The effects of UV solar exclusion on the POD, CAT, SOD and APX activities and GSH content in P. vulgaris leaves

Antioxidant system	Control	UV solar exclusion
POD activity (U mg−1 proteins)	78.48 ± 3.31 b	112.73 ± 21.37 a
CAT activity (U mg−1 proteins)	38.09 ± 7.22 b	53.06 ± 7.28 a
SOD activity (U mg−1 proteins)	49.12 ± 9.36 a	53.91 ± 14.11 a
APX activity (U mg−1 proteins)	0.62 ± 0.10 a	0.80 ± 0.07 a
GSH content (mg g−1 proteins)	95.79 ± 4.21 a	90.39 ± 1.68 a

Each value is presented as the mean ± SD (n = 3). Different letters in lines indicate a significant difference at p < 0.05
