Table 3 P-values of the F ratios from ANOVA for the effects of pruning time, fraction of plants pruned and their interaction on average pineapple fruit quality attributes and variation in quality (CV) in two experiments for data based on all plants and on plants with slips only

From: Selective pruning in pineapple plants as means to reduce heterogeneity in fruit quality
