The impact of the crown shape on the growth and fructification of cherry tree varieties grown in an intensive system

Abstract

The aim of the research was to increase the productivity of sweet cherry orchards by identifying highly productive crown shapes for the Early Star, Samba and Black Star varieties, grafted on Gisela 6, suitable for the Republic of Moldova. The researches were carried out in the central orcharding area of the Republic of Moldova, at the StarAgroGroop Ltd., between the years 2018-2021. The impact of the crown shape on the growth and fructification of the Early Star, Samba and Black Star cherry tree varieties, grafted on the rootstock Gisela 6, was studied. The trees were established in 2015. The orchard had a planting density of 1250 trees/ha. The crowns of the trees were of improved thin spindle shape, and of Cup and Kym Green Bush shape.
