摘要: We investigated inter-specific variation in fruit characteristics — size, seed number per fruit, weight, nutritional content, persistence, and synchronization relation to flowering fruiting phenology 34 species of fleshy fruited plants. Except for aspects synchrony the results general were inconsistent with previous suggestions about adaptive phenologically related traits. The main as follows: (1) Late flowering, late fruiting, lengthy development time from flower highly persistent fruits constitute a complex correlated among species. (2) Synchronization within individuals increased early ripening fruits. Fruiting was more pronounced small crop size than large crop, whereas not significantly synchronization, nor life form. (3) Nitrogen carbohydrate content pulp did vary phenology, lipid decreased (4) No seasonal trends found or fruit. (5) Interactions developmental constraints are important phenological patterns. Temporal start partly (36%) explained by time. Seed weight 17% (6) Despite development, some adjustment is likely be allowed Such an suggested intra-generic comparisons Prunus Vaccinium
