| 摘 要： | 近年来，土壤中可溶性铝增加，对作物生长产生重要影响，本文研究了酸性条件下不同浓度Al^3＋对玉米根芽生长的影响。结果表明，Al对玉米根芽的生长有显著的抑制作用．且随着浓度的升高抑制作用显著加强，但时于根的生长Al^3＋浓度有一个相对促进其生长的浓度（0．5mg／L）；同时，高浓度的Al^3＋能诱导玉米根尖染色体发生多种类型畸变。

| Abstract: | Recent years,the increase of aluminum in soil has great effect on the growth of the crops.The influence of aluminum in different concentration on the growth of Maize root and bud under the acid condition was studied.The result showed that the growth of maize was restrained significantly by the different concentrations of alunminium.But there was a concentration(0.5mg/L) which relatively accelerated the root's growth.As aluminum inducing the various changes have taken place in the chromosome of Maize root top. |
