| 摘 要： | 通过盆栽控盐控水的方法，对君迁子苗期的生理生化反应进行了研究，测定内容包括丙二醛（MDA）含量、叶绿素（Ch1）含量、细胞膜透性（MP）、可溶性糖（ss）浓度、脯氨酸（Pro）含量。结果表明：在一定范围内，与对照相比随着盐分浓度和干旱胁迫的增加，丙二醛含量、可溶性糖浓度、脯氨酸含量都是升高的；叶绿素含量减小；而细胞膜透性则呈不规则的变化。相关性分析显示：可溶性糖与脯氨酸极显著正相关；叶绿素含量和脯氨酸含量存在极显著负相关。

| Abstract: | The potted seedlings of Diospyros lotus L. were studied for their physiological and biochemical response to cross --stress of water and salt by the method of water and salt control. The tested traits are as the followings： contents of MDA, Chl,MP,SS and Pro. The result showed that ：in a certain range,The contents of MDA,SS,Pro were all increased; The contents of Chlorophyll were reduced; but changes of MD are not regular. The result of correlation analysis： the content SS and the content Pro is strong significant; the content Chlorophyll and the content Pro is negative correlation. |
