Table 5.

Relative water content (RWC) and maximum efficiency of PSII photochemistry (F_v/F_mratio, indicative of damage to PSII) in Rosmarinus officinalis leaves of control and salt-stressed plants (treated with 200 mM NaCl for 8 days).

	RWC (%)	F_v/F_m
Control young leaves	80.83 ± 1.63^a	0.837 ± 0.02^a
Control old leaves	83.09 ± 1.57^a	0.837 ± 0.01^a
Stress young leaves	73.83 ± 1.78^b	0.728 ± 0.03^b
Stress old leaves	61.32 ± 1.10^c	0.633 ± 0.04^b
