Abstract
During the 2012. in experimental field of Faculty of agriculture 'Radmilovac' was examined the susceptibility of varieties of quince on late spring frost. Low temperature (-3.02°C) was recorded on 10th April 2012. By analysis of obtained results there were found significant differences between the varieties in terms of susceptibility of flower buds on late spring frosts. The greatest damage from late spring frosts (above 70.0%) was found in varieties: Hemus, Rea's Mammoth, Asenica and Vranjska, and minimum damage in the varieties: Mehelnica and Leskovačka (below 10.0%). The degree of injuries was higher in flower buds of quince that were more developed and in the varieties that earlier begin with the flowering.
Tokom 2012. godine na Oglednom dobru 'Radmilovac' Poljoprivrednog fakulteta u Beogradu ispitivana je osetljivost sorti dunje na pozni prolećni mraz. Niska temperatura (-3,02°C) je zabeležena 10. aprila 2012. godine. Analizom dobijenih rezultata, utvrđene su vrlo značajne razlike između ispitivanih sorti u pogledu osetljivosti cvetnih pupoljaka prema poznim prolećnim mrazevima. Najveće štete od poznih prolećnih mrazeva (preko 70,0%) registrovane su kod sorti: Hemus, Rea's Mammoth, Asenica i Vranjska, a najmanje kod sorti: Mehelnica i Leskovačka (ispod 10,0%). Stepen izmrzavanja je veći kod cvetnih pupoljaka dunje koji su razvijeniji i kod sorata koje ranije počinju sa cvetanjem.
