摘 要:The internal cycling of nitrogen(N)storage and consumption in trees is an important physiological mechanism associated with tree ***,we examined the capability of near-infrared spectroscopy(NIR)to quantify the N concentration across tissue types(needle,trunk,branch,and root)without time and *** NIR spectral data of different tissues from slash pine trees were collected,and the N concentration in each tissue was determined using standard analytical method in laboratory.
