Growth variance and character analysis of Cinnamomum camphora seedling from different provenances

In the seedling nursery , 8 characters of 10 Cinnamomum camphora provenances were observed .These provenanoes represented 60 ones tested .The observation data were studied by variance analysis , relationship analysis and progressive analysis .The results showed that there were significant differences for different characters among provenances ;there was extreme significant relationship among 7 characters , including seedling height and ground diameter ;and the ground diameterwas a leading factor which has the tightest relationship with total biomass at seedling stage .
