Impact of habitat on pollen germination in roses
Tóm tắt
Morphological and physiological quality of the pollen was studied in fourRosa species growing in habitats with different calcium carbonate content. In soils rich in calcium the pollen showes in all cases better physiological quality which is an assumption for good fertility. It may be also one of the reasons for species diversity and population abundance of roses in native habitats on calcareous soils.
