过量铜对苹果树生长及代谢的影响

Effect of excessive copper on growth and metabolism of apple trees

  • 摘要: 通过盆栽试验 ,研究了铜对苹果树生长及代谢的影响。结果表明 ,过量铜会抑制苹果新梢的生长 ,降低叶片中活性铁的含量 ,使叶绿素含量极显著下降 ,叶片中的过氧化氢酶活性也大幅度降低。铜在苹果叶中的积累有一限度 ,小于此限度值 ,叶片中铜的含量随外源铜施加量的增加而增加 ;超过该限度值 ,叶片中铜的含量则几乎不再增加。向土壤中施加钙和铁 ,能降低叶片中铜的含量 ,有减缓过量铜对苹果树生长和代谢毒害的作用

     

    Abstract: Excessive copper in the soil will hinder the extension of young apple branches, decrease the content of active iron and Chlorophyll significantly in the leaves, and decline the activity of catalase in young apple leaves. While the content of copper in the soil is less than a certain degree, the copper content in the leaves increases together with that in the soil, but while more than the degree the content of copper in the leaves hardly rise any longer. Adding Ca and Fe to the soil can decrease copper content in apple leaves, then excessive copper will do less damage to apple trees.
