Effects of exogenous methyl jasmonic acid (MeJA) on phenotypic changes (A), relative water content (RWC) (B), electrolyte leakage (EL) (C), malondialdehyde (MDA) content (D), total chlorophyll content (E), chlorophyll a content (F), and chlorophyll b content (G) of perennial ryegrass after heat stress. Vertical bars indicate ± SE of the mean (n = 5). No common letter above bar indicates a significant difference by least significant difference (LSD) (P < 0.05). CK, control check; CK + MeJA, control check was pretreated with 100 μmol/L of MeJA; H, heat stress; H + MeJA, heat-stressed plants pretreated with 100 μmol/L of MeJA.
