title: Chlorantine fast green BLL as a stain for callose in oak phloem.
abstract: Sections of oak bark were stained with chlorantine fast green BLL, used as a 0.25% aqueous solution. All tissues were unstained, except for local deposits of material associated with phloem cell walls, which stained deep green. This green-staining material also stained specifically with resorcinol blue and with the aniline blue fluorescence technique, the usual histochemical tests for callose. The chlorantine fast green-staining material was removed from sections by treatment with a beta-1,3-glucan hydrolase. It is concluded that chlorantine fast green BLL stains callose in plant sections and is a useful additional stain for the histochemical detection of this polymer.
