20.500.12556/DKUM-98529 Proučevanje razmnoževanja fotinije (Photinia × fraseri 'Red Robin') s potaknjenci magistrsko delo A study on photinia (photinia × fraseri 'red robin') propagation from cuttings Raziskava v magistrskem delu je bila opravljena v letu 2024 in 2025 na 720 potaknjencih Fraserjeve fotinije (Photinia × fraseri 'Red Robin'). Namen magistrskega dela je bil proučiti razmnoževanje fotinije na vegetativni način z vršnimi in dvonodijskimi potaknjenci. Proučevali smo vpliv različnih koncentracij (0 %, 0,25 % in 0,8 %) rastnega regulatorja IBA na koreninjenje in morfološke lastnosti ukoreninjenih potaknjencev. Vršne in dvonodijske potaknjence smo potikali v petih terminih. Termin 1 (28. 6. 2024) se je izkazal kot najboljši termin za ukoreninjenje potaknjencev, saj se jih je ukoreninilo 85,4 %. Ugotovili smo, da sta imela termin potikanja in tip potaknjenca statistično značilen vpliv na ukoreninjenje potaknjencev. Na podlagi rezultatov lahko trdimo, da se vršni potaknjenci koreninijo uspešnejše kot dvonodijski potaknjenci, in da se potaknjenci, tretirani z rastnim regulatorjem v koncentraciji 0,8 % bolje ukoreninijo kot potaknjenci v kontroli. The research for the master’s thesis was conducted in 2024 and 2025 on 720 cuttings of Fraser’s photinia (Photinia × fraseri 'Red Robin'). The aim of the thesis was to investigate the vegetative propagation of photinia using apical and two-node cuttings. We examined the effects of different concentrations (0 %, 0,25 %, and 0,8 %) of the growth regulator IBA on rooting success and the morphological characteristics of rooted cuttings. Apical and two - node cuttings were rooted at five different times. The first term (June 28, 2024) proved to be the most successful, with 85,4 % of the cuttings rooting. Our results showed that both the rooting time and the type of cutting had a statistically significant effect on rooting success. Based on the findings, we conclude that apical cuttings root more successfully than two - node cuttings, and that cuttings treated with a growth regulator at a concentration of 0,8 % exhibit better growth than untreated (control) cuttings. fotinija Photinia × fraseri 'Red Robin' razmnoževanje potaknjenci rastlinski rastni regulatorji Photinia Photinia × fraseri 'Red Robin' propagation cuttings plant growth regulators true true false S.
