20.500.12556/DKUM-64486 UGOTAVLJANJE FENOLOŠKIH FAZ IN TEHNOLOŠKIH LASTNOSTI NEKATERIH ODPORNIH NAMIZNIH SORT VINSKE TRTE DETERMINATION OF PHENOLOGICAL STAGES AND TEHNOLOGICAL PROPERTIES OF SOME RESISTANT TABLE GRAPE VARIETIES V letu 2014 smo na Univerzitetnem centru za vinogradništvo in vinarstvo Meranovo spremljali faze razvoja nekaterih odpornih sort namiznega grozdja. Spremljali smo, koliko dni je preteklo pri posamezni sorti od brstenja (BBCH 05) do tehnološke zrelosti (BBCH 89). Tehnološko zrelost grozdja smo določili z analizo vsebnosti sladkorja (od 65 do 75 °Oe) in s senzorično oceno zrelosti. Faza brstenja je najprej (21. marca) nastopila pri sorti 'Einset seedless', najpozneje (7. aprila) pa pri sortah 'Sophie', 'Angela' in 'Schuyler'. Glede na trajanje vegetacije (od brstenja do tehnološke zrelosti) smo v skupino zgodnjih sort (130‒145 dni) uvrstili sorte 'Xenia' ,'Reflex', 'Prima', 'Black Magic', 'Kyoho' , 'Clara' in 'Vierul 59'. V skupino srednje poznih sort (146‒165 dni) smo uvrstili sorte 'Prezentabil', 'Patrizia', 'Primus', 'Galant', 'Karmen', 'Sophie', 'Einset seedless', 'Angela' in 'Schuyler'. Med pozne sorte (165 dni in več) smo uvrstili sorte 'Muscat blue', 'Ontario', 'Terez' in 'Guzun'. Pri senzoričnem ocenjevanju smo ugotovili, da je bila jagodna kožica najbolj moteča pri sorti 'Schuyler', najmanj pa pri sorti 'Black Magic'. Semena so bila najbolj moteča pri sorti 'Muscat blue', najmanj pa pri sortah 'Einset seedless', 'Black Magic' in 'Evita'. Največ ocenjevalcev bi kupilo sorte 'Prima', 'Evita' in 'Primus', skoraj nihče pa ne bi kupil sorte 'Guzun'. In 2014, we monitored the development stages of some resistant table grape varieties at the University Centre for Viticulture and Oenology Meranovo. For each variety we monitored how many days had passed from the wool stage (BBCH 05) to the stage when the berries are ripe for harvest (BBCH 89). The stage when the berries are ripe for harvest was determined by sugar content analysis (from 65 to 75 °Oe) and by sensory evaluation of ripeness. The wool stage appeared first (21 March) for the 'Einset seedless’ variety and last (7 April) for the 'Sophie', 'Angela' and 'Schuyler' varieties. According to the vegetation length (from wool stage to the “berries are ripe for harvest” stage) 'Xenia', 'Reflex', 'Prima', 'Black Magic', 'Kyoho', 'Clara' and 'Vierul 59' were placed in the group of early varieties (130 to 145 days). 'Prezentabil', 'Patrizia', 'Primus', 'Galant', 'Karmen', 'Sophie', 'Einset Seedless', 'Angela' and 'Schuyler' were placed in the group of medium late varieties (146 to 165 days). 'Muscat Blue', 'Ontario', 'Terez' and 'Guzun' were placed in the group of late varieties (165 days and more). Sensory evaluation showed that the grape skin was most disruptive in the 'Schuyler' variety and the least in the 'Black Magic' variety. Seeds were most disruptive in the 'Muscat Blue' variety, and the least in the 'Einset Seedless', 'Black Magic' and 'Evita' varieties. Most evaluators would buy the 'Prima', 'Evita' and 'Primus' varieties, and almost no-one would buy the 'Guzun' variety vinska trta fenofaze odporne namizne sorte tehnološke lastnosti grape vine phenophases resistant table grape varieties technological properties. true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2016-10-07 13:56:34 2016-10-11 07:12:05 2022-07-05 03:07:55 2019-07-11 14:03:23 2016 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:4CXPXCY1 VS_Bracko_Urska_2016.pdf VS_Bracko_Urska_2016.pdf 1 233348905929AB1D6F20864B43D41475 6d4a50ffa7daa57ed87b7acc7625b6df9621ac12820d592b9a9ef3176c3869d7 c5c61970-7c0d-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=107468 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
