| Outline of Final Research Achievements |
The quantitative composition and distribution of the secondary metabolites and nutritional substances in the inner and outer bark of Kuril larch (Larix gmelinii var. japonica) and Japanese larch (L. kaempferi), and their interspecific hybrid F1 (Larix gmelinii var. japonica × L. kaempferi) were investigated. In this study, it was shown that the strategies of chemical defense in the bark of these Larix species would be metabolites and the resistance to species of natural enemies (e.g. small herbivorous mammals, insects, and tree pathogens).
