in comparison with latest sowing tomatoes. Tomatoes sown on the 29th of March and on the 5th of April stood out with the highest total and marketable yields. Tomato sowing time delay gradually increased the amount of non-marketable yield and non-marketable amount of fruits. The earliest sown tomatoes had the largest fruits and sowing delay had negative effect on fruit size. Sowing time also influenced the amounts of dry soluble solids and soluble solids content in tomato fruits. [ABSTRACT FROM AUTHOR]

Lithuanian and foreign cultivars of onions were investigated at the Lithuanian Institute of Horticulture of the organically grown experimental field in 2008-2009. Productivity and biochemical composition of edible onion is influenced by genetype and conditions of growing. Investigations showed that onions 'Babtu didieji' were more productive (yield - 15.1 t ha-1) than other investigated cultivars and produced turnips of average size (121. 0 g). In 2008-2009 during onion vegetation and storage there were found diseases, which were caused by pathogenic pathogenic fungi of the genera Peronospora and Botrytis. Botrytis squamosa fungi injured onion leaves and caused leaf blight. [ABSTRACT FROM AUTHOR]

The object of this study was to evaluate the effect of simulated late frosts on physiological indices of pea plants. Vegetative experiments were carried out in Laboratory of Plant Physiology at the Lithuanian Institute of Horticulture in phytotron complex in 2008. Investigated plants: Pisum sativum L. var. `Pinochio' and var. `Cud Kelvedonu'. Plants were exposed to frost two and four days, by simulating frosts for three and a half hour. Different influence on plant physiological parameters of two and four days frosts was observed. The reaction of peas to stress depended on their genotype. Two and four days frost adversely affected photosynthesis system of pea var. `Pinochio'. Fructose and glucose abundantly accumulated in the leaves of pea var. `Pinocchio' after two and four days frost. Hexoses participate in tolerance to frost processes. Pea var. `Cud Kelvedonu' was tolerant to frost and frosts of different length had not essential impact. [ABSTRACT FROM AUTHOR]
