Figure 4. Root-knot nematodes reproduction on tomato is affected by the Nr mutation in compatible host only.

Figure 4

Root-knot nematodes (RKN) reproduction was evaluated on Never ripe (Nr) mutant, wild type tomato cvs. Pearson and VFN, and the Nr introgressed line VFNxNr. Four-week-old plants were infected with 3,000 second-stage juvenile RKN. (A) Egg masses and (B) eggs production were evaluated 6 weeks after RKN infection. Results are presented relative to the fresh weight (FW) of roots. Error bars indicate standard error of the mean (n = 20–30), where bars with different letters denote significant difference at P<0.05. Two independent experiments were performed with similar results and data from one are presented.
