| Outline of Final Research Achievements |
Flowers are often visited by animals with different pollination efficiencies. In interacting with such a wide variety of partners, it is of crucial importance for flowers to postpone visits by inefficient pollinators as much as possible, while prioritizing visits by more efficient pollinators, which allow them to make the best use of limited floral resources or gametes. Despite this interest, the timing of anthesis is not known for most species because most of their flowers last for more than 24 hours. Therefore, I quantified flower opening time for 150 angiosperm species in Japan using time-lapse photography. I have found that the flower-opening patterns can be classified into five types, which correspond to flower shape and flowering time: "Morning type", "Day type", "Night type", "Open/closure type" and "Bimodal type".
