Abstract

Analysis on physiological and biochemical indexes of 3 species of perennial flowers introduced to Shigatse area.

Abstract

The changes of 3 species of perennial flowers (Hosta plantaginea, Sedum spurium 'Coccineum' and Hemerocallis fulva) introduced from Harbin to Shigatse were compared in terms of their leaves' chlorophyll content, soluble protein content, soluble reducing sugar content, and superoxide dismutase (SOD) activity. The results showed that under the adverse environment, the chlorophyll content was relatively stable, but the soluble protein content, soluble reducing sugar content and SOD activity increased to some extent with time. The increase of the SOD activity improved the capacity to eliminate the active oxygen in the cells and played a protective role for the membrane system.
