摘要

The aim of this study was to determine the influence of exogenous methyl jasmonate (MJ) on the content and composition of flavonoids (isoflavones) in extracts from hypocotyls (with cotyledons) and radicles of yellow lupine (Lupinus luteus L.) var. Polo and in extracts from radicles of narrow-leafed lupine (Lupinus angustifolius) var. Graf. Lupine seeds were harvested when fully ripe. Two months after harvest, the effect of various MJ concentrations (10(-6) M to 10(-3) M) on seed viability, seed vigor and the content and composition of flavonoids in extracts from seedlings that emerged from germinated lupine seeds (72 h, 20 degrees C) was determined. At high concentrations (10(-4) M to 10(-3) M), MJ suppressed the germination rate and germination capacity of seeds and decreased the growth rate of seedlings of the analyzed varieties of yellow and narrow-leafed lupines in the first 5 days of growth. In seedlings, MJ significantly increased the content of isoflavones (including daidzin, genistin, daidzein, and genistein) in 3-day-old hypocotyls (with cotyledons) and radicles of yellow lupine. This correlation was also observed in the hypocotyls (with cotyledons) and radicles of 3-day-old narrow-leafed lupine seedlings treated with MJ. Narrow-leafed lupine seeds were more sensitive to exogenous MJ then yellow lupine seeds during germination.
