SummaryPetri plate culture of almond pollen in a basic mineral media with 10% sucrose and 2% agar enables optimum germination and tube growth of field-collected samples. Tests over one blooming season indicated that damp weather and an advanced stage of flower dehiscence are associated with low pollen germination. Pollen from honey-bees foraging for pollen germinated more readily than pollen from bees foraging for both nectar and pollen, or for nectar exclusively.
