| 摘 要： | 通过水培苗期毒性试验,研究了9个科23种常见作物幼苗对镉毒害敏感性的差异.结果表明,大部分供试植物在0.1～0.25 mg·L-1镉浓度条件下开始出现表观毒害症状.不同种类作物所表现的毒害症状有较大的差异.作物地上部鲜重对较低浓度镉(0.1～0.5 mg·L-1)胁迫的响应比其他生长性状指标更加敏感和稳定.可作为植物对... |

| Abstract: | 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.... |
