20.500.12556/DKUM-21938 Vpliv koncentracije rastnega regulatorja na ukoreninjenje potaknjencev metličaste hortenzije (Hydrangea paniculata Siebold) The influence of plant growth regulator concentrations on rooting of paniclade hydrangea (Hydrangea paniculata Siebold) cuttings Proučevali smo vpliv koncentracije rastnega regulatorja Seradix (0,1%; 0,3%; 0,8% indol-3-maslena kislina=IBA) na ukoreninjenje in morfološke lastnosti ukoreninjenih eno- in dvo-nodijskih potaknjencev metličaste hortenzije (Hydrangea paniculata Siebold) v šestih terminih potikanja od julija do oktobra. Potaknjence smo odvzeli iz štiri leta starih rastlin gojenih v loncih na prostem pri rastlinjaku Fakultete za kmetijstvo in biosistemske vede v Pivoli. V začetku julija smo uspešno ukoreninili 89% eno-nodijskih in 85% dvo-nodijskih, v septembru pa 91% eno-nodijskih in 87% dvo-nodijskih potaknjencev. Tretiranje potaknjencev z rastnim regulatorjem vpliva na morfološke lastnosti ukoreninjenih potaknjencev. Pri eno-nodijskih potaknjencih, ki smo jih tretirali z rastnim regulatorjem IBA v koncentraciji 0,8% se je število korenin v prvem terminu potikanja povečalo za 50% in v četrtem za 28% v primerjavi s kontrolo. Pri dvo-nodijskih potaknjencih je bila optimalna koncentracija rastnega regulatorja IBA med 0,3% in 0,8%. We studied the effect of concentration Seradix growth regulators (0.1%, 0.3%, 0.8% indole-3-butyric acid = IBA) on rooting and morphology of rooted one-and two-node cuttings hydrangea paniclade (Hydrangea paniculata Siebold ) six terms planting from July to October. Cuttings were taken from four-year-old plants grown in pots outdoors in a greenhouse at the Faculty of Agriculture and Life Sciences in Pivola. In early July, we have successfully embedded 89% one-node and 85% two-node cuttings, in September 91% single and 87% two node cuttings. Treatment of cuttings with growth regulators affect the morphology of rooted cuttings. In one-node cuttings that were treated with growth regulators IBA at a concentration of 0.8%, the number of roots in the first period increased by 50% and the fourth by 28% compared to control. In two-node cuttings was node optimal growth regulator IBA concentration between 0.3% and 0.8%. hortenzija Hydrangea paniculata Siebold vegetativno razmnoževanje potaknjenci rastni regulator hydrangeas Hydrangea paniculata Siebold vegetative propagation cuttings growth regulator true true false Slovenski jezik Angleški jezik Diplomsko delo 2012-01-23 16:50:19 2012-01-31 10:49:24 2022-04-14 11:01:19 2023-12-29 03:22:04 2012 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:NPVMUPLX VS_Gobec_Anita_2012.pdf VS_Gobec_Anita_2012.pdf 1 9233128E00AABE6B8A33368E13EA82F2 8e9f9c4bfc4041ca8500e47f55a38ffbcd2e75fe75e54f392756ff4d027244be f858b12a-7c05-11eb-bb7a-00155d0001ca 20.500.12556/dkum/76332f27-ee71-4e59-86fd-a165c248b51d https://dk.um.si/Dokument.php?lang=slv&id=28070 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
