| 摘 要： | 以6个毛白杨双杂交无性系为材料，测定了超氧化物歧化酶(SOD)活性，过氧化物酶(POD)活性、原生质膜透性等指标在冬季的变化。结果表明，各无性系SOD活性冬季变化可分为两种类型，其它指标变化模式基本一致，但各无性系间指标值差异显著；各无性系原生质膜透性均在12月达到最小，抗寒能力最强；以各指标值进行抗寒性综合评定，无性系间差异明显，各指标与综合评定结果间均存在显著相关。

| Abstract: | The variations of SOD activity, POD activity, permeability in winter with six hybrid clones of Populus tomentosa were investigated. The results show that the SOD activity variation of the clones can be divided into two types and the variation patterns of other indexes were similar. The difference in the indexes value among the clones was significantly different, in December the permeabilities in all clones examined were lowest and the ability of cold resistance was highest. The results of comprehensive evaluation according to the indexes also show significant differences among the clones. There were significant correlation between the indexes and the result of comprehensive comparison. |
