|---|---|---|---|---|
| Specific activity (U/mg protein) | Relative activity (%)∗ | Specific activity (U/mg protein) | Relative activity (%)∗ | |
| 0 | 0.389 ± 0.05B | 100.000 ± 12.078B | 0.892 ± 0.102A | 100.000 ± 11.422A |
| 0.05 | 0.490 ± 0.02A | 125.966 ± 5.020A | 1.112 ± 0.037A | 127.715 ± 4.204A |

| 1.00 | 0.147 ± 0.01C | 37.807 ± 2.982C | 0.466 ± 0.043B | 48.778 ± 4.869B |
| 2.00 | 0.116 ± 0.02C | 29.822 ± 5.124C | 0.139 ± 0.037C | 15.177 ± 5.843C |
#Data in the table are expressed by mean ± SD, n = 6. Data followed by different superscript capital letter within same column means significant difference at P = 0.01 level. ∗Relative activity of AHAS was determined as the percentage of absorbance value of each sample of TBM-treated plants and the corresponding sample of the control plants (treated with 0 mg⋅L-1 of TBM).
