Effect of irrigation on the oil content and fatty acid composition of some sunflower seeds

摘要

The effect of irrigation on the seed yield, oil yield, and oil composition of sunflower in populations of Ekiz1 and VNIIMK 8931, a mixture of N_2, N_3, and N_4 lines, and a synthetic variety obtained from these lines has been studied. The major fatty acid was found to be oleic acid, in addition to linoleic, palmitic, and stearic acids. Irrigation increased seed yield, oil yield, and oil content of all samples. In two of them, the synthetic variety and VNIMK 8931, the increase was found to be statistically significant. In addition, irrigation of the samples did not increase significantly the amount of oleic and linoleic acids. On the contrary, the amount of linoleic acid in the mixture of N_2, N_3, and N_4 lines and oleic acid in VNIMK 8931 decreased statistically significantly.
