Research progress on the regulatory mechanisms of the growth-defense tradeoff for forest regenerated seedlings
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.
