摘要
对毛白杨双杂交无性系ｌａ生苗木叶片解剖构造、离体叶片失水率、组织细胞质膜透性进行了测定比较。用这３项指标对各无性系叶片保水力进行了综合评判，并对各指标进行了评价。
The leaf dissect constructions,rates of leaf water losing and membranepemeabilities of 35 hybrid white poplar clones were measured and compared.The leaf waterholding abilities of the clones were comprehensively judged with the three indexes.And theindexes were appraised.
