摘　　要：对林下微生境和全光照下的5个草坪草品种叶绿素含量及叶绿素a/b值进行了对比试验研究。结果表明:林下微生境使得草坪草叶绿素含量及叶绿素a/b值均发生规律性的变化,叶绿素含量林下的明显高于全光照下的,而叶绿素a/b值则相反。根据这两个指标进行分析,普通、欧宝和优异对林下微生境的适应性较强,派尼和高羊茅猎狗5适应性中等,午夜较差。Comparison test on chlorophyll content and chlorophyll a/b value of 5 lawn species under tree and open air resulted that chlorophyll content and chlorophyll a/b value of lawn under tree changed regularly, chlorophyll content of lawn under tree was evidently higher than that in open air, but chlorophyll a/b value was on the contrary.

关 键 词：草坪草 叶绿素含量 林下微生境 品种 适应性 环境因子 光照
