Abstract:
Wheat production is adversely affected by soil salinity due to limited access to irrigation facilities. Effect of soil salinity on four wheat varieties viz. DBW 88, HD 3086, Kharchia 65 and KRL 210 differing in tolerance to salinity have been investigated in the present study. Antioxidant enzymes are crucial in defusing reactive oxygen species (ROS) produced during salinity stress condition. Glutathione reductase (GR) and Glutathione peroxidase (GPx) constitute effective enzymatic anti-oxidant system whose responses are detrimental in imparting stress tolerance. GR activity was linearly increased against increasing salinity in all four wheat varieties studied and more basal increase was observed in tolerant varieties.

Glutathione reductase (GR) and Glutathione peroxidase (GPx) constitute effective enzymatic anti-oxidant system whose responses are detrimental in imparting stress tolerance. GR activity was linearly increased against increasing salinity in all four wheat varieties studied and more basal increase was observed in tolerant varieties.
Higher GPx activities were observed in tolerant varieties and showed slight decreased GPx activities in susceptible wheat varieties under salinity stress. Exogenous application of spermine (Spm) increased the responses of GR and GPx. From our study it was noticed that exogenous spermine application enhances the activities of GR and GPx and provides stress tolerance to wheat crop against salinity induced oxidative stress.
