Abstract: “Impact of habitat on pollen germination in roses.Morphological and physiological quality of the pollen was studied in 4 Rosa spp. growing in habitats with different calcium carbonate content. In soils rich in Ca the pollen had better physiological quality which is an assumption for good fertility. This may explain the high species diversity and population abundance of roses in native habitats on calcareous soils.”
