o:3773 BACTERIAL TREATMENT IMPACT ON MORPHOLOGICAL TRAITS OF ONE-YEAR-OLD SESSILE OAK SEEDLINGS OF TWO SERBIAN PROVENANCES UTICAJ BAKTERIJSKIH TRETMANA NA MORFOLOŠKE OSOBINE JEDNOGODIŠNJIH SADNICA HRASTA KITNJAKA DVE SRPSKE PROVENIJENCIJE en Plant growth promoting bacteria present a diverse group of bacteria with wide applicative potential in seedling production, especially in referring to the Green agenda concept. 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. plant growth promoting bacteria, sessile oak, provenances, morphology, Serbia 1552099 10.5937/SustFor2388079J 1552101 1821-1046 2024-01-16T17:39:30.382Z 44 yes 46 Sanja JOVANOVIĆ 0000-0001-9468-2628 46 Vladan POPOVIĆ 0000-0003-4326-3364 46 Aleksandar LUČIĆ 0000-0002-4473-1791 46 Ljubinko RAKONJAC 0000-0002-8736-6771 application/pdf 279774 https://unilib.phaidrabg.rs/o:3773 no yes 16 70 1552253 Sustainable Forestry: Collection 87-88 79 87 Институт за шумарство, Београд, Србија 2023
