US Patent 11910794 Solutions and methods for long-term pollen storage

The invention provides novel solutions and methods for storage and delivery of pollen to a female reproductive part of a recipient plant. The pollen storage solution provided includes a solute that maintains the tonicity of the pollen storage solution at a concentration between about 0.5 M and about 3.0 M and a cryoprotectant. The methods provided include storing the pollen storage solution and applying pollen stored in the storage pollen solution to at least a first female reproductive part of a recipient plant, thereby pollinating the female reproductive part with the stored pollen from the donor plant.
