Opis (eng)

"The root rhizosphere is one of the densest habitats on the planet, where significant intimate interactions between plants and their recruited rhizomicrobiota are implemented. Plant genetics impacts community composition. However, this communication is a two-way process regarding microorganisms modulating plants's physiological processes as well, which are eventually manifested in plant vigor, growth, and development. One-year-old sessile oak seedlings of provenances Đerdap and Goč were treated with Bacillus sp. (treatment 1) and Pseudomonas sp. (treatment 2) in order to study their effect on the enhancement of seedling growth. Sessile oak seedlings were monitored for one growing season in semicontrolled conditions in the nursery of the Institute of Forestry. At the end of the experiment, seedling height and root collar diameter were measured by a ruler and Vernier's caliper as the standard morphological parameters of seedling growth. The obtained data were analyzed statistically in GraphPad Prism, and ANOVA and Dunnett's test were applied. The results indicate the enhancement of seedlings' growth treated with bacteria. Seedlings of Đerdap provenance treated with treatment 1 were 35% higher, and the ones treated with treatment 2 were 32% higher compared to the control. Seedlings of Goč provenance treated with treatment 1 were 85% higher than control. The effect of bacterial treatments on seedling root collar diameter of both provenances was not statistically significant, although it enhanced their mean values. The obtained results indicate the potential of bacterial treatments to increase seedling growth, which should be researched comprehensively in the future, especially in the context of biological fertilizer commercialization."
