comparison to controls particularly at the 140 mm concentration of nacl the composition of the present invention enhanced sod activity particularly at the highest concentrations similarly see fig1 the present composition at 1200 and 1800 u03bcl l u2212 1 enhanced cat activity at 9 weeks following application of 35 mm nacl catalase is important because it eliminates h 2 o 2 produced by sod the present composition at 600 and 1200 u03bcl l u2212 1 enhanced cat activity at 9 weeks following application of 70 mm nacl application of the present composition at 1800 u03bcl l u2212 1 enhanced cat activity at 9 weeks following application of 140 mm nacl to levels greater than the control group similarly the composition of the present invention enhanced ap which together with monodehydroascorbate reductase dehydroascorbate reductase and glutathione reductase aid in removing h 2 o see foyer and halliwell 1976 and gr activity in salt stressed tomato plants in particular see fig1 ap activity in plants exposed to 35 and 70 mm nacl was increased by application of the present composition the observed increase was greatest in plants exposed to 140 mm nacl and 1200 and 1800 u03bcl l u2212 1 of the present composition reaching an activity level greater than the control group the composition of the present invention 600 and 1200 u03bcl l u2212 1 see fig1 also increased gr activity particularly in tomato plant leaves exposed to 35 and 70 mm malondialdehyde a measure of lipid peroxidation in.
