摘要
本文以束缚水/自由水比值、保水能力、相对含水量、水势、蒸腾速率和chl a/b为指标,应用主分量分析法,进行耐旱性综合评价。结果表明,其耐旱性由强到弱的顺序为:梭梭——白梭梭——多枝柽柳——头状沙拐枣——红果沙拐枣——箭杆杨。
The drought tolerance of xerophytes were comprehensively studied by principal component analysis method depending on bound water/free water ratio, water holding capacity, relative water content, water potential, transpiratory rate and Ch1 a/b. The results indicated the drought tolerance order of plants from strongness to weakness was: H. ammondendron——H. persicum——T. ramosissimia——C. capur—medusae——C. rubicundum——P. nigra.
