Abstract:: External morphology and physiological changes were studied under drought and 45℃ high temperature stress in six Sedum plants.The results showed that with serious level of drought and heat stress，leaves of six Sedum appeared dehydrate and curl,turned yellow,dried off and other symptoms. And different Sedum ?had different degrees at different stages.These expressions reflected their different tolerance to drought and heat stress.Throughout the stress process，soil moisture,relative water content and soluble sugar decreased.Conductivity and MDA contents increased，and different Sedum had distinct rate of increase.According to morphological characteristics and physiological changes，the resistance from highest to lowest to drought and heat in six plants was Sedum spectabile,Yellow S.hybridum‘Immergrunchell’,Early S.hybridum‘Immergrunchell’,Sedum sarmentosum Bunge，Red S.hybridum‘Immergrunchell’,Sedum spurium ‘Coccineum’.
