Abstract

Abstract: The seedling of Cardamine hupingshanensis were treated in chamber of 10 ℃、15 ℃、20 ℃、25 ℃、30 ℃and 35 ℃respectively , the results showed that Cardamine hupingshanensis could grow well with the normal metabolism at 15 - 25 ℃. When the temperature reached 30 ℃, its chlorophyll content and SOD activity decreased quickly , while the MDA content , electrical conductivity and POD activity increased drastically. At 35 ℃, the fresh mass of Cardamine hupingshanensis decreased with the disordered metabolism. The present study indicated that Cardamine hupingshanensis was not tolerant to high temperature and the optimum temperature for the growth was 20 ℃.

Key words: Cardamine hupingshanensis, Temperature, Chlorophyll, Electrical conductivity, POD, MDA, SOD
