| Both species use a mixed breeding system, consisting of xenogamy, geitonogamy, and autogamy. |
| Artificial pollination experiments showed that T. sinense is self-compatible, with facultative xenogamy and no indication of agamospermy. |
| Fruits produced by autogamy and geitonogamy had larger size and lower seed number and mass than those derived from natural pollination and xenogamy. |
| However, the fruit set, seed mass and germinate rate from autogamy are significantly lower than that from xenogamy and control. |
| Likewise, there was no difference between the xenogamy treatment and corresponding controls. |
| Treatment O was conducted to examine xenogamy through artificial pollination using pollen from flowers 5 m away, but within the same population. |
