Carotenoid concentrations in leaves of highbush blueberry cultivars under Al toxicity. Carotenoid concentrations and violaxanthin/anteraxanthin ratio in control (0 μM Al) and aluminum (200 μM Al) treatments in cultivars Brigitta, Star, Duke, Camellia, and Cargo at 24 and 48 h. The values are the average of three measurements per cultivar and treatment. Due to a lack of differences among time points in treatments without Al, we considered the values at 0 h as the average among the start of the experiment and the respective controls for each time point (24 and 48 h). Bars represent standard error among replicates. For details and statistical differences, see Supplementary Table 1).
