The effect of colonization by beneficial associative microorganisms Pseudomonas putida KT 2442 and Rhodococcus erythropolis X5 on the growth of Sarepta mustard (Brassica juncea L.) under a covering light-converting material containing organic photoluminophore, in vitro and in vivo, was investigated. The combined use of microbial colonization and photoluminophore coating led to stimulation of plant growth much stronger (2.4 times more) than separately only photoluminophoric coating (1.3 times) or colonization (2.1 times). These data indicate that when covering materials with photoluminophores are used in agrobiotechnologies, luminescent red light (610-730 nm) induces an increase in biochemical processes not only in plants, but also in microorganisms that supply plants with growth regulators and other useful metabolites. The data obtained are relevant for further study of the photobiological mechanisms of interactions between the plant-microorganism system in agrobiotechnologies.
