In order to explore the natural regeneration characteristics of the dominant tree species Fagus lucida in Kuankuoshui National Nature Reserve, the seed embryo development and the diameter class structure of large-diameter ancient tree community were investigated. The results showed that almost all embryos of F. lucida in Kuankuoshui Nature Reserve were aborted in 2021; large number of nuts does not mean that a sufficient number of active seeds can be produced; the natural regeneration of F. lucida forest with large diameter is particularly difficult because of the lack of seedlings and young trees; there are serious diseases and insect pests in the nuts of this tree species, which aggravates the difficulty of natural regeneration. %K 亮叶水青冈,天然更新,径级,种胚败育
