Trial on preservation of corn seed quality in airtight storage was carried out at Uniseeds Co., Nakhon Rachsima province during October-December 1996. The 10 tons sacks of corn seed var. Suwan No. 1 were stored in tailored PVC sheet namely "Volcani cube" with 0.8 mm thickness and 15 cubic m in volume. The cube was placed outdoors for 3 months and the observations were made at 2 week intervals to determine mainly on temperature, relative humidity and seed moisture contents inside the cube. After three months, the cube were uncovered to observe grain damage by insect, number of insects, mould infection, germination percentages, moisture contents of seed, temperature and relative humidity compared to before treatment and control. The results indicated that the cube could preserve corn seed quality. Insect infestation and number of live insect were not observed, Mould infection precentages were not increased and aflatoxin was not detected. Seed moisture contents, germination percentages, temperature and relative humidity before and after treatment were slightly differences and the seed were still in good condition.
