The activity of mitochondrial enzymes which coordinate the mitochondrial redox system (Succinate dehydrogenase, NADH dehydrogenase, NADH oxidase and ATPase) were investigated against salt exposure. The increased activity of all mitochondrial enzymes in leaves of strawberry were observed up 0.75 % NaCl concentration, which probably explains the survival of the strawberry plant at this concentration.. The higher concentration of NaCl, (above the 0.75 % NaCl concentrations) affected the growth towards reduction and finally caused death of strawberry plants at 3 % NaCl concentration. The efficient mitochondrial redox system was exhibited by chandler variety of strawberry at 0.75 % NaCl concentration. Specific activity of succinate dehydrogenase, NADH dehydrogenase and NADH oxidase showed the highest rate of redox reaction at 0.75 % NaCl concentration, and ATPase also showed the maximum oxidative phosphorylation at 0.75 % NaCl concentration. Mitochondrial enzymes studied to understand the response to NaCl induced stress was exhibited better performance at 0.75 % NaCl concentration in strawberry and this may probably suggest the redox system operated by mitochondria was efficient in the development of resistance against NaCl oxidative stress. So these mitochondrial enzymes may be used as tools for the improvement of resistance against the salinity stress by genetic engineering experiments i.e. transgenic plant development. The toxicity developed was appears to be probably due to the suppressed activity of mitochondrial enzymes and antioxidants.This also suggests that the minor saline soils may possibly adapt to the strawberry variety chandler as a cultivar at farmer level.
