Impact of Planting Density on the Incidence Rate of Fruiting Branches of Late-Ripening Plum Cultivars Intended For Processing

Abstract

The paper examines the incidence rate of fruiting branches of plum (mixed-type, long and short fruiting branches, thorn shoots and May blossoms), depending on the planting density in the newer plum cultivars, Krina and Mildora. A simultaneous study was conducted comparing the said cultivars intended for processing, with the standard cultivars of the same purpose, Čačanska rodna and Stanley. The study established that the differences in the quantitative share of the corresponding types of fruiting branches occur as a result of the conditions and systems of cultivation, as well as the cultivar traits and the development phase. May flowers are the most frequent type of fruiting branches in all of the examined cultivars, with a higher percentage share in the dense planting treatments; at the same time, the other types of fruiting branches recorded a higher incidence in the classical cultivation treatments, compared to the dense planting treatments.

U cilju razvoja tehnologije gajenja novijih sorti šljiva pogodnih za sušenje (Krina i Mildora u komparaciji sa standardnim sortama (Čačanska rodna i Stanley) iste namene, ispitvana je i zastupljenost rodnih grančica (mešovite, duge i kratke rodne grančice, trnasti izraštaji i majski buketići) u zavisnosti od gustine sadnje. Razlike u kvantitativnoj zastupljenosti tipova rodnih grančica u ispitivanih sorti šljive je pre svega posledica slova i sistema gajenja, sortnih karakteristika i stadijnog razvitka. Majski buketići su najzastupljeniji tip rodnih grančica kod svih ispitivanih sorti, pri čemu je procentualna zastupljenost veća u teretmanima guste sadnje, sa tendencijom smanjenja u tretmanima sa većim rastojanjima sadnje. Ostali tipovi rodnih grančica su procentualno više zastupljeni u tretmanima klasičnog uzgoja u odnosu na tretmane guste sadnje.
