Phenotypic expression of vigor in sour cherry cultivars on different rootstocks

Abstract

Influence of 4 different rootstocks (Colt, wild cherry seedling, mahaleb seedling and wild cherry seedling with Oblačinska sour cherry as interstock) on expression of vigor index characteristics (tree height, trunk circumference, canopy diameter, shoot diameter and internode length) in 4 sour cherry cultivars (Early Meteor, Rexelle, Heimanns Konserven, and Kelleris 14) were examined. The largest values for the majority of investigated properties were established on generative rootstocks, and the smallest on interstock. Total variability of trunk circumference and canopy diameter were influenced, in the largest percentage, by rootstock, while total variability of tree height, shoot diameter and internode length were influenced, in the largest percentage, by genetic base of the cultivar.

Ispitivan je uticaj 4 različite podloge (Kolt, sejanac divlje trešnje sejanac magrive i sejanac divlje trešnje sa Oblačinskom višnjom kao posrednikom) na ekspresiju osobina pokazatelja bujnosti (visina stabla, obim debla, prečnik krune, prečnik letorasta i dužina internodija) kod 4 sorte višnje (Rani meteor, Reksele, Hajmanova konzervna i Keleris 14). Najveće prosečne vrednosti za većinu proučavanih osobina ustanovljene su na generativnim podlogama, a najmanje na posredniku. Ukupna varijabilnosti obima debla i prečnika krune u najvećem procentu je bila uslovljena podlogom, dok je ukupna varijabilnost visine stabla, prečnika letorasta i dužine internodija u najvećem procentu bila uslovljena genetičkom osnovom sorte.
