摘要: 用主分量分析法对11种沙拐枣的水势, 相对含水率, 蒸腾强度、束缚水/自由水、体积/表面积。茎中维管束数目和表皮气孔密度7个指标综合分析, 得出11种沙拐枣抗旱性由强到弱的顺序为; 红皮沙拐枣→头状沙拐枣→白皮沙拐枣→心形沙拐枣→东缰沙拐枣→小果沙拐枣→膜果沙拐枣→蒙古沙拐枣→乔木状沙拐枣→精河沙拐枣→昆仑沙拐枣。
Abstract: Stomatal density, number of vascular bundle, relative water content, water potential, trans piration rate, bound water content-free water content ratio, and volume-surface area ratio of stem were measured to evalute drought resistance of 11 species using principal component analysis method.The orders of 11 species(from strong drought resistance to weak drought resistance) are, C.rubicundum-C.capult-medusae-C.leucocladum-C.cond atum-C.K1ementzii-C.Pumilum-C.junceum-C.mongolicum-C.anborescens-C.ebi-nuricum-C.roorowgkli.
