The effect of the bacteria Rhizobium and Pseudomonas on total content of phenolic compounds (PC) and their individual components (apigenin, naringenin, dibutyl-ortho-phthalate, pisatin, N-phenyl-2-naphthylamine) in the root exudates of the pea seedlings (Pisum sativum L. ) at two different growth stages was studied . Bacteria have similar affect on the total number of PC and the number of constituent apigenine, phthalate and pisatine. Difference at the impact of these bacteria on the content of naringenin and N-phenyl-2-naphthylamine was detected, which can be attributed to the peculiarities of the interactions of plants of peas with bacteria-antagonists and mutualists.

Key words: Rhizobium, Pseudomonas, Pisum sativum L., seedling, plant-microbe interaction, root exudates, phenolic compounds
