Significant differences in the same row are indicated with different lowercase letters (comparison among the 13 cultivars investigated in this study at the same crop season, p < 0.05) and with different capital letters (comparison between crop seasons for the same cultivar, p < 0.05). Since only the quantitative results for some of the determined compounds are included in Table 2 for 9 varieties (to contain the size of the table), the results shown herewith were considered together with those from Table 4 to carry out ANOVA analysis. Secoiridoids were quantified in terms of Oleuropein. P-Languedoc: Picholine de Languedoc.
