20.500.12556/DKUM-16507 PREIZKUŠANJE NEKATERIH NOVIH SORT VINSKE TRTE ODPORNIH NA GLIVIČNE BOLEZNI Testing some of new grape varieties resistant to fungal diseases V letu 2008 smo na Univerzitetnem centru za vinogradništvo in vinarstvo Meranovo v vinogradu, ki je bil posajen spomladi leta 2006, preizkušali nove sorte (medvrstne križance) vinske trte, ki so odporne na nekatere glivične bolezni. Poskus je obsegal 7 sort: 'Muškat bleu', 'Monarch', 'Prior', 'Rondo', 'Cabernet Carol', 'Regent' in 'Phoenix'. Spremljali smo fenofaze, pojav pomembnejših glivičnih bolezni in po trgatvi opravili mikrovinifikacijo. Pri statistični obdelavi podatkov smo ugotovili, da sta bili v fazah razvoja najzgodnejši sorti 'Muscat bleu' in 'Modri pinot' (kontrolna sorta), najpoznejša pa sorta 'Prior'. Največja gostota mošta je bila pri sorti 'Regent' (96 °Oe), najmanjša pa pri sorti 'Prior' (62 °Oe). Grozdje sorte ''Muscat bleu' je bilo zelo osipano. Zelo močna okužba s peronosporo na zalistnikih je bila pri sorti ''Phoenix', sorta 'Muscat bleu' pa je bila brez okužb. Pri nobeni sorti ni bilo znamenj okužb z oidijem. Na dan trgatve je bilo največ gnilobe pri sorti 'Phoenix' in 'Rondo'. Pri ostalih sortah ni bilo prisotne gnilobe In 2008, in the vineyard of The University of Agriculture Center Meranovo, which was planted in spring 2006, we studied new grape varieties (inter-variety crossbreeds) which are resistant to some fungal diseases. We investigated seven grape varieties: 'Muscat bleu', 'Monarch', 'Prior', 'Rondo', 'Cabernet Carol', 'Regent' and 'Phoenix'. We were observing the phenophases and fungal disease attacks, and after harvesting we carried out microvinification. Statistical evaluation of data showed that growth stages were earlier in 'Muscat bleu' and Pinot Noir' (control varieties) than in 'Prior'. The highest density of must was observed in 'Regent' (96 °Oe), and the lowest in 'Prior' (62 °Oe). Substantial cluster shedding occurred in ''Muscat bleu'. We observed a severe attack of downy mildew on the lateral shoots of 'Phoenix', while 'Muscat bleu' was without any infections. There was no sign of powdery mildew on any grape variety. On harvesting day grape Botrytis cinerea infection was observed in 'Phoenix' and 'Rondo', whereas other varieties were not infected. vinska trta / odpornost / glivične bolezni / fenofaze OP: VI 34 s. 22 graf. 24 ref. vine / resistivity / fungus diseases / phenophases NO: VI 34 P. 22 Graph 22 Ref. true true false Slovenski jezik Angleški jezik Diplomsko delo 2010-10-24 16:33:17 2010-11-03 11:50:22 2022-04-13 08:13:24 2023-12-20 03:36:41 2010 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:GJBKA9TN VS_Fras_Suzana_2010.pdf VS_Fras_Suzana_2010.pdf 1 59598A19B0425E494C73A07CEE54399D 987d8a0fab01b5e2570dfb67c63dd7b453ce61e01eed73924af7d41660b7cd49 a9a68152-7c04-11eb-bb7a-00155d0001ca 20.500.12556/dkum/1acc63eb-e272-4b7a-b1c1-25614c35da73 https://dk.um.si/Dokument.php?lang=slv&id=18765 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
