Tree allometry often differs across coexisting species of different functional types, such as adult stature and regeneration light environment. Difference in tree allometry across species may reflect that in shoot growth patterns. In addition, reproductive status would also affect shoot structure because fruits should be positioned without mechanical failure. To our knowledge, no studies have related height-dependent changes in shoot structure to tree allometry for the species of various functional types by considering these multiple factors simultaneously. We examined height-dependent changes in shoot structure of 12 species in Kamigamo Experimental Forest, Kyoto University. Species of wide range of adult stature, leaf habits (evergreen and deciduous), sexual expression (monoecious and dioecious), and regeneration light environment (high and low light) were chosen. In the poster, we focus on the following questions: (1) are height-dependent changes in shoot structure related to adult stature and tree allometry? (2) do they differ between evergreen and deciduous species? (3) do they differ between male and female trees of dioecious species? (4) does light environment alter the patterns of height-dependent changes in shoot structure? Based on the results, we discuss the importance and regulating factors of height-dependent changes in shoot structure.
