Fig. 3From: Automated quantification of fluorescence and morphological changes in pretreated wood cells by fluorescence macroscopyFluorescence macroscope images of untreated and pretreated (170 °C, 190 °C, 210 °C) spruce and beechwood transverse sections. Brightness was optimised for each image to facilitate comparison due to differences in fluorescence intensity of samples. Optical magnifications 63 × and 258xBack to article page
