摘　　要：森林更新幼苗的生长和防御的优先度受环境因素和苗木发育特征的影响,同时又反过来影响着幼苗的生理特征。生物量分配和碳储存性状特征能够表征幼苗的成活、生长和生态适应能力。因此,通过研究森林更新幼苗生物量分配策略,探明幼苗器官中非结构性碳水化合物(non-structural carbohydrate,NSC)含量的季节动态和碳储存变异特征,对于深入理解幼苗生长-防御权衡的变异规律及其调控机制,指导森林可持续经营具有重要的理论意义和实践价值。The growth and defense priorities of the forest regenerated seedlings are influenced by envi-ronmental factors and developmental characteristics,which in turn affects the physiological character-istics of the seedlings.Biomass allocation and carbon storage traits can represent the seedling abilities of survival,growth and ecological adaptability.Therefore,the seasonal dynamics of non-structural car-bohydrate(NSC)concentration and the variation in carbon storage characteristics within seedling organs were explored through the study of forest regenerated seedling biomass allocation strategy.The findings deepen the understanding of the variation rules and regulating mechanism of seedling growth-defense tradeoff,providing important theoretical significance and practical value to guide the sustain-able management of forests.
