FIGURE 4.
Capability of Bacillus firmus I-1582 to induce systemic resistance in tomato cv. Durinta and cucumber cv. Dasher II against Meloidogyne incognita in two split root experiments. The inducer part of the root was inoculated with 109 CFU of B. firmus I-1582 and the responder part of the root was inoculated with 200 J2 of M. incognita. In the responder part of the root the number of egg masses per plant (infectivity) and the number of eggs per plant (reproduction) were assessed 43 days after nematode inoculation. Number of egg masses per plant (A–C) and total nematode eggs per plant (D–F). Tomato experiment 1 (A,D); tomato experiment 2 (B,E); cucumber experiment (C,F). Data are means ± standard error of 10 replicates. The asterisk indicates within each graph and for each experiment, that treatments are significantly different (P < 0.05) according to the non-parametric Wilcoxon test.
