20.500.12556/RUL-183128 Vpliv termoterapije z vročo vodo na zdravstveno kakovost cepljenk žlahtne vinske trte sorte 'Cabernet sauvignon' Impact of hot water treatment on the health quality of the grapevine grafts of 'Cabernet sauvignon' variety Bolezni lesa vinske trte (BLVT), kamor spada tudi esca, so trenutno ene izmed največjih fitopatoloških izzivov sodobnega vinogradništva, saj povzročajo veliko gospodarsko škodo. Tretiranje z vročo vodo (TT) po standardu EPPO PM 10/18 (1) (za 45 min na 50 °C) je lahko učinkovita metoda za omejevanje širjenja BLVT. Namen magistrskega dela je ugotoviti vpliv TT na kakovost cepljenk žlahtne vinske sorte 'Cabernet sauvignon'. V raziskavo smo vključili cepiče, ki so bili pobrani in razvrščeni glede na bolezenska znamenja matične trte in zdravstveno stanje posameznega cepiča: cepiči s trt brez bolezenskih znamenj BLVT (ZD), cepiči z nekrozami in s trt z bolezenskimi znamenji BLVT (OS) ter cepiči brez nekroz in s trt z bolezenskimi znamenji BLVT (ON) in glede na tretiranji - tretiran po EPPO standardu (TT) in netretirani (NETT). Ugotovili smo, da TT razmnoževalnega materiala, ne glede na zdravstveno stanje cepičev prispeva k večjemu izplenu cepljenk, ta dosega 75 %. Med obravnavanji ne glede na zdravstveno stanje in tretiranje ni bilo značilnih razlik v povprečni masi rozg, številu vseh korenin, številu glavnih korenin in premeru korenin na cepljenko. Na cepljenkah s TT cepiči je bilo značilno več rozg, glede na cepljenke s NETT cepiči. Pri ON. in ZD. cepičih je TT vplivalo na značilno manjšo vsebnost kondenziranih taninov, za 4,4 mg/g SM v primerjavi z NETT. TT je bilo učinkovito pri omejevanju prisotnosti patogenih gliv, kot so Eutypa lata, Phaeoacremonium minimum, Phaeomoniella chlamydospora in Fomitiporia mediterranea. TT razmnoževalnega materiala pred cepljenjem priporočamo za zmanjšanje širjenja BLVT s cepljenkami. Grapevine trunk disease (GTD), including Esca disease, represent a major phytopathological challenges of modern viticulture and they cause an economically damage. Treatment with hot water (TT) according to EPPO PM 10/18 (1) (for 45 min at 50 °C) can be an effective tool for limiting and preventing the spread of BLVT. The aim of the master’s thesis was to determine the impact of TT on the quality of the grapevine grafts of 'Cabernet sauvignon' variety. The study includes scions of varieties that were harvest and sorted based on the GTD symptoms of mother vines and the health status of a scion: scions from vines without GTD symptoms (ZD), scions with necroses from vines with GTD symptoms (OS), and scions without necroses from vines with GTD symptoms (ON), and based on treatments, treated EPPO standard (TT) and untreated (NETT). The results showed that TT significantly increased the yield of grafted plants to an average of 75 %, regardless of the health status of the scions. No significantly differences were observed among treatments, regardless of health status, in the average weight of fruiting canes, number of all roots and of main roots, and in root diameter. A slightly more pronounced difference was shown in the number of canes, especially in ON.TT, where TT contributed to a greater number of canes compared to NETT scions. This may indicate a potentially positive impact of TT on the vegetative development of grafts in plants that are infected but do not yet show visible signs of disease. In ON. and ZD. scions, TT had a significantly reduced content of condensed tannins, 4.4 mg/g DW compared to NETT. TT was effective in limiting the presence of pathogenic fungi, such as Eutypa lata, Phaeoacremonium minimum, Phaeomoniella chlamydospora in Fomitiporia mediterranea. TT of propagation material before grafting is recommended to reduce the spread of BLVT through grafted plants. vinska trta bolezenski kompleks esca tretiranje z vročo vodo bolezni lesa vinske trte grapevine disease complex Esca hot water treatment grapevine trunk disease true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2026-06-05 07:17:25 2026-06-05 07:17:31 2026-06-07 03:25:17 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 279979 280606211 57753.pdf 57753.pdf 1 D1C197512FD885AAEE7FD5E61238E99F df442d88a13a4041077ae06a25db2ce43eff4bbec7e7859482a5a4461c0779cd 7c19c3ef-609d-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=234983 Biotehniška fakulteta 0 0 0
