In a project focusing on semi-cultivation of European blueberry (EB) from 2008 to 2011, a botanical survey was undertaken in two experimental fields in the municipalities of Snåsa and Lierne in the county of Nord-Trøndelag, Norway. The focus was mainly on growth of EB and Vaccinium vitis-idaea. We examined the effects of fertilization and cutting of EB to evaluate if established practices in the semicultivation of the wild American lowbush blueberry (Vaccinium angustifolium), also had potential for semi-cultivation of EB. We assigned four levels of fertilization randomly per block, with five replications. The Snåsa and the Lierne fields were clearcut, 25 and 5 years prior to the survey, respectively. We pruned the remaining trees and shrubs to the ground when the experiment was established. Before application of fertilizer and cutting, we conducted a vegetation survey, recording the percentage cover of all plant species. Furthermore, we recorded maximum, minimum, and middle canopy height of EB and estimated percent cover and thickness of plant litter at the forest floor in 2008 and 2011. The survey consisted of three plots of one m2. We placed each of them in the center of a fertilization plot, randomly distributed across the four fertilization treatments of each block at both sites. Twenty-six species were present in the fields, and the changes in botanical diversity were influenced by year, location, fertilization, and pruning of shrubs. Suggestions of how development of European blueberry in forest fields could be strengthened, and subsequently how the competitors could be weakened are presented. We showed that Pruning of EB decreased canopy cover, maximum- and middle- height, which was still lower three years after pruning than unpruned plants, and that V. vitis-idaea had a lower nutrient demand than EB.

NIBIO fikk i 2016 i oppdrag fra Fylkesmannen i Buskerud og foreta en registrering av den seminaturlige engfloraen på Haugplassen på Raje i Kongsberg kommune. Denne rapporten gir en oversikt over planter og vegetasjonstyper som ble registrert under befaringen 29.juni 2016. Slåttemarka på Haugplassen er artsrik og inneholder flere sjeldne arter. Tidligere funn av andre artsgrupper, bl.a. innsekter, på Haugplassen er hentet ut fra Artskart (www.artsdatabanken.no) og vedlagt rapporten.

The aim of the study was to investigate changes of physical, microbiological, and sensory properties of muesli with germinated fakes during storage. Germinated fakes were made from conventionally grown grains: hullless barley, hull-less oat, rye, wheat, and triticale in various proportions. Breakfast cereals samples were packaged in Doypack (stand up pouches) made from Pap50g/Alu7/ Pe60 (Pap/Alu/PE) and stand up pouches Fibrecote® HB MG 40/60 (PE/EvOH/Pap) and stored for 6 months at temperature t=35±2°C and relative air humidity φ=55±3%, to provide accelerated shelf-life testing. The main quality parameters such as total plate count, yeasts and mould, water activity, moisture content, water absorption and sensory properties—taste, aroma, consistency, and appearance were analysed using the standard methods. The results of the present experiments demonstrate that the best quality of dried breakfast cereals after storage in terms of sensory quality, microbiological stability, moisture migration, and water absorption were achieved in the Fibrecote® HB MG 40/60 pouches. This study revealed that breakfast cereals made from rye, triticale germinated triticale, germinated hull-less oat, germinated hull-less barley fakes; as well breakfast cereals made from triticale, oat, germinated wheat, germinated triticale, and germinated hull-less barley fakes packaged in Fibrecote® HB MG 40/60 can be stored for 12 months at temperature 23±2°C; but breakfast cereals made from wheat, rye, triticale, germinated hull-less oat, germinated hull-less barley, germinated rye fakes and package in same packaging material can be stored for 10 months at temperature 23±2°C.
