What does Cicero (Center for International Climate and Evironmental Reasearch " Oslo) think about the climate change? What will the consequences be for the turf and golf sector? What will the consequences be for the choice of species and varieties? What aims will be important for turf grass breeding in the Nordic countries? Breeding of turf grasses today

Klimascenarier for Norge indikerer en temperaturøkning om vinteren, og for noen områder en økning i nedbør om høsten. Med utgangspunkt i en kanadisk undersøkelse beregnet vi de samme klima indekser for norske forhold i et forsøk på å vurdere effekter på overvintringsevnen til forgras. Vi brukte SnowFrostIce modellen til å simulere snødekke, teledyp og isdekke. Klimaindeksene reflekterer risiko for vinterskader relatert til frost intensitet, varighet av snødekket og isinnkapsling. Klimaindeksene ble beregnet for tre lokaliteter som representerer forskjellig klima:Sola (58° 53" N 5° 38" E, 7 moh) SV kyst, Løken (61° 7" N 9° 4" E, 525 moh) SØ innland, og Tromsø (69° 39" N 18° 55" E, 100 moh) N kyst.

Detailed knowledge of temperature effects on the timing of dormancy development and bud burst will help evaluate the impacts of climate change on forest trees. We tested the effects of temperature applied during short-day treatment, duration of short-day treatment, duration of chilling and light regime applied during forcing on the timing of bud burst in 1- and 2-year-old seedlings of nine provenances of Norway spruce (Picea abies (L.) Karst.). High temperature during dormancy induction, little or no chilling and low temperature during forcing all delayed dormancy release but did not prevent bud burst or growth onset provided the seedlings were forced under long-day conditions. Without chilling, bud burst occurred in about 20% of seedlings kept in short days at 12 C, indicating that young Norway spruce seedlings do not exhibit true bud dormancy. Chilling hastened bud burst and removed the long photoperiod requirement, but the effect of high temperature applied during dormancy induction was observed even after prolonged chilling. Extension of the short-day treatment from 4 to 8 or 12 weeks hastened bud burst. The effect of treatments applied during dormancy development was larger than that of provenance; in some cases no provenance effect was detected, but in 1-year-old seedlings, time to bud burst decreased linearly with increasing latitude of origin. Differences among provenances were complicated by different responses of some origins to light conditions under long-day forcing. In conclusion, timing of bud burst in Norway spruce seedlings is significantly affected by temperature during bud set, and these effects are modified by chilling and environmental conditions during forcing.

In recent years several forest insects have been recorded as newcomers or as more abundant than before towards northern latitudes and higher elevations in Norway. Such observations are from different groups of forest insect, including herbivorous geometrids, phloeophagous bark beetles and insects in cone seed .......
