Self-incompatibility in Miconia ciliata (L.C.Rich.) DC. (Miconieae-Melastomataceae)

Miconia ciliata is a shrub whith flowers over a period of 11 months. The flowers are hermaphrodite with diurnal anthesis. Probably Miconia ciliata exhibits gametophytic incompatibility - pollen tube growth's interrupted in the style. Bees of the family Halictidae were observed to use the vibration technique to extract pollen (buzz pollination). Only few flowers per inflorescence open each day. which probably induces the effective pollinators to visit a larger number of inflorescence in each individual plant, promoting cross pollination. Reproductive success in Miconia ciliata is favoured by the high frequency of pollinators visits, high P/O ration and high pollen fertility.
