| 英文简介 | Gymnocarpos przewalskii；gene flow；Pollen dispersal；seed dispersal；clonal growth Plant strategy in life history is related to plant adaptation or evolution , ecosystem degradation or restoration , and biodiversity conservation , which are the components of theoretic and applied ecological studies. The Gymnocarpos przewalskii, a rare ancient relict species in the northwestern desert of China, the species not only has both sexual and asexual reproduction, but its reproductive strategy relate spatial heterogeneity. Gymnocarpos przewalskii was studied in the project. several study concerning the relationships between plant strategy in life history and environments, The adaptive mechanism and evolutionary significance of strategy in life history to the desert habitat are analyzed by researching gene flow (pollen flow and seed flow) and clonal growth characteristics of natural populations under different environments, which not only provide the important theoretical evidence for the comprehension of Gymnocarpos przewalskii evolution and the adaptive mechanism to the desert extreme environment, the endangered mechanism of ancient relict genus and protective strategy, but also provide new evidence for the research to the evolution of plant reproductive strategy, and accumulate important theoretical information for studying the flora occurrence and development of Central Asia and discussing adaptation and evolution mechanism of the genus to the western desert environment in China. |
