摘　　要：测定了杏树17个品种在7月份和9月份的叶绿素含量、比叶重变化和叶绿素a/b比值,结果表明,9月份大部分品种的叶绿素含量下降,比叶重和叶绿素a/b比值增加。3个指标的数值变化与品种的败育率之间没有关系。In the experiment, seventeen apricot varieties were selected and the contents of the chlorophyll, the variation of SLW and the value of chlorophyll a/b were tnenstmated in July and in September . The results showed： in September the contents of the chlorophyll was decreased; the SLW and the value of chlorophyll a/b were increased. No relationship was found between the index of leaf and pistil sterile percentage.
