    Sammanfattning : Norway spruce [Picea abies (L.) Karst.] is a main tree species in European forests and is important both ecologically and economically. The root rot fungus Heterobasidion annosum sensu lato (s. LÄS MER

  2. 2. Chemical defence in Norway spruce

    Författare :Marie Danielsson; Anna-Karin Borg-Karlson; Anders Backlund; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; volatiles; terpenes; green leaf volatiles; stilbenes; stress response; nepetalactone; Picea abies; Hylobius abietis; Cinara pilicornis; Oligonychus ununguis; Heterobasidion annosum; Chemistry; Kemi;

    Sammanfattning : Norway spruce (Picea abies) responds to stress by biosynthesis of chemical substances, which can deter invading insects or pathogens. Some of these substances are volatile and can be emitted to the surroundings while others are accumulated within the tree. LÄS MER

  3. 3. Microbes Associated with Hylobius abietis : A Chemical and Behavioral Study

    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Hylobius; Ewingella; Penicillium; Heterobasidion; Bacteria; Fungi; Bark; Forest waste; Metabolites; Styrene; Methyl salicylate.;

    Sammanfattning : This thesis is based on three inter-related studies: the first part deals with the microbial consortium, the identification of microbes and their volatiles, the second part deals with the study of bio-chemical control methods of two conifer pests; the pine weevil Hylobius abietis (L.) and the root rot fungi Heterobasidion spp. LÄS MER

  4. 4. Induced defence responses in Picea abies triggered by Heterobasidion annosum s.l

    Författare :Jenny Arnerup Christiansson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; AGRICULTURAL SCIENCES;

    Sammanfattning : Norway spruce [Picea abies (L.)Karst.] is a key tree species for forest industry in Europe and stem and butt rot caused by Heterobasidion parviporum (Fr.) Niemelä & Korhonen is one of its major disease problems. LÄS MER

  5. 5. Understanding virulence of Heterobasidion annosum s.l., a root rot pathogen of conifers

    Författare :Yang Hu; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; AGRICULTURAL SCIENCES;

    Sammanfattning : Heterobasidion annosum sensu lato (s.l.) species are destructive pathogens causing root and butt rot in conifers. The species complex consists of five species: H. LÄS MER
