No polysaccharide demonstrated in filamentous structures in sieve elements by theiry's periodic acid-thiocarbohydrazide-silver proteinate method for electron microscopy.
By means of Thiery's Periodic acid-thiocarbohydrazide-silver proteinate method, for electron microscopy, it has been demonstrated that the filamentous structures of sieve elements contain no polysaccharide component.
