| Treatment * | Shoot Length (cm) | Root Length (cm) | Shoot Dry Weight (g) | Root Dry Weight (g) | No. of Leaves | Leaf Area (cm2) |
|---|---|---|---|---|---|---|
| C | 26.3 ± 0.6 b | 16.7 ± 0.5 b | 0.42 ± 0.03 b | 0.26 ± 0.02 b | 7.0 ± 0.2 a | 12.81 ± 0.3 b |
| M | 33.0 ± 1.1 a | 19.3 ± 0.7 a | 0.52 ± 0.09 a | 0.34 ± 0.06 a | 7.6 ± 0.4 a | 17.07 ± 0.2 a |
| P | 21.7 ± 1.0 c | 11.3 ± 0.9 c | 0.32 ± 0.02 c | 0.15 ± 0.09 c | 6.0 ± 0.3 a | 9.24 ± 0.2 c |
| M+P | 35.3 ± 1.0 a | 18.7 ± 0.3 a | 0.55 ± 0.05 a | 0.31 ± 0.08 a | 7.6 ± 0.5 a | 16.93 ± 0.1 a |
C = untreated control, M = colonized with R. irregularis, P = infected with R. solani, M+P = colonized with R. irregularis and infected with R. solani. * Values of each column followed by the same letter are not significantly different according to Tukey’s HSD test (p ≤ 0.05), each value represents the mean of four replicates ± SD.
