+Age experiment was conducted with Palmer while variety experiment was on 5-year-old trees. #Value with different superscripted capital letters denotes significant difference using Bonferroni mean separation test (applicable to LAI in age group, where other parameters are all significantly different and TH in variety experiment where other parameters were not statistically different).
