Study on Drought Resistance of Sedum in Extensive Green Roofs
Green roof is one of the effective measures to improve ecological environment problems, and to keep the citys sustainable development. Species selection restricted green roof rapid development. This study we treated different plants with water stress. Their morphological characteristics, visual quality, water retention capability, relative water content, electrolyte leakage as well as CAT and POD activity were measured. Results indicated that: the species have different response in different water stress. With stress intensifies, water retention capability decrease electrolyte leakage increase. S. acre, S. polytrichoides Hemsl and Lonicera japonica reached permanent wilting point in 2 weeks of water stress. S. acre were dead more than 80％, S. polytrichoides Hemsl more than 60％ in 3 weeks of water stress. The order of water resistance from high to low as: S. linera > S. sexangulare >S. spurium Coccineum > S. album> S. kamtschaticum> Reineckia carnea > S. polytrichoides Hemsl> S. acre > Lonicera japonica.
