Shoot growth peculiarities, remontancy and realization of the potential productivity of remontant raspberry varieties in the north

For the first time in the conditions of the Komi Republic, we have studied the collection of remontant raspberry varieties and identified promising varieties among them to form agrophytocenoses being highly resistant to the action of biotic and abiotic stressors. The article highlights the shoot growth peculiarities, remontancy and realization of the potential productivity of remontant raspberry varieties under conditions of the Komi Republic. The authors have identified varieties with a high remontancy degree in terms of: length of the autumn fruiting zone and number of laterals on a shoot. The highest potential productivity of the studied varieties has been evaluated. The study results of 2021 provide for the experimental data for the subsequent development of the guidelines on formation of adaptive remontant raspberry agrophytocenoses in the conditions of the Komi Republic.
