The effect of pure volatiles, i.e., methyl isovalerate (MIV) and 2-undecanone (2-UDE), on antioxidant enzymes. (a–d) Activity in M. incognita-infested and non-infested tomato plant roots. The root samples of different treatments were taken at 4 dpi to obtain enzyme extract. Error bar represents the mean standard deviation of three repeats with three replicates for each treatment. The small letters above the columns indicate significant difference. The significant difference among the treatments was calculated through Tukey’s HSD test at p ≤ 0.05.
