Nematode population (reproduction) of Meloidogyne species: M. incognita, M. javanica, M. chitwoodi in the roots of tomato plants. Initial nematode number (first infection number) was 1000 nematode in each pot for each plant. Final nematode number was calculated following the 2 months later of nematode inoculation. Randomised block design was accomplished with five repetitions. Y axis represents final nematode number per plant, X axis indicates nematode species. Error bars represents the standard error of the means of five replicates. Letters on the column indicates the statistical differences (P < 0.05) among nematode populations
