摘　　要：Woody plants in forests play a central role in sustaining ecosystem function and serve as renewable sources of energy.Perennial trees in temperate and boreal regions exhibit seasonally synchronized shoot growth and wood production,as revealed by bud growth-dormancy cycles and tree-ring formation.To survive harsh winters,trees undergo vegetative growth cessation in late summer or early autumn,impacting the duration of wood production and wood quality.However,deciduous trees in frost-free temperate and subtropical regions may experience limited atmospheric carbon assimilation and biomass accumulation due to seasonal dormancy.Thus,understanding the regulatory networks governing the seasonal growth of trees could facilitate the generation of desirable tree germplasm suited for different climate zones.
