【Abstract】 In this paper, relationship between fruit-bearing and growth was analyzed by gray correlativity with the indicators of fruit-bearing quantities and growth of each clone in seed orchard of Pinus koraiensis clones as the basis. The results indicate that 3 factors correlated with fruit-bearing quantities were in the following order: DBH, diameter of branch stem and height. Thus it concludes that tree’s vigorous growth was the requisite for fruit-bearing.更多还原
