摘要：We determined the variations in allelopathic potential of plant species in 4-pioneer plant communities (Community Imperata cylindrica, Community Phragmites australis, Community Phacelurus latifolius and Community Solidago canadensis) in coastal area in Cixi City, China. The allelopathic potential of species was also compared among functional groups and linked with species dominance. The results showed that main variation in allelopathic potential existed among the species and functional groups. The strength of allelopathic inhibition differed in selected functional groups: annuals/biennials > perennial species, non-clonal species > clonal species and Poaceae < other families. In contrast, the ranking pattern of species mean importance values in different functional groups was reversed. When all species from the communities are pooled together, allelopathic potential was negatively related to the importance value. In conclusion, although the substantial variations in allelopathic potential of plant species exists, but the species dominance in this community was achieved through functional traits viz., clonality and perenniality instead of allelopathy. A trade-off likely exists between traits that promote the dominance and the traits that promote allelopathy.
