(a-d) Gas analysis parameters (a) Photosynthetic rate; (b) Conductance; (c) Carbon intake; (d) Transpiration rate in M. incognita inoculated 60 days old tomato plants under treatment with S. hydrogenans strain DH-16. Different treatments are represented as C (control), NI (nematode inoculated), CC (culture cells), CC + NI (culture cells + nematode inoculated), S (supernatant), S + NI (supernatant + nematode inoculated), E (crude extract), E + NI (crude extract + nematode inoculated). Results are given in mean ± standard error and F-value ** indicates significance at p ≤ 0.01 and ns indicates non-significant difference as per Tukey’s test. Different letters a, b, c, d represent significant difference among treatments and same letters represent no significant difference.
