Flue-cured tobacco seeds "Coker 187-Hicks" harvested in 1977, were subjected to preserve viability by stored in various containers and in two conditions. Seeds were kept in cotton bag over silica gel in the containers. Laboratory tests for germination of seed were done monthly from September 1977 to March 1983 and every two months from April 1983 to March 1986, at Mae Jo Tobacco Experiment Station, Chiang Mai. The results in 1985-1986 showed that the germination of seeds stored in glass bottle under refrigerator conditions in preserving jar under refrigerator conditions, and in preserving jar under laboratory conditions were somewhat high (more than 90%) throughout the year. Percentage of seed germination stored in desiccator under refrigerator and laboratory conditions slightly declined in August 1985 and February 1986, respectively. Average percentages of seed germination were as followed: 95.33, 95.33, 93.22, 93.05 and 91.94 percent from treatments 1,2,4,3 and 5, respectively.
