20.500.12556/DKUM-58314 VPLIV KONCENTRACIJE RASTNEGA REGULATORJA NA UKORENINJENJE POTAKNJENCEV SIBIRSKE SVIBE (Cornus alba 'Sibirica') V POLETNO - JESENSKEM OBDOBJU Influence of concentration of growth regulators on rooting cuttings of siberian svib (Cornus alba 'Sibirica') in summer-autumn period Raziskava v diplomski nalogi je bila opravljena na Sibirski svibi (Cornus alba 'Sibirica'). V okviru raziskave smo proučili vpliv rastnega regulatorja indol-3-maslene kisline (IBA) na koreninjenje in morfološke lastnosti ukoreninjenih potaknjencev. Dvo-nodijske potaknjence smo potikali v petih terminih v poletno-jesenskem obdobju in jih tretirali s štirimi koncentracijami IBA (0 %, 0.1 %, 0.3 %, 0.5 %). Potaknjence smo rezali iz matične rastline, ki raste v Botaničnem vrtu Univerze v Mariboru. Ugotovili smo, da rastni regulator IBA ne vpliva na uspeh koreninjenja potaknjencev. Potaknjenci so se najbolje ukoreninili v drugi dekadi avgusta.. V tem terminu so se netretirani potaknjenci in tisti, ki smo jih tretirali z rastnim regulatorjem IBA v koncentraciji 0,3 % ukoreninili 100 %. Pri analizi morfoloških značilnosti ukoreninjenih potaknjencev ugotavljamo, da so potaknjenci tretirani z rastnim regulatorjem IBA tvorili signifikantno večje število korenin daljših od 2 mm. The reserch in this thesis was performed on Siberian Svib (Cornus alba 'Sibirica'). The research examined the impact of plant growth regulator indol-3-butyric acid (IBA) on rooting and morphological properties of rooted cuttings. Two-nodus cuttings were prowling five times in the sumer-autumn period and were treated with four concentrations of IBA (0%, 0.1%, 0.3%, 0.5%). They were cut from mother plant, which grow in University of Maribor in Botanic Garden. We found, that growth regulator IBA does not affect on the success of rootting cuttings. Cuttings rooted best in second decade of august. In this period not treated cuttings, and those that were treated with growth regulator IBA in concentration of 0,3 % rooted 100 %. By analyzing the morphological characteristics of rooted cuttings we found, that those cuttings that were treated with growth regulators IBA formed significantly more roots wich were longer than 2 mm.
