稀土元素铽对蚕豆幼苗生长势的影响

Rare-earth element terbium to broad bean root point fresh growingtrend influence

试验以蚕豆为材料，研究了铽对种子生长势的影响。试验结果显示：低浓度下（3～6μg／mL）硝酸铽处理的蚕豆根、芽重量逐次增大，（12～48μg／mL）硝酸铽处理的蚕豆根、芽重量逐次减小。说明蚕豆种子的最佳浸种浓度为6μg／mL。

This experiment take the broad bean as a material, has studied theterbium to the seed fresh growing trend influence. The seed freshgrowing trend test result showed that, Under the low density （3 - 6μg/mL） the terbium nitrate processing broad bean root, the bud weightgradually increase, （ 12 - 48μg/mL） the terbium nitrate processingbroad bean root, the bud weight gradually reduce. Explained the broadbean seed best soaks seeds the density is 6μg/mL.
