| Outline of Final Research Achievements |
Year-to-year variation in the amount of flower and fruit can be seen in many plant species. In this study, I conducted following analysis. 1) investigating the changes of the amount of the flower and fruit by the field experiment manipulating the environmental conditions, 2) figuring out the gene expression changes that occur from flower bud formation to seed maturation under the same experimental environment, 3) extracting the proximate factor causing the annual variation, using two Quercus species. The high temperature had a possibility to affect positively for current fruiting, while it had negative effect for flowering in the following year. In addition, fertilization experiment suggested that nitrogen may alleviate the requirement for seed production, even if a factor to determine seed amount except nitrogen availability (e.g., temperature or precipitation) was inappropriate.
