Cherry cultivation has a long tradition in Bosnia and Herzegovina mainly due to favorable climatic conditions for cherry growing in this region. However, current cherry production is insufficient ...because of prevailing old cultivars and rootstocks. Modern intensive production of sweet cherry (Prunus avium L.) requires planting of high quality cultivars on dwarfing rootstocks planted in high density orchards. Cherry rootstock breeding programs worldwide require data on tolerance and performance of their rootstocks in different climatic conditions. Therefore, the influence of two cherry rootstocks ('Gisela 5 and 'Santa Lucia 64') on phenological events (blooming), growth and pomological properties of two cherry cultivars ('Stella' and 'Burlat') planted in modern orchard (managed according to standard commercial practice for integrated fruit production), near Sarajevo was evaluated. The trees grafted on 'Gisela 5' rootstocks were planted in 2004 and on 'Santa Lucia 64' in 2005. All tress were trained in a spindle system and the analyzed parameters were monitored in 2010. Rootstocks greatly influenced blooming time, growth and fruit characteristics of both investigated cultivars. The weaker rootstock was 'Gisela 5', which stimulated earlier blooming and caused statistically significant better fruit characteristics (fruit size, % flesh of fruit as well as total soluble solids content in fruit). The results of the analysis showed that both cherry cultivars reached better fruit quality on 'Gisela 5'. 'Stella' had better fruit quality than 'Burlat'. 'Santa Lucia 64' proved a better rootstock for 'Burlat' than for 'Stella'.
Gojenje češenj v Bosni in Hercegovini ima dolgo tradicijo. Glavni razlog so ugodne klimatske razmere za gojenje češenj. Vendar pa je trenutna pridelava češenj premajhna zaradi starih sort in njihovih podlag. Sodobna intenzivna pridelava češenj (Prunus avium L.) zahteva sajenje visokokakovostnih sort na šibkih podlagah v nasadih z gostim sajenjem. Programi vzgoje novih češnjevih podlag po svetu potrebujejo podatke o odpornosti in obnašanju podlag v različnih klimatskih razmerah. Ugotavljali smo vpliv dveh češnjevih podlag ('Gisela 5' in 'Santa Lucia 64') na fenološke lastnosti (cvetenje), rast in pomološke lastnosti dveh češnjevih sort ('Stella' in 'Burlat'), ki sta bili posajeni v sodobnem nasadu blizu Sarajeva, oskrbovanem po načelih integrirane pridelave. Drevesa na podlagi 'Gisela 5' so bila posajena leta 2004 in na podlagi 'Santa Lucia 64' leta 2005. Drevesa smo opazovali v letu 2010, vzgojena so bila v gojitveni obliki vretenast grm. Podlagi sta značilno vplivali na cvetenje, rast in na značilnosti plodov pri obeh obravnavanih sortah. Šibkejša podlaga je bila 'Gisela 5', kjer je bilo cvetenje zgodnejše in plodovi so imeli boljše značilnosti (velikost ploda, delež mesa kakor tudi vsebnost suhe snovi v plodu). Analiza je pokazala, da sta obe češnjevi sorti razvili bolj kakovostne plodove na podlagi 'Gisela 5'. Sorta 'Stella' je imela kakovostnejše plodove kot sorta 'Burlat'. Za sorto 'Burlat' je podlaga 'Santa Lucia 64' bolj primerna kot za sorto 'Stella'.
The influence of late-season boron (B) application on the bud B concentration and fruit set was studied in sweet cherry (Prunus avium L.). The experiment was carried out on 5-year-old Summit and ...Hedelfinger trees on rootstock Gisela 5 in Fruit Growing centre Gacnik. Trees were sprayed with B (1% Bortrack) or water (control). Differences in B concentration were measured between cultivars, the highest content in Hedelfinger buds. Boron application resulted in increased B concentration in flower buds. Fruit set was influenced with cultivar, boron application and micro location. Fruit set was statistically higher in Hedelfinger than in Summit trees. The results showed that B fertilization had no effect on fruit set of Summit despite increased concentration of boron by 94.8% in dormant flower buds. Foliar boron spraying of Hedelfinger was effective in increasing B concentration (by 157.2%) and fruit set on half trees.
