| 摘 要： | 应用模拟硫酸型酸雨系列对钟萼木科的伯乐树、苏木科的翅英木、楝科的香椿、蝶形花科的刺槐的苗木进行喷洒试验，结果表明：（1）酸雨胁迫对苗木可产生急性伤害，削弱或抑制苗木生长，表现在见性伤斑叶率和脱落率随酸雨PH值下降而递增；株高与根系的生长受到严重削弱。（2）酸雨胁迫可引起游离脯氨酸的变化，其变化因器官不同而异，叶片脯氨酸含量随酸雨PH值下降而大幅度增加，茎的脯氨酸含量增加的幅度较小，而根系脯氨酸含量却随酸雨PH值下降而递减。

| Abstract: | This paper is based on the experiment of spraying wity simulated acid rain of sulfuric acid type upon seedlings of 4 kinds of plantS such as Bretscheid SinenSis HemS,lera instants ChUm, CedrelaSinensis A. fuss and Robinia Pseudoaeacio L.The experiment results Show that: (1)pressure of acid rainhas urgent damage to seedlings and can weaken or restrain the growht of seedlings; (2) pressure Of acidrain can cause the change of floating proline in plants. |
