Effects of mild drought on the morphology of sun and shade needles in 20-year-old Norway spruce trees
(Journal article; Peer reviewed, 2019-02-28)Several studies have looked at how individual environmental factors influence needle morphology in conifer trees, but interacting effects between drought and canopy position have received little attention. In this study, ... -
Forsøk med rumenske granprovenienser Trials with Norway spruce provenances from Romania
(NIBIO-rapport;7(161) 2021, Research report, 2021-10)Denne rapporten presenterer resultater fra fem serier med forsøk der rumenske granpopulasjoner er testet sammen med norske og tyske materialer. Noen av populasjonene var med i flere av forsøksseriene. Den ene serien omfatter ... -
Genetisk variasjon mellom og innen populasjoner av gran i to dalfører i Sør-Norge Genetic variation among and within Norway spruce populations in two valleys in southern Norway
(NIBIO-rapport;7(28) 2021, Research report, 2021-02)Denne studien hadde til formål å karakterisere den genetiske variasjonen i fenologi og vekst mellom og innen granpopulasjoner fra ulike høydelag i to dalfører på Østlandet. Trær fra frø samlet inn på mortrær i naturlige ... -
Genotype by environment interactions for Norway spruce provenances and populations Samspill mellom genotype og miljø for provenienser og populasjonen av gran
(NIBIO-rapport;7(174) 2021, Research report, 2021-11)Denne rapporten presenterer resultater fra forsøk med populasjoner fra Sør-Norge og Trøndelag og med provenienser fra Mellom-Europa og Finland. Både korttidsforsøk plantet på jordbruksmark og feltforsøk i skogen ble plantet. ... -
Hydraulic and mechanical dysfunction of Norway spruce sapwood due to extreme summer drought in Scandinavia
(Journal article; Peer reviewed, 2017-12-22)Projected climate change scenarios such as frequently occurring dry summer spells are an enormous threat to the health of boreal conifer forests. We identified visible features indicating wood with tracheids predisposed ... -
Naturlig utbredelse av gran i Norge
(NIBIO rapport;6(111) 2020, Research report, 2020-09)Litteratur som omhandler utbredelsen til vanlig gran (Picea abies L. Karst.) i Norge er analysert. Rapporten presenterer et nytt utbredelseskart for spontan gran i Norge hvor forekomster i ytterkanten av hovedområdene ... -
Performance in early tests, short-term trials and field trials of selected families of Norway spruce from Svenneby Seed Orchard
(NIBIO-rapport;8(87) 2022, Research report, 2022-05)Norway spruce parents selected from results in progeny trials for testing Svenneby Seed Orchard clones were crossed in a factorial crossing design, and full-sib families were planted in short-term and field trials in ... -
Stem taper and bark functions for Norway spruce in Norway
(Journal article; Peer reviewed, 2019-09-16)Based on data from long-term experimental fields with Norway spruce (Picea abies (L.) H. Karst.), we developed new stem taper and bark functions for Norway. Data was collected from 477 trees in stands across Norway. Three ... -
Successful reproduction and pheromone production by the spruce bark beetle in evolutionary naïve spruce hosts with familiar terpenoid defences
(Journal article; Peer reviewed, 2018-02)1. The European spruce bark beetle Ips typographus is a damaging pest on spruce in Europe. Beetle interactions with tree species originating outside the natural range of the beetle are largely unknown and may be unpredictable ... -
The Ratio between Field Attractive and Background Volatiles Encodes Host-Plant Recognition in a Specialist Moth
(Journal article; Peer reviewed, 2017-12-22)Volatiles emitted by plants convey an array of information through different trophic levels. Animals such as host-seeking herbivores encounter plumes with filaments from both host and non-host plants. While studies showed ... -
Variation among and within provenances of Norway spruce from Trøndelag and Nordland
(NIBIO Rapport;6(10) 2020, Research report, 2020-01)Seedlings from seeds collected in three natural populations of Norway spruce (Picea abies (L. Karst)) in each of 21 provenances distributed between latitudes 63ºN to 66º20’N and altitudes from 25 to 500 m in Trøndelag og ...
