Biomics

The dry biomass of plants and the content of pigments in the leaves of tomato cultivar Gruntovy Gribovskiy 1180 were analyzed 30 days after inoculation with growth-stimulating bacterial strains Pseudomonas sp. 2.4.1 and Stenotrophomonas sp. 2.13. It was revealed that the Pseudomonas sp. 2.4.1 strain stimulated the accumulation of plant biomass more efficiently than Stenotrophomonas sp. 2.13, which positively correlated with an increase in the content of chlorophyll and carotenoids in tomato leaves. Thus, the content of pigments in plants can serve as a marker of the effectiveness of associative symbiosis between tomato plants and various microorganisms.
