New sweet cherry cultivars in intensive plantings

Abstract

The study took place in the largest sweet cherry plantation in West Hungary. The purpose has been the identification of those varieties, which will be suitable for intense cultivation, early fruiting and excellent fruit quality, moreover, the selection of the optimal phytotechnical procedures. At the same time, scion-rootstock combinations have been tested also from the point of view of growing intensity and fruiting in high-density plantation. The dense planting is induced to start fruiting early and yield regularly by special methods.Yielding was stimulated by maintaining the balance of vegetative-generative growth by binding the shoots, by summer pruning, by cuts on the trunk and root pruning. Best experiences have been found in yield and quality in the following varieties: Canada Giant, Carmen, Firm Red, Giant Red, Katalin, Kordia, Regina. Dense planting has been feasible also on vigorous rootstock, like P. mahaleb. Dwarfing rootstocks like P-HL-A, Gisela 6, accelerate the formation of flower buds and yielding earlier with fruits of adequate size. ‘Firm Red’ and ‘Giant Red’ excelled with their large fruit (>27 mm diameter) in all combinations, thus being promising under Hungarian conditions.

Performance of sweet cherry cultivars grafted on Colt rootstock

“…Based on Vaszily & Gonda (2010) researches planting orchard with high density on Prunus mahaleb rootstock is achievable, nevertheless special pruning policy recommended for each cultivar to maintain high yield and fruit quality for a longer period. Szabó et al (2011a) also confirmed this state proving that intensive growing technology can be performed also on growth inducing rootstocks, but dwarfing rootstocks (PHL-A, Gisela 6) can provide earlier cropping and adequate fruit size at the same time.…”

Cseresznyefák terméshozását és gyümölcsminőségét befolyásoló műtrágya kísérletek eredményei

“…A cseresznye minőségét leginkább a gyümölcs mérete, színe, húskeménysége, aromája határozza meg (ESTI et al, 2002;SIMON et al, 2004;USENIK et al, 2005;MUSKOVICS et al, 2006;SZABÓ et al, 2011;GABRIELE et al, 2013;CSIHON et al, 2018). Emellett táplálkozás-élettani szempontból fontos értékmérő a tápelem-, a fenolos vegyület-, az antocianin-, és az antioxidáns-tartalma is (WANG at el., 1997;KIM et al, 2005;JAKOBEK at el., 2007).…”
