Vacuum storage of yellow-poplar pollen

Abstract

Vacuum-drying, followed by storage in vacuo or in an inert gas, is effective for storing pollen of many species. It permits storage at room environments without rigid controls of either temperature or humidity, an advantage that becomes paramount during long-distance transfers of pollen when critical storage conditions are impossible to maintain. In the study reported here, the objectives were to learn if vacuum storage is effective for yellow-poplar (Liriodendron tulipifera L.) pollen and to determine optimum rehydration conditions.
