20.500.12556/DKUM-42386 Ugotavljanje fitotoksičnosti bakra pri cepljenkah sorte 'Sauvignon' na podlagah 'Kober 5BB' in 'SO4' Determination of copper fitotoxicity by grafted vines cv. 'Sauvignon' on the rootstocks 'Kober 5BB' and 'SO4' V letu 2011 smo v Trsničarstvu Mantet, v Čadramu, v lončnem poskusu v kontroliranih razmerah (rastlinjaku) ugotavljali fitotoksičnost bakra pri sorti 'Sauvignon', cepljeni na podlagi 'Kober 5BB' in 'SO4'. V substrat smo dodali različne količine bakra (50, 150, 500 in 1000 mg Cu/kg substrata). Baker je bil dodan v dveh oblikah, in sicer kot Cu-oksiklorid (Cuprablau-Z; tradicionalni fungicid) in Cu-glukonat (Labicuper; sistemično foliarno gnojilo). Pri cepljenkah smo spremljali dinamiko rasti mladik, pojav fititoksičnosti in analizirali vsebnost bakra v rozgah, podlagi in koreninah. Ugotovili smo, da se vsebnost bakra v koreninah in v podlagi povečuje z večjo vsebnostjo bakra v tleh ter da je podlaga 'SO4' manj tolerantna na visoke vsebnosti bakra v tleh kot podlaga 'Kober 5BB', saj je pri 1000 mg Cu/kg tal pri podlagi 'SO4' propadlo več cepljenk. Glede na uporabljen pripravek je več cepljenk propadlo pri pripravku Labicuper. In the year 2011, an experiment was conducted in Čadram at Trsničarstvo Mantet. Experiment was placed under the controlled conditions (in glasshouse). We used potted grapevine cv. 'Sauvignon', grafted on two rootstocks, 'Kober 5BB' and 'SO4'. In the substrate, we added four concentration of copper (50, 150, 500 and 1000 mg Cu/kg substrate). Copper was added in two different formulations, as Cu-oxychloride (Cuprablau-Z; traditionally used fungicide) and Cu-gluconat (Labicuper: systemic foliar fertilizer). For one growing season, we monitored growth dynamics, fitotoxicity and analyze copper content in roots and shoots after the experiment was completed. We found out that the content of cooper in roots depends on cooper content in soil and that rootstock 'SO4' does not tolerate as high concentration of cooper in substrate as rootstock 'Kober 5BB'. At highest content of copper in the substrate, more grafted grapevines have failed on rootstock 'SO4'. Based on the product we used, more grafted grapevines have failed at Labicuper. vinska trta/baker/fitotoksičnost/'Kober 5BB'/'SO4' grapevine/cooper/fitotoxicity/'Kober 5BB'/'SO4' true true false Slovenski jezik Angleški jezik Diplomsko delo 2013-09-18 23:35:37 2013-10-11 11:28:43 2022-05-07 03:06:38 2021-04-26 03:33:15 2013 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:0QHIRANJ VS_Leskovar_Mojca_2013.pdf VS_Leskovar_Mojca_2013.pdf 1 C7022BBB82E5255F17F2F2D2019B51E3 65b5bbc5df5b4bbec2be83cc8271c45578964b4a9db0f838fd03086d4c17ff26 630e2746-7c0a-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=59225 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
