20.500.12556/DKUM-39641 Razmnoževanje navadnega pušpana (Buxus sempervirens L.) s potaknjenci v poletno- jesenskem obdobju Propagation of boxwood (Buxus sempervirens L.) with cuttings during summer and autumn period Razmnoževanje navadnega pušpana (Buxus sempervirens L.) s potaknjenci v poletno- jesenskem obdobju Raziskava v diplomski nalogi je bila opravljena na visoko rastočem navadnem pušpanu (Buxus sempervirens var. arborescens) in na nizko rastoči sorti 'Suffruticosa'. V raziskavi smo proučevali vpliv termina rezanja potaknjencev, vpliv tipa potaknjenca in vlogo rastnih regulatorjev na ukoreninjenje potaknjencev. Potaknjence smo rezali iz rastlin, rastočih na prostem, v Botaničnem vrtu Univerze v Mariboru in v parku pod Kalvarijo v Mariboru. Visoko rastoč navadni pušpan uspešno razmnožujemo v sredini avgusta. V tem terminu se je ukoreninilo 88% potaknjencev. Najprimernejši čas za razmnoževanja nizkega pušpana je od sredine julija do sredine avgusta. V tem obdobju je bil odstotek ukoreninjenja med 97% in 100%. Tip potaknjenca ni vplival na uspešnost koreninjenja. Tretiranje potaknjencev z rastnim regulatorjem vpliva na odstotek ukoreninjenih potaknjencev. Rezultati raziskave nakazujejo, da je optimalna koncentracija rastnega regulatorja odvisna od stopnje zrelosti potaknjenca. Propagation of boxwood (Buxus sempervirens L.) with cuttings during summer and autumn period The graduation thesis research was performed on the tall-growing boxwood (Buxus sempervirens var. arborescens) and on its low-growing variety 'Suffruticosa'. The research investigated the influence of the date the cuttings are cut, the influence of the type of cutting and the role of growth regulators on the rooting of cuttings. The cuttings were cut from outdoor-growing plants in the Botanical Garden of the University of Maribor and in the park under Kalvarija in Maribor. Tall-growing boxwood can be successfully propagated in the middle of August. At this time, 88% of cuttings rooted. The most suitable period for propagating low-growing boxwood is from the middle of July to the middle of August. During this period, the percentage of rooting was between 97% and 100%. The type of cutting has no impact on the success of rooting. Treatment of cuttings with a growth regulator affects the percentage of rooted cuttings. The results of the study indicate that the optimum concentration of the growth regulator depends on the level of maturity of the cutting. navadni pušpan Buxus sempervirens L. vegetativno razmnoževanje potaknjenci rastni regulator boxwood Buxus sempervirens L. vegetative propagation cuttings growth regulator true true false Slovenski jezik Angleški jezik Diplomsko delo 2013-02-12 01:29:11 2013-03-01 14:02:50 2022-05-12 23:06:36 2021-04-22 03:27:31 2013 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:EBIG26MY VS_Bozic_Martina_2013.pdf VS_Bozic_Martina_2013.pdf 1 CB18AC47A1CD286D3D06D46EA53F6A9D 38f684ae9e182bcbab7395c03791a44329a72ddd51881ba651d3f4278c7a2772 2ccd3f6a-7c09-11eb-bb7a-00155d0001ca 20.500.12556/dkum/095c7732-714c-41e1-a280-a9935435d629 https://dk.um.si/Dokument.php?lang=slv&id=53721 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
