20.500.12556/DKUM-15676 Vpliv nadmorske višine na razvoj ter količino in kakovost pridelka sorte 'Laški rizling' Effect of altitude on the development, yield and quality of 'Welschriesling' V letu 2009 smo v Univerzitetnem centru za vinogradništvo in vinarstvo Meranovo pri sorti 'Laški rizling' proučevali vpliv nadmorske višine (zgornji in spodnji del vinograda) na količino in kakovost pridelka. Proučevan je bil vpliv nadmorske višine na fenološke faze, na temperaturo zraka, grozdov in listov ter na dinamiko dozorevanja grozdja. Opravljena je bila kemična analiza in senzorična ocena vina. Na zgornjem delu vinograda je bila dinamika razvoja fenoloških faz hitrejša za tri dni. Ugotovili smo, da je v našem poskusu nadmorska višina vplivala le na temperaturo grozdov, ki je bila za 1,3 °C višja v zgornjem delu vinograda. Pri spremljanju dinamike dozorevanja grozdja je bila v zgornjem delu vinograda ugotovljena večja vsebnost sladkorja in manj skupnih kislin. V spodnjem delu vinograda je bila enaka vrednost dosežena štiri dni pozneje. Večji pridelek je bil v spodnjem delu vinograda. Pri senzorični oceni vina je bilo bolje ocenjeno vino iz zgornjega dela vinograda. We studied the effect of altitude (upper and lower part of the vineyard) on the development, yield and quality of' 'Welschriesling' in the University Centre for Viniculture and enology Meranovo in 2009. We researched the effect of altitude on phenological phases, air, grapes and leaves temperature and on the dynamics of grape ripening. We did chemical analysis of wine and sensory wine evaluation. On the upper part of the vineyard the dynamic of phenological phases was faster for three days. We found out that in our experiment altitude affected only the grape temperature, which was 1,3 °C higher on the upper part of the vineyard. When we looked at the dynamic of grape maturing we established higher contents of sugar and less of total acidity. On the lower part of the vineyard the same value was reached four days later. Yield was bigger on the lower part of the vineyard. At sensory wine evaluation the wine from upper part of vineyard got better grades. vinska trta nadmorska višina pridelek 'Laški rizling' grapevine altitude yield 'Welschriesling' true true false Slovenski jezik Angleški jezik Diplomsko delo 2010-09-16 15:11:50 2010-10-13 10:39:18 2022-04-13 07:29:49 2023-12-19 03:26:50 2010 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:0OSDBGEA VS_Purgaj_Aleksander_2010.pdf VS_Purgaj_Aleksander_2010.pdf 1 D9884BEE0951117B0F00161C9C28F1B1 cc830d44892ca3688358b5af85326e2e7b9b5e87a186903eb7c88ffd1a065470 747f4a5b-7c04-11eb-bb7a-00155d0001ca 20.500.12556/dkum/4726125c-f37e-4bbb-b45e-f30403fd5350 https://dk.um.si/Dokument.php?lang=slv&id=17334 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
