Abstract
A pot experiment was conducted to study the effects of soil and foliar application of Zn SO4 with different dosages on growth and concentrations of cadmium( Cd) and other trace elements in a low cadmium accumulating cultivar of Brassica chinensis. The regulating mechanism was elucidated through analyses of Cd uptake and transport in the low cadmium accumulating cultivar and soil available Cd concentrations. Results show that soil zinc( Zn) application significantly increased shoot biomass of the tested low cadmium accumulating cultivar,with a maximal increase of 71. 4% compared to the control. Meanwhile,foliar Zn treatments had insignificant effect on shoot biomass of the low cadmium accumulating cultivar. Soil and foliar Zn applications significantly decreased shoot Cd concentrations of the low cadmium accumulating cultivar,with a maximal reduction of 41. 4% compared to the control. Although the difference between the Zn dosages of soil application and foliar spray were 8 to 10 folds,the reduction of shoot Cd concentration due to foliar Zn application was not significantly different from that due to soil Zn application. Soil Zn application increased significantly shoots copper and ferrum concentrations of the low cadmium accumulating cultivar,and foliar Zn application had insignificant effect on shoots copper and ferrum concentrations. However,soil and foliar Zn applications decreased significantly shoots manganese concentrations of the low cadmium accumulating cultivar. Soil Zn application increased the soil available Zn concentrations and had insignificant effect on the soil available Cd concentrations. Soil andfoliar Zn applications reduced significantly Cd net uptake via roots and Cd translocation factor of Brassica chinensis. The shoot Cd concentration was positively correlated with Cd net uptake via roots,and not significantly correlated with Cd translocation factor,which indicated that inhibition of Cd uptake by root resulted in decrease in shoot Cd concentration of Brassica chinensis under soil and foliar Zn treatments. In summary,foliar spray of Zn SO4 is suitable for safe production of the low cadmium accumulating cultivar of Brassica chinensis in Cd polluted soils.
