Pollen grain on the compatible and incompatible stigma of Secale cereale L.

The course of pollination processes, pollen morphology and the degree of stigma pollination both in self-compatible (four lines) and in self-incompatible (two cultivars) plants of Secale cereale were examined. It was ascertained that either the self-compatible or the self-incompatible plants produced in anthers large amounts of the vital pollen, which during pollination was deposited in different manner on the stigma surface. It is worth noting that the presence of the leftovers of tapetum between mature pollen grains only in the anther of two self-incompatible cultivars was observed.
