摘要
为了揭示植物抗旱性能,选择5种园林植物并对其叶绿素含量、质膜透性和相对含水量的季节变化进行分析,结果表明:叶绿素含量的变化反映了植物抗旱性大小为:桃树>石楠>红叶李>三角枫>小叶黄杨;相对电导率和含水量的变化反映了植物抗旱性能强弱为:桃树>石楠>小叶黄杨>红叶李>三角枫;综合评价植物抗旱性能的大小顺序为:桃树>石楠>小叶黄杨>红叶李>三角枫。
In order to reveal the drought resistant capacity,5 landscape plants were selected,and their chlorophyll content,plasmalemma permeability and lative water content by seasonal variation were analyzed.The rults showed that their drought resistant abilities by the change of chlorophyll content were in order of Prunus penica ＞ Photinia serrulam ＞ Prunus ceraifera ＞ Acer bugerianuan ＞ Buxus sinica,and their drought resistant capacities by the change of relative conductance and water content were in order of Prunus persica ＞ Photinia semlata ＞ Buxus sinica ＞ Prunus cemifem ＞ Acer buergerianum.Their drought resistm sequence by comprehensive evaluation was followed：Prunuspenica ＞Phonia semlam ＞ Buxussinica＞ Prunusceraifera＞ Acerbuergerianum.
