Pollen viability and natural hybridization of Central European species of Cirsium

Original language description

All hermaphrodite plants of the Cirsium hybrids had viable pollen, generally lower than found in pure species. The pollen viability of a hybrid generally decreased with increasing genetic distance between the parents and when the parental species had lower pollen viability. The pollen viability was decreased in frequently hybridizing species where occasionally individuals of pure species morphology may show decreased pollen viability. In populations of gynodioecious species where females co-occurred, pollen viability (in hermaphrodites) was lower, indicating inbreeding depression. Hybrids between sympatric species exhibited higher post-pollination isolation (decrease of pollen viability), which suggests that the reproductive isolation had been increased by natural selection (effect similar to the Wallace effect). The strength of the postzygotic barrier (based on pollen viability) was generally stronger than that of the prezygotic barrier (based on distribution overlap) in hybridizing s
