| 摘 要： | 研究了不同 p H值 (p H5.6、4 .5、3.5、3.0、2 .5)的模拟酸雨对不同时期荔枝叶片 (红色嫩叶、成长叶片及老叶 )的影响 .结果表明 :成长叶片的抗酸能力最强 ;叶片可溶性糖、K+、Ca2 +、Mg2 +的渗出量随酸雨的 p H值的下降而增加 ,说明细胞的膜透性增加 .K+ 的渗出量可作为酸雨伤害荔枝叶片的主要评价指标 .

| Abstract: | Effects of simulated acid rain with various pH values on leaf in different stages of litchi( Litchi chinensis Sonn.) were studied. The results were as follows: the resistance of growing leaf to acid was the strongest; the leakage amount of soluble sugar, K +, Ca 2+ and Mg 2+ of litchi increased with the decline of the pH value of simulated acid rain, and the cell membrane permeability increased. The leakage amount of K + could be regarded as an important index for evaluating the injury of acid rain to litchi leaf. |
