[i] Note: Values obtained through the best GLMM (generalized linear mixed model), using a criterion of lower AIC (Akaike information criterion), for the selected estimators to compare the effect of different types of entomophilous pollination. Fisher's LSD (least significant difference) test was used to represent the differences between treatments. The letter “A” denotes the highest average value. Means with a common letter are not significantly different (p > 0.05). The presented values include the temporal and inter-plant variability, being expressed as mean (±standard error).
