  1. 11. Adapting Scots pine Regeneration to the Changing Climate : An investigation of the effects of seed coating, arginine addition, and planting position

    Författare :Matej Domevscik; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : In Sweden, new forest stands have long been artificially regenerated using conifer seedlings. While standardized and widely adopted, this approach may need to be further adapted to the predicted increases in variations in the weather, such as extended periods of drought. LÄS MER

  3. 12. Genetic diversity and nutritional content of sorghum [Sorghum bicolor (L.) Moench] accessions from Southern Africa

    Författare :Tiny Motlhaodi; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Sorghum [Sorghum bicolor (L.) Moench] is an important cereal crop in semi-arid regions of the world especially in Africa, South Asia and China. It is an important food and fodder crop in the semi-arid tropics (SAT) of Africa, where it is used for making different kinds of food. LÄS MER

  4. 13. Nutrient balance and salinity stress in arbuscular mycorrhizal fungi

    Författare :Edith Hammer; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inoculum; Glomalin; Fatty acids; Osmolyte; Organic matter; K; Na; Salinity; Symbiotic exchange; Phosphorus P; Carbon C; PIXE; Arbuscular mycorrhizal fungi; Rhizobium;

    Sammanfattning : Earth’s primary production depends to a considerable extent on the mycorrhizal symbiosis, since mycorrhizal fungi supply their host plant with important mineral nutrients. I examined the influence of different nutrient regimes on the fungal partner in the arbuscular mycorrhizal symbiosis. LÄS MER

  5. 14. Thin water and ice films on minerals : a molecular level study

    Författare :Merve Yeşilbaş; Jean-François Boily; Johannes Messinger; Grégory Lefèvre; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; water; ice; cryosalt; minerals; rocks; atmosphere; Dynamic Vapour Sorption; FTIR; cryo-FESEM; fysikalisk kemi; Physical Chemistry;

    Sammanfattning : Minerals in Earth’s crust and suspended in the atmosphere form water or ice films as thin as a few nanometers to as thick as a few micrometers, and beyond. Mineral-bound water and ice films in terrestrial systems (e.g. LÄS MER

  7. 15. Biomass, community structure and phosphorus uptake of ectomycorrhizal fungi in response to phosphorus limitation and nitrogen deposition

    Författare :Juan Pablo Almeida; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phosphorus and nitrogen limitation; nitrogen deposition; ectomycorrhizal fungi; community composition; apatite; Paxillus involutus; Phosphorus and nitrogen limitation; nitrogen deposition; ectomycorrhizal fungi; community composition; apatite; Paxillus involutus;

    Sammanfattning : High levels of nitrogen (N) deposition might result in a transition from N to phosphorus (P) limitation in high latitude forests. Thiscould have fundamental consequences for forest production, nutrient acquisition and nutrient leaching. LÄS MER
