Abstract
本文以沙拐枣属5种植物为研究材料,采用干旱胁迫模拟实验,研究沙拐枣属植物抗旱特征及其能力综合评价。结果表明:在干旱胁迫条件下,沙拐枣属植物生长量指标都有明显的降低趋势;除无叶沙拐枣和红果沙拐枣外,叶绿素含量和光合参数有降低的趋势;除淡枝沙拐枣外,保护酶系统的SOD、POD的活性呈增高趋势;丙二醛含量和叶绿素荧光值也呈增高的趋势。灰色关联度分析可知:叶绿素荧光和生长量等作为沙拐枣属植物抗旱性鉴定的初级指标,并结合饱和含水量、POD、鲜重、干重、Chl和SOD等指标综合鉴定。5种植物抗旱性强弱的顺序依次为:淡枝沙拐枣 > 乔木状沙拐枣 > 红叶沙拐枣 > 无叶沙拐枣 > 头状沙拐枣。
