Abstract:
Taking ten cultivars of Chinese cabbage as materials，a hydroponic experiment was carried out to study the impact of Cd stress under 5 μmol/L，to exploring the physiological and biochemical responses and cadmium resistance of different Chinese cabbage cultivars.The results showed that the growth of all the ten cultivars of Chinese cabbage were inhibited under Cd stress，of which ‘Huaguan’ was least affected.The MDA content of ‘Sijiqing’，‘Kangre 605’，‘Huaguani’ and ‘Yunong No.1’ decreased.Except for ‘Sijiqing’ and ‘Huaguan’，the content of ascorbic acid increased in other cultivars，in which ‘Shanghaijimaocai’ increased the most.The chlorophyll content reduced in other cultivars，except for ‘Huaguan’.SOD activity increased in ‘Sijiqing’，‘Huaguan’ and ‘Shanghaijimaocai’.CAT activity decreased in ‘Sijiqing’，‘Pingyou No.1’，‘Huaguan’ and ‘Shanghaijimaocai’.The proline content increased in ‘Sijiqing’，‘Kangre 605’，‘Huaguan’，‘Yuanzhongsiyueman’，‘Shanghaijimaocai’ and ‘Yunong No.1’.The physiological and biochemical response and the tolerance to Cd varied with different cultivars of Chinese cabbage.Among them the tolerance of ‘Sijiqing’，‘Huaguan’ and ‘Shanghaijimaocai ’were greater.
