摘 要：
为了在干旱地区的园林绿化中,合理选择树种,从叶片解剖结构、水分生理和光合作用3方面对绣球绣线菊(Spiraea blumeiG.Don)和土庄绣线菊(Spiraea pubescensTurcz.)的抗旱性进行研究。试验结果表明,绣球绣线菊的叶片结构比土庄绣线菊更适应干旱环境,在水分胁迫状态下,绣球绣线菊的光合速率、组织含水量等水分生理指标也高于土庄绣线菊。初步认为,绣球绣线菊的抗旱性比土庄绣线菊强。

摘 要：
In order to chooses the appropriate tree for afforesting botanical garden in the drought area,from the leaf anatomical structure,water relations and photosynthesis of two species of Spiraea to studied drought resistance.The results showed that,the leaf anatomical structure of Spiraea blumei G.Don is better than that of Spiraea pubescens Turcz.to adaptation drought,all water parameter of Spiraea blumei G.Don were higher than that of Spiraea pubescens Turcz.,and the photosynthetic rate of Spiraea blumei G.Don.was also higher under drought.It was considered that the Spiraea blumei G.Don has higher drought resistance.
