Fig. 5From: Rapid determination of chemical composition and classification of bamboo fractions using visible–near infrared spectroscopy coupled with multivariate data analysisVisible–near infrared mean spectra from original data of bamboos. Ten spectra were collected from 2- and 10-year-old mature bamboo and other 10 spectra were collected from 2-, 4- and 6-meter-height juvenile bambooBack to article page
