摘要: 通过水培苗期毒性试验,研究了8个科19种常见蔬菜幼苗在砷胁迫下生长性状敏感性的差异.结果表明,砷对大部分蔬菜的影响存在一个较低浓度(0.1和1.0mg·l-1)的刺激效应和高浓度(10.0mg·l-1以上)的抑制效应.砷对蔬菜地上部生物量的影响普遍较根部明显.蔬菜地上部鲜重对砷胁迫相对敏感,性状稳定,可作为蔬菜对砷敏感性的筛选指标.不同种类蔬菜EC20值的变化范围为0.20—42.87mg·l-1.根据表观症状和EC20对蔬菜砷敏感性分别进行分类,两种分类结果基本一致.黄瓜、红豇豆、苋菜、辣椒、茄子确定为砷敏感蔬菜,可以作为确定土壤和植物中砷的毒害临界值的基础生态受体.

Abstract: Arsenic toxicity to 19 kinds of common vegetables was studied in nutrient solution with different arsenic concentrations.The results showed that there was a stimulating effect at low levels of arsenic application(0.1 or 1.0 mg·l-1)and an inhibitory effect at high level of arsenic application(above 10.0 mg·l-1)for most of the vegetables.The effect of arsenic on shoot biomass was more obvious than that of root.Therefore,shoot fresh weight was selected to be the indicator of vegetable's sensitivity to arsenic since it was the most sensitive to arsenic stress compared to other parameters.EC20 values of different types of vegetables ranged from 0.20 to 42.87 mg·l-1.The arsenic sensitivity of the vegetables are classified into two categories according to the apparent symptoms and EC20 values,respectively.Red bean,amaranth,peppers and eggplant are sensitive vegetables,that can be used as ecological receptors to determine the critical value of arsenic toxicity in soil and plants.
