I have heard that pollen mixtures are used to somehow facilitate difficult crosses.  Maybe they take up the receptors or burn up the S proteins so the pollen tubes can sneak into the style to reach the ovary?  I wonder what mechanism of incompatibility exists in the Amaryllidaceae.  I know that tomato and brassicas have two different mechanisms in the classic studies of self incompatibilities.
   
  I've also heard that breeders sometimes mix pollen with lily stigma exudate and inject it into the style or ovary.
