Abstract
Sexual reproduction underlies plant invasion and spread, but the mechanism underlying reproductive success remains unclear. We tested the hypothesis that a plant's generalized pollination system promoted its invasion by using field experiments to investigate aspects of the pollination biology of Solidago canadensis, such as species, visit frequency and visit behaviour, in different populations in Xuzhou, Hefei, Nanchang and Ji’an. The field experiments supported the hypothesis that the plant’s generalized pollination system is beneficial to its invasion. S. canadensis has a complex floral syndrome that facilitates the acceptance of different types of pollinators, strongly promoting its reproductive success. We found large numbers of visiting insects on S. canadensis, and the main pollinator species were relatively stable within habitats, although the main pollinator species differed among the geographical populations. In terms of time, insect visits were observed from morning to afternoon, mainly from 9:00 to 11:00. The pollination biology results showed that S. canadensis has a generalized pollination system that could ensure successful sexual reproduction by attracting insects in different habitats and provide a basis for reproduction after invasion
