| Abstract: | Grassland gaps provide "safe sites" for seedling establishment.Many plant species need gaps for successful germination,emergence and establishment.Grassland gaps play an important role in promoting seedling recruitment.This paper reviewed the concept of seedling establishment and gap,the response of different species to different types of gap and given some suggestions on further research work.It may help to conduct the research work in this field. |
