摘要: 研究酸性条件下不同浓度A13+对豌豆根芽生长的影响.结果表明,Al对豌豆根芽的生长有显著的抑制作用,对豌豆根尖细胞分裂产生危害的初始浓度为1mg·L,Al诱导豌豆根尖染色体发生多种类型畸变,初始浓度为0.5mg·L-1,低浓度下Al对豌豆根芽生长的抑制与植物对Ca、Mg的吸收没有明显的相关性.

Abstract: The influence of aluminum in different concentration on the growth of Pisum sativum soot and bud under the acid condition was studied. The results showed that aluminum remarkably restrained P. sativum root and bud from growing. The initial concentration of aluminum poisoning cell split of P. sativum root top was 1mg·L-1 . As aluminum inducing the various changes have taken place in the chromosome of P. sativum root top, aluminum initial concentration being 0.5mg·L-1 . Between aluminum restraining P. sativum root and bud from growing and this plant absorbing Ca and Mg there is not clearly relation under its less concentration (≤1 5mg·L-1).
