1. Impact of nitrogen availability and nitrogen structural composition on fungal enzymatic activity and growth : how nutrient availability governs response and development of three saprotrophic Basidiomycetes
Master-uppsats, SLU/Dept. of Soil and EnvironmentSammanfattning : Fungi excrete a wide variety of extracellular enzymes to scavenge for nutrients, such as the often scarce yet essential nutrient nitrogen. All fungi produce highly specialized hydrolytic enzymes, e.g. peptidases, that depolymerize organic molecules. LÄS MER
2. Forest fertilization does not cause any long-term effects on tree growth or vegetation composition
Master-uppsats, SLU/Dept. of EcologySammanfattning : Forest fertilization is considered one of the most effective management options to improve forest productivity. In Fennoscandia, nitrogen (N) fertilization has been practiced for over 50 years and is normally added in the form of granules of NH4NO3 at least 15 years prior to the final harvest. LÄS MER
3. Effect of Mycorrhizal Inoculation on Growth and Nutrient Uptake by Leek (Allium porrum) fertilized with Inorganic N Combined with Saturated Polonite
Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)Sammanfattning : The continuous rise in global population continues to increase the demand for food. Meeting this rise in demand requires an increase in agricultural input, such as applying fertilizers, including phosphorus (P). LÄS MER
4. Fungal Effects on Tree Growth in a Primary Succession
Kandidat-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : In the Boreal zone, ectomycorrhiza is the most common mycorrhiza found among trees and helps with nitrogen and nutrient uptake. Most research on mycorrhiza, its effect, and community development are done on secondary succession (succession in an ecosystem after a disturbance) such as after a clearcut. LÄS MER
5. Biological control of verticillium stem striping disease on oilseed rape : fungi as friends and foes
Kandidat-uppsats, SLU/Dept. of Forest Mycology and Plant PathologySammanfattning : The cultivation of oilseed rape faces challenges caused by pests and pathogens, and soil-borne pathogens such as Plasmodiaphora brassicae (clubroot) are among the main causes of disease. Verticillium longisporum is another soil-borne pathogen, which causes the verticillium stem striping disease in Brassica plants, including oilseed rape. LÄS MER
