摘　　要：The isozymes of peroxidase (POD) and superoxide dismutase (SOD) in leaves of Taxodium mucronatum Tenore, T. ’Zhongshansha 302’ and four strains of their hybrids were analysed. The result showed that SOD isozyme expressed only in May, POD isozyme had a certain difference among 6 samples in May and July, but notable differences existed in September, when POD isozyme of every hybrids had three bands from the paternal form, 3-6 bands respectively from the maternal form and a few new bands. It was suggested that the genetic characters of POD isozyme of both parents were stably inherited to their hybrids,but some variations occured in those hybrids and POD isozyme was a suitable enzyme system to distinguish the various hybrids.The isozymes of peroxidase (POD) and superoxide dismutase (SOD) in leaves of Taxodium mucronatum Tenore, T.
