  1. 1. Cost-effective cultivation of lodgepole pine for biorefinery applications

    Författare :Ingegerd Backlund; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The overall objective was to evaluate the scope for the cost-effective cultivation of lodgepole pine (Pinus contorta, PC) stands in a way that would enable early biomass harvesting to supply raw material for biorefineries. Commercial direct seeded PC stands were shown to produce 200 m3/ha of stemwood or 100 tons of d.w. LÄS MER

  3. 2. Quantitative genetics of lodgepole pine (Pinus contorta) wood quality traits in Sweden

    Författare :Haleh Hayatgheibi; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Stem bending, breakage, and general instability of lodgepole pine has been a major problem in northern Sweden due to low stem stiffness. The overall aim of this thesis was to evaluate the potential incorporation of wood quality traits into lodgepole pine advanced breeding programs. LÄS MER

  4. 3. Foliar fungi of Scots pine (Pinus sylvestris)

    Författare :Hanna Millberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Scots pine (Pinus sylvestris) is an ecologically and economically important tree species in Fennoscandia. Scots pine needles host a variety of fungi, some with the potential to profoundly influence their host. These fungi can have beneficial or detrimental effects with important implications for both forest health and primary production. LÄS MER

  5. 4. Silvicultural regimes and early biomass thinning in young, dense pine stands

    Författare :Lars Karlsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The aim of this work was to determine how early management activities in young, dense pine forests affect tree and stand characteristics and profitability and to assess the future potential for tree biomass harvesting and use. In this respect, the long-term effects of corridor pre-commercial thinning (PCT) and thinning on growth and yield were investigated in 11 Scots pine (Pinus sylvestris L. LÄS MER

  7. 5. Pathogens and other threats to Pinus contorta in northern Sweden

    Författare :Margareta Karlman; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pinus contorta; Pinus sylvestris; provenance; weather damage; vole damage; parasitic fungi; Gremmeniella abietina; Phacidium infestans; Sweden;

    Sammanfattning : The background to the large-scale planting of Pinus contorta in northern Sweden is reviewed with an account of the distribution and characteristics ofPi nus contorta within its natural range in western North America. The threatsto successful planting of exotics are discussed in relation to the historicalbackground. LÄS MER
