In order to study the possibility and precision of early selection of picea korainsis,we have measured the stem height of 14-and 20-year-old picea korainsis in different sites and of different types in plantation and also measured the stem height of 3-year-old seedlings in the nursery.According to our calculation, the resultsshow:1. The rank correlation coefficients of stem height, diameter and volume in early vs and later ages are quite significent. All coefficients have reached 0.01 level in T-test. They ...
