三种彩色树对水分胁迫的生理响应

The physiological response of three color trees under water stress condition

以紫叶风箱果、金叶榆、密枝红叶李三种彩色树2 a生植株为试验材料,测定水分胁迫下叶片可溶性糖含量、丙二醛含量、叶片含水量以及生长情况等生理指标,结果表明:金叶榆具有较强的耐水浸能力,紫叶风箱果和密枝红叶李耐水浸能力较弱。紫叶风箱果的抗旱性略好于金叶榆和密枝红叶李,但总体来看,三种彩色树抗旱性差别不大。

The two years three color trees Umus punila cv.jinye, Prunus cerasifera var.atropurpured Russia and Physo-carpus opulifolius‘Summer Wine’ were chosen as experiment material.The leaf soluble sugar content, MDA content, leaf water content and growth condition was measured under water stress condition.The result showed that Umus punila cv. jinye had stronger water resistant capacity.The water resistant capacity of Physocarpus opulifolius＇Summer Wine＇and Prunus cerasifera var.atropurpured Russia were weaker.The drought resistance of Physocarpus opulifolius＇Summer Wine＇was better than Umus punila cv.jinye and Prunus cerasifera var.atropurpured Russia.The drought resistance difference of three color trees was little overall.
