Characteristics of Reproductive Modules of Emmenopterys henryi Natural Population in Wuyi Mountain
摘要
Abstract
Features of the reproductive modules of Emmenopterys henryi in Wuyi Mountain, one of endangered plants in China, were investigated. The results showed that the initial time of flowering in E. henryi population presonted variability, about 7 days gap. The initial time of flowering with in population was in the middle of July, and ended in late August, its blooming period lasted 33 days. The distribution of reproductive modules related to the habitat and the position of tree crown. The number of flowers, buds and fruits in E. henryi pure population were significantly higher than other populations, but no significant difference in Phyllostachys edulis forests and conifer and broad-leaved mixed forests. In different crown layers, the middle and lower layer were significantly lower than upper layer in number of reproductive branches and reproductive branch ratio, however, south of the crown were higher than other directions.The abortive rates at flowering stage and fruit stage were higher(81.45％ and 58. 12％ ), and they were remarkable differences among the habitats and crown positions. The high abortive rate lead to low fruit yield, it is one of the reasons to make E. henryi being endangered. Principal component analysis showed that reproductive module were impacted significantly by the light, slope aspect, tree layer cover in the E.henryi population.关键词
