Studies on deterioration of some oilseeds in storage: III. Effects of differenct storage temperatures and relative humidities on seed moisture germination and infection

Abstract: Seeds of two cultivars of sesame, two species of mustard and one linseed were collected after harvest, and six and 12 months later from private store-houses and stored under 80per thousand and 90per thousand RH at both 20° and 30°C. Effect of RH and temperature on seed moisture, germination and fungal invasion were studied at intervals of 21 days up to 84 days. In all cases, both seed moisture and fungal infection were higher at 90per thousand RH and 20°C than in other treatments. A gradual decrease in infection by field fungi with concomitant increase by storage fungi, accompanied by a reduction in seed germination, occurred as storage progressed. Highest loss of germinability was noted at 90per thousand RH and 30°C.
