n: number of lumber; MC: moisture content determined by oven-dry method; ARW: annual ring width; AD: air-dry density; SD: standard deviation
**Significant difference among provenances (p < 0.01); *significant difference among provenance (p < 0.05). F values were obtained by one-way ANOVA test in lumber properties
