Effect on plant development and fruit quality of European blueberry (Vaccinium myrtillus) at different climatic growing conditions in Norway

Examination of European blueberry (EB) populations from different latitudes in Norway starting in 2008, have revealed results that indicate differences in growth, fruit yield and fruit quality. The examinations have been executed in subpopulations at latitudes 61, 64 and 69°N (respectively south, mid and north of Norway). Effects of fertilization, cutting of plants, climate etc have been examined in forest fields and on cultivated land. Plants have also been propagated and growth patterns have been examined under controlled conditions. Fruit samples from all locations have been analyzed for important biological components. This presentation will give an overview of some of the results obtained during the two first years of the project period.
