| Popis: | The germination potential (viability) of soybean is short lived owing to its high susceptibility to mechanical injury and damage occurring during post-harvest handling. This adversely affects the viability and vigour of soybean seed during storage as compared to other oilseed crops and often viability is reduced prior to planting time. Studies on effect of seed invigoration with different antioxidants (Ascorbic acid, α-tocopherol, Butylated Hydroxytoluene) as a mid-storage correction treatment was carried out on four cultivars of soybean viz., JS-335, DS-228 and KDS-726 and Type-49 during 2017-18 and 2018-19 at Seed Technology Research Unit, MPKV, Rahuri. Activities of antioxidative enzyme superoxide dismutase activity and lipid peroxidase activity were studied at initial, 120 and 240 days of storage among four soybean varieties. Seed invigorated with α- tocopherol (200 ppm) and ascorbic acid (100 ppm) significantly enhanced activity of superoxide dismutase (SOD) activity. Wherein, the rate of lipid peroxidase activity was delayed at 240 days of storage as compared to control. Among the varied interactions, the seeds of variety Type 49 invigorated with 200 ppm of α-Tocopherol showed significantly higher superoxide dismutase activity and lower lipid peroxidase activity as compared to other treatments. This summarises that, the 200 ppm of α-Tocopherol invigoration treatment enhances the activity of antioxidative enzyme superoxide dimutase (SOD) and reduces lipid peroxidation during storage. |
