在重金属暴露后，在绿藻小球藻中观察到抗氧化酶（过氧化氢酶、抗坏血酸pet氧化酶、谷胱甘肽还原酶、超氧化物歧化酶）活性和总抗坏血酸和还原性谷胱甘肽水平的浓度依赖性增加。它按以下顺序排列：铜>铅>镉。此外，油菜素内酯还能激活重金属处理的芥蓝培养物的酶系统和非酶系统。油菜素内酯在植物对重金属胁迫的响应中起着重要作用。对受重金属污染的寻常草有抗应激作用。(C) 2009 Elsevier B.V.版权所有
A concentration-dependent increase in activity of antioxidant enzymes (catalase, ascorbate pet oxidase, glutathione reductase, ssuperoxide dismutase) and the level of total ascorbate and reduced glutathione have been observed in the green alga Chlorella vulgaris following heavy metals exposure. It was arranged ill the following order: copper > lead > cadmium. It was also found that brassinolide activated enzymatic and non-enzymatic system in C. vulgaris Cultures treated with heavy metals. Brassinolide plays an important role in plant responding to heavy metals' stress. It has an anti-stress effect on C. vulgaris contaminated by heavy metals. (C) 2009 Elsevier B.V. All rights reserved.
