Nicotiana Tabacum L., cv. NC2326, Burley2l and Sohyang seeds were coated with different five materials - zeolite, serpentine, coal briquet ash, serpentine+zeolite and coal briquet ash+zeolite - to investigate the effects of coating on germination. The coating materials had different characteristics and gave varied effects on germination. Among three tobacco varieties, coated seeds of Burley2l showed the most sensitive responses in germination rate of decreasing and delaying at low temperature on seedbed and laboratory tests.
