| 摘 要： | 本文以油菜种子为材料，研究了稀土镧对油菜种子透性和种子活力的影响。在０．０５－２．００ｍｏｌ／Ｌ水平，Ｌａ＾３＋降低种子细胞内的电解质，Ｋ＾＋，Ｃａ＾２＋和Ｎａ＾＋的相对外渗量，并表现为随Ｌａ＾３＋浓度的增加而下降。低于０．１ｍｏｌ／Ｌ降低糖的相对外渗量，高于此浓度糖的相对外渗量升高。

| Abstract: | The experiment was carried out rape seed-"Qing Yu No. 2" and to find out the effects of La(No3)3 on seed permeability and on seed vigor. Results showed that the relative leakage of electrolyte.K .C(2 ) and Na out from seed declined with the increasing of La(No3)3 concentration at the range of 0.01-2.0mool/L. The relative leakage of sugar also declined at lower than 0.1mmol/L but increased above that concentration. Seed vigor was promoted at lower than 0.05mmol/L but inhibited beyond that. |
