Correction: Guzman, M.R.; Marques, I. Effect of Varied Salinity on Marigold Flowers: Reduced Size and Quantity Despite Enhanced Antioxidant Activity. Agronomy 2023, 13, 3076

In the original publication [1], there was an error in Table 2, as it was mistakenly duplicated from Table 1. Corrected Section 3.3 Paragraph 1 and Table 2 appear below.

3.3. Antioxidative Enzyme Activities

Enzyme activities increased significantly with enhanced levels of salinity, considering CAT (F_3,14 = 8.221; p = 0.0002), POX (F_3,11 = 6.734; p = 0.002), or APX (F_3,16 = 6.356; p = 0.001) (Table 2). The activity of CAT more than doubled with salinity, varying from 11.14 to 23.11 in cv. Aurora Orange, 11.18 to 22.99 in cv. Fireball, and 11.07 to 22.44 in cv. Safari Scarlet (Table 2). In cv. Aurora Orange, CAT activity only increased at the highest salinity levels (100 and 300 mM NaCl), while in the other cultivars, the activity of this enzyme already increased at 50 mM NaCl. The activity of POX also more than doubled with the increase in salinity levels. POX activity varied between 0.31 and 0.69 in cv. Aurora Orange, 0.29 to 0.66 in cv. Fireball, and 0.35 to 0.78 in cv. Safari Scarlet (Table 2). The same trend was recorded for APX activity. A significant variation in the activity of enzymes was found between cultivars, with enzymatic levels usually higher in cv. Safari Scarlet than in the other two cultivars (Table 2). Nevertheless, the highest level of activity was recorded at 300 mM NaCl in all cultivars, considering all enzymes tested.

Table 2. Impact of salinity levels (0, 50, 100, and 300 mM NaCl) on enzyme activities of catalase (CAT), peroxidase (POX), and ascorbate peroxidase (APX), expressed as units/mg of protein DW on the flowers of three Tagetes patula cultivars (cv. Aurora Orange, Fireball, and Safari Scarlet). Results are expressed as mean values ± SE (n = 10). Different superscripts indicate significant differences between salinity levels for the same cultivar (ANOVA followed by a Tukey test at p < 0.05).
