ABSTRACT: Carex physodes is an ephemeral species in the cold desert of Gurbantunggut in Northwest China. It has both asexual and sexual reproductive patterns. The primary aims of this study were to characterize the reproduction systems and identify the role of fruit dispersal in the sexual reproduction of C. physodes. Aboveground and underground biomass, root-shoot ratio, inflorescence biomass, fruit-set of C. physodes were measured and dispersal of perigynia and achenes in the natural habitat and indoor condition were studied. The underground biomass of C. physodes was approximately 10 times more than the aboveground biomass. The most parts of aboveground biomass is allocated to the inflorescence, which suggests that C. physodes allocates most biomass to... |
