  1. 6. Stump treatment with the root rot antagonist phlebiopsis gigantea : - sensitivity of P. gigantea spores to high pressure stress; - reduced water consumption for stump treatment

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Martin Pettersson; [2013]
    Nyckelord :Stump treatment; Heterobasidion annosum; Heterobasidion parviporum; Phlebiopsis gigantea; Picea abies; Rotstop; pressure stress; water consumption;

    Sammanfattning : Stump treatment today requires large quantities of clean water mixed with the protective product Rotstop, to fully cover the stump surface. In order to reduce the water consumption without reducing the coverage of the stump surface, the pressure in the stump treatment device can be increased. Therefore, the Phlebiopsis gigantea (Fr.)

  3. 7. Comparative analyses of Defense gene expression in Norway spruce sapwood

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

    Författare :Sophie Rommel; [2012]
    Nyckelord :Norway spruce; Sapwood; Gene expression;

    Sammanfattning : As the most important species in Europe’s forest industry, Norway spruce [Picea abies (L.) Karst.] has a very high economical impact. Unfortunately, the forest industry has yearly losses of approximately 800 million euro, because many Norway spruce stands suffer infection by one of the tree’s major pathogens Heterobasidion parviporum (Fr.

  4. 8. Infection preference of Heterobasidion annosum s.s. and H. parviporum on sapwood and heartwood pine and spruce stumps

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

    Författare :Maria Bernat; [2011]
    Nyckelord :Heterobasidion spp; Picea abies; Pinus sylvestris; Infection; Sapowood;

    Sammanfattning : Important losses in forest production are caused by fungi of the genus Heterobasidion in the Scandinavian region. After thinning, spores germinate on the surface of stumps, they infect the root system and they spread to neighbouring trees through root contacts. LÄS MER

  5. 9. Efficacy of Phlebiopsis gigantea treatment on spore infections of Heterobasidion spp. on Larix X eurolepis

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Erik Ek; [2011]
    Nyckelord :Root rot; hybrid larch; Larix x eurolepis; stump treatment Phlebiopsis gigantea;

    Sammanfattning : The effectiveness of Phlebiopsis gigantea to prevent spore infections from Heterobasidionannosum and Heterobasidion parviporum on hybrid larch stumps were investigated in fivestands in southern Sweden. All sites are former forest land and the age of the trees wasbetween 9 and 13 years. LÄS MER

  7. 10. 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
