Objective The purpose of this study is to explore the reproductive allocation (RA) of Tetracentron sinense Oliv. and the relationship between reproductive and vegetative investment, and thus investigate the life history strategies and reasons causing this species endangered. Method Using fixed-area sampling plot in Meigu Dafengding Nature Reserve, the reproductive modules biomass of individuals with different DBH(diameter at breast height)class were collected and measured. Multiple comparison analysis was conducted to compare the differences in reproductive investment and allocation among different DBH class. The relationships between RA, reproductive modules biomass and the nutrient modules biomass were analyzed by correlation and linear regression analysis. Result (1) With increasing DBH, the reproductive and vegetative investment showed the same changing trend, and no trade off appeared between them; (2) At the level of modules, the RA value increased at the beginning and then decreased with increasi
