20.500.12556/DKUM-64281 POMEN ČASA IN NAČINA REZI ZA VZPOSTAVITEV FITZIOLOŠKEGA RAVNOTEŽJA PRI JABLANI GOJITVENE OBLIKE ZELO VITKO VRETENO The importance of timing and method of pruning to establish physiological balance by apple with training form ultra slim spidle V dvoletnem poskusu (2006–2007) smo na lokaciji Blanca in Loka pri Zidanem Mostu spremljali vpliv časa in jakosti rezi na jablani (Malus domestica B.) sort 'Zlati delišes' in 'Braeburn'. V poskus je bilo vključenih 8 različnih kombinacij rezi (v nadaljevanju obravnavanj): 1 – standardna zimska rez, 2 – standardna zimska rez + junijska rez, 3 – standardna zimska rez + rez po obiranju, 4 – standardna zimska rez + junijska rez + rez po obiranju, 5 – delna zimska rez, 6 – delna zimska rez + junijska rez, 7 – delna zimska rez + rez po obiranju, 8 – delna zimska rez + junijska rez + rez po obiranju. Ugotavljamo, da se je pri izvajanju rezi manjše intenzivnosti pri obravnavanju 8 najbolj povečal prirast debel, kar je imelo za posledico tudi večji volumen dreves na sorti 'Zlati delišes'. Jakost rezi je bila v pozitivni korelaciji z vsebnostjo suhe snovi pri sorti 'Zlati delišes' v obeh letih poskusa (2006–2007) ter z večjo maso in trdoto mesa plodov v letu 2006. Potrdilo se je, da so standardna zimska rez in njene kombinacije najbolj primeren način rezi za doseganje primernega pridelka visoke kakovosti na sorti 'Zlati delišes'. Na sorti 'Braeburn' ugotavljamo, da se je pri izvajanju rezi manjše intenzivnosti pri obravnavanjih 5, 6, 7 najbolj povečal prirast debel, tudi tu je bila posledica večji volumen dreves. Na sorti 'Braeburn' je jakost rezi bila v pozitivni korelaciji z maso posameznega ploda, suho snovjo, sočnostjo, trdoto mesa plodov in titracijsko kislino, izražena kot jabolčna v prvem letu poskusa (2006), v drugem letu (2007) pa je bila v pozitivni korelaciji samo z maso ploda (statistično značilne razlike). Potrdilo se je, da so standardna zimska rez in njene kombinacije najbolj primeren način rezi za doseganje primernega pridelka visoke kakovosti pri omenjen sorti. In a two-year experiment (2006–2007) on locations Blanca and Loka at Zidani Most, the effects of timing and intensity of pruning apple (Malus domestica B.) of the varieties 'Golden Delicious' and 'Braeburn', were observed. The experiment involved 8 different combinations of pruning: 1 – dormant winter pruning, 2 - dormant winter pruning + June pruning, 3 - dormant winter pruning + pruning after harvesting, 4 - dormant winter pruning + June pruning + pruning after harvesting, 5 - partial winter pruning, 6 - partial winter pruning + June pruning , 7 - partial winter pruning + pruning after harvesting, 8 partial winter pruning + June pruning + pruning after harvesting. It has been established that the implementing of lower intensity pruning especially at combination 8 increased the growth of the trunk, consequently increasing the volume of tree varietiy 'Golden Delicious'. With the variety 'Golden Delicious', higher intensity of pruning has resulted in increased dry matter content in a fruit in both years of the experiment (2006–2007) and in increased weight and increased hardness in 2006. With the variety 'Braeburn', it has been observed, that the pruning intensity at combinations 5, 6, 7 had influence on the weight of the apple fruit, dry matter, juiciness, hardness and malic acid in a fruit in the first year of the experiment (2006), whereas in the second year (2007), only the effect on the weight of the fruit was observed, while other observed parameters, did not prove statistically significant. It was confirmed that at both varieties 'Golden Delicious' and 'Braeburn', the standard winter pruning and its combinations are still the most appropriate pruning methods since subdued growth results in high yield with suitable quality. sadjarstvo jablana čas rezi jakost rezi kombinacija rezi fruit growing apple time of pruning intensity of pruning combinations of pruning true true false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2016-09-26 08:48:48 2016-10-06 12:16:45 2022-07-05 03:06:49 2019-07-11 13:56:41 2016 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:UW70GTX0 MAG_Planinc_Rafko_2016.pdf MAG_Planinc_Rafko_2016.pdf 1 46CBDD63D079BD4A1643D873FB9600C4 05645823581f64e1ecd7128af58c388c42e637d4b0511bcdba8bf894247eb690 a52d7195-7c0d-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=106313 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
