| 英文简介 | Gynomonoecy is an important step in the evolution of monoecy from hermaphroditism in angiosperms. The sexual system of gynomonoecy is considered to play several important roles, including reducing herbivore damage to pistils, reducing inbreeding depression by favoring out-crossing and pollen-pistil interference, enhancing the flexibility of resource allocation to male and female functions in two flower types, and attracting pollinators. Eremurus anisopterus is perennial and ephemeral herb that grows on fixed and semi-fixed sand dunes of the Gurbantunggut Desert of Xinjiang and with a hermaphrodite-gynomonoecious sexual system. In this project, we investigate the floral traits of female and perfect flowers on hermaphroditic and gynomonoecious individuals, relationship between the gynomonoecious sexual system and plant size, mating system of two morphs of flowers, and germination characteristics and seedling growth of seeds from both female and perfect flowers. The results of the study could help us in exploring the size-dependent gynomonoecious of this species, and discussing the effect of these characteristics on their offspring fitness. This research will provide important reference for evolutionary significance of gynomonoecy for angiosperms and provide a theoretical framework for vegetation conservation in Gurbantunggut Desert. |
