Abstract

Leaflets of Chinese mahogany were analysed, which sampled from 9 years old provenance forest from late April to middle May. The results showed that the enzyme spectra of peroxidase enzyme of Chinese mahogany consisted of about 30 enzyme bands Which could be divided into A, B, C and D regions. The occurrence frequencies of enzyme bands C21, C31, C32, B31 and B32 were the highest with up to 0.9~1.0 in the experimented population. The frequencies of enzyme bands B11, B22, B45 and C36 were the lowest with below 0.1. In general, the correlation between frequency variations of enzyme bands and provenance geographical positions was small. However, enzyme bands C23, C12, D1 and D3 and provenance latitude reached or approached significant level. The correlation between frequency variations of enzyme bands and tree height, DBH and volume was very small. Only B45 band came up to or closed significant level.
