Different Sensitivity of 23 Common Crop Species to Cadmium Toxicity
23种常见作物对镉毒害的敏感性差异

Cadmium toxicity to 23 kinds of commonly cultivated crops of 9 families was studied by solution culture with different cadmium concentrations.Most of the studied crop seedlings showed cadmium toxicity symptoms with 0.1-0.25 mg.L-1.The toxic effects of cadmium on the crops were quite different.The effect of Cd on shoot biomass was more obvious and stable than the other parameters at low Cd concentrations(0.1-0.5 mg.L-1),Therefore,shoot fresh weight was selected to be the indicator of plant sensitivity to Cd....
