Keywords:: Sedum; high temperature stress; heat resistance; relative humidity

Abstract:: Sedum has been widely applied in Chinese residence roof greening practice，but the categories of Sedum is single，moreover，in practice，it is hard for Sedum to live through summer in high humid south area.To select more roof greening Sedum which could live in high humid south area and provided foundation for the future selection of roof greening Sedum.In contrast of Santolina chamaecyparissus, taking the seven Sedum plants of Sedum reflexum，S.sarmentosum cv，S.lineare ，S.sarmentorsum ‘Variegatum’，S.reflexum cv，S.hispanicum var.minus and S.spurium ‘Voodoo’as test materials，using the index determination method of RWC，electrolyte leakage rate，CAT activity and SOD activity，it was researched on high temperature stress efforts on the relative physiological and biochemical indexes of the test materials，under the condition of different relative humidity，in order to find specical Sedum who had strong capbility to tolerate the high temperature stress.
