Girdling is a common technique in pomiculture.This paper summarizes the wound healing mechanism after girdling,and discusses the regulation mechanism of girdling on plant carbohydrate balance,water balance,flower bud differentiation,photosynthesis and fruit appearance.Then put forward the technical advantages of non-invasive girdling,and reviews its research progress.This article provides a theoretical basis for further research on the non-invasive girdling technology.
