[目的]探求干旱胁迫和复水条件下红椿盆栽幼苗叶片生理特性的整体相关性,为深入研究红椿的抗旱性奠定基础.[方法]在人工遮雨棚中对2年生红椿盆栽幼苗进行干旱胁迫及复水试验,测定叶片相对含水量、相对电导率、叶绿素含量、SOD活性、POD活性、MDA含量、游离脯氨酸含量及可溶性蛋白含量8个叶片生理指标,并运用典型相关法对未干旱(干旱胁迫前)、干旱胁迫及复水条件下3组指标两两之间的整体相关性进行分析.[结果](1)干旱胁迫前与干旱胁迫条件下,红椿盆栽幼苗叶片生理特性之间存在显著相关关系,干旱胁迫前及干旱胁迫下红椿幼苗生理响应典型相关分析的第1对典型变量(U1,V1)的相关系数达到0.996 5,叶片...

【Objective】The study discovered the correlation of leaf physiological characteristics of Too-na cilliate Roem.potted seedlings among drought stress and rewatering to build knowledge foundation for investigating drought tolerance of Toona cilliate Roem.【Method】The drought stress and rewatering experiment was conducted in artificial-rain-shelter with 2years old Toona cilliate Roem.potted seedlings.Eight leaf physiological indicators including leaf relative water content,leaf relative conductivity,chlorophyll content,SOD activity,POD activity,...
