Root colonization (a), leaf area (b), shoot dry mass (c), and root dry mass (d) of cowpea plants irrigated with saline water and inoculated with dark septate endophytic fungi. NI = without inoculation; 21W2 = roots inoculated with strain 21W2; and B’2 = roots inoculated with strain B’2. Fig. 3a: bars with the same letter do not differ by Tukey’s test (p < 0.01), n = 3. Fig. 3 b, c, and d: *significant differences by Tukey’s test (p < 0.05), n = 10
