Pomological properties of 11 newly sweet cherry cultivars grafted on Colt rootstock were studied in the region of Macva over a three-year period (2010- 2012). An investigation has included phenological traits (flowering and maturing), the elements of productivity (number of flowers in an inflorescence, fruit set and yield), the most important fruit characteristics (physical, chemical and sensory), and fruit cracking index. Average time of flowering of tested cultivars was in the first and the second decade of April, while the maturing time was between 15 May (‘Early Lory’) and 20 June (‘Penny’). The highest yield was achieved by cultivars ‘Giorgia’, ‘Sunburst’, and ‘Crystalina’. Large fruit size was found in cultivars ‘Penny’, ‘Santina’, ‘Sunburst’, ‘Olympus’, and ‘Kordia’. The lowest susceptibility to fruit cracking was manifested in cultivars ‘Early Lory’ and ‘Giorgia’. Cultivars ‘Kordia’ and ‘Cristalina’ were given the highest sensory ratings. Overall, the best results were shown by medium-early season cultivar ‘Santina’, which can be recommended for commercial cultivation. In addition, the early-season cultivar ‘Early Lory’, and the late-season cultivar ‘Kordia’ can also be recommended for cultivation. [Projekat Ministarstva nauke Republike Srbije, br. TR 31063
Characteristics of productivity and growth (yield per tree, trunk crosssectional area, yield efficiency and fruit weight) were studied in 30 apricot cultivars of medium late and late maturity in the Belgrade area during the six-year period (2009?2014). The cultivar ?Hungarian Best? was used as a control for comparison. The period of study was divided into initial bearing (trees aged three to four years) and full bearing (trees aged five to eight years). Significant differences in yield between cultivars and years were found. An average yield in the period of initial bearing ranged from 0.6 to 6.4 kg per tree, and in the period of full bearing from 4.5 to 18.4 kg per tree. Compared to the control cultivar, significantly higher yield was obtained in 11 cultivars. Adverse weather conditions resulted in a significant reduction in yield in two out of six years of study. Cumulative yield efficiency varied from 0.10 to 0.85 kg/cm2 and in 13 cultivars it was significantly higher compared to the control cultivar. Fruit weight ranged from 26.6 to 81.1 g. Compared to the control, fruit weight was significantly higher in nine cultivars, and significantly lower in ten cultivars. On the basis of high yield and large fruit size, introduced cultivars ?Roxana?, ?Mary de Cenad? and ?Silvercot? as well as domestic cultivars ?Novosadska Rodna?, ?NS-4? and ?NS-6? can be recommended for growing in the Belgrade area.

Growth and productivity characteristics including: initial and final fruit set, yield per tree, trunk cross-sectional area, yield efficiency and fruit weight were studied in ten cultivars of Japanese plums in the Belgrade area for the period of three years (2013-2015). Initial fruit set ranged from 5.6 to 44.4%, and the final fruit set from 2.6 to 23.36%. The high yield per tree (over 10 kg) was obtained in cultivars ?Obilnaja? and ?Morettini 355?, whereas the low yield (under 5 kg) was obtained in cultivars ?Strival?, ?Black Amber?, ?Early Angeleno? and ?Autumn Giant?. The lowest vigor was observed in the cultivar ?Golden Plum?, and the highest in the cultivar ?Strival?. The majority of cultivars had a very large fruit (over 50 g). The yield was strongly positively correlated with initial and final fruit set (r = 0.84**; r = 0.92**, respectively). Fruit weight was moderately negatively correlated with initial and final fruit set (r = -0.67*; r = -0.63*, respectively).

