Abstract:

Taking two vaieties of Brassica pekinensis Rupr.‘Beijing Tieqiu Xiaobao’ and‘Jinqing 75’as materials，by soil test，the growth，cadmium(Cd) accumulation and its subcellular distribution in two vaieties of?Brassica pekinensis Rupr.were studied.The results showed that the increasing of Cd concentration inhibited the growth of ?B.pekinensis，and compared with the control，the total dry weights of variety ‘Beijing Tieqiu Xiaobao’ and ‘Jinqing 75’ were reduced by 11.3% and 40.12% at 5 mg/kg Cd，respectively.Comparatively，the inhibited degree of Cd on variety ‘Beijing Tieqiu Xiaobao’ was lower than variety of ‘Jinqing 75’.The absorbed Cd was mainly accumulated in roots of the two varieties of B.pekinensis.Absorbed dose was increased with the increasing of Cd application rate.Moreover，the total Cd accumulation in vatiety of ‘Beijing Tieqiu Xiaobao’ were 52% and 47% higher than variety of ‘Jinqing 75’，respectively，under 1.0 and 5.0 mg/kg Cd.The distribution of Cd was more in roots of ‘Beijing Tieqiu Xiaobao’.On the whole，Cd accumulation in variety of ‘Beijing Tieqiu Xiaobao’ was higher，the distribution rate in cell organ was lower and the inhibited degree in growth was lower than those in variety of ‘Jinqing 75’.Therefore，the variety of ‘Beijing Tieqiu Xiaobao’ had stronger utilization potentiality in phytoremediation of soil Cd pollution.
