Seweta Srivastava, Asha SinhaThe first count for germinated seeds was taken 5 days and the second 7 days afterplating, respectively.Determination of Moisture content of Fresh and Stored Jatropha Seeds :About 5 to 6 g Jatropha curcas seeds were accurately weighed in a Petri dish andkept in hot-air oven maintained at 110 o C for 4 hours. After cooling in a dessicator, theloss in weight was recorded in each case. This procedure was repeated till constantweight was obtained (Nayak and Patel, 2010). The moisture content of seeds wasdetermined with the help of the formula given below:Initial weight of seeds - Weight of seeds after dryingMoisture content of seeds (%) = -------------------------------------------------------------------------- X 100Initial weight of seedsStatistical Analysis: Mean value with standard error was calculated to check the variationin per cent germination and moisture content of Jatropha curcas L. seeds during oneyear of storage. The term 'Standard Error' of any estimate is used for a measure of theaverage magnitude of the difference between the sample estimate and the populationparameter taken over all possible samples of the same size, from the population (Chandel,2002).RESULTS AND DISCUSSIONData presented in Table-I reveal that fresh Jatropha seeds showed maximumgermination and in storage percent germination was decreased. After 3 months,maximum germination was shown by control by using blotter method i.e., 90% followedby multi-pot tray method i.e., 88.16% and minimum germination was shown byPenicillium rubrum infested seeds in earthen pot i.e., 66.67%. After 6 months, maximumgermination was shown by control in earthen pot i.e., 83.33% followed by multi-pottray method i.e., 80.26% and minimum germination was shown by Penicillium rubruminfested seeds in earthen pot i.e., 62.50%. After 9 months, maximum germination wasshown by control in earthen pot i.e., 75% followed by multipot tray method i.e., 73.68%and minimum germination was shown by Aspergillus fumigatus, Penicillium rubrumand Fusarium chlamydosporum infested seeds in earthen pot and in blotter method i.e.,50%. After 12 months, maximum germination was shown by control in multiport tray i.e.,71.05% followed by earthen pot method i.e., 66.67% and minimum germination wasshown by Aspergillus fumigatus Fusarium chlamydosporum infested seeds in blottermethod i.e., 30%.66
