| dc.description.abstract | The present study aimed at evaluating the antioxidant potential of barley and oat forage crops (RD-2552 and OL-9 respectively) under normal field conditions at 30, 60 and 90 days after sowing and of grains of barley genotypes viz. RD-2552, PL-172, PL-807, PL-426, DWRUB- 52 and VJM-201 and oat genotypes viz. 0L-9, 0S-6, OS-7, HJ-8 and HF0-114. The antioxidant potential was estimated in terms of activities of antioxidant enzymes viz. superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), glutathione reductase (GR) and peroxidase (POD) and ascorbic acid (Vit.C) content. Contents of hydrogen peroxide (H2O2) and malondialdehyde (MDA) were also estimated. Antioxidant enzymes activities and Vit.C registered maximum value at 60 DAS in both the crop leaves. The values were significantly (CD 5%) higher in barley as compared to oat leaves at all the three vegetative stages. H2O2 content was minimum at 60 DAS whereas MDA content was lowest at 30 DAS in both the crop leaves. The levels were however significantly (CD 5%) lower in barley as compared to oat leaves. Among different barley grains PL-172, RD-2552, PL-807 and DWRUB-52 had higher and VJM-201 and PL-426 lower antioxidant enzyme activities and Vit.C content. There seemed to be no association between two rowed and six rowed barley genotypes and antioxidant enzyme activities. H2O2 content was lowest in PL- 807 and highest in VJM-201. MDA content was undetected in PL-172 and highest in VJM- 201. In oats OL-9, OS-6 and OS-7 grains had high antioxidant enzyme activities and Vit.C content whereas HJ-8 and HFO-114 grains registered lower values. However these genotypes had higher H2O2 and MDA levels. The study depicts that barley crop and grains inherently have higher antioxidant potential as compared to oat crop and grains. | en_US |
