120 mg L−1 chitosan oligomers (COS) effect on chlorophyll content (A) and chlorophyll fluorescence (Fv/Fm) (B) of lemongrass under salinity. Five replicates mean ± standard error is represented for each bar. The difference between the mean values having the same letter(s) is insignificant (p ≤ 0.05) by the LSD test at a 5% probability level (α = 0.05). NaCl concentrations are represented in mM.
