| Gamma irradiation (Gy) | Control | 30 | 60 | 90 | 120 |
|---|---|---|---|---|---|
| Chlorophyll a (μg/g FW) | 15.86b ± 0.24 | 19.45a ± 1.01 | 18.04a ± 0.64 | 17.74a ± 1.14 | 16.59ab ± 1.06 |
| Chlorophyll b (μg/g FW) | 10.54b ± 0.33 | 12.65a ± 0.94 | 13.66a ± 1.06 | 12.68a ± 0.92 | 11.13ab ± 0.71 |
| Carotenoid (mg/g FW) | 1.59b ± 0.07 | 2.22a ± 0.08 | 2.19a ± 0.05 | 2.14a ± 0.05 | 1.84b ± 0.03 |
| Anthocyanin (mMol/g FW) | 14.8a ± 0.86 | 14.5a ± 0.96 | 10.6b ± 0.85 | 10.9b ± 1.07 | 7.88c ± 0.72 |
The means of the samples with the same small letters were not significantly different as per Duncan's multirange test at P < 0.05.
