Values are mean ± standard error of the mean for bioassays conducted in triplicate. Means followed by the same letter(s) for the two incubation regimes are not significantly different (multivariate analysis, Fisher’s Protected LSD at ).
XAP: Xanthomonas axonopodis pv. Phaseolicola; XAM: Xanthomonas axonopodis pv. Manihotis; and PSP: Pseudomonas savastanoi pv. Phaseolicola.
