Growth and fruit-bearingof raspberry varieties according to production cycle

Abstract

One of the main goals of the research is to have clarity regarding the systems of growing remontant raspberries on a single production cycle compared to 2 production cycles. Biometric analyses demonstrated greater height growth in variants with annual or only biennial stems. The object of the research were plants of the remontant varieties Enrosadira, Polonez and Polana cultivated in open ground. The planting distance was 2.5 m x 0.5 m. The following variants were studied: V1 -10 annual stems per linear meter; V2 -10 biennial stems per linear meter; V3 -8 annual stems and 8 biennial stems per linear meter (Control). Higher productivity was obtained in the Polonez variety, with fruiting on annual and biennial stems in the same growing season, followed by the ,,Enrosadira’’ variety, with fruiting on annual stems.
