EFFECT OF SOME FUNGI ON THE VIABILITY OF SOYBEAN SEED DURING STORAGE

Abstract

Role of 8 fungi at 3 levels of temperature and 4 levels each of relative humidity and storage time was studied with respect to viability of soybean seed during storage. In general higher per cent of seeds were viable at low temperature and relative humidity and short storage period. Aspergillus flavus and A. niger caused maximum drop in seed viability at temperature 8-10°C and 25+1°C and at all the 4 levels of RH (70-92%) while A. nidulans and P. oxalicum did the maximum at temperature 7.9-42.7°C. Drop in seed viability was increased due to all the treatments as the period of storage advanced.
