The plant growth-promoting bacterium Kosakonia radicincitans improves fruit yield and quality of Solanum lycopersicum

  • BACKGROUNDProduction and the quality of tomato fruits have a strong economic relevance. Microorganisms such as the plant growth-promoting bacterium (PGPB) Kosakonia radicincitans (DSM 16656) have been demonstrated to improve shoot and root growth of young tomato plants, but data on yield increase and fruit quality by K. radicincitans are lacking. RESULTSThis study investigated how K. radicincitans affects tomato fruits. After inoculation of tomato seeds with K. radicincitans or a sodium chloride buffer control solution, stalk length, first flowering and the amount of ripened fruits produced by inoculated and non-inoculated plants were monitored over a period of 21 weeks. Inoculation of tomato seeds with K. radicincitans accelerated flowering and ripening of tomato fruits. Sugars, acidity, amino acids, volatile organic compounds and carotenoids in the fruits were also analyzed. CONCLUSIONIt was found that the PGPBK. radicincitans affected the amino acid, sugar and volatile composition of ripened fruits, contributing to a moreBACKGROUNDProduction and the quality of tomato fruits have a strong economic relevance.
