Effects of Competition on the Vertical Distribution of Foliage Biomass within the Crowns of Planted Korean Pine Trees in Northeast China

The characteristics and distribution of foliage biomass are important aspects the crown structures trees. In this study, we developed a model at branch level annual shoot (i.e., all branches on an increment main tree bole) using sample 51 Korean pine trees that were destructively sampled in Liaoning Province, northeast China. A variety independent variables, including branches, trees, forest competition, used as explanatory variables development. Our results indicated increased with increasing relative distance from tip into crown. peak shifted to age. power function, diameter competition showed excellent performance modeling level. final model, which included diameter, base for density, best performance. advantageous growth ability also had larger amount biomass.
