| Outline of Final Research Achievements |
To clarify storage resources linking masting based on the resource budget hypothesis, we investigated a sequential variation of quantity of resources (non-structure-related carbohydrate (NSC) and nitrogen (N) ) stored in the Betula maximowicziana trees during five years including two masting years. Masting cycle of B. maximowicziana was related with NSC storage. NSC accumulated in the whole tree body during non-masting years, whereas N storage was relatively constant. The NSC density of the trunk, i.e., a large-capacity and low-priority storage organ, was clearly indicated the masting cycle.
