Kjelle avrenningsforsøk. Årsrapport 2022–2023 for jordarbeidingsforsøk på lav erosjonsrisiko
(NIBIO Rapport, Research report, 2024)‘Ingen jordarbeiding om høsten’ har vært et av de viktigste tiltakene mot erosjon og tap av næringsstoffer fra jordbruksarealer siden begynnelsen på 1990-tallet. Avrenningsforsøk som startet på 1980-tallet viser stor effekt ... -
Været i vekstsesongen 2023
(Journal article, 2023)Varierende værforhold og mange rekorder for både temperatur og nedbør har preget været i 2023. Forsommertørke med påfølgende vått vær på ettersommeren ødela mange kornavlinger i sørlige deler av landet, og frukt ble ødelagt ... -
Warmer temperature during asexual reproduction induce methylome, transcriptomic, and lasting phenotypic changes in Fragaria vesca ecotypes
(Peer reviewed; Journal article, 2023-07-31)Plants must adapt with increasing speed to global warming to maintain their fitness. One rapid adaptation mechanism is epigenetic memory, which may provide organisms sufficient time to adapt to climate change. We studied ... -
Methylome, transcriptome, and phenotype changes induced by temperature conditions experienced during sexual reproduction in Fragaria vesca
(Peer reviewed; Journal article, 2023-06-21)Temperature conditions experienced during embryogenesis and seed development may induce epigenetic changes that increase phenotypic variation in plants. Here we investigate if embryogenesis and seed development at two ... -
Novel insight into lepidopteran phylogenetics from the mitochondrial genome of the apple fruit moth of the family Argyresthiidae
(Peer reviewed; Journal article, 2024-01-02)Background The order Lepidoptera has an abundance of species, including both agriculturally beneficial and detrimental insects. Molecular data has been used to investigate the phylogenetic relationships of major subdivisions ... -
Are fungal epizootics a sign of successful biological control of cereal aphids?
(Peer reviewed; Journal article, 2023-07-26)Pandora neoaphidis is a common entomopathogenic fungus on Sitobion avenae, which is an important aphid pest on cereals in Europe. Pandora neoaphidis is known to cause epizootics (i.e. an unusually high prevalence of infected ... -
Comparative Transcriptome Analysis Reveals Novel Candidate Resistance Genes Involved in Defence against Phytophthora cactorum in Strawberry
(Peer reviewed; Journal article, 2023-06-29)Crown rot, caused by Phytophthora cactorum, is a devastating disease of strawberry. While most commercial octoploid strawberry cultivars (Fragaria × ananassa Duch) are generally susceptible, the diploid species Fragaria ... -
Methyl jasmonate, salicylic acid, and oxalic acid affects growth, inducible defenses, and pine weevil resistance in Norway spruce
(Peer reviewed; Journal article, 2023-07-06)The large pine weevil (Hylobius abietis) is a major regeneration pest in commercial forestry. Pesticide application has historically been the preferred control method, but pesticides are now being phased out in several ... -
Massehåndtering og potetcystenematode
(Journal article, 2023)Potetcystenematode (PCN) er en karanteneskadegjører som utgjør en stor risiko for norsk potetproduksjon, både fordi den vil gjøre stor skade og være svært vanskelig å bekjempe ved etablering. For å beskytte norsk potetproduksjon ... -
