  1. 16. A study of root distribution and the effect of Heterobasidion spp. root infection on the growth of live Scots pines (Pinus sylvestris) in Southern Sweden

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Jing Zhang; [2012]
    Nyckelord :Heterobasidion spp.; Pinus sylvestris; stump treatment; forest management; root morphology;

    Sammanfattning : Stump treatment against Heterobasidion spp. root infection has not been commonly conducted on Scots pine (Pinus sylvestris L.) plantations in Sweden. To assess whether it should be, growth and volume losses caused by H. LÄS MER

  3. 17. Activity and synergistic action on cellulosic substrates of engineered product-site variants of Hypocrea jecorina Cel7A

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

    Författare :Umair Saleem; [2012]
    Nyckelord :cellulase; cellobiohydrolase; lignocellulose; biofuel; protein engineering; biotechnology; thermochemical pretreatment; spruce;

    Sammanfattning : Cellobiohydrolase Cel7A (Hje_Cel7A) from the ascomycete fungus Hypocrea jecorina is the major component of enzyme cocktails for degradation of plant biomass to soluble sugars for conversion to biofuels. It’s active site is enclosed in a cellulose-binding tunnel and it is able to processively cleave off several cellobiose units from the end of a cellulose chain before being released. LÄS MER

  4. 18. 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.

  5. 19. 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

  7. 20. 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
