  1. 21. Pinus contorta susceptibility to Heterobasidion spp. : a study of stumps, roots and artificial spore infections of stumps

    Magister-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Susanne Svensson; [2011]
    Nyckelord :Lodgepoole pine ; Pinus contorta; root rot; Heterobasidion spp;

    Sammanfattning : The Lodgepole pines susceptibility to Heterobasidion spp. was investigated in three parts ofthis study. In the first part, discs from freshly cut stumps were collected and analyzed to seeif the fungi can spread and grow naturally in Lodgepole pine stands. LÄS MER

  3. 22. Precommercial thinning stumps' susceptibility to Heterobasidion spp. : a comparison between high and low Norway spruce and birch stumps : a measuring of the efficacy of Phlebiopsis gigantea stump treatment

    Magister-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Rebecka Mc Carthy; [2011]
    Nyckelord :pre-commercial thinning stumps; heterobasidion spp; phlebiopsis gigantea stump treatment;

    Sammanfattning : Each year, Heterobasidion spp. is a major cause of economic losses to forestry in the northern hemisphere, including Sweden. New results indicate that pre‐commercial thinnings could be at risk for Heterobasidion spp. infections. LÄS MER

  4. 23. Reliability of Rotfinder instrument for detecting decay in standing trees

    Magister-uppsats, SLU/Dept. of Forest Mycology and Plant Pathology

    Författare :Carmen Romeralo; [2010]
    Nyckelord :rotfinder instrument; decay; non-destructive; standing trees; heterobasidion spp.;

    Sammanfattning : A wood decay detecting instrument, Rotfinder® was evaluated for its accuracy, sensitivity and specificity in detecting decay in standing trees. Five hundred trees were measured in three different stands with Rotfinder at three heights in the stems. The trees were felled and sectioned, and presence or absence of decay was observed for each section. LÄS MER

  5. 24. Identification of proteins expressed by the root-rot fungus Heterobasidion annosum when growing on lignocellulose

    Master-uppsats, SLU/Dept. of Molecular Biology (until 131231)

    Författare :Xiaoyu Wang; [2009]
    Nyckelord :Heterobasidion annosum; peptide mapping; lignocellulose; cellulase; cellobiohydrolase; wood degradation; white-rot fungus;

    Sammanfattning : The Root-rot fungus, Heterobasidion annosum, is a major pathogen on spruce and pine trees and is estimated to cause up to 20 % production loss in the forest industry in the temperate region. The genome of H. annosum has recently been sequenced and a total of ~280 carbohydrate-active enzymes have been predicted so far. LÄS MER

  7. 25. Stubbehandling med pergamentsvamp och urea mot sporinfektioner av rotticka i bestånd av hybridlärk

    Magister-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Henrik Pålsson; [2009]
    Nyckelord :Rotröta; Heterobasidium; Hybridlärk ; Stubbehandling; Pergamentsvamp; Urea;

    Sammanfattning : Root rot is a big hurter and a huge economic problem for the Swedish and European forestry. The severest hurter is Heterobasidion annosum (Fr.) Bref and it occurs as two different species in Sweden. Commonly referred to as the P-type (Heterobasidion annosum s. LÄS MER
