(a) Total chlorophyll (ChlTOT), and (b) total carotenoid (CarTOT) content in leaves of the durum wheat cultivars Emilio Lepido (solid) and Svevo (pattern) subjected to 0 (i.e., control; white), 14 (i.e., WL14; light gray), or 35 (i.e., WL35; dark gray) days of waterlogging (DOW). Data are mean ± standard deviation. FW: fresh weight. For each waterlogging duration, according to Tukey’s post hoc test (p ≤ 0.05), different letters indicate significant differences among means (p ≤ 0.05).
