20.500.12556/DKUM-71416 Kompatibilnost različnih podlag vinske trte s sorto 'Renski rizling' in pojav nodozitet na koreninah, okuženih s trtno ušjo (Daktulosphaira vitifoliae Fitch) Compatibility of Various Grapevine Rootstocks with the ’Riesling’ Variety and the Emergence of Nodosities on Phylloxera (Daktulosphaira vitifoliae Fitch) Infected Roots V lončnem poskusu v rastlinjaku smo v letih 2014 in 2015 ugotavljali pojav nodozitet in trtne uši na koreninah različnih kombinacij (podlaga/cepič) Vitis L. ('Renski rizling', 'Johanniter', '5C'). Korenine vseh cepljenih kombinacij smo vsako leto v juniju inficirali s trtno ušjo (100 jajčec na lonček). Vsako leto, na koncu rastne dobe, pet mesecev po infekciji, smo pod optičnim mikroskopom prešteli primerke trtne uši v posameznih razvojnih fazah in nodozitete. Ugotavljali smo še kompatibilnost 14 različnih podlag s sorto 'Renski rizling'. Podlagi ’Alhäros’ in ’Novo Mexicana’ v naših razmerah nista bili kompatibilni s sorto 'Renski rizling' (propadle so vse cepljenke), pri ostalih kombinacijah pa je bil izplen nad 50 %. Največ nodozitet je bilo na koreninah podlage '5C', kar je bilo v nasprotju s pričakovanji. Najmanj nodozitet in osebkov trtne uši se je pojavilo pri kombinaciji cepiča '5C', cepljenega na sorto 'Renski rizling'. Število nodozitet na koreninah ni vplivalo na maso suhe snovi korenin in rozg (R²=0,0226). In 2014 and 2015 we conducted an experiment under controlled conditions (in a glasshouse), with potted grapevines. We determined the appearance of nodosities and phylloxera on the roots of different combinations (rootstock/scion) of Vitis L. ('Riesling', 'Johanniter', '5C'). Roots of all combinations were infested in June of every year (100 eggs per pot). At the end of the growing season in both years, five months after infection, we examined the roots under a microscope and counted the phyloxera and the nodosities. Simultaneously, we evaluated the compatibility of the 'Riesling' variety, grafted on 14 different rootstocks. Our findings suggest that two of them (’Alhäros’ and ’Novo Mexicana’) are not compatible with 'Riesling' in our conditions (all the grafts have failed), on the other hand, graft success of the other combinations was good (more than 50%). The appearance of nodosities and phylloxera was the greatest on grapevines grafted on rootstock ‘5C’, which we did not expect. The least nodosities or phylloxera were found where ‘5C’ was grafted on 'Riesling' rootstock. The number of phylloxera per root system did not affect the dry weight of the roots and shoots (R²=0.0226). vinska trta trtna uš podlage kompatibilnost 'Renski rizling' grapevine phylloxera rootstocks compatibility 'Riesling' true true false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2018-08-10 20:40:56 2018-09-10 13:09:43 2022-08-01 20:52:42 2019-07-11 18:39:46 2018 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:XQ0IFJRN MAG_Gumzej_Mojca_2018.pdf MAG_Gumzej_Mojca_2018.pdf 1 2645E627FDAB12AD6857072D6D3FC399 56f8667d06dc5fa3de139426c1e384947e8c8b2395b802360a05f2879cf504fe 3cb9022b-7c10-11eb-bb7a-00155d0001ca 20.500.12556/dkum/90cdd88e-4600-48f2-82b1-a44bf0a35479 https://dk.um.si/Dokument.php?lang=slv&id=128400 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
