Floral morphology and reproductive biology in selected maple ( Acer L.) species (Sapindaceae)

摘要: This study focuses on variation in reproductive systems Acer (maple) species, and how might be a useful genus for understanding floral morphology the evolution of these highly variable systems. The goals were (1) to conduct survey characters with an emphasis morphometrics A. ginnala Maxim., tataricum L., hybrid ginnala × tataricum (2) present compilation biology based literature online information. Morphometric analyses showed that exhibits intermediacy vegetative some traits compared parents. Literature revealed information 40 plus hybrid, representing only 32.3% taxonomic diversity. modes include monoecy, dioecy, trioecy, andromonoecy, androdioecy, andropolygamy, trend towards unisexuality. Temporal patterns maturation parts duodichogamy, heterodichogamy, simultaneous, dichogamy. pollination syndrome is entomophilous, anemophilous, ambophilous. We conclude evolutionary geographic success lie versatility sexual systems, diverse organs, success, ability colonise wider areas.
