20.500.12556/DKUM-77316 Vpliv intenzivnosti rezi na pridelek češenj (Prunus avium L.) sort 'Regina' in 'Kordia' Effects of Different Pruning Intensities on Sweet Cherry (Prunus avium L.) Cultivar 'Regina' and 'Kordia' yields Na Univerzitetnem kmetijskem centru Pohorski dvor na Fakulteti za kmetijstvo in biosistemske vede Univerze v Mariboru smo v letu 2019 v nasadu češenj sort 'Regina' in 'Kordia', cepljenih na podlago Gisela 5, izvedli poskus, v katerem smo testirali vpliv intenzivnosti zimske rezi na količino in parametre kakovosti pridelka. Poskus je obsegal štiri obravnavanja, ki so predstavljala šibko, standardno in močno rez ter kontrolo. Pri šibki rezi smo izvedli osvetlitveno rez, pri standardni smo osvetlitveno rez dopolnili s pomlajevanjem rodnih nosilcev v višjih delih krošnje ter izrezovanjem šibkega rodnega lesa, pri močni rezi pa smo ob standardni rezi izvedli še prikrajševanje enoletnih poganjkov na dve vegetativni očesi. Pri kontrolnem obravnavanju rez ni bila izvedena. Ugotovili smo, da se skupni pridelek z intenziviranjem rezi manjša, povečata pa se debelina in masa plodov. Vpliv intenzivnosti rezi na notranje lastnosti pridelka ni konsistenten. Reakcija dreves sorte 'Regina' na intenzivnost rezi je bolj konsistentna in predvidljiva, kot pri sorti 'Kordia'. In 2019, at the University Agricultural Centre Pohorski Dvor of the Faculty of Agriculture and Life Sciences, University of Maribor, an experiment was conducted in a sweet cherry plantation of ‘Regina’ and ‘Kordia’ grafted on Gisela 5 rootstock in order to study the effects of different intensity of dormant pruning on yield quantity and quality. The experiment included four different treatments, which represented light, standard and severe pruning and control (no pruning). In light pruning, crown was thinned, whereas in standard pruning approach, in addition to crown thinning, pruning also involved rejuvenation of fruit bearing wood in the upper part of the crown and thinning of poorly fruiting branches. The severe pruning included additional shortening of one-year shoots to two vegetative buds. In control, no pruning took place. The results show that intensification of dormant pruning has negative impact on yield quantity and positive impact on fruit diameter and fruit weight. The influence of the different intensities of pruning on internal fruit quality was not consistent. The reaction of the sweet cherry variety ‘Regina’ was significantly more predictable and consistent when compared to the variety ‘Kordia’. češnja Prunus avium rez 'Regina' 'Kordia' kvaliteta plodov pridelek sweet cherry Prunus avium pruning 'Regina' 'Kordia' fruit quality yield quantity true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2020-08-26 15:41:57 2020-09-08 10:06:08 2022-08-09 14:38:57 2020-09-11 03:21:57 2020 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:QQ6HDFCR UN_Tojnko_Nina_2020.pdf UN_Tojnko_Nina_2020.pdf 1 E2165BE644A5F877045EA4852D8E47A4 4bc8d725200e5d74eb6148ed907fe77f5477a1df61aebaa1da0f15e3829203fd bdfb0cf6-7c11-11eb-bb7a-00155d0001ca 20.500.12556/dkum/2a17f709-46bb-4634-83dd-147cfbbe6e5d https://dk.um.si/Dokument.php?lang=slv&id=144694 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
