| Treatment I: controls | ||||
| Non-pollinated, complete emasculation | 0 | 0 | ||
| Non-pollinated, no emasculation | 3 | 13 | ||
| Non-pollinated, only lateral stamens remained | 0 | 1 | ||
| Non-pollinated, only central stamen remained | 0 | 14 | ||
| Non-pollinated, only staminodes remained | 0 | 0 | ||
| Unopened flower | 1 | 8 | ||
| Treatment II: same-species pollination | ||||
| Lateral stamen (self-pollinated) | 9 | 19 | ||
| Central stamen (self-pollinated) | 19 | 22 | ||
| Staminode (self-pollinated) | 0 | 4 | ||
| Lateral stamen (cross-pollinated) | 11 | 19 | ||
| Central stamen (cross-pollinated) | 11 | 12 | ||
| Staminode (cross-pollinated) | 0 | 3 | ||
| Treatment III: interspecies hybridization | ||||
| Lateral stamen | 14 | 12 | ||
| Central stamen | 11 | 12 | ||
| Staminode | 1 | 0 | ||
Five flowers were tested for each trial; therefore, a maximum of 25 seeds could have matured.
