Ежегодно реализация семян злаковых трав для газонных насаждений в пяти странах Скандинавии составляет 6 тыс. тонн. В настоящее время на рынке Северной Европы доступно в продаже около 200 различных сортов 15-ти видов и подвидов злаковых трав, используемых для озеленения. Настоящий каталог основан на научном исследовании «Оценка сортов полевицы (Agrostis) и овсяницы (Festuca) для использования на полях для гольфа в условиях грина в Скандинавии (2003-2007)», а также на результатах почти 20-летнего скандинавского официального сортоиспытания злаковых трав для газонов различного типа. В каталоге приводится подробное описание сортов, которые находились в сортоиспытании, а также даются независимые и конкретные рекомендации по выбору тех или иных видов и сортов для использования на гринах, фейрвеях/ти, домашних газонах, футбольных полях и газонах специального назначения. Рекомендиции даются для 2 климатических зон, а именно для южной/прибрежной климатической зоны (зона 1), которая охватывает Данию, южную Швецию и прибрежные регионы южной и западной Норвегии, а также для северной/континентальной климатической зоны (зона 2), которая включает в себя Финляндию, среднюю и северную часть Швеции, среднюю и северную часть Норвегии, внутреннюю часть южной Норвегии и Исландию. «Скандинавский каталог сортов газонных трав, 2007» финансируется Скандинавским фондом исcледований в области дерновых трав и окружающей среды (STERF) и планируется пересматриваться и дополняться каждые 3-4 года на основании проводимых сортоиспытаний.

Viktige eigenskapar til ei grunnstamme er å regulera veksten og gje store og jamne avlingar av kvalitetsfrukt. Gjennom eit stort foredlingsarbeid i fleire land i Europa dei to siste 10 åra, har det lukkast å foredla fram ei rad grunnstammer med moderat vekst, tidleg bering og god bereevne. Denne rapporten omtalar resultat av utprøving av 27 ulike grunnstammer med redusert vekst til søtkirsebærsorten Lapins gjennomført ved Bioforsk Ullensvang i åra frå 1999-2006. Dette er del av eit europisk samarbeidsprosjekt der 11 land er med.

Gibberellin er eit plantehormon som førekjem naturleg i høgare planter. Det fremjar særleg vekst, men har også innverknad på t.d. kvile, fruktsetjing og modning. I mange land vert søtkirsebærtrea sprøytte med den syntetisk framstilte gibberellinsyra GA3 3-4 veker føre hausting når fruktene er stråfarga (gule). Dette fører til at fruktene vert fastare, fargeutviklinga utsett og dermed modninga med opp til ei veke Gibberellin manglar praktisk utprøving i Noreg og er ikkje godkjent til kommersiell bruk. For å skaffa turvande dokumentasjon for offentleg godkjenning til yrkesdyrking i Noreg, vart det gjennomført biologisk utprøving ved Bioforsk Ullensvang i 2005 og 2006 og hjå dyrkarar i Lærdal og Telemark i 2005. Resultata viste at bioregulatoren GA3 utsette modninga med nær ei veke og gav fastare og større frukter hjå sortane Van og Lapins. Dette fører til ei meir robust frukt i marknaden. Lagringseigenskapane vart ikkje endra. Høveleg dosering er 20 ppm GA3 som ei sprøyting ved strå-gul farga kart.

Laminaria has been known in Asia, first as kunbu ("large cloth") and, more recently, as haidai ("sea ribbon"). Internationally, "kelp" is generally used. The main extracted products are alginate, iodine and mannitol, which are used in textile, printing, medical and food manufacturing industries. Laminaria in its whole is also used in a huge variety of products for human consumption. In Europe, the exploited species have been L. digitata, hyperborea and saccharina. Mostly harvested as source of saltworth and iodine, wild thallus have also been used as fertizers in agriculture. In 2005, Laminaria is still harvested as alginates sources in Norway (L. hyperborea : 153 906 t) and France (L. digitata : 74 778 t). No cultivation is actually in place. In the late 1920s, the commercial seaweed Laminaria japonica was introduced into China from Hokkaido (Japan). Although commercial production of kelp harvested from its natural habitat has been carried out in Japan for over a century, mariculture of this cold water species on a very large commercial scale has been realized in China in the 1950s. Since, the Chinese kelp production increased from about 60 000 t annually to over 4 millions tones in 2005, making China the world largest producer of Laminaria. The Chinese success of the kelp cultivation in Asia has mainly depended on the adoption of three important techniques: the floating raft method, low temperature cultivation of summer seedlings, and  application of nitrogen fertilizer in the open sea. The Chinese methods that have made Laminaria production successful are shortly described in this poster.

This Pest Risk Assessment (PRA) of the fire blight bacterium Erwinia amylovora was initiated by a review or revision of a policy by the Norwegian Food Safety Authority. Fire blight was detected in Norway for the first time in 1986. The focus of infection was in and around the city of Stavanger in Rogaland county on the south west coast of the country. Mainly Cotoneaster bullatus and C. salicifolius were attacked.  The disease was contained and finally eradicated from the area in 1992. However, in 2000 fire blight re-emerged, in the same county, on the island Karmøy, separated from the first outbreak by 25 km open sea. A new containment and eradication programme was started. Nevertheless the disease continued to spread to the north, mainly due to the movement of beehives contaminated with E. amylovora, from areas with diseased plants to areas free from fire blight with warm and humid weather conditions, favorable for the development of the disease. Fire blight has been detected in private gardens, around public buildings, in recreation grounds, along roads, and in rural areas in the coastal areas of the counties of Rogaland, Hordaland and Sogn og Fjordane. It has not been detected in nurseries, in fruit-growing areas, or in other parts of the country. The main hosts are still C. bullatus and C. salicifolius and some other Cotoneaster spp. Occasionally diseased Sorbus aria, Pyrachanta and apple and pear have been detected. Recently a very limited outbreak on C. bullatus and C. salicifolius was detected in the city of Kristiansand in Vest-Agder county. The endangered area, where presence of fire blight will result in economically important loss is the commercial fruit growing areas of Norway. If E. amylovora is introduced into the main fruit growing districts, it is expected that the damage and losses to commercial fruit production and nurseries will be minor, under the current phytosanitary regime in Norway. Relaxation of the regulations in force for fighting fire blight in Norway will increase the expected damage and losses to commercial fruit production and nurseries to a moderate level. Importation of fruit trees and fruit tree propagation material from countries where fire blight is established is not expected to increase the risk of fire blight in Norway significantly, given that appropriate phytosanitary requirements and quarantine are followed.
