Fig 2. The effect of exogenous spermine (Spm) on (A) relative water content (RWC), (B) electrolyte leakage (EL) and (C) malondialdehyde (MDA) content in leaves of white clover under drought stress.

Vertical bars indicate ±SE of mean (n = 4). Different letters above columns indicate significant difference for comparison at a given day; the same number of asterisks above columns means significant differences for a particular treatment across days of drought stress don’t exist. LSD (P≤0.05). L, cv. ‘Ladino’; L+Spm, cv. ‘Ladino’ added exogenous Spm; H, cv. ‘Haifa’, H+Spm, cv. ‘Haifa’ added exogenous Spm.
