    Sammanfattning : The here presented PhD project explores the phenomenon of cereal cultivation during the Iron Age (c. 500 BC – AD 1100) in southern Scandinavia. The main body of the thesis consists of four articles. LÄS MER

  3. 2. Vegetation and land-use in the Småland Uplands, southern Sweden, during the last 6000 years

    Författare :Per Lagerås; Kvartärgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geologi; physical geography; Sweden; Geology; Småland Uplands; land-use history; pollen analysis; Holocene vegetation history; mineral magnetic analysis; AMS dating; clearance cairns; hay production; shifting cultivation; Picea migration; slash-and-burn cultivation; fysisk geografi;

    Sammanfattning : Palaeoecological methods were applied to peat and sediment cores recovered from one bog (Bråtamossen) and two lakes (Avegöl and Femtingagölen) in the Småland Uplands, southern Sweden. The general aim was to reconstruct the landuse and vegetation history for the last 6000 years in this agriculturally marginal region. LÄS MER

  4. 3. New potential in old varieties : Using landrace cereal to meet food production challenges

    Författare :Tove Ortman; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Landrace cereals – historical varieties characterised by high genetic diversity – have long been considered obsolete, and have almost completely been replaced by high yielding but high input-dependent cultivars. However, the need for increased multifunctional and low-input farming, and for finding varieties that can be robust to environmental stresses, has meant that these old varieties have been revalued.

  5. 4. Resource efficient control of Elymus repens

    Författare :Björn Ringselle; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Elymus repens is a perennial grass weed that causes great yield losses in a variety of crops in the southern and northern temperate zones. Primary control methods for E. repens are herbicides or intensive tillage, both of which have a number of negative side-effects, e.g. LÄS MER

  7. 5. On Folates in Yeasts -Exploring Yeasts as Vehicles for Biofortification of Folates in Food

    Författare :Sofia Hjortmo; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; yeast; B vitamin; biofortification; bread; indigenous food; Saccharomyces cerevisiae; folic acid; fermented food; togwa; Folate;

    Sammanfattning : High intake of the B vitamin folate during pregnancy is known to decrease the risk for development of neural tube defects. In addition, a good folate status may prevent the progression of several diseases such as megaloblastic anaemia, cardiovascular disease, cancer and Alzheimer’s disease. LÄS MER
