Китайский. ［目的］探讨小麦 (Triticum aestivum L.)叶绿素含量与抗旱性的关系。［方法］以旱地和水地小麦品种为供试材料，在不同灌水条件下对其叶绿素含量、离体叶片失水速率（RWL）及组织含水量(OWC)进行研究。［结果］旱地品种叶绿素含量、RWL及WOC低于水地品种，旱胁迫下旱地品种叶绿素含量、RWL和OWC降低值小于水地品种；叶绿素含量与RWL呈极显著正相关，与OWC呈显著正相关。［结论］小麦叶绿素含量与抗旱性关系密切，可以为小麦抗旱节水性鉴定提供参考。

Under drought stress, chlorophyll content and RWL had a great significant positive correlation, and had just a significant positive correlation with OWC. ［Conclusion］ The study has been found that wheat chlorophyll content has a close relationship with drought resistance, which can provide reference for identification concerned with drought resistance and water saving._
