title: [Effect of exogenic folic acid on the yield and amino acid composition of the seeds of Pisum sativum L. and Hordeum vulgare L].
abstract: Effects of exogenous folic acid (FA) on the productivity of Pisum sativum L. and Hordeum vulgare L. have been studied. After flowering, the plants were treated with optimum concentration of FA (25 mg per 1 water). This treatment increased the weight of the seeds by 17-19% (samplings of 1000 pcs were compared), whereas the yield became 26-29% higher. Amino acid analysis revealed a notable increase in the content of folate-dependent amino acids (e.g., glutamate, glycin, and methionine). Analysis of total folate content demonstrated that tetrahydrofolic coenzymes were significantly increased in experimental seeds. Treatment of the plants with exogenous FA increased both the content of chlorophyll in the leaves and their continuance of function. The results obtained led to the conclusion that FA treatment increases the productivity of pea and barley, by affecting the yield, weight, and quality of the seed.
