From: Label-free visualization of fruit lignification: Raman molecular imaging of loquat lignified cells
Microscopic images of loquat flesh cells. a Bright field images of the flesh cells; b Fluorescence images of lignin distribution in the flesh cells strong blue autofluorescence signals were found present in the sclerenchyma cells whereas the parenchyma cells were observed with scarce autofluorescence signals; c Sections stained with phloroglucinol–HCl, sclerenchyma cells were observed stained pink-red.
