Abstract
Pollen malformation and ploidy levels in Ranunculus grex parnassiifolius. A survey of pollen malformation in Ranunculus grex parnassiifolius, a polyploid complex distributed from the northwestern mountains of the Iberian Peninsula to the most alpine massifs, is presented. The most remarkable result is the low viability of pollen in tetraploid populations (85.27% of nonviable pollen) compared to diploid populations (17.72%); and is considered as a proof of the existence of partial reproductive apomictic processes.
