  1. n number of trees, AD air-dry density, OD oven-dry density, RS shrinkage in radial direction per 1% moisture content change, TS shrinkage in tangential direction per 1% moisture content change, TL latewood tracheid length, SD standard deviation. Each value of physical properties and TL in each provenance was calculated by averaging the mean values of five trees. The mean value in each tree was calculated by averaging the values obtained from different radial positions. F-values and p-values were obtained with a one-way ANOVA among provenances.
