    Sammanfattning : Idag involveras åtskilliga sektorer inom bioekonomin med skogsråvaran som bas, bland annat sektorer inom textilier, konstruktion, biopharma och kemikalier. Den globala efterfrågan på skogsråvaran är hög. LÄS MER

  3. 2. Modelling the growth of Pinus sylvestris L. monocultures in Sweden depending on the absorbed light

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Mateusz Grzeszkiewicz; [2022]
    Nyckelord :climate change; forest modelling; light use efficiency; photosynthetically active radiation; Scots pine;

    Sammanfattning : Stand growth models are an important aid in contemporary sustainable forest management as a major planning and decision-making tool. However, climate change influencing growth conditions worldwide is a challenge to commonly used empirical models as they do not provide enough flexibility, which can result in inaccurate predictions and thus wrong decisions and sub-optimal results.

    Sammanfattning : The purpose of this study was to determine if fertilization had an impact on the long-term growth effects of pine forest on less fertile ground. It was done by using data from field trials to compare fertilized plots with control plots, and with that get results whether fertilization influences growth or not in a longer period, but also how production and height development acted together.

    Sammanfattning : Nowadays, the changing climate and the risks associated with it urge us to re-evaluate our silvicultural practices. Due to the increasing demand for wood and good economy amongst other factors, Swedish forest landscape is dominated by two species – Norway spruce Picea abies (L.) Karst. and Scots pine Pinus sylvestris (L. LÄS MER

  7. 5. Incidence of Heterobasidion spp.in Scots pine on "low risk" sites in Southern Sweden

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Milda Dambrauskaite; [2019]
    Nyckelord :Heterobasidion annosum; incidence; Scots pine; spore; infection; thinning; Southern Sweden;

    Sammanfattning : Heterobasidion spp. fungi cause pathogenic infections in woody plants throughout the northern hemisphere, causing the most damage in the Boreal forest zone. In Sweden Scots pine, being the second most economically important tree species, suffers a considerable amount of damage as Heterobasidion spp. LÄS MER
