摘要
采用座标综合评定法，Ｒ型因子分析和数量化模型Ⅲ等方法对水培和盆栽等３次试验所观测的各项耐盐指标值进行了综合的评定和分析。综合评定结果把供试的１０个无性系划分为３种耐盐类型：（１）耐盐能力强类型。包括９５，１２１和８９无性系，能忍受０．２％～０．３％的土壤含盐量，（２）耐盐能力中等类型，包括１０５，１０６和３５１等３个无性系，能在０．１％～０．２％含盐量的土壤中生长，（３）耐盐能力差类型。包括１３８８．１３８１，１０３和１１７等４个无性系，只能在熟化的低产农田正常生长。
ased on data from tests hydroponic and potted plantation
with soil by coordinate integrative assessment,principal component analysis,and quantitative
theory Ⅲ,author classified ten new poplar dones into three sorts of tolerance to
salt-stress,Type l clones(l21 , 69 and 95)weie resistant to salt-stresstsalinity between 0.2%and
0.3%),Type 2 clones (106, 35l and105)were moderately tolerant to salt-stress (salinity
between0.1%～0.2%). Type 3 clones(103, 117, 1388 and l381)were intolerant to
salt-stree(salinity of less than0.1%) :.
