摘要: The invasiveness of alien plants is closely related to their reproductive characteristics. A compari- son characteristics an species in different habitats will help reveal its optimum habitat for invasion and the mechanism invasion. Furthermore, it provide a theoretical foundation planning reasonable management strategy. Solanum rostratum summer annual weed native neotropics southwestern USA that produces offspring only by sexual reproduction. This has become established seven provinces/cities China, including Xinjiang. We compared char- acteristics S. oasis, desert grassland gravel Xinjiang determined results were as follows. (1) Single-flower duration was between 27 47 hours. Daily flowering time single-flower similar among three habitats. However, number flowers per individual differed (P > desert. (2) Halictus quadricinctus, sp. Xylocopa latipes pollinators
