  1. The mean, standard deviation, and coefficients of skewness and kurtosis were calculated for each tree using all measurements and tested for clonal differences. Shown are the mean value for each statistic, and F-values (11 and 12 degrees of freedom) and corresponding P values in tests for clonal differences.
