A pot experiment was carried out to evaluate the effects of heavy metals on biomass, chlorophyll, and antioxidative enzyme activities of eight vegetables grown in a saline soil. The heavy metal accumulation in vegetables was also investigated. Results show that biomass and chlorophyll content of crops decreased with the increase of heavy metal concentration while peroxidase activity increased at low concentration and decreased at high concentration. The total translocation factor values in the eight vegetables are in order: water spinach>Chinese kale>pakchoi>edible amaranth>leaf mustard>Chinese flowering cabbage>green capsicum>tomato. Tomato, which is the most salt tolerant crop of the eight vegetables, also is the most heavy metals resistant studied in terms of growth, peroxidase activity and heavy metals translocation. Salt tolerant fruit vegetables such as tomato might be potential crops for the safe use of saline soils polluted with heavy metals.
进行了一项盆栽实验，以评估重金属对在盐渍土壤中生长的 8 种蔬菜的生物量、叶绿素和抗氧化酶活性的影响。还研究了蔬菜中重金属的积累情况。结果表明，随着重金属浓度的增加，作物的生物量和叶绿素含量降低，而过氧化物酶活性在低浓度时增加，在高浓度时降低。8 种蔬菜的总迁移系数值依次为：空心菜>芥蓝>白菜>苋菜>芥菜>白菜花>青椒>番茄。番茄是 8 种蔬菜中最耐盐的作物，在生长、过氧化物酶活性和重金属迁移方面也是研究中最耐重金属的作物。番茄等耐盐水果蔬菜可能是安全利用受重金属污染的盐渍土壤的潜在作物。
