Long-Term Storage of Raspberry Pollen

Abstract

Plant breeders are sometimes faced with the necessity of storing pollen for extended periods of time. When pollen is stored in such standard facilities as a refrigerator or home freezer, it remains viable for only a few weeks at best. The development of a reliable method to store pollen for extended periods would facilitate crosses among plant with poor blooming synchrony. While investigating in vitroraspberry pollen germination, we found a simple storage method that greatly prolonged pollen viability.
