TableĀ 2 Product-moment correlation coefficients (r) among wood quality traits measured by acoustics and NIR for the three diallel test series. Correlations are based on full-sib family means. Probability values (H 0:rĀ =Ā 0) are given in parenthesis. Coefficients with a probability ā¤0.05 are not significantly different from zero
