Abstract 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 10-3M) 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 °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.

外源茉莉酸甲酯对黄、窄叶羽扇豆幼苗提取物中黄酮类化合物的萌发及含量及组成的影响

摘要 本研究的目的是确定外源茉莉酸甲酯 (MJ) 对黄羽扇豆 (Lupinus luteus L.) var. 下胚轴（带子叶）和胚根提取物中黄酮类化合物（异黄酮）的含量和组成的影响。马球和窄叶羽扇豆 (Lupinus angustifolius) var. 胚根的提取物。格拉夫。羽扇豆种子完全成熟时收获。收获后两个月，不同 MJ 浓度（10-6 M 至 10-3 M）对种子活力、种子活力以及发芽羽扇豆种子幼苗提取物中黄酮类化合物含量和组成的影响（72 小时，20° C) 确定。在高浓度（10-4 M 至 10-3 M）下，MJ 抑制了种子的发芽率和发芽能力，并降低了所分析的黄色和窄叶羽扇豆品种在生长的前 5 天的幼苗生长速度。在幼苗中，MJ 显着增加了 3 日龄下胚轴（带子叶）和黄羽扇豆胚根中异黄酮（包括黄豆苷​​、染料木苷、黄豆苷元和染料木素）的含量。在用 MJ 处理的 3 天龄窄叶羽扇豆幼苗的下胚轴（带有子叶）和胚根中也观察到了这种相关性。在萌发过程中，窄叶羽扇豆种子对外源 MJ 的敏感性高于黄色羽扇豆种子。和染料木黄酮）在 3 日龄的下胚轴（带子叶）和黄羽扇豆胚根中。在用 MJ 处理的 3 天龄窄叶羽扇豆幼苗的下胚轴（带有子叶）和胚根中也观察到了这种相关性。在萌发过程中，窄叶羽扇豆种子对外源 MJ 的敏感性高于黄色羽扇豆种子。和染料木黄酮）在 3 日龄的下胚轴（带子叶）和黄羽扇豆胚根中。在用 MJ 处理的 3 天龄窄叶羽扇豆幼苗的下胚轴（带有子叶）和胚根中也观察到了这种相关性。在萌发过程中，窄叶羽扇豆种子对外源 MJ 的敏感性高于黄色羽扇豆种子。
