| 摘 要： | 采用水培试验,研究了镉对锌、硼、锰、钼、铜和铁元素在水稻幼苗中累积的影响。结果表明,不同浓度镉处理,能不同程度地提高水稻根、叶鞘和叶片中锌、硼含量,降低其中的铜含量;提高水稻叶片中锰和钼含量,降低根中锰和钼含量;提高水稻根中的铁含量,而降低叶鞘和叶片中铁含量。镉对锌、硼、锰、钼、铜和铁元素累积的影响是水稻幼苗缓解镉毒害的一种反应。

| Abstract: | The effect of cadmium on the accumulation of zinc,boron,manganese,molybdenum,copper,and iron in rice seedlings was studied by hydroponic experiment.The results showed that cadmium treatment increased the concentration of zinc and boron,but reduced copper concentration in leaves,leaf sheaths and roots of rice seedlings.It also increased the concentration of manganese and molybdenum in leaves,while reduced them in roots of rice seedlings;increased iron concentration in roots,while reduced it in leaves and leaf sheaths.It was proposed that the effect of cadmium on the accumulation of zinc,boron,manganese,molybdenum,copper and iron in rice seedlings be a response to alleviating cadmium toxicity. |
