  1. Each value is the treatment mean with standard error in parentheses for 12 trees. The Tukey HSD test was performed between treatments. Means followed by the same letter are not significantly different at P < 0.05. Significance of treatment effects is shown as F value followed by P category: ***significant at P < 0.001.
