Evaluation of seed vigor and malting quality of microwave irradiated barley seed

Several barley (Hordeum vulgare L.) cultivars, grown in Fargo and Casselton, ND, in 1984, were exposed to various levels of microwave radiation to investigate their effect on seed dormancy, seed and seedling vigor, malt quality parameters and interactions with cold and room storage systems. Radi...
