The effect of 2 bacterial species on one-year-old sessile oak seedling’s height, root collar diameter, and their ratio was studied. Oak plants were from 2 provenances – Avala and Košutnjak. The most significant influence on measured traits in Avala had treatment with Pseudomonas koreensis, and in Košutnjak, with Viridibacillus arvi. However, a two-way analysis of variance showed no statistical significance of provenance effect and bacterial treatment on measured traits. The research needs to be repeated on a greater number of individuals in order to confirm the results since the bacteria manifested their PGP potential in vitro.
