Abstract: The distribution patterns and relationship of branches,leaves and fruits in the canopy of 6 years old typical engrafted(Dimocarpous longana) were investigated with stratification method.Result shows that the trunk was short and the canopy shaped as the natural semicircle.There were 4 or 5 main long branches in most trees.The long branches uniformly distributed in the canopy.The short branches,fruit-bearing branches and fruits uniformly distributed in the longitudinal rows paralleled the main branch.In the direction being vertical main branch,the short branches,the fruit-bearing branches and fruits uniformly distributed in the central section of canopy.Green leaves and fruits uniformly distributed on canopy surface.The fruits mainly distributed in the canopy from central to 60~150 cm layer of the canopy bottom,accounting for 78.9% of total fruits.The number of branches,fruit-bearing branches and number of fruits as well as the yield in different canopy layers was significantly linearly correlated.
