↵1 Average number of sprouts produced for each treatment group over time where the standard error of the mean is in parentheses.
↵2 Average caliper of sprouts produced for each treatment group over time where the standard error of the mean is in parentheses.
↵3 Different letters indicate significant differences between pruning cut severity treatment means for each growing season independently.
↵4 Pruning cut severity relative to the basal diameter of the stem being pruned.
