Abstract

Abstract: We casually obtained a new variation of Shanhaiguan Poplar (Populus canadensis Moench cv.shanhaiguanensis)in the production process.Its growing rate is higher than the matrilineal trees, and there are obviously diversities in theirmodality.In this test, the abilities of carbon-nitrogen metabolism and biological oxidation were compared with each other.The results indicated that the new variation was stronger than the elder.Especially, the peroxidase isozyme pattern revealed that therewere some differences between the two parties.So it was considered that the newerwas an excellent variation mutating in the process of sexual reproduction.It was provisionally named new shanhaiguan poplar.

Key words: :New shanhaiguan poplar, Modality, Carbon-nitrogen metabolism, Biological oxidation, Peroxidase isozyme
