20.500.12556/DKUM-71822 Vpliv aplikacije taninov na pojav skladiščnih bolezni jabolk sort 'Fuji' in 'Pinova' The influence of tannin application on storage diseases of fuji and pinova apples Izvedel se je poljski poskus v nasadih jablan sort 'Pinova' in 'Fuji'. Preučevali smo dva tanin vsebujoča pripravka, katera smo večkrat zaporedoma, v različnih odmerkih nanesli na jablane v obdobju mesec dni pred obiranjem. Uporabili smo odmerke 8 g/drevo, 16 g/drevo ter 32 g/drevo. Pripravka smo nanašali v dvakratnem, trikratnem in petkratnem zaporedju. Največji odmerek tanina je bil 5 × 32 g/drevo, kateri je bil edini apliciran v petkratnem zaporedju. Pripravek Castan® je ekstrakt iz lesa kostanja, pripravek Quertan® je pridobljen iz lesa hrasta. Tretirana jabolka so bila štiri mesece shranjena v hladilnici Evrosad, s kontrolirano atmosfero. Nato smo ugotavljali delež plodov, napadenih z različnimi povzročitelji glivičnih bolezni. Ugotovili smo, da je aplikacija taninov, neodvisno od pripravka, za 10 do 35 % znižala delež plodov, ki so bili v času skladiščenja okuženi z glivami iz rodov Gloeosporium, Penicillium, Botrytis in Monilia. The result of field experiment in the plantations of apple cultivars 'Pinova' and 'Fuji' are presented. We studied two tannin containing preparations, which we repeatedly applied in different doses at several consecutive times to apple trees during the month prior to harvesting. Preparations were used in doses of 8 g/tree, 16 g/tree and 32 g/tree. The Castan® preparation is a chestnut extract and the Quertan® preparation is made of oak wood. Apple samples were stored for four months in the cold store, after which we determined the proportion of fruits affected by various agents of fungal diseases. The application of tannins reduced the proportion of fruits that were infected from fungi of the genera, Gloeosporium, Penicillium, Botrytis, Monilia at the time of storage between 10 to 35 %. tanini hrast kostanj skladiščne bolezni zatiranje jabolka tannins oak chestnut storage diseases control apple true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2018-08-31 08:10:30 2018-09-10 14:57:08 2022-08-01 21:29:24 2019-07-11 18:55:51 2018 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:XABPP24D UN_Gricnik_Nasja_2018.pdf UN_Gricnik_Nasja_2018.pdf 1 C9E6A8B43FE29BF46334431AB0A661F6 1873c0ce71a6f78b80373638da0d7d9de07dc1fb31a3cefe95b56acc9d0c0ef0 3f4209fe-7c10-11eb-bb7a-00155d0001ca 20.500.12556/dkum/681ca0ed-dced-44b7-8b26-825332821646 https://dk.um.si/Dokument.php?lang=slv&id=128551 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
