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.
