Abstract
Described are methods of preserving cereal crop pollen and/or anthers. A method of the present invention includes collecting fresh pollen and/or anthers and introducing the pollen and/or anthers to field conditioning conditions which regulate pollen moisture content. The field conditioning conditions may include a an air flow at a humidity ranging from 0% to about 99% and a temperature ranging from about −10-10° C. The field conditioning conditions may further include a flow of one or more continuously refreshed, selected gases. The field conditioning conditions may dehydrate the pollen to achieve a pollen moisture content of about 15% to about 35%.
