Pollen viability was tested in two hybrid swarm populations of Pinus mugo and P. sylvestris in northern Slovakia and in control populations of the parental species. It was significantly reduced in hybrid populations, as evidenced by average germination percentages ranging from 49.0% and 61.53% and by pollen tube length averaging 74.54-86.47 µm. The corresponding values in the control populations were 78.38-88.5% and 102.92-152.84 µm, respectively. The frequency of microsporogenesis disturbances at the tetrad and mature pollen stages was higher in hybrid swarms than in the control population of P. sylvestris. Based on in vitro germination data, the amount of sterile pollen was estimated at 40-41% in hybrid swarm populations, 12% in P. sylvestris, and 21% in P. mugo.
