20.500.12556/DKUM-22047 Vpliv koncentracije rastnega regulatorja na ukoreninjanje potaknjencev Purpusovega kosteničevja (Lonicera × purpusii Rehder.) v poletnem obdobju The influence of plant growth regulator concentration on rooting of Lonicera × purpusii Rehder. Shrubby honeysuckle in summer Eksperiment smo opravili na Purpusovem kosteničevju (Lonicera x purpusii Rehder.), ki je križanec med Lonicera fragrantissima in Lonicera standishii. Namen diplomskega dela je bil proučiti vpliv različnih koncentracij (0,8 %, 0,3 %, 0,1 %, 0 %) rastnega regulatorja indol-3-maslene kisline na ukoreninjenje in morfološke lastnosti potaknjencev v rastlinjaku v poletnem obdobju, v okolju meglenja. Potaknjence smo narezali na odraslih rastlinah v Botaničnem vrtu v Pivoli. Potikali smo dvo-nodijske zelene in pol-olesenele potaknjence. Potaknjenci Purpusovega kosteničevja so najbolje koreninili julija do konca avgusta, ko smo dosegli nad 97 % ukoreninjenost. Dodajanje avksinskega pripravka pred potikanjem ni povečalo števila ukoreninjenih potaknjencev. Optimalna koncentracija rastnega regulatorja je odvisna od stopnje olesenelosti lesa potaknjenca in se spreminja glede na termin potikanja in glede na opazovane morfološke lastnosti. Na podlagi rezultatov poskusa ugotavljamo, da je tretiranje potaknjencev z 0,1 % koncentracijo rastnega regulatorja indol-3-maslene kisline najugodneje vplivalo tako na koreninjenje kot na njihove morfološke lastnosti. Our experiment was conducted on Lonicera × purpusii Rehder. Shrubby honeysuckle which is a hybrid between Lonicera fragrantissima and Lonicera standishii. The aim of our graduation was to examine the influence of different concentrations of indole-3-butyric acid (0.8 %, 0.3 %, 0.1 %, 0 %) plant growth regulator on rooting and the morphological characteristics of the cuttings in a greenhouse fogging system in summer. The cuttings were acquired from parent plants grown in the Botanical Garden of the University of Maribor in Pivola. We planted two-node green and half-lignified cuttings. Shrubby honeysuckle cuttings rooted best from July to the end of August when the rooting exceeded 97%. Adding auxin before planting the cuttings did not increase the number of rooted cuttings, but from the statistical point of view, it influences significantly the morphological characteristics of the rooted cuttings. The optimum concentration of the plant growth regulator depends on the cutting's degree of lignification and varies according to the planting period and the observed morphological characteristics. The obtained results show that the treatment of cuttings with a 0.1 % indole-3-butyric acid had the most positive influence both on the rooting and the morphological characteristics.
