The experiment is conducted on germination rate,variety of antioxidant enzyme system and protein content in the Radix Isatidis germination polluted by cadmium and lead.The results show Radix Isatidis germination are promoted by 5 mg/L cadmium,while the restraint action is found in the higher concentration treatments.Radix Isatidis germination are restrained under the stress of different lead concentrations,the higher lead concentration,the more restraint action.Root elongation of Radix Isatidis are restrain...
