Abstract

Abstract: By pot experiments，this paper studied the effects of Cu pollution on the biomass, the accumulation of Cu, content of chlorophyll, membrane permeability, the content of catalase (CAT), nitrate reductase (NR) of Brassica campestris ssp. Chinensis in order to supple a scientific and theoretical evidence for vegetable safely planted and diagnosing the heavy metal pollution. The result showed that, the biomass of Brassica campestris ssp was evidently increased under low concentration of Cu. When concentration of Cu is over 100 mg/kg, the biomass of the ground and underground parts are decreased. At the same time the accumulation of Cu in roots was much higher than those in leaves and stems, special in the high Cu condition. Content of chlorophyll and activity of NR first increased, then decreased with increasing concentration of Cu; However, membrane permeability, Content of reducing sugar and activity of CAT showed an opposite trend.
