Abstract
The exclusive oxidation of the leuco (reduced) form of common redox indicators to the oxidized and colored form by the endodermis may be induced by treating fresh free-hand or freezing microtome sections with various alkaline salts at pH 8.5 to 9. The endodermis and the collenchyma may be differentiated best by oxidation and adsorption respectively by means of Na selenite, guaiac and glycerol in the order given. The collenchyma in roots has not been defined to date, and the reactions descr. introduce a new method of study for this tissue. By treating sections witt boric acid a gradient in the guaiac reaction appears in the cortex.
