Keyword:  盐生植物抗盐性生理指标;
Abstract: 研究对几种盐生植物进行了相关抗盐生理指标测定,抗盐生理指标测定结果表明:盐生植物组的功能叶中MDA含量平均值高于非盐生植物对照组,而膜透性平均值低于对照组;盐生植物组Cl-离子含量平均值高于对照组,可溶性糖含量平均值低于对照组,脯氨酸含量在所测3种渗透调节剂中所占比例最高,而且盐生植物组平均值高于对照组;无机渗透剂与有机渗透剂之间似有互补关系;Cl-离子含量与肉质性存在一定正相关;盐生植物组和对照组中叶绿素含量相近,并对不同生理指标的意义作了初步探讨.研究认为,膜透性、MDA含量以及渗透调节物质的种类和含量对植物抗盐性具有比较明确的指示意义.
