上海地区轻型屋顶绿化景天属植物的耐湿热性研究

为筛选出适应上海地区轻型屋顶绿化应用的免维护植物材料,以金银花、吉祥草为对照,对轻型屋顶绿化植物六角景天、夏辉景天等景天属植物的形态指标、生理指标进行了耐湿热性研究。结果表明,随湿热胁迫增加,其叶片相对含水量、叶表面温度、质膜透性、过氧化氢酶活性等有不同变化态势。综合各项生理指标,供试品种的耐湿热能力大小为金银花>吉祥草>勘察加景天>佛甲草>藓状景天>夏辉景天>玉米石>六角景天>苔景天,这与大田试验观察结果相符。

Research on Moisture Thermo Resistant of Sedum in Light Rooftop Greening in Shanghai

In order to select suitable plant materials,increase roof greening application forms,creat lower carbon city in Shanghai region,the paper researched the moisture thermo resistant of several sedums in light rooftop greening taking Lonicera japonica and Reineckia carnea as CK.The results showed that Sedum plants had different adaptability to moisture thermo.The ability of the moisture thermo resistant was as follows: Lonicera japonica>Reineckia carnea>Sedum kamtschaticum>Sedum linera>Sedum polytrichoides>Sedum spurium 'Coccineum'>Sedum album>Sedum sexangulare>Sedum acre,and this is consistent with the observation of field experiments.
