摘  要:
以景天科植物的费菜为材料,在模拟屋顶生境下,研究了费菜对干旱、高温、低温逆境胁迫所产生的生理响应。结果表明,在缺水480 d的条件下,费菜的萎蔫系数达3.97;在45℃条件下处理12 h,细胞膜伤害率只有8.5%,但超过47℃时,细胞膜伤害率明显升高;地上部分在-2℃下全部冻死,但地下部分仍可恢复生长。由于费菜具有生长快、抗性强、既可观花也可食用的优点,可以作为华东地区屋顶绿化植物资源对其进行开发利用。

摘  要:
Taking Sedum aizoon L.as the experiment material,the physiological responses of Sedum aizoon L.to drought,heat and cold stress were studied in simulated roof habitat.The results showed that : under dry condition for 480 days,its dwilting coefficient was 3.97;treated at 45 ℃ for 12 h,its membrane injury percentage was only 8.5%,but when the temperature exceeded 47 ℃,its membrane injury percentage was significantly higher;the aerial parts of Sedum aizoon L.all freezed to death at-2 ℃,but the underground part could still recover growth.Sedum aizoon L.has many advantages,such as fast growth,strong resistance;in addition,it is not only ornamental but also edible.So Sedum aizoon L.can be developed and utilized as a kind of plant resources for green roof in east China.
