Data are shown as mean ± SD (n = 10). Control and treatment group data were compared with each other and there was a statistically significant difference between the values indicated with * sign (p < 0.05), there was no significant difference between the values indicated with ** sign (p > 0.05). MDA: malondialdehyde, Prl: proline, SOD: superoxide dismutase, Chl: chlorophyll, CAT: catalase.
