| 摘 要： | 通过水培实验研究了在1,10和30 mg/L浓度下,金霉素(chlortetracycline, CTC)和其代谢物差向金霉素(4-epi-chlortetracycline, ECTC)胁迫对小白菜种子的萌发、幼苗的早期生长、幼苗中抗氧化酶系统活性的变化以及CTC和ECTC积累进行了研究。结果表明,根长较其他指标对CTC和ECTC生态毒性实验更为敏感,小白菜体内SOD、POD和CAT活性被CTC诱导,活性逐渐升高,其中SOD、POD活性均高于对照,低浓度ECTC促进了SOD、POD和CAT活性的升高,高浓度时POD和CAT活性被抑制,且随浓度升高,抑制作用加强,表明小白菜抗CTC胁迫的能力强于ECTC。CTC和ECTC能在小白菜地上部分积累,处理浓度越高,吸收和积累量越多,其中CTC被积累作用强于ECTC。 |

| Abstract: | The effects of different concentrations of chlortetracycline(CTC) and 4-epi-chlortetracycline(ECTC)(1,10,30 mg/L) on seed germination,growth,antioxidant enzyme systems,CTC and ECTC accumulation in pakchoi(Brassica campestris ssp.chinensis) seedlings were investigated using a water culture method.The results indicated that root elongation could be recommended as a sensitivity indicator to assess eco-toxicity of CTC and ECTC compared with other targets.The activities of SOD,POD and CAT of pakchoi were enhance... |
