Dynamics of accumulation of oil and fatty acids in the seeds crops of brassicaceae

The aim of the research is to study the dynamics of the accumulation of oil and fatty acids in seeds the oil of Brassicaceae crops in relation to the conditions of the Middle Volga region. The object of research was the Camelina sativa variety Yubilyar and the Sinapis alba variety Lyutsiya. Samples for analysis were taken every 10 days, starting from the moment of seed formation. In the initial stages of seed formation in Camelina and Sinapis alba, the fat content is almost the same and varies from 3.2 to 3.8%. Then the intensity of the oil-accumulating process in crops of cabbage changes and the fat content the seeds increases by 2-3 times. The maximum oil content (27.2 and 39.8%) in of Sinapis alba and of Camelina sativa is noted when the seeds reach full maturity. As the seeds mature, the synthesis of linoleic and linolenic acids increases, their content decreases by 29.1 and 17.2%. The content of oleic acid in oil is also reduced by 9.0% in camelina and only 4.6% in mustard. The content of erucic acid increases, regardless of culture.
