The behaviour of different rootstock biotypes from the geneva group during the growth and fruit-bearing period in the apple plantation

Abstract

To study the behavior of trees of the Gala Nikangie variety grafted on M9, G11, G41 rootstocks and the Fuji King Grofn variety on the G11 biotype, on a replanted plot in the northern part of the country, an experiment was set up to analyze the development of variety/rootstock associations under the influence of the phenomenon of “soil fatigue”. Planting distance 3.5 x 0.8 m. The height of the trees during 2023 depending on the variety/rootstock association studied recorded values from 233 cm (Gala Nikangie/G11) to 348 cm (Fuji King Grofn/G11). The Gala Nikangie/M9 and Gala Nikangie/G41 associations had average tree height, constituting 251 and, respectively, 272 cm.
