Seweta Srivastava, Asha Sinhainhibited fungal growth, but they did not kill the fungi. Among microorganisms infectingseeds, fungi was the most tolerant to low water availability, therefore they had an importantrole on seed deterioration. Ratree, (2004) was reported that seed germination per centdeclined slowly with the longer storage periods when dry seeds stored under roomtemperature. The results indicated the slow deterioration of seeds with time. However,Pasabutr and Suthiponpaiboon, (2001) found that physic nut seed stored under roomtemperature for 8 months gave germination up to 80% but decreased to 42% after 9months storage. Therefore, it may be of high advantage to store seeds in a low temperatureas low as 20 o C where high respiration rate could be reduced, thus it may be possible toprevent the rapid deterioration of seeds since oil seeds obviously loss its vigour morerapidly with time when store in a high environmental temperature. Deng et al. (2005)was reported that the germination of 80-90% has been obtained for seeds collectedduring October to December. The seed had been dried in shade, and stored dry indoors.The seeds retained germinating ability for >2 years.CONCLUSIONIn all stored and fungal infested seed treatment combination including check, therehas been a decrease in seed germination and an increase in moisture content with theincrease in storage period. Whereas, Aspergillus fumigatus, Penicillium rubrum andFusarium chlamydosporum decreased percent germination of Jatropha seeds veryfrequently (Table-I). Aspergillus flavus and Penicillium rubrum has been increasemoisture content in stored seeds so that seeds were destroyed very fast as compared theothers (Table-II).REFERENCESChandel, S. R. (2002).
