| Outline of Final Research Achievements |
I established a measurement method for the volume of floral nectar secretion in impatiens without any damages of the floral parts. The nectar secretion began just before the flowering, and the floral nectar was produced in almost constant rate at daytime, but it had never been observed during night. The secretion rate was 1.0microliter per hour approximately. Just after a visiting of a bumblebee, the volume of floral nectar was 0.7microliter, and almost flower visitors flied away form the flowers before probings. At 15 minutes after the last visit, all visitors got the floral nectar. The nectar volume 0.3microliter may be the adaptive point for the both of the rewards and the cost for bumblebee pollination.
