Peroxidase and Superoxide Dismutase EnzymeActivities in Sulphur Applicated Chickpea (Cicer arietinum L.) Grown under Rainfed Condition

Abstract

Five varieties of chickpea alongwith three different doses of sulphur such as S0, S15 and S30 kg/ha in the form of gypsum were grown at Agriculture Farm, Rajoula, Chitrakoot, Satna, M.P. under rainfed conditions for studies of enzyme activities at vegetative stage (fresh leaf samples) and reproductive stage (fresh seed samples). The enzyme activity such as peroxidase (POX) in vegetative and reproductive stages ranged from 25.26 to 32.27 and 20.56 to 26.20 U/min/g/fresh wt, respectively. Superoxide dismutase (SOD) enzyme activity in vegetative and reproductive stages ranged from 13.51 to 26.13 and 21.21 to 30.13 Unit g/f.wt, respectively. The maximum peroxidase enzyme activity was found in vegetative stage alongwith application of 30 kg/ha of sulphur as compared to vegetative stage, whereas the maximum SOD activity was recorded in reproductive stage as compared to vegetative stage alongwith application of 30 kg/ha of sulphur.
