Methyl salicylate (MeSA) is a signal molecule in plant responses to biotic and abiotic stress and elicits plant resistance against chilling injury. An experiment was conducted to determine whether MeSA applied at 0, 0.25, 0.5, and 0.75 mM as a seed soak or foliar application would protect cucumber (Cucumis sativus L.) seedlings subjected to chilling at 3°C for 5 days. The MeSA improved growth rate of cucumber seedlings and increased relative leaf chlorophyll and relative water contents by inhibiting malondialdehyde and H2O2 accumulation and increasing proline and antioxidant capacity. MeSA was most effective when applied using the seed soak method at 0.5 and 0.75 mM.
