A Study of Stress Tolerance of a Candidate Plant——Sedum aizoon L.for Green Roof
摘要
Abstract
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.关键词
