Abstract:

In order to investigate the reaction and adaptation of Sedum Spectabile Boreau under water stress, taking 1-year-old seedlings of Sedum Spectabile Boreau as test materials, water content of soil, leaves relative water content, SOD activity, POD activity, MDA content and leaves relative water content were studied. Results showed that the water content of soil and leaves relative water content decreased under drought stress; the water content of soil and leaves relative water content increased under water logging stress. under water stress,the relative leakage of electrolytes and MDA content increased，but activities of SOD and POD increased at first but later decreased. Comprehensive analysis showed that Sedum Spectabile Boreau had some resistance on water stress.
