【 摘 要 】

Research on soybean seed has revealed that conductivity test results may be influenced by storage temperature and that an apparent direct relationship between deterioration at low temperatures and loss of cellular membrane integrity is not evident. The objective of this study was to verify the influence of low storage temperatures on electrical conductivity results in other species, such as seeds of two pea cultivars studied temperatures were: 10, 20, 25, 20/10 and 25/10ºC. The physiological potential of the seeds was evaluated every three months during an 18 month storage period using germination, accelerated aging and electrical conductivity tests. The electrical conductivity test was not a good indicator for the degree of seed deterioration stored at low temperatures. Seed deterioration at 10ºC did not seem to be directly related to the loss of membrane integrity, possibly due to membrane repair or reorganization during storage at this temperature.
