摘要
通过对4种阴生地被植物(庐山景天Sedum baileyi、翠云草Selaginella uncinata、赤车Pellionia radicans、点腺过路黄Lysimachia hemsleyana)干旱胁迫处理后的生长势、游离脯氨酸含量、水分临界饱和亏、叶保水力和根冠比等指标进行观察测定,发现4种植物中庐山景天和翠云草的抗旱性较强,赤车和点腺过路黄的抗旱性较差。
Based on the observation of the growth potential, free proline content, critical water saturation deficiency,leaf water retention and root / shoot ratio of the following four shade ground cover plants： Sedum baileyi, Selaginella uncinata ,Pellionia radicans and Lysimachia hemsleyana, after using drought stress treatment, the drought resistance difference of those four species was found. The better drought resistance plants were Sedum baileyi and Selaginella uncinata ,Pellionia radicans and L ysimachia hemsleyana were the worse species.
