Based on stepwise regression and path analysis,the relationship between the tree composition and yield of Camellia oleifera was examined.It was found that four factors of tree composition including the crown width,the tree height,the clear bole height and the number of scaffold branches have significant impact on yield and the number of scaffold branches has closest relationship with the yield per plant.The multiple linear regression equation and the path coefficient between the four factors and yield per plant were obtained.Therefore,it is the key measure,for increasing C.oleifera yield to im...
