Floral mechanisms promote pollination success and reduce the incidence of self-pollination in a fly-pollinated self-incompatible orchid.

ABSTRACT: Among flowering plants, self-incompatibility is considered the most efficient system for avoiding self-fertilization. However, many self-incompatible plants have also evolved floral mechanisms to reduce sexual conflict. In China, some studies of Bulbophyllum have been reported to be self-incompatible and no fruit sets. However, we have observed relatively high fruit sets in Bulbophyllum funingense. Therefore, we speculated that if B. funingense is also self-incompatible, and it might present a floral mechanism to avoid sexual conflict. Natural fruit sets, pollinia removal and deposition rates were determined and breeding system was tested in a hand-pollination experiment. The pollination process and visiting frequency of pollinators and their behavior after escape from
