Abstract
Described are methods of field conditioning cereal crop pollen. A method of the present invention includes collecting fresh pollen and introducing the pollen to field conditioning conditions which regulate pollen moisture content. The field conditioning conditions may include a relative humidity ranging from about 50% to about 100%, a temperature ranging from about −10-10° C., and an air pressure ranging from about 15 kPa to about 150 kPa. The field conditioning conditions may further include a continuous, adjustable positive or negative air flow and/or and 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 40% to about 58%, such as about 50% to about 57%.
