Figure 1.

The morpho-physiological traits of Svevo and Etrusco cultivars under different conditions: Root (A) and shoot (B) length, root (C) and shoot (D) fresh weight, and relative water content (RWC) in the leaves (E) of two durum wheat cultivars grown under control well-watered (CW), control stressed (CS), mycorrhized watered (MW), and mycorrhized stressed (MS) conditions. Etrusco is represented by white bars and Svevo by black bars. Data are presented as the mean ± SE (n = 5) and significant differences between the Etrusco and Svevo plants (within conditions) are indicated as follows: * p < 0.05. Different letters indicate significant differences between conditions within a genotype (uppercase letters for Etrusco and lowercase letters for Svevo) (Tukey’s test, p < 0.05). An absence of letters means that there were no significant differences between conditions. The two-way ANOVA results are reported in Table S1.
