| 摘 要： | 以吉祥草为对照，对六角景天、夏辉景天等景天属植物进行了耐寒性研究。结果表明随低温胁迫增加，质膜透性、叶片空隙率等有不同变化势态。综合各项生理指标，供试品种的耐寒性如下：夏辉景天>苔景天>金银花>佛甲草>玉米石>六角景天>吉祥草（CK）>藓状景天>勘察加景天，这与大田试验观察结果相符。

| Abstract: | This paper researched on cold stress of several sedums in light rooftop greening taking Reineckia carnea and Lonicera japonica as comparison.By screening,the results showed Sedum plants have different adaptability with increase in cold stress.Integrated in physiology,Varieties of cold tolerance as follows：Sedum spurium ＇ Coccineum ＇ Sedum acre Lonicera japonica（CK） Sedum linera Sedum album Sedum sexangulare Reineckia carnea （CK） Sedum polytrichoide Sedum kamtschaticum,and this is consistent with the observation of field experiments. |
