  • Publication number: 20250098665
    Abstract: Maize pollen is notoriously fragile and susceptible to degradation unless adequately stored. Unlike some tree pollen, which can be quite hardy and capable of successful fertilization for months or years after it is shed, maize pollen remains viable for mere hours after shedding before it begins to degrade. Described here is an invention for storing maize pollen where the pollen is collected and stored in a refrigerated, but not frozen, environment with a breathable barrier. Pollen stored as described herein may remain viable for up to twelve days, or two weeks, or longer. Adding a carrier compound can extend viability of the pollen.
