Bacterial strains promote the growth of peach, sweet cherry and plum saplings in the regions with the short growing season

The research was done to consider the regulating potential of 3 plants growth-promoting bacterial (PGPB) strains, including Burkholderia gladia BA7, Bacillus subtilus OSU142, and Bacillus megatorium M3 alone and their combinations on the growth of grafted peach, sweet cherry, and plum nursery plants in 2014, which had not sufficient growth after grafting in the first year (2013) at the Abant Izzet Baysal University, Bolu, Turkiye. The results found that the two combinations of isolates are more efficient than their three combinations or using them alone. The most efficient treatment was observed OSU142 + M3 in the case of peach, OSU142 + BA7 in the sweet cherry, and M3+BA7 in the plum. In conclusion, changes in climate situations and increasing in the world population need extraordinary attempts to increase plant materials in an organic and sustainable way. Bacterial strains are among the bioregulators that have emerged as promising, new, and environmentally friendly microorganisms to support the overall sustainability of production systems. Briefly, bacterial applications significantly affected many growth characteristics of peach, sweet cherry, plum, and other fruit crops. So, they would be advised for the organic production of saplings.
