Localized concentrations of phenols, stored in discrete bodies within randomly scattered parenchyma cells in banana roots, were detected both by light and electron microscopy. The distribution of the phenols was comparable (i) in fresh tissues stained with aqueous methylene blue or by the nitroso reaction; (ii) in glutaraldehyde-preserved tissues similarly stained; or (iii) in glutaraldehyde-preserved tissues postfixed with osmium tetroxide and embedded in diepoxy resins.
