Resting barley seeds stored under oxygen at a pressure of 100 lb/in.2 for 4 and 6 weeks exhibit a significant number of chromosome aberrations and mutations. The amount of cytogenetic damage increases with length of storage. The frequencies and types of changes are similar to those induced by 500 r to 1000 r of x-rays.
