| Water condition | EBR (nM) | Chl a (mg g−1 FM) | Chl b (mg g−1 FM) | Total Chl (mg g−1 FM) | Car (mg g−1 FM) |
|---|---|---|---|---|---|
| Control | 0 | 7.33 ± 0.37Ba | 1.71 ± 0.05Ca | 9.04 ± 0.48Ba | 0.78 ± 0.06Aa |

Chl a Chlorophyll a; Chl b Chlorophyll b; Total Chl Total chlorophyll; Car Carotenoids. Columns with different uppercase letters between EBR levels (0, 50 and 100 nM EBR under equal water condition) and lowercase letters between water conditions (control and water deficit under equal EBR concentration) indicate significant differences from the Scott–Knott test (P < 0.05). Values described corresponding to means from five repetitions and standard deviations
