Use of a bacterial composition comprising at least one plant growth-promoting bacterium from the Microbacterium genus, for producing biostimulant effects in seeds, seedlings and/or plants, comprising the step of priming said seeds, or seedlings or plants. The bacterial composition particularly comprises Microbacterium strains EC8 and/or all strains sharing >98% nucleotide sequence homology with EC8 at the 16S rRNA gene level (in particular strains EC19 and W283), and/or strains EC6, W211, W236, W219 and W269.. The bacterial composition is particularly applied to a plant growth medium, for instance before seedling transplantation. Very good biostimulant effects have been obtained for lettuce, tomato and basil plants. |
