Sweet cherries are grown in areas with suitable local climatic conditions up to 60°N in Norway. All orchards have high density planting systems and are rain covered. The most common system now is multibay high tunnels systems where the trees are under plastic cover from the bloom to the end of the harvest. All orchards are fertigated and the production is aimed to supply the fresh fruit domestic market with high quality fruit from early July and to the end of August. At NIBIO Ullensvang, western Norway a large number of sweet cherry cultivars and advanced selections from worldwide breeding programmes have been evaluated continuously since 1959 and several cultivars have been recommended from this programme for commercial production during the last decades. During the last six years approximately fifty cultivars and advanced selections grafted on the rootstock Gisela 6 have been tested. Important objectives were to obtain large and precocious yields, with important quality parameters like fruit size, fruit firmness, soluble solids, fresh appearance, good flavour and resistance against irrigation induced cracking. Based on the results from the recent testing program, the following cultivars are currently recommended for the fresh fruit market: a) for early season: ‘Adelka’, ‘Pacific Red’, ‘Sweet Aryana’ and ‘Bellise’, b) for mid-season: ‘Brooks’, ‘Giant Red’, ‘Grace Star’ and ‘Folfer’ c) for late season: ‘Van’, ,’SPC 342’, ‘LaLa Star’, Royal Edie’, ‘Tamara’ ‘Lapins’, ‘Royal Helen’, ‘Regina’ and ‘Sweetheart’.

Scots pine (Pinus sylvestris L.) sapwood was modified using maleic anhydride (MA) and sodium hypophosphite (SHP) to improve its durability against wood-deteriorating fungi, mechanical strength, and fire retardancy (thermal stability). The modification significantly reduced mass loss caused by wood-decaying fungi (Trametes versicolor, Rhodonia placenta, and soft rot fungi) due to the formation of cross-links between wood, MA, and SHP, which limited the moisture uptake and altered the chemical structure of wood. On the other hand, the modification did not provide improved resistance to fungi growth on the wood surface, which indicated that the modification had little impact on the accessibility of nutrients on the surface. A bending test showed that the modulus of elasticity (MOE) was not affected by the treatment, whilst the modulus of rupture (MOR) decreased to half the value of untreated wood. Thermal resistance was improved, as demonstrated by micro-scale combustion calorimeter testing, where the total heat release was halved, and the residue percentage nearly doubled. These results indicate that phosphonate protects the modified wood via the formation of a protective char layer on the surface and the formation of radical moieties. Based on the results, wood modified with MA and SHP shows potential for possible use in outdoor, non-loadbearing structures.
