| Abstract: | The receptive surfaces of the stigma papillae of Phalaris minor (Gramineae) bear a superficial proteinaceous layer outside of the cuticle. Using the peroxidase labelling technique, it has been shown that this surface layer or pellicle binds the lectin concanavalin A. Glycoproteins in the pellicle may play a part in pollen adhesion as well as in pollen-stigma recognition. |
