Abstract
|
|
|
An anthecological study of Tilia in Korean was undertaken for six native and one introduced species. Flowers are protoandrous with anther and stigma opening during the day-time in section (sect) Anastraea and the night-time in sect Astrophilyra. Nectar production was coincided with anther and stigma opening. It is revealed that the primary role of floral bracts was attracting pollinators especially in sect Astrophilyra.
The peak of stamen and stigma function, and the producting of nectar and odor were closely related with pollinator attraction. Forthy-three species of insects in 30 families were identified for the pollination studies; been were the most commonly observed visitors in sect Anastraea, while moths were the primary viistors in sect Astrophilyra. Pollination study indicate that it is section specific. But within a section, pollination is not species specific thus interspecific hybridization occurs.