Sažetak: U periodu od pet godina (2013)(2014)(2015)(2016)(2017) na podru ju Beograda ispitivane su fenološke osobine, rodnost i kvalitet ploda 14 sorti šljive srednje poznog vremena zrenja. Kao standard za pore enje je uzeta sorta a anska rodna. Prose no vreme cvetanja je bilo u prvoj polovini aprila, a zrenja plodova u prvoj polovini avgusta. Najmanji prinos po stablu imala je sorta Nevena (1,6 kg), a najviši sorta Mildora (22,5 kg). Statisti ki zna ajno niži prinos u odnosu na standard imalo je sedam sorti. Najmanja bujnost je utvr ena kod standard sorte ( a anska rodna), a najve a kod sorte Milka. Prose na masa ploda je iznosila od 19,5 g (Nevena) do 50,5 g (Valor). U pore enju sa kontrolom, masa ploda je bila statisti ki zna ajno ve a kod pet sorti. Sve sorte su imale visok sadržaj rastvorljive suve materije (iznad 17%), dok je kod sorti Mildora i Valor on bio zna ajno viši u odnosu na kontrolu. Na osnovu rezultata istraživanja, za gajenje se mogu preporu iti slede e sorte: Valor i a anska najbolja kao pretežno stone sorte, Jojo i Vengerka krupna slatka kao sorte kombinovanih svojstava, i Mildora kao sorta za preradu.Klju ne re i: Prunus domestica, cvetanje, zrenje, prinos, osobine ploda. UvodŠljiva je po broju stabala i proizvodnji najzna ajnija vrsta vo aka u Srbiji. Sa godišnjom proizvodnjom od 415.093 t (prosek 2012-2016. godine), Srbija zauzima tre e mesto u svetu, iza Kine i Rumunije. Me utim, u proizvodnji šljive se sre u mnogi problemi kao što su: veliki udeo starih i zapuštenih zasada sa ekstenzivnom proizvodnjom i slabom primenom agrotehni kih i pomotehni kih mera, široka rasprostranjenost šarke šljive, veliki udeo rakijskih sorti lošijeg kvaliteta i manje upotrebne vrednosti plodova, kao i nizak nivo tehnologije prerade. Zbog navedenih razloga, prose an prinos šljive je mali i iznosi 5,3 t/ha (Republi ki zavod za statistiku RS, 2017).
Rezime: U periodu od pet godina (2009)(2010)(2011)(2012)(2013) na području Beograda proučavane su karakteristike 14 novih sorti kajsije stvorenih na Fakultetu za hortikulturu u Lednicama, Republika Češka. Kao standard je uzet klon sorte Velkopavlovická, LE 12/2. Cvetanje ispitivanih sorti je počelo od tri dana pre do jedan dan posle kontrolne sorte, dok je vreme zrenja variralo u rasponu od 19 dana ranije kod sorte Leskora do 12 dana kasnije kod sorte Sophia. Statistički značajno veći prinos u odnosu na kontrolu imala je samo sorta Palava, dok su veću masu ploda imale tri sorte: Candela, Sophia i Betinka. Najbolje ocene za izgled ploda dobile su sorte Sophia i Betinka, a za ukus Marlen i Lebona. Među proučavanim sortama kao perspektivne za gajenje na području Beograda se mogu preporučiti rana sorta Palava, srednje pozna sorta Betinka i pozna sorta Sophia. Ključne reči: Prunus armeniaca, cvetanje, zrenje, prinos, kvalitet ploda. UvodKajsija (Prunus armeniaca L.) ima ograničenu ekološku adaptivnost, zbog čega su vodeće sorte različite u svakom regionu proizvodnje. U svetu se intenzivno radi na stvaranju novih sorti sa poboljšanim osobinama, kao što su: dobra adaptivnost na različite ekološke uslove, duži raspon sazrevanja, samooplodnost, veća otpornost na prouzrokovače bolesti, veća rodnost i bolji kvalitet ploda. Introdukcija novih sorti i njihovo proučavanje u našim agroekološkim uslovima omogućava proširenje izbora sorti za gajenje kao jednog od načina unapređenja proizvodnje kajsije. U poslednjih 20 godina u svetu je stvoreno više od 500 novih sorti kajsije. Najveći broj novih sorti je stvoren u SAD, a zatim slede Francuska, Italija, Rusija, Španija, Rumunija, Ukrajina i Češka (Milatović, 2013a).Na Fakultetu za hortikulturu, Lednice (Mendelov univerzitet za poljoprivredu i šumarstvo, Brno) rad na oplemenjivanju kajsije je počeo 1960. godine sakupljanjem i proučavanjem
