The preliminary study on juvenile-mature correlation of pinus koraiensis

摘要

Through studying seven analytic trees from two stands of pinus koraiensis artificial forests, the results show that the individual variation coefficient of tree height, dbh and volume decreases with age increasing after age of 25. Age of 25 is the age that difference of individual growth is from acute difference to comparatively stability. The optimum selectiona ge is 25a for pinus koraiensis's artificial forests according to the analysis of juvenile-mature correlation, and early selection effi- ciency.
