Least square means (±standard error) of dry matter (g·plant−1) in different plant organs (stem, leaves and inflorescences) and locations (total, main axis and side shoots) for each pruning technique (PT). For each plant organ and location, means with at least one identical letter are not significantly different from each other according to Fisher´s LSD test with α = 0.05. Pruning techniques (C—control; L—lollipop; T—topping). Note that p-values correspond to F-test within an ANOVA.
