21. Quality of organically produced wheat from diverse origin
Sammanfattning : The health benefits of organically grown whole grain wheat are derived from various nutritional compounds such as dietary fibre, minerals, vitamins and phytochemicals, while baking quality is influenced by the protein content and composition. Genetic improvement and production of wheat to increase the amounts of the nutritional compounds therefore enhance the health benefits. LÄS MER
22. Forest floor vegetation in Sweden : impacts of intensified forestry, nutrient addition and changes in forest structure
Sammanfattning : In boreal forests, dwarf-shrubs (Vaccinium spp.) often dominate the forest floor and are key-stone species in ecosystems due to their importance for nutrient cycling and as a major food source for herbivores. Forestry affects the vegetation both directly through management and indirectly by altering the forest structure. LÄS MER
23. Environmental protection in Swedish forestry : a study of the implementation process
Sammanfattning : According to the Swedish Forestry Act, environmental protection is required within forest operations regardless of forest ownership. This thesis examines the extent to which regulations issued by the National Board of Forestry are implemented in clearcuttings. LÄS MER
24. Quantitative genetics of wood quality traits in Scots pine
Sammanfattning : Wood quality of commercial tree species is important for many wood processingindustries and thus should be considered for inclusion in forest tree improvementprograms. This thesis evaluated the suitability of various proxy methods for rapid andnon-destructive assessment of wood quality traits on standing trees of Scots pine and thepotential for genetic improvement of different wood quality traits through recurrentselective breeding.

25. Impact of tree species on carbon in forest soils
Sammanfattning : Different tree species differ in productivity, litter quality and quantity, canopy structure and nitrogen deposition. Norway spruce (Picea abies), Scots pine (Pinus sylvestris) and birch (Betula pendula and B. pubescens) are the three dominant tree species in Sweden. LÄS MER
