Abstract
Objective To know effects of Cd~(2+)on the growth and development of Vicia faba roots and its rule,and to provide certain scientific proofs for culturing new breeds with Cd~(2+) resistance.Methods The effecfs of different concentrations and treat times on Vicia faba roots in color,curved degree,length and cell mitosis were assayed.The root tips were stained with modified carbol fuchsin,then the cell mitosis was observed in microsopy.Results When Cd~(2+) concentration was lower than 10 μmol/L,it could promoted the growth and development of the roots,but the root curve was not obvious.After Cd~(2+) concentration was higher than above-mentioned concebtration,the roots increased in color and curve,but their growth rates and cell mitotic indexes decreased than that of control.Conclusion Cd~(2+) could affect on the growth and development of Vicia faba roots,and were relation to Cd~(2+) concentration and treat time.
