20.500.12556/DKUM-47749-150853b9-6a05-26fd-39d2-fbe81bc39e0f VPLIV RASTNIH REGULATORJEV NA UKORENINJENJE POTAKNJENCEV TISE (Taxus x media 'Hicksii') V JESENSKO ZIMSKEM OBDOBJU THE INFLUENCE OF PLANT GROWTH REGULATORS ON ROOTING OF YEW 'HICKSII' (Taxus x media 'Hicksii') IN AUTUMN-WINTER PERIOD Raziskavo smo opravili na stebrasti tisi (T. × media 'Hicksii'), ki je križanec med navadno tiso (T. baccata L.) in japonsko tiso (T. cuspidata Seib. Et Zucc.). Namen diplomskega dela je bil preučiti vpliv tretiranja potaknjencev z različnimi koncentracijami indol-3-maslene kisline (0 %, 0,5 % in 1 %) na ukoreninjenje in morfološke lastnosti ukoreninjenih potaknjencev v različnih terminih potikanja. Potaknjence smo narezali iz matičnih rastlin, rastočih na Botaničnem vrtu Univerze v Mariboru, v štirih terminih. Ugotovili smo, da termin potikanja vpliva na uspeh koreninjenja potaknjencev. Pri potaknjencih, ki smo jih potikali v januarju smo dosegli 98 % ukoreninjenost. Dodajanje avksinskih rastnih regulatorjev vpliva na morfološke značilnosti potaknjencev. Povprečna sveža masa potaknjenca in povprečna sveža masa korenin sta bili statistično značilno večji v vseh terminih potikanja, če smo jih tretirali z rastnim regulatorjem IBA 0,5 % in 1 % v koncentraciji. Our research was conducted on Hicks yew (T. × media 'Hicksii') ), which is hybrid between common yew (T. baccata L.) and Japanese yew (T. cuspidata Seib. Et Zucc.). The main objective of the research was to study the impact of treatment of cuttings with three different concentrations (0 %, 0,5 % and 1 %) of indole-3-butyric acid (IBA) on rooting and morphological properties of rooted cuttings during the autumn-winter period. Cuttings were obtained from the stock plants grown in Maribor Botanical Garden at four dates. We found that the term of planting have impact on the success of rootedness. Cuttings that we planted in January have achived 98 % rootedness. Adding of auxin growth regulator has an impact on morphological properties of rooted cuttings. Average fresh weight of the cuttings and the average fresh weight of the roots were significantly higher in all dates of use IBA growth regulators in concentrations 0,5 % and 1 %. stebrasta tisa Taxus × media 'Hicksii' vegetativno razmnoževanje potaknjenci rastni regulator pillared yew Taxus × media 'Hicksii' vegetative propagation cuttings growth regulator true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2015-04-02 10:58:53 2015-04-17 13:27:31 2022-05-22 03:08:12 2021-05-07 03:33:32 2015 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:XZK7J9YO VS_Regvart_Danijela_2015.pdf VS_Regvart_Danijela_2015.pdf 1 13AE2BA4DEC933C59848705CFC3CA449 aeae5aaed8c9580ec9db7a29f4c43e1c43db8389cfb4f92762a2bc026567a838 ed5eee41-7c07-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=71061 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
