Table 2 Seed production per pollination for self and outcross pollinations on young (Day 1) and old (Day 4) flowers of Campanula rapunculoides from non-fruit-treated plants of experiment 1. Data are back-transformed least squares means from ANOVA (Table 1) with minus one and plus one standard error in parentheses. Self-incompatibility index is the ratio of self: outcross seeds/capsule
