20.500.12556/DKUM-39896 PROUČEVANJE RAZMNOŽEVANJA GUBAVOLISTNE BROGOVITE (Viburnum rhytidophyllum Hemsl.) S POTAKNJENCI Study of propagation by cuttings of leatherleaf viburnum (Viburnum rhytidophyllum Hemsl.) Raziskava v diplomski nalogi je bila opravljena na gubavolistni brogoviti (Viburnum rhytidophyllum Hemsl.). Namen diplomskega dela je bil proučiti vpliv različnih koncentracij (0,1 %, 0,3 %) rastnega regulatorja indol- 3-maslene kisline (IBA) na ukoreninjenje in morfološke lastnosti ukoreninjenih eno- in dvo-nodijskih potaknjencev v štirih terminih potikanja. Poskus je potekal v rastlinjaku v okolju meglenja. Potaknjence smo narezali na odraslih rastlinah v Botaničnem vrtu v Pivoli. V sredini julija smo uspešno ukoreninili 92 % eno-nodijskih in 95 % dvo-nodijskih, v začetku avgusta pa 89 % eno-nodijskih in 95 % dvo-nodijskih potaknjencev. Tretiranje potaknjencev z rastnim hormonom vpliva na morfološke lastnosti ukoreninjenih potaknjencev. Na osnovi rezultatov ugotavljamo, da je tretiranje potaknjencev z 0,3 % koncentracijo rastnega regulatorja IBA najugodneje vplivalo tako na koreninjenje kot na njihove morfološke lastnosti. Research in diploma thesis was carried out on leatherleaf viburnum (Viburnum rhytidophyllum Hemsl.). The purpose of the thesis was to examine the effect of various concentrations (0,1 %, 0,3 %) of the growth regulator indole-3-butyric acid (IBA) on rooting and morphological properties of the rooted one- and two-node cuttings in four terms planting. The experiment was conducted in a greenhouse under the fog system. The cuttings were acquired from parent plants grown in the Botanical Garden of the University of Maribor in Pivola. In mid-July we have successfully rooted 92 % of one-node and 95 % of two-node cuttings, in the beginning of August, 89 % of the one-node and 95 % of two-node cuttings. Treatment of cuttings with growth regulators affect the morphology of rooted cuttings. On the basis of the results, we conclude that the treatment of cuttings with 0,3 % concentration of the growth regulator indole-3-butyric acid has the most favourable impact both on rooting as to their morphological characteristics. gubavolistna brogovita Viburnum rhytidophyllum Hemsl. vegetativno razmnoževanje potaknjenci rastni regulator Leatherleaf viburnum Viburnum rhytidophyllum Hemsl. vegetative propagation cuttings plant growth regulatos true true false Slovenski jezik Angleški jezik Diplomsko delo 2013-03-14 15:39:09 2013-04-03 14:34:56 2022-05-12 23:17:33 2021-04-22 03:32:49 2013 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:0YU3AMTG VS_Steinfelser_Jozica_2013.pdf VS_Steinfelser_Jozica_2013.pdf 1 38B2054608AE2DD222CB33D60A1A428C b824ed5862ef4778f9257f1fbb7eba4a01835a96bfbdb0ca76960d0c842c165c 3b781605-7c09-11eb-bb7a-00155d0001ca 20.500.12556/dkum/e6cf459a-07f7-4a44-8a27-a5f178e2768b https://dk.um.si/Dokument.php?lang=slv&id=54279 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
