Growth and fructification of cherry trees

Abstract

The experiment was carried out during the years 2012-2013 on varieties cultivar 'Valerii Cicalov' and cultivar 'Record' cherry trees (Cerasus avium L.M.) grafted on the mahaleb rootstock (Cerasus mahaleb Mill), planted at a spacing of 6x5 m on a sandy loam soil with low status of organic matter. The trees have been formed after natural ramification improved with high volume. The staggered cutting of older branches during vegetation period (V4) and rest (V3) in wood for 3-4 years, advantages the formation of older branches and fruit branches, compared to cutting production during the rest period (V1) and vegetation period (V2). The fruit harvesting in 20122013 was 20.1-33.4 kilos/tree of cultivar 'Valerii Cicalov' and 18.9-26.4 kilos/tree of record. The staggered cutting of older branches branches during the vegetation period garnishes the frame with fruit branches, provides an increase of fruit production by 32% to cultivar 'Valerii Cicalov' and by 21% to cultivar 'Record' compared to cutting production during the rest period (witness).
