A detailed investigation of the receptive surface of the stigma of a dimorphic taxon, Linum grandiflorum, was carried out using scanning electron microscopy, cytochemistry and polyacrylamide gel electrophoresis. The stigma surfaces of the pin and thrum morphs showed distinct differences. The stigma of the pin morph was of the dry type and the papillae were covered with a uniform cuticle-pellicle layer. The stigma of the thrum morph, on the other hand, resembled the wet type; the cuticle-pellicle layer was disrupted at places and a secretion product was released onto the surface of the stigma. Coomassie blue staining material was present on the surface of only the thrum stigma. Although esterases and acid phosphatases were present on the stigma of both the morphs, their activity was invariably higher on the thrum stigma. Polyacrylamide gel electrophoresis of stigma leachates also showed distinct differences in the protein profiles of the two morphs.
