Elementi rodnosti stonih i industrijskih sorti prave breskve

Morphologic characteristics of fruiting branches and percentage of fruit set in 20 cultivars of stone and industrial peach cultivars were investigated in order to show its fruiting potential based on all elements of productivity. In both group of peaches shoots that are 60-70cm long, were dominating. Number of flower buds per shoot and per meter was higher in industrial peach cultivars. Fruit set was high (65-88%) and similar in both group of peach cultivars. Average of the final fruit set in stone peach cultivars was 43.4%, while in industrial peach cultivars was higher and was 50.3%. Yield, expressed in kg per meter was for about 30% higher in industrial peach cultivars. In the scope of the examined groups, peach cultivars differ between each other in all investigated elements, but yielding and very yielding cultivars are dominating.U radu su ispitivane morfološke osobine rodnih grančica, kao i stepen oplodnje kod 20 sorti prave breskve podeljenih u dve grupe: stone i industrijske sorte, kako bi se na osnovu ovih elemenata rodnosti, ukazalo na njihove potencijalne prinose. Kod obe grupe sorti dominiraju mešovite rodne grančice dužine od 60-70 cm. Broj cvetnih pupoljaka po mešovitoj grančici i dužnom metru je veći kod industrijskih sorti breskve. Broj zametnutih plodova je visok (65-88%) i kod obe grupe sorti približno isti. Broj održanih plodova do berbe kod sorti obične breskve je iznosio prosečno 43,4%, dok je kod industrijskih sorti bio veći i iznosio je prosečno 50,3%. Prinos, izražen u kg po dužnom metru je za oko 30% veći kod industrijskih sorti. U okviru ispitivanih grupa, sorte se međusobno razlikuju po svim ispitivanim elementima, a dominiraju rodne i vrlo rodne sorte
