树木生长应力的表征及调控研究进展OA北大核心

Growth stress endows trees with the ability to resist external stress and helps maintain the stability of trunk morphology.However,in the process of wood harvesting and processing,the release of growth stress easily induces defects such as cracking and warping,resulting in volume loss.The characterization of tree growth stress is the basis for studying its formation mechanism,influencing factors and control measures.Comprehensive review of the existing growth stress characterization methods,accurate characterizing of growth stress,and study of the influencing factors and control measures are of great significance for balancing the ecological benefits of plantation forests and the economic benefits of wood utilization.This paper briefly describes the formation of growth stress,and reviews the traditional and emerging test methods,measurement site selection,test result characterization,influencing factors and control measures of growth stress.Finally,the future research on tree growth stress is discussed in order to promote growth stress research to a deeper level.
