Abstract:

The experiment was carried out to understand the storability of onion seeds by subjecting to different modified atmospheric storage conditions with different combination of gases like carbon dioxide, oxygen and nitrogen at different concentrations. The experiment was consisted of seed storage of onion (Arka Kalyan) under modified atmospheric storage conditions. There were 15 treatments and the experiment was carried out in Completely Randomized Block Design in four replications. Observations on various seed germination parameters were recorded bimonthly. Seed germination parameters differed significantly due to modified atmospheric storage conditions in all the 12 months of storage irrespective of the modified atmospheric conditions. The seeds stored in Cold storage (T15) recorded maximum seed germination of (81.01 %), seedling growth rate of (1.84), speed of germination of (42.77), coefficient of seed germination of (0.04), shoot length (7.92 cm), root length (7.74 cm ) and seedling dry weight of (19.81 mg) after twelve months of storage period followed by T1: 80 % CO2 : 05 % O2 : 15 % N2 (72.32 %) and seeds stored in vacuum (T13).The lowest seed germination of (42.67 %), seedling growth rate of (0.64), speed of germination of (30.27), lowest coefficient velocity of seed germination of (0.00), shoot length (9.46 cm), root length (6.48 cm) and seedling dry weight of (13.00 mg) was noticed in seed stored in cloth bag (T14) followed by the second the lowest recorded in seeds stored in polythene bag with air (T12) after twelve months of storage.
