Abstract: The distribution patterns of shoots, flowers and seeds in the canopy of 14 years old engrafted Ginkgo biloba and their relationships were investigated with stratification method.The result shows that long shoots,short shoots,bearing shoots and flowers uniformly distributed in the central section of canopy.From the top to the bottom, the average age and the divaricating angle of long shoots increase 51.3% of the seeds distributed in 180～320cm layer from the ground.The number of shoots, flowers and seeds in different canopy layers was closely correlated.
