Summary:The physiological aspects of tobacco seeds from seeding to germination under light and dark condition, and different temperature were studied to obtain basic information on the production of good seedlings. There were distinct three phases in moisture uptake and respiration process during germination that classifiable into "Imbibition", "Lag", and "Growth" phase under light condition but such growth phase were not observed in the dark germination. Great changes of sugar and fatty acid content of tobacco seeds observed during germination in light condition but such changes were slight in dark germinated seeds. Fatty acid content of seeds during germination decreased corresponding to the increase in respiration
