| 摘 要： | 在特定污染条件下，植物叶脯氨酸含量与K+渗出量(％)呈负相关变化，并因树种和叶片成熟度而异、脯氨酸含量为成叶>老叶，K+渗出量则是老叶>成叶，外施脯氨酸对植物亚硫酸伤害具有一定的防护作用。

| Abstract: | Under specified condition of pollution, the content of endogenous proline was negatively correlative to the K efflux in leaves. The relation between the proline content and the K efflux may change among species and maturity of leaves. In general, the content of proline in the mature leaves was higher than that in the old leaves and the K efflux of the old leaves was higher than that of mature leaves, Spraying proline had a protective effect against sulfurous acid insult. |
