摘要：
The Castanopsis sclerophylla seed length,seed diameter,seed length× seed diameter,seed length/seed diameter and hundred grain weight from nine areas were studied.The results showed that extremely significant difference were found in seed characters of C.sclerophylla from different areas.The most coefficient of variation is hundred grain weight and the least is seed length/seed diameter.Correlation analysis showed that the seed length and seed diameter had the significant positive correlation with hundred grain weight;seed became bigger and heavier as latitude became lower,the annual average temperature and frost free period become longer;the hundred grain weight had significant positive correlation with rainfall,seed length/seed diameter had significant negative correlation with the rainfall,And clustering analysis showed that phenotypic variation was basicaly continuous variation with the geography,which was consistent with the result of relevant analysis.
