Abstract:
Five different cabbage varieties including ‘Yuyuan No.1’,‘Yuxin 55’,‘Jinlv 80’,‘Weibai No.8’ and ‘Jinqiu 90’ were selected as materials.Such physiological indexes as chlorophyll a+b content,MDA content，and proline content of the water-cultured seedlings treated under different concentrations of Hg2+ stress and SA-alleviated Hg2+ stress were determined.The results showed that variety ‘Xuxin No.55’ showed the best comprehensive performance in chlorophyll a+b content,variety ‘Yuyuan No.1’ presented the best comprehensive performance in MDA content，while variety ‘Jinqiu No.90’ demonstrated the best comprehensive performance in proline content.The results also indicated that the alleviation effects of 500 mg/L SA are better than that of 100 mg/L SA.
