| Research Abstract |
To understand the adaptive strategy of flowering plants against rainfall-damages, I observed the flowering behaviors of various plants before and after rainfall. Many plants closed their flowers under rainfall. Some species closed their flowers in response to the beginning of rainfall. Some other species did not open their flowers before the beginning of rainfall. That may be flower behaviors in response to high humidity or weak sunlight. The other species kept flowers open under rainfall. Many of these species had bell-shape flowers and guarded anthers from raindrops. However, some of these species did not protect their anthers. In these species, the numbers of flowers or anthers may be important for their success.
