Table 5 Relative water content (RWC) and maximum efficiency of PSII photochemistry (Fv/Fm ratio, indicative of damage to PSII) in Rosmarinus officinalis leaves of control and salt-stressed plants (treated with 200 mM NaCl for 8 days).
RWC (%) | Fv/Fm | |
|---|---|---|
Control young leaves | 80.83 ± 1.63a | 0.837 ± 0.02a |
Control old leaves | 83.09 ± 1.57a | 0.837 ± 0.01a |
Stress young leaves | 73.83 ± 1.78b | 0.728 ± 0.03b |
Stress old leaves | 61.32 ± 1.10c | 0.633 ± 0.04b |
