Grapes is a highly valuable food product due to the presence in it of a number of biologically active substances, among which vitamins occupy a special place. One of the most important and studied in grapes is vitamin C (ascorbic acid). The ascorbic acid contained in plant tissue participates in redox metabolism, thereby increasing the resistance of plant organisms to infections and low negative temperatures. Studies aimed at determining the concentration of vitamin C in plant material are important both for breeding and for identifying the most sustainable competitive varieties.
The purpose of these studies is to study the content of vitamin C in grapes cultivated in the South of Western Siberia. Conducted research with 12 introduced varieties and selected forms growing in the collection of the Research Institute of horticulture of Siberia M.A. Lisavenko, allowed to establish dependence of accumulation of ascorbic acid in berries on weather conditions; to allocate 5 genotypes with high content of vitamin C. It is noted that the ripening period of berries, their color, as well as the direction of use and ecological and geographical origin of varieties and selected forms did not affect the accumulation of vitamin C in the period 2014–2016.
