  1. 11. 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

  3. 12. 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

  4. 13. Temperature requirement for germination of conidiospores and growth of mycelia of Heterobasidion annosum s.s. and Heterobasidion parviporum

    L3-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Jasmin Taubert; [2008]
    Nyckelord :conidiospores; germination; growth; heterobasidion annosum; H. parviporum; temperature;

    Sammanfattning : Different temperature requirements of the two species Heterobasidion annosum (Fr.) Bref. (P group) and H. parviporum Niemelä & Korhonen (S group) should explain why the distribution areas are different in Scandinavia despite of a wide range of distribution of their host species Picea abies and Pinus sylvestris up to 68°N.

  5. 14. Efficacy of different concentrations of Rotstop® and RotstopS and imperfect cover of RotstopS against Heterobasidion spp. infections on Norway spruce stumps

    L3-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Evgeny Sidorov; [2005]
    Nyckelord :Rotstop; spruce;

    Sammanfattning : The effectiveness of treatment with two Phlebiopsis gigantea based preparations (Rotstop® and RotstopS) in different concentrations against the root and butt rot causing fungus Heterobasidion annosum s.l. on Norway spruce (Picea abies) thinning stumps in southern Sweden was compared.

  7. 15. Presence of Heterobasidion annosum and the need for stump treatment in monocultures of Scots pine in southern Sweden

    L3-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Eglė Petrylaitė; [2004]
    Nyckelord :heterobasidion annosum; stump treatment; monocultures of Scots pine; pinus sylvestris L.;

    Sammanfattning : The incidence of Heterobasidion spp. in the roots of Scots pine (Pinus sylvestris L.) was investigated in fifteen monocultures of Scots pine in southern Sweden. On the basis of crown condition, all trees were divided into four classes from healthy to dead trees on a number of sample plots at each site. LÄS MER
