Abstract:

Dolichandra unguis-cati is an invasive alien vine native to tropical America.It was first introduced into cultivation as an ornamental plant,and then,with the expansion of growing areas,it has seriously harmed the urban ecological landscape and species diversity.In recent years,with the economic globalization and climate change,D.unguis-cati has shown a serious invasion in the south,especially in some major coastal cities.If not prevented,it may develop into a serious invasive species.At present,there is little research on D.unguis-cati in China,and little understanding of its characteristics.On the basis of collecting relevant literatures at home and abroad,this paper summarized and analyzed the main research status of D.unguis-cati from three aspects:reproductive strategy,growth strategy and competition strategy.The results showed that tuber propagation strategy,motility,polyembryology,low leaf building cost and litter legacy effect were the main causes of the invasion.Through research and analysis,the purpose is to reveal the origin and general characteristics of the invasiveness of D.unguis-cati,and clarify the control technology and utilization value.At the same time,this paper explored the research blank points,in order to provide a reference for further in-depth study of the invasion characteristics of D.unguis-cati,to provide a scientific basis for early warning,control and value utilization.

Key words: Dolichandra unguis-cati, invasive liana, intrusion strategy, prevention and control technology, application value
