| BHT | 9.30 ± 1.13 b | 45.77 ± 1.45 a | 426.73 ± 0.81 a |
| C1 | 40.83 ± 4.16 a | 21.83 ± 2.21 b | 391.77 ± 6.46 c |
| C2 | 2.50 ± 2.06 c | 2.50 ± 0.20 d | 387.57 ± 4.42 cd |
| C3 | 6.92 ± 6.64 b | 7.52 ± 0.80 c | 401.80 ± 1.71 b |
| C4 | 3.54 ± 3.07 c | 3.36 ± 0.30 d | 384.27 ± 1.12 cd |
| C5 | 2.81 ± 2.17 c | 3.23 ± 0.30 d | 381.10 ± 1.57 d |
Values are means ± SD (standard deviation). Values with similar letters in a column are not significantly different; (p < 0.05) according to Tukey’s post hoc test.
