The freshly harvested seeds were exposed to various combinations of inert gases viz., T1- 80% CO2+5% O2+15% N2, T2-75% CO2 +5%O2+20% N2, T3- 50% CO2+5% O2+45% N2, T4-25% CO2+5% O2+70% N2, T5-20% CO2+5% O2+75% N2, T6- 15% CO2+5% O2+80% N2, T7-50% CO2+00% O2+50% N2, T8- 50% CO2+10% O2+40% N2, T9-25% CO2+10% O2+65% N2, T10 - 20% CO2+10% O2+70% N2, T11-15% CO2+10% O2+75% N2, T12 -100%CO2+00% O2+00% N2, T13 -00% CO2+00% O2+100% N2, T14-Vacuum packing, T15- seeds stored in polythene bag with normal air, T16-storage in cloth bag (control). The results revealed that, the seeds stored with gaseous combination of 80% CO2+5% O2+15% N2, in 700 gauge polyethylene bag maintained better quality traits in terms of germination (82.45%) and vigour (2469) up to the end of twelve months of ambient storage by recording higher root length (18.47 cm), shoot length (15.96 cm), dehydrogenase enzyme activity (0.268 OD value), oil content (17.34%), protein content (36.49%)and less seed leachate (1.093 dSm-1) and minimum moisture content (8.024%) followed by vacuum packaging storage (Germination -81.23% and 2355)compared to those stored in polythene bag with atmospheric air and in cloth bag. It is also seen that seeds stored in polythene bag with 80% CO2+5% O2+15% N2 retained germination above minimum seed certification standard even at the end of twelve months storage period. The same results were also seen in vacuum packaging and seeds stored in polythene with 75% CO2+5%O2+20% N2 where as it was only up to seven months and five months period in case of polythene bag with normal air and cloth bag respectively.Thesis
