The content of apigenin, naringenin, pisatin, dibutyl- ortho -phthalate, and N -phenyl-2-naphthylamine were assayed in root exudates of pea ( Pisum sativum L.) seedlings one day after their inoculation with Rhizobium leguminosarum bv. viceae or Pseudomonas siringae pv. pisi , which represent, respectively, mutualistic and antagonistic strategies of interaction with a host plant. After inoculation with either bacteria, the concentrations of apigenin and pisatin in the root exudates were equal, whereas the concentrations of naringenin and N -phenyl- 2-naphthylamine were different and those of dibutyl- o -phthalate were unchanged. A certain role is suggested for the phenolic compounds in an accomplishment of symbiotic relations of bacteria with a host plant.
