20.500.12556/RUL-188265 Vpliv razlistanja na kakovost grozdja žlahtne vinske trte (Vitis vinifera) Impact of defoliation on the grape quality of grapevine (Vitis vinifera) Namen diplomskega dela je bil proučiti in primerjati vpliv razlistanja vinske trte na fizikalno-kemijske in senzorične parametre kakovosti grozdja na podlagi analize različnih znanstvenih in strokovnih virov. Uporabili smo metodo deskriptivnega in kritičnega pregleda znanstvene literature. V luči sodobnih klimatskih sprememb se smernice ampelotehničnega ukrepa razlistanja močno spreminjajo. Medtem ko je bil primarni cilj tega ukrepa povečanje sončnega obsevanja grozdov, se danes namen tega ukrepa in njegovi učinki močno razlikujejo glede na termin razlistanja ter sorto vinske trte in lokacijo. Pri pregledu literature smo ugotovili, da imata na termin opravljanja razlistanja zelo močan vpliv sorta in klima. V diplomski nalogi so poudarki na rezultatih raziskav o razlistanju vinske trte na območjih Švice, Hrvaške, Grčije in Avstralije. Ugotovitve so pokazale, da je defoliacija eden od pomembnih ampelotehničnih ukrepov, s katerim lahko vinogradnik neposredno spreminja mikroklimo v coni grozdja, vendar pa njen končni uspeh ni univerzalen, temveč je strogo pogojen s časom izvedbe tega ukrepa, intenzivnostjo ter specifikami posamezne sorte in rastišča. Za vinogradnika je razlistanje pomemben ukrep na vinski trti in mu je potrebno nameniti veliko pozornosti. The aim of this thesis was to investigate and compare the effects of grapevine defoliation on the physicochemical and sensory quality parameters of grapes based on a review of relevant scientific and professional literature. A descriptive and critical review of the scientific literature was conducted. In the context of ongoing climate change, recommendations regarding defoliation as an ampelotechnical practice are undergoing significant change. Whereas the primary objective of defoliation was traditionally to increase solar radiation exposure within the grape cluster zone, its purpose and effects may vary considerably depending on the timing and intensity of defoliation, grapevine cultivar, and site-specific climatic and growing conditions. The literature review demonstrated that both grapevine cultivar and climatic conditions have a major influence on the optimal timing of defoliation. The thesis focuses particularly on research findings concerning grapevine defoliation in Switzerland, Croatia, Greece, and Australia. The results indicate that defoliation is an important ampelotechnical practice that allows grape growers to directly modify the microclimate of the grape cluster zone. However, its overall effectiveness is not universal, and is highly dependent on the timing and intensity of its application, as well as on the specific characteristics of the grapevine cultivar and growing site. Consequently, defoliation represents an important vineyard management practice that requires careful consideration and appropriate adjustment to prevailing climatic conditions, cultivar characteristics, and site-specific conditions. vinska trta Vitis vinifera grozdje razlistanje grapevine vitis vinifera grapes defoliation true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-09-20 07:18:12 2026-09-20 07:18:16 2026-09-23 13:46:00 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 290321 292210435 63562.pdf 63562.pdf 1 644469102F02B1633A455B376D21D3EB 986acc8596e338a520235cdb88f3f03274326e7eb6ca893eb9695f9d76c68528 a3fa686e-b4b2-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=248295 Biotehniška fakulteta 0 0 0
