BIOACTIVE COMPOUNDS AND ANTIOXIDANT CAPACITY FROM FIVE TYPES OF SEEDLINGS

After germination process, the green seedlings accumulate important quantities of bioactive compounds such as: enzymes, vitamins, minerals, chlorophylls and nutrients. The current study presents a comparison between different bioactive compounds and their antioxidant capacity, after the seedling germination and growth of five seeds (arugula, lentil, wheat, beans and mustard) both on soil, in a pot (natural system), and directly on cotton wool soaked, in water (artificial system). In this study the carotenoids content and the antioxidant capacity were analysed. The data of the present study showed that the highest amount of zeaxanthin and β - carotene was found in cultivars of wheat grown in natural system, while the highest antioxidant activity was found in cultivars of wheat, lentils and beans, though in this case with no statistical differences between the systems. The results show statistical differences between the values of bioactive compounds in the five types of seedlings but also in the values obtained for the same seedlings in different systems. The best cultivars for improving the nutritional quality for human consumption are wheat seedlings followed by lentil ones

INFLUENCE OF VINE VIGOR GROWTH ON CODREANCA (BLACK MAGIC) TABLE GRAPES QUALITY

The stressful climatic conditions of the last years have led to the need to pay more attention to the native varieties, which are adapted to the local conditions and ensure the obtaining of quality harvests. Autochthonous varieties of table grapes have dietary properties, attractive exterior appearance and excellent taste qualities.This work presents a 3-year study of the variability of grape composition of Codreanca (Black Magic) – a Moldavian grape variety, in a vineyard located in Purcari (Republic of Moldova). Grapevine were different pruned according to growth vigor: low - 18 – 22 buds (1 spur and 2 canes); medium vigor – 24 - 28 buds (1 spur and 3 canes) and high vigor – 30 - 34 buds (2 spurs and 4 canes). Climatic conditions and growth vigor had an important influence on vine fertility and productivity. Results showed that vine balance at which vegetative and reproductive growth can be sustained with adequate fruit production and desired fruit quality was found to be for Codreanca on vines with medium vigor. Grapes harvested from medium vigor vine recorded optimum values of quality (sugar and acid content, sugar/acid ratio) and cluster indexes (average weight, lenght and width, berry lenght and width, berry weight, grape and berry composition, cluster structure index, berry index, berry composition index, berry sfericity and cluster compactness). Viticultural practices used by grape growers can also increase or decrease vine growth as needed, to obtain high quality production
