“…Various authors have carried out the usual botanical detection reactions for the most important cell wall substances in sliced thin sections, in particular, the methods for detection of lignin with phloroglucinol, of cellulose with chlorozinc iodide, and of cutin with Sudan III , HOLLING [1958], KONONOVA [1961], FRERCKS andPUFFE [1964], BABEL [1964aBABEL [ , 1964b; for literature on the methods, see introduction to Section VI.). BABEL [1972b] has applied these reactions-in combination with optical methods-also to debris preparations of the fine substance.…”

“…The light refraction and birefringence of the morphologically fully intact cell wall regions apparently remain unchanged. In partially decomposed Ericaceae roots and Sphagnum, a weaker cellulose reaction with iodine-potassium iodide and sulfuric acid was found (FRERCKS and PUFFE [1964]). Leaf residues (occurring transversely), partly with unchanged leaf-browning substances (right part of the center leaf, piece of leaf below center), partly with darkened browning substances (top left), partly after decomposition of the browning substances and then still showing well the colorless unchanged cell walls (center).…”
