Abstract :The self-incompatibility insert ignore into journalissuearticles values(SI); of 3 Middle East Veronica species insert ignore into journalissuearticles values(V. filiformis, V. gentianoides, V. teucrium); is studied, for the first time, by pollination and pollen tube growth experiments. Cytological observations of the self-pollen tubes within the pistils permit a conclusion about the presence of a gametophytic SI system in the first 2 species. The investigated population of the third is self-compatible and confirms the facultative trait of its self-sterility. The presence of a gametophytic SI system in 2 of them suggests the putative conservation of this SI system within the genus Veronica insert ignore into journalissuearticles values(Plantaginaceae); and could be related to the well-known gametophytic SI system present in the other Plantaginaceae genus, Antirrhinum.
