a Protein content (mg g−1 FW), b total free amino acids (mg g−1 FW), c proline (mg g−1 FW) of P. vulgaris L. after foliar application of different concentration of acetylsalicylic acid (ASA; 0, 0.1, 0.5, 1, 2, 3 mM) and exposed to different level of chilling stress (0, 2, 4 days). Data represented are mean of two replicates ± standard deviation. Variations between different chilling stresses and foliar ASA concentration were assessed by univariate analyses followed by post hoc analysis. Means with the same letters are not significantly different according to Duncan’s multiple comparisons
