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.”

Well now…that certainly puts a whole new spin on “soil ammendments” one could take into consideration when planting roses! So for calcium carbonate, should we all move to the desert or Colorado to hybridize now?? Or perhaps just set up a few pollen banks out there?? LOL

How would I obtain a full copy of this paper?

I’ve heard about this a long time ago, on Karl King’s website, or else where.

Very interesting!

This could also explain why such a number of roses where obtained in France, where chalky soils abound -BTW,same reasoning with the good wines-.

This said, there are many rootstocks in use that do not like chalky soils…

Best wishes,

Pierre.
