| Artificial pollination experiments showed that T. sinense is self-compatible, with facultative xenogamy and no indication of agamospermy. |
| Treatment O was conducted to examine xenogamy through artificial pollination using pollen from flowers 5 m away, but within the same population. |
| No differences were noted in pollen germination, pollen tube growth or fertilization between experimental tests of xenogamy and geitonogamy in S. mucugensis. |
| Likewise, there was no difference between the xenogamy treatment and corresponding controls. |
| Both species use a mixed breeding system, consisting of xenogamy, geitonogamy, and autogamy. |
| In addition, such a forum, in many cases, will develop into a xenogamy from which new 'best practices' and improvement initiatives blossom. |
