Figure 1. Reproductive success assessed by seed number (A) and seed weight in mg (B), in function of different pollination treatments.

Pollination treatments were: Spontaneous autogamy (Sa); Facilitated autogamy (Fa); Control group (C); Facilitated xenogamy within varieties (Fxw) and Facilitated xenogamy among varieties (Fxa). Significant statistical differences between treatments (P < 0.001 for seed number and P < 0.01 for seed weight) are marked with different letters, and significant statistical differences between color varieties (orange: black-colored bars; yellow: grey-colored bars) are marked with an asterisk. Bars show the Standard Error (S.E.).
