Results of the chemical imaging method based on multivariate calibration model coupled with calibration transfer. White light images of three transverse sections corresponding to MY, BT, and DSH (a–c, respectively); cellulose distribution images corresponding to MY, BT, and DSH (d–f, respectively); lignin distribution images corresponding to MY, BT, and DSH (g–i, respectively); and hemicellulose distribution images corresponding to MY, BT, and DSH (j–l, respectively). The numbers on the right of the color bar indicate the percentages of the lignocellulosic content
