Abstract: Patterns of biomass allocation among organs in plants are important because they influence many growth processes. The Yunnan-Guizhou Plateau (YGP) is considered to be one of the most sensitive areas in China to climate changes, but we know little about how current climatic gradients on the plateau influence plant biomass allocation. Gentiana rigescens and G. rhodantha, on the YGP, are important species because they are used in traditional Chinese medicines. We therefore analyzed the biomass allocation patterns of the two species across an elevation gradient (1000–2810 m a.s.l.) on the YGP to understand and predict the impact of climate Received: 08-Jun-2020 Revised: 27-Jul-2020 Accepted: 24-Sep-2020

change on these plant species. We found that the total biomass, reproductive biomass, vegetative biomass, aboveground biomass, and belowground biomass in G. rigescens were all significantly larger than those in G. rhodantha (p
