东兴金花茶和同域分布的近缘广布种长尾毛蕊茶生殖生态学特性比较研究

东兴金花茶与长尾毛蕊茶均为山茶科山茶属植物。相同群落中濒危植物和近缘广布种生殖生态学特性的差异性能更好地阐明濒危植物的致濒原因。东兴金花茶座果率低和败育率高可能是其濒危的主要原因。本项目拟以交配系统和基因流两方面为重点，对濒危植物东兴金花茶与同域分布的近缘广布种长尾毛蕊茶生殖生态学特性比较研究。采用微卫星（SSR）分子标记技术，通过亲本分析，探讨东兴金花茶与长尾毛蕊茶群体交配系统和基因流，阐明东兴金花茶和长尾毛蕊茶的有效花粉的传播距离和交配系统类型；分析影响其交配系统和花粉流的影响因素。最后将两个物种生殖生态学特性相关参数进行比效，揭示东兴金花茶濒危的生殖生态学方面的原因，为制定东兴金花茶有效的保护策略提供科学依据。

Camellia tunghinensis and Camellia caudata are plants of the camellia genus. Differences of reproductive ecology characteristics between endangered plant and Its Widespread Congener species in the same community can clarify the Endangered reasons of endangered plants. Low fruit rate and high abortive rate of Camellia tunghinensis maybe are the main cause of its endangered. Comparative studies on the reproductive reproductive ecology of an endangered species C. tunghinensis and Its Widespread Congener C. caudata will be made in order to explore the endangered mechanism of C. tunghinensis , focusing on two aspects of mating system and gene flow. Using SSR, we will analysis the mating system and gene flow of C. tunghinensis and caudata based on parentage analysis, revealed the dispersal distance and pattern of effective pollen and analyzed the factors that would affect the mating system and pollen flow.Finally , It will reveal endangered reasons of reproductive ecology of C. tunghinensis by Comparative parameters of reproductive ecology between two species. The results will provide information for scientific and effective protection strategy of . C. tunghinensis.
