Abstract
Described are methods of preserving pollen, which may be subsequently stored. A method of the present invention includes collecting fresh pollen and introducing the pollen to a controlled environment which regulates pollen moisture content. The controlled environment may have a temperature ranging from about −10-10° C.; an adjustable and programmable relative humidity; a continuous, adjustable positive or negative air flow; and a flow of one or more continuously refreshed, selected gases which displace oxygen. In another embodiment of the method, the controlled environment may have a relative humidity from about 50-100%; a temperature from about −10-10° C.; and air pressure from about 15-150 kPa. In all embodiments of the method, an optional field conditioning step may be performed. The field conditioning step may include subjecting the pollen to an environment controlled for relative humidity, temperature, and air pressure such that the initial pollen moisture content may be adjusted to a target moisture content.
