Fig 3. Effects of root exudates on corrected mortality of M. incognita J2.

HR, MR and T represent the root exudates from three tomato strains: Baliya (highly resistant), RS2 (moderately resistant) and L-402 (highly susceptible), respectively. The mortality of J2 in each root exudate (sterilized water as control) was assessed by the eyelash needle stimulus method at 24 h and 48 h after starting the assay. Corrected mortality rate (%) = (mortality rate of J2 in root exudate—mortality rate of J2 in sterilized water) / (1—mortality rate of J2 in sterilized water) ×100. Each bar represents the mean, and error bars indicate standard error of the mean from three replicates. Capital and lower case letters indicate significant group differences at the levels of 0.01 and 0.05, respectively.
