| 摘 要： | 10 ℃条件下壶瓶碎米荠生长缓慢; 15～25 ℃条件下生长良好, 叶绿素含量和SOD 酶活性较高,MDA 含量较低, POD 酶活性变化不明显, 电解质外渗少; 30 ℃条件下植株叶绿素含量和SOD 酶活性下降,MDA 含量、膜透性和POD 酶活性激增; 35 ℃条件下, 代谢严重紊乱, 鲜样质量下降。研究结果证明, 壶瓶碎米荠不耐高温, 最适生长温度为20 ℃。

| 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 ℃. |
