Fruiting phenology of Ficus curtipes in Xishuangbanna
摘要
Abstract
Phenology of plants and life history of pollinators should match and maintain their mutualism.Figs and their pollinating fig wasps form highly specific mutualism and co-adapt in the phenology and life history.Ficus cur-tipes is monoecious,which distributes widely in Xishuangbanna with special pollination system.Fig wasps on F .cur-tipes have been massively reported,however,fig trees are seldom concerned.In this paper,we address three ques-tions:(1)What are the fruiting patterns of female floral phase and male floral phase of F .curtipes ,do they match each other;(2)Are there any correlations between climatic factors and the phenolgy of F .curtipes ;(3)How can fruit-ing pattern affect fig-wasp system in F .curtipes Over 30 months,F .curtipes fruits once or twice,at most three times per year.F .curtipes occasionally fruit asynchronously within individual trees in rainy season,which may be a strategy for boosting pollinator populations.In certain months there is no overlap between male and female phases of Ficus curtipes within the population suggesting pollinators may become periodically extirpated.The duration of fe-male floral phase and male floral phase of F .curtipes are longer than that of other species in our research area,which may reflect the scarcity of receptive figs or fig wasps.Fruiting phenology of F .curtipes was perhaps most affected by relative moisture among all climatic factors in this research,however,no regular correlations between the phenology of F .curtipes and three climatic factors were found.Instead of one specific factor,the phenology of F .curtipes may be influenced by both biotic factors and abiotic factors,other climatic factors may also play a part.Hence,it will be nec-essary to conduct more correlation analyses to elucidate such complex connections.关键词
