Table 2.
Concentration of nutrients (% of dry weight) in foliar tissues of lettuce and tomato plants grown for 90 and 100 days, respectively, under 50 mM NaCl (Control) and 150 mM NaCl (Salt-stressed) in the presence (E+) or absence (E−) of root fungal endophytes.
| Species | Nutrient (%) | Control | Salt-stressed | ||
|---|---|---|---|---|---|
| E+ | E− | E+ | E− | ||
| Lettuce | Nitrogen | 3.5 a (±0.16) | 3.1 b (±0.13) | 2.8 c (±0.18) | 2.2 d (±0.22) |
| Phosphorus | 0.7 a (±0.11) | 0.6 a (±0.09) | 0.4 b (±0.11) | 0.3 b (±0.11) | |
| Potassium | 7.1 b (±0.81) | 6.9 b (±1.07) | 10.1 a (±0.54) | 8.2 b (±0.89) | |
| Tomato | Nitrogen | 6.1 a (±0.14) | 5.4 b (±0.17) | 3.6 c (±0.21) | 2.9 d (±0.19) |
| Phosphorus | 0.8 a (±0.11) | 0.7 a (±0.12) | 0.3 b (±0.11) | 0.3 b (±0.09) | |
| Potassium | 9.5 b (±0.33) | 7.8 c (±0.42) | 12.7 a (±0.39) | 11.5 a (±0.41) | |
Values are means ± SD (n = 20). Different lowercase letters indicate significant differences among treatments for each nutrient by species combination (Tukey HSD tests; α = 0.05).
