摘 要 ：对山黧豆(Lathyrus sativus L.)幼苗整株,喷施一定浓度的Eu3+溶液吸收后,对其相关的生理指标进行测试,结果表明与水喷比较,根中丝氨酸、甘氨酸、丙氨酸、蛋氨酸、亮氨酸、脯氨酸、胱氨酸与对照持平,缬氨酸、酪氨酸、苯丙氨酸、组氨酸略有升高外,其余均低于对照;茎中除精氨酸、脯氨酸、色氨酸略高于对照外,其余均低于对照;叶中除蛋氨酸、色氨酸略高于对照外,其余均低于对照.游离氨基酸总量增加时,茎＞根＞叶,减少时,根＜茎＜叶.蛋白质含量经Eu3+ 处理茎中减少,根和叶中增加;水解酶比活性根＞茎＞叶;Na+、K+-ATPase活力却表现根＞茎＞叶的趋势.表明Eu3+ 对山黧豆生理活性代谢起到一定的调节作用.

Abstract:Lathyrus sativus L. seedlings were fully sprayed with Eu 3+ solution at certain concentrations and their physiological indexes concerned were measured after they had absorbed the solution.The results showed that in the roots of Eu 3+ solution sp
