The aim is to understand the cadmium tolerance of ramie cultivars with different fineness.Ramie cutting seedlings (60 days) with the same growth condition were transplanted to soils treated with 0,25,75,150 mg/kg Cd stress,respectively.The Cd tolerance experiment lasted for 1 year.The results showed that,under 25 mg/kg Cd stress,the comprehensive tolerance indexes of the 12 ramie cuhivars ranged from 0.80 to 1.18,'Zhongzhu 1#'(medium fineness) had the best Cd tolerance,while'Dazhu Huangbaima'(low fineness) had the worst Cd tolerance.Under 75 mg/kg Cd stress,the comprehensive tolerance indexes ...
