摘　　要：木本植物次生木质部生成是木材质量和产量形成的基础,次生木质部生成受外部环境因子和自身遗传调控双重因素的影响。本文以杨树等主要树种为例,概述了木本植物次生木质部的形态结构、形成过程,重点阐述了外部环境因子对木质部生成的影响以及次生壁主要成分纤维素、半纤维素、木质素合成基因的研究进展,以期为木本植物木材产量和质量形成研究提供借鉴和依据。The process of secondary xylem formation in woody plants determines wood quality and yield.Genetic regulation of this process,in combination with environmental factors,influence this process.In this paper,the understanding of and research on secondary xylem formation and wood morphology in Populus species around the world is reviewed and summarized to provide insights to the yield and quality of wood.In this review,special attention is given to the effects that environmental factors and genes controlling synthesis of the main components of secondary cell-walls(cellulose,hemicellulose and lignin)have on xylem formation.
