  1. 1. Comparison of native and introduced tree species in a range from low to high productivity sites in southern Sweden

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Gailene Brazaityte; [2023]
    Keywords : introduced tree species; low productivity sites; moderate productivity sites; high productivity sites; Picea abies; Pinus sylvestris; Betula pendula; Picea glauca; Picea mariana; Picea sitchensis; Pinus contorta; Pseudotsuga menziesii; Abies grandis; Populus balsamifera; Larix x eurolepis; Populus tremula × Populus tremuloides;

    Abstract : The dilemma of climate change, biodiversity conservation and economic efficiency in nowadays forestry leads us to search for the new solutions. Introduction of non-native tree species becomes a more frequently explored field as a solution for the future problems. READ MORE

  3. 2. Thermally modified hybrid aspen : adding value to fast growing broadleaved species in Northern Europe

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Joel Pihlak; [2021]
    Keywords : thermally modified wood; wood quality; short-rotation forestry; Hybrid aspen; European aspen; Populus tremula x tremuloides;

    Abstract : This thesis is focused on thermal modification of hybrid aspen (Populus tremula L. x Populus tremuloides Michx.), its mechanical properties, wood defects and potential use in construction. In the recent years, wood as a building material has become increasingly popular. READ MORE

  4. 3. Hybridaspens utveckling på skogsmark : en studie av bestånd planterade efter stormen Gudrun

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Elin Anander; [2017]
    Keywords : Hybridasp; beståndsutveckling; tillväxt; Götaland; Södra skogsägarna; Södra; dissolvingmassa;

    Abstract : Hybridaspen (Populus tremula x Populs tremuloides) har på grund av dess snabba initiala tillväxt en hög produktionspotential vilket har bekräftats i Södra Sverige, där tillväxtnivåer på 20m3sk per hektar och år under en 25-årig omloppstid har uppmätts. Samtidigt har trädslaget fördelaktiga egenskaper lämpliga till dissolvingmassa, ett massasortiment som nyttjas för vidare tillverkning av textilier, och som idag produceras vid Södra skogsägarnas massabruk i Mörrum.

  5. 4. Nutrient cycling by the herbivorous insect Chrysomela tremulae : Nutrient content in leaves and frass and measurements of ingestion, egestion and exuviation rates

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Sara Andersson; [2016]
    Keywords : Insect herbivory; nutrient cycling efficiencies; approximate digestibility; Chrysomela tremulae; increased C:N;

    Abstract : Insect herbivory on forest canopies strongly affects ecosystem nutrient cycling and availability in a variety of ways, e.g. by changing the quantity, quality and timing of nutrient input to forest soils. READ MORE

  6. 5. Subcellular localization of a Netrual Invertase from hybrid aspens (Populus tremula x tremuloides)

    University essay from SLU/Dept. of Forest Genetics and Plant Physiology

    Author : Marcus Andersson; [2014]
    Keywords : developing wood; localization; hybrid aspen; localization; Neutral Invertase; populus;

    Abstract : Neutral Invertases are sucrose hydrolyzing enzymes whose role in plants remains to be understood. This thesis focuses on the subcellular localization of a neutral invertase from hybrid aspen (Populus tremula × Populus tremuloides), which shows increased transcript levels during secondary cell wall formation.
