Predictions of the mean number of epicormic shoots produced by trees, representing the interactions season × clone (a) and year × season (b), all pruning intensities combined. Year 2010 corresponds to epicormic branches produced in 2010, 2011_new corresponds to epicormic branches produced in 2011 and 2011_old corresponds to epicormic branches produced in 2010 and 2011 and collected at the end of 2011 growing season. Errors bars are standard errors of the mean. Bars labeled with the same letter are not significantly different (Tukey’s test at P < 0.05)
