20.500.12556/RUL-161193 Vpliv poletne rezi na pridelavo breskev (Prunus persica) The effect of summer pruning on peach production (Prunus persica) Poletna rez je hortikulturna praksa, ki omogoča boljše upravljanje z drevesi. Pomembna je v kombinaciji z zimsko rezjo in je odvisna od starosti drevesa, sorte breskev, podlage in podnebja. Poznamo različne jakosti poletne rezi, ki imajo vpliv tako na količino kot kakovost plodov. Pri poletni rezi poskrbimo z izrezovanjem starega lesa, preveč bujnih poganjkov in redčenjem rodnih brstov za povečanje intenzivnosti svetlobe v krošnji in s tem za večjo kakovost in intenzivnost barve plodov. Poletno rez lahko izvajamo zgodaj poleti ali pozno poleti tik pred obiranjem. Zgodnja poletna rez lahko vpliva na kakovost in količino pridelka še isto leto, pozna poletna rez pa omogoča lažje obiranje in vpliva na kakovost in količino pridelka običajno naslednje leto, isto leto pa vpliva na intenzivnost barve plodov. Napačna poletna rez lahko povzroči poškodbe tako na drevesih kot na plodovih, premočna rez pa lahko povzroči sončne ožige pri breskvah. Kakovostna poletna rez poveča tako količino kot kakovost pridelka in omogoča rast glavnih poganjkov, hkrati pa zmanjša potrebo po vodi in potrebnem namakanju v sušnih poletnih mesecih. Summer pruning is a horticultural practice that enables better management of trees. It is important in combination with winter pruning and depends on the age of the tree, the peach cultivar, the rootstock, and the climate. There are different intensities of summer pruning, which affect both the quantity and quality of the fruit. During summer pruning, old wood, overly vigorous shoots, and thinning of fruit buds are removed to increase light penetration in the canopy, thus enhancing the quality and color intensity of the fruit. Summer pruning can be done early in the summer or late in the summer just before harvest. Early summer pruning can affect the quality and quantity of the harvest in the same year, while late summer pruning makes harvesting easier and usually affects the quality and quantity of the harvest the following year, although it impacts the color intensity of the peaches in the same year. Improper summer pruning can cause damage to both trees and fruit, and excessive pruning can cause sunburn on the peaches. Quality summer pruning increases both the quantity and quality of the yield and promotes the growth of main shoots, while reducing the need for water and irrigation during dry summer months. sadjarstvo breskev Prunus persica poletna rez rodnost rast pridelek fruit growing peach Prunus persica summer pruning fertility growth yield true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2024-09-08 07:17:22 2024-09-08 07:17:25 2024-09-11 10:06:10 0000-00-00 00:00:00 2024 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 243851 207090947 41456.pdf 41456.pdf 1 B4923450AE08C070CB4AB21BF706DFE5 143de28cb3a24f1c4eabcd722d135c68fa2834f072cd6bf17928306b36be6eb6 9a087059-6da1-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=190078 Biotehniška fakulteta 0 0 0
