20.500.12556/RUL-188277 Tehnološki ukrepi za blaženje sušnega in vročinskega stresa pri vinski trti Technological measures for mitigating drought and heat stress in grapevine Podnebne spremembe povečujejo tveganje za sušni in vročinski stres pri vinski trti v slovenskih vinorodnih deželah. Diplomsko delo s pregledom strokovne in znanstvene literature predstavi fiziološke in biokemične odzive trte na sušo in vročino ter tehnološke ukrepe za blaženje njunih posledic. Najboljše rezultate omogoča celostni pristop, ki se začne ob zasnovi vinograda: izbira lege, nadmorske višine, ekspozicije ter sorte in podlage. Najbolj primerne so gojitvene oblike z manjšo transpiracijsko površino in večjim senčenjem grozdov. Zastiranje tal zmanjša izhlapevanje vode, nizko košena medvrstna ozelenitev pa omeji konkurenco za vodo v medvrstnem prostoru. Zelena dela je treba prilagoditi trenutnim razmeram, kjer moramo biti pozorni na oba stresorja. Proti vročinskem stresu pomaga mehanska zaščita (mreže, folije) in antitranspiranti ter biostimulanti. Kapljično namakanje ter namakanje na podlagi sezonskega spremljanja vlažnosti tal zmanjšata porabo vode brez izgube kakovosti pridelka. Climate change is increasing the risk of drought and heat stress in grapevines in Slovenian wine-grown regions. This thesis reviews scientific literature on the physiological and biochemical responses of grapevine to drough and heat stress, as well as viticultural practices for mitigating their effects. The most effective strategy is an integrated approach that begins with vineyard establishment, including the selection of site, altitude, aspect, cultivar and rootstock. Training systems with a smaller transpiring surface and greater bunch shading are the most suitable. Soil mulching reduces water evaporation, while maintaining a low-mown cover crop limits competition for water in the inter-row area. Canopy management practices should be adapted to current conditions, taking both stress factors into account. Under heat stress, mechanical shading such as shade nets and foils, as well as antitranspirants and biostimulants, can help reduce damage. Drip irrigation and irrigation based on seasonal monitoring of soil moisture can reduce water use without compromising crop quality. vinska trta sušni stres vročinski stres tehnološki ukrepi vinograd prilagajanje podnebnim spremembam grapevine drought stress heat stress technological measures vineyard climate change adaptation true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-09-20 07:19:11 2026-09-20 07:19:13 2026-09-24 14:07:36 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 290327 292398083 63172.pdf 63172.pdf 1 E3B623AC85DFD37D40EB24E87E2EDA84 1a69420b7306170cd02761668a29f4b131c00fefeb250c2632894bdc44741cc3 c3ea8ab5-b4b2-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=248307 Biotehniška fakulteta 0 0 0
