Effects of temperature on the development and chemical composition of two cloudberries (Rubus chamaemorus L.) cultivars ("Fjellgull", "Nyby") were studied in a phytotron experiment. "Fjellgull" is a female cultivar while "Nyby" is bisexual (hermaphrodite). Pollen from a male cultivar "Apollen" or from "Nyby" was used to pollinate "Fjellgull". Selfpollination in "Nyby" was assisted by striking open flowers gently with a small brush. In addition, part of the flowers of both cultivars were treated with gibberellic acid (GA3, 10 µg dissolved in 10 µl ethanol). Plants were grown in 24-h photoperiod at constant temperatures of 18, 15, 12 and 9°C. Time from pollination to ripening increased in both cultivars with decreasing temperature from about 35 days at 18°C to about 60-65 days at 9°C. Time for fruit development was not significantly affected by GA3. Berries of "Fjellgull" were significantly larger than those of "Nyby". In both cultivars, the largest berries were found at the treatments 12 or 9°C. On the other hand, seed size was smallest at 9°C and the proportion of seed weight of total fresh weight of berry decreased with decreasing temperature. Treatment with GA3 significantly reduced the average seed size in both cultivars. Pollen type had no significant effect on the rate of development or size of berries in "Fjellgull". Ripe berries were frozen at harvest at -100°C, and tannin enriched extracts were analyzed for metabolites using liquid chromatograpy " mass spectrometric (LC-MS) techniques. In addition total phenols and total anthocyanins were analysed as described by Deighton et al. (2000). Statistical analysis and data mining were performed using a principal component analysis approach. Preliminary results indicate differences in the metabolic profiles between berries grown at low temperatures compared to berries grown at high temperatures.

Bioforsk har hatt flere prosjekter innen juletreproduksjon de siste 10 årene. Målet har vært økt effektivitet i produksjonen og bedre kvalitet på sluttproduktet. Prosjektene har spent over mange tema innenfor produksjonsteknikk og plantehelse.

Following disturbances from a pipeline construction in a coastal heathland, the possibilities to target vegetation development and the balance between Calluna vulgaris and grasses with different fertilization strategies was tested. The effects of fertilization were transient and with time site effects dominated vegetation development.

A publication has been made by Bioforsk in order to survey the subject of urban green areas and human health and well-being from different perspectives. One important reason for doing such a survey in Norway is to show the government how important the urban green areas are. Bioforsk have several areas that may contribute to a better use of the resources used in Norewegian urban green areas. The institute is developing effective and sustainable strategies for controlling weeds and deceases on plant materials. There is also focus on the design and use of urban soils and how to manage urban green areas in order to obtain good quality and low resource input.

Et regionalt utviklingsprosjekt (RUP) for organisk avfall ble presentert og det ble vist til resultater. Det er i regi av prosjektet utviklet gjødsel og vekstmedier basert på behandlet organisk avfall fra flere kilder i Rogaland, blant annet fra to komposteringsanlegg.  Bruken av slam og kompost er i hovedsak rettet mot grøntannleggssektoren.
