Abstract [en]

Trees of Bergvik apple (Bergviksäpple) planted between 2001 and 2007 have shown varying harvest. This study investigates why some trees gets low or no harvest while others get significantly higher harvest. The aim is to identify some reasons why fruiting differs between the trees and if possible suggest and/or enlighten the tree owners what can be done to improve fruiting. The study includes 25 trees, mostly located in Hälsingland, Sweden. The tree owners have answered two questionnaires, first in the spring with questions regarding flowering and the second in the autumn, regarding harvest. The answers to these questionnaires form the foundation for this work.

The result of the study reveals differences in harvest. Older trees and/or trees with good vegetative growth have larger harvest while trees with poor growth in some cases didn’t even get flowers. Younger trees with good growth gave good harvest. This concludes that the single most important factor to get good harvest is good vegetative growth.
