| 摘 要： | 以水稻幼苗为材料研究了铝的植物毒性。将不同浓度的 AlCl 加入培养液,对幼苗处理30天。10ppm 以上的铝明显抑制水稻幼苗根和地上部分的生长。5.0ppm 以上铝可引起毒害症状。铝对根的毒害作用大于对地上部分的作用。铝主要积累在根部,少部分转移到地上部分。5.0ppm 以上的铝对叶绿体 Hill 反应和光合磷酸化作用以及根线粒体呼吸和氧化磷酸化作用均有较明显抑制作用。钙对铝的此种抑制作用有一定拮抗作用。

| Abstract: | The phytotoxicity of aluminium on rice seediings was studied.Putting different concentra- tions of AlCl_3 in culture solution and maintaining for 30 days were made as the treatments of Al to rice seedlings.More than 1.0 ppm of Al obviously inhibited the growth of both roots and shoots.The most of Al was accumulated in roots and the minority of Al was transported to shoots.Aluminium inhibited the Hill reaction and photophosphorylation of chloroplasts as well as the respiration and oxidative phosphorylation of mitochondria in roots.Calcium was an antagonist to aluminium in effects on above functions of rice seedling. |
