Abstract
Near infrared reflectance spectra were used to estimate nitrogen lignin and cellulose concentrations in fresh foliage samples. The spectra of sixty samples from 8 species (4 deciduous 4 conifer) were measured from llOO-2500nxn when the samples were both fresh and dried. Existing regression equations relating near infrared reflectance to sample composition were used to measure concentrations in the dry ground samples. Multiple linear regressions were then used to derive equations relating spectral measurements of the fresh samples to constituent concentration. Results suggest that these constituents can be measured in fresh foliage samples using high resolution near infrared reflectance spectroscopy. 1.
