Fig. 1From: Production and role of epicormic shoots in pruned hybrid poplar: effects of clone, pruning season and intensityPredictions for the mean number (a) and biomass (b) of epicormic shoots produced for each pruning intensity (1/3 or 2/3 crown length), all clones, seasons, and growing seasons combined. Error bars are standard errors of the mean. Bars labeled with the same letter within a graph are not significantly different (Tukey’s test at P < 0.05)Back to article page
