The effects of various atmospheres, such as oxygen, carbon dioxide, nitrogen, and a partial vacuum on the viability of stored seeds have received only limited attention, while the effects of seed moisture content and storage temperature have been studied extensively. Only a few of the more salient papers are reviewed here; see James (7) for a comprehensive r view of the 20th century English language literature on seed storage. Ghing et al. (3) reported that crimson clover seeds containing 6% moisture remained highly viable during 3 years of storage at temperatures as high as 100.4° F., but seeds with high moisture content deteriorated rapidly except at 37.4° F. Crimson clover seeds respired less than perennial ryegrass seeds held in sealed storage (2). Respiration was accelerated more by an increase in seed moisture than by an increase in storage temperature. The concentration of CO~ did not seem to affect seed respiration. Davies (4) reported that both white and red clover seeds were shorter lived when stored under vacuum or in N2 than when stored unsealed. According to Evans (5) red clover seeds containing 10.32% moisture lost all viability during 23 years when stored untreated or sealed in CO.at laboratory temperature. When CaCh or CaCla plus CO= were used in the storage containers the seeds lost only one-third of their viability during 23 years. According to Goodsell et al. (6) cold test germinations for corn were, in general, no higher for CO~or N~-stored seeds than for air-stored seeds except that 12% moisture seeds at 60° F. in air germinated relatively less than comparable seeds stored in CO2 and N~. Struve~ reported that O= may become an important factor in the deterioration of corn seeds tored sealed in air at temperatures as low as 95° F. in less than 10 months. The O~ effect was magnified by increased O.~ concentration, higher temperature, or longer storage. Seeds tored in pure N.maintained better viability and vigor longer than seeds stored in O.~. Sayre (8) detected no advantage in storing corn seeds in gases other than air.
