Abstract:
V letu 2010/2011 smo v rastlinjaku in laboratoriju za genetiko Fakultete za kmetijstvo in biosistemske vede preučevali razmnoževanje izbranih vrst javorjev. Pri vegetativnem razmnoževanju smo ugotavljali vpliv termina potikanja in rastnega regulatorja (0,8 % indol-3-maslena kislina IBA) na ukoreninjenost potaknjencev in razvoj kalusa srebrastega javorja (Acer saccharinum L.) in dveh sort pahljačastega javorja (Acer palmatum L. 'Atropurpureum' in 'Bloodgood'). Pri generativnem razmnoževanju smo ugotavljali vpliv različnih načinov stratifikacije na delež vzkaljenih semen pahljačastega javorja (Acer palmatum 'Thunberg ex Murray'). Poskus s potaknjenci je potekal v rastlinjaku v okolju megljenja in je bil zasnovan v štirih terminih. Termin potikanja ima statistično značilen vpliv na ukoreninjenost potaknjencev. Zgodnejši termini (v začetku poletja) so primernejši za razmnoževanje. Tretiranje potaknjencev z rastnim regulatorjem IBA v koncentraciji 0,8 %, vpliva na uspešnost koreninjenja potaknjencev. Na osnovi rezultatov ugotavljamo, da so potaknjenci srebrastega javorja v sredini junija dosegli 89 % razvoj kalusa in konec julija 97 % ukoreninjenje. Najvišji vznik sejancev (89 %) smo določili 36 dni po setvi, nenamočenega stratificiranega semena, ki je bil 30 dni izpostavljen rastni komori in 120 dni stratifikaciji (4 °C).

Title:
PROPAGATION PF SELECTED MAPLES SPECIES WIZH SEEDS AND CUTTINGS
Abstract:
In 2010 and 2011 a maple tree propagation experiment was carried out in a greenhouse and a laboratory of the Faculty of Agriculture and Life Sciences in Maribor. In vegetative propagation research the focus was on the influence of the time of potting-on and on the influence of the growth regulator (0,8 % Indole-3-butyric acid IBA) on rooting and on callus development of silver maple Acer saccharinum L. and two species of Acer palmatum L. (Atropurpureum and Bloodgood). In generative propagation research the focus was on the influence of different kinds of stratification on germination percentage of seeds of Acer palmatum Thunberg ex Murray. The cuttings experiment was carried out in four time series in the greenhouse using fog system. Time of the potting-on has statistically significant influence on rooting of cuttings. Early terms (at the beginning of the summer) are more appropriate for propagation. Cuttings treatment with the growth regulator IBA (0,8 % solution) influences on cuttings rooting. The results showed that silver maple cuttings reached 89 % callus development in the middle of June and 97 % rooting at the end of July. The best germination rate (89 %) of the unsoaked stratified seeds exposed to 30 days of the growth room and 120 days of stratification (4 °C) was set for 36th day after the seeding.
