Abstract

In order to understand the physiological and biochemical responses of Hydrilla verticillata under heavy metal stress, single and combined Cu or Zn were used for stress cultivation. The results showed that the activities of SOD, POD and MDA in the first treatment group (Cu<0.2 mg/L, Zn<1.6 mg/L, Cu+Zn<0.1 mg/L + 0.8mg/L) were slightly lower than those in a blank control group. SOD, POD and MDA increased significantly with the increase of heavy metal concentration within 7 days. From the 7th day to the 21st day of culture, they increased first, then decreased. The change range of enzyme activity was the largest under combined stress. The inhibitory effects of heavy metals on H. Verticillata were: combined stress > Cu stress > Zn stress.
