dc.description.abstract | U radu je ispitivan je uticaj zimskog i poznog prolećnog mraza na izmrzavanje generativnih organa kod 33 sorte kajsije na području beogradskog Podunavlja u toku 2012. godine. Apsolutna minimalna temperatura od -20,7°C zabeležena je 9. februara, dok je 10. aprila došlo do pojave poznog prolećnog mraza intenziteta -3,0°C. Prosečno izmrzavanje cvetnih pupoljaka od zimskog mraza iznosilo je 32,8%, sa variranjem od 12,1% kod sorte NS-6 do 98,8% kod sorte Mary Lady. Pozni prolećni mraz, koji se javio nakon završetka cvetanja, doveo je do prosečnog izmrzavanja od 61,4% plodića, sa variranjem od 18,1% kod sorte Bergarouge do 93,0% kod sorte Silvercot. Iako su zimski i pozni prolećni mraz uticali na značajno smanjenje roda, 11 sorti je i pored toga dalo zadovoljavajući prinos (više od 10 kg po stablu). Najviši prinos su dale sorte Harcot, Litoral i Re Umberto. | sr |
dc.description.abstract | The influence of winter and spring frost on the injury of flower buds and flowers was studied in 33 apricot cultivars during 2012 year. The experimental orchard was planted in 2007 at the Experimental farm “Radmilovac” of the Faculty of Agriculture in Belgrade. The rootstock is Myrabolan (Prunus cerasifera Ehrh.) seedling, and the tree spacing is 4 x 1.5 m. Winter frost intensity of -20.7°C, which occurred on 9th February, caused the average injury of 32.8% of flower buds for all studied apricot cultivars. Frost damage was highest in cultivar ‘Mary Lady’ (98.8%), and lowest in cultivar ‘NS-6’ (12%). Spring frost intensity of -3.0°C occurred on 10th April, after apricot cultivars finished flowering. It caused the average injury of 61.4% of fruitlets. The damage was lowest in cultivar ‘Bergarouge’ (18.1%), and the highest in cultivar ‘Silvercot’ (93.0%). Due to the occurrence of winter and late spring frosts, there was a signifiucant reduction in yield of apricot. The average yield for all cultivars was 7.2 kg per tree. Four cultivars practically had no yield (‘Mary Lady’, ‘Palstein’, ‘Aurora’, and ‘Silvercot’). The highest yield was found in cultivars ‘Harcot’, ‘Litoral’, and ‘Re Umberto’. | sr |
