    Author : Emelie Melin; [2010]
    Keywords : Community Gardens; brukarmedverkan; urban odling; trygghet; Stadsdelsträdgården; koloniträdgårdar; Mykorrhiza; The Allotment Plot;

    Abstract : This paper originates in a study of Community Gardens in the United States. An overview of how and why the gardens have emerged, their functions today, and their effects and problems is presented. The reader will also be introduced to a selection of Swedish movements that correspond with the phenomenon of the American Community Garden. READ MORE

  3. 22. Inokulering med två hjorttryfflar på arginingödslade täckrotsplantor i Gideå plantskola

    University essay from SLU/Dept. of Forest Mycology and Plant Pathology

    Author : Lisa Edvardsson; [2009]
    Keywords : mykorrhiza; elaphomyces muricatus; elaphomyces granulatus; plantskola; arginin; wallco;

    Abstract : The effect of inoculation on containerized pine and spruce seedlings in a nursery with two ectomycorrhizal fungi was investigated in regard to the development of mycorrhiza and plant growth. The fungi were Elaphomyces muricatus and Elaphomyces granulates and the inoculated seedlings were compared to an uninoculated control. READ MORE

  4. 23. Vegetationslösningar och andra metoder mot stranderosion

    University essay from SLU/Horticulture

    Author : Paul Wallén; [2008]
    Keywords : erosion; vegetation; sandrör; strandråg; strandkvickrot; sandstrand; hövd; strandfodring; Ammophila arenaria; Leymus arenarius; sanddyner; stranderosion; artificiell sandtillförsel;

    Abstract : Today 70 percent of the world's sand beaches are under recession due to erosion. The global warming may have the effect upon the sea level increasing and the erosion increasing on the sand beaches. To save these sand beaches, the erosion must be prevented. READ MORE

  5. 24. Goliatmusseron (Tricholoma matsutake) : kräver den en kontinuitet av träd?

    University essay from SLU/Dept. of Forest Mycology and Plant Pathology

    Author : Lotta Risberg; [2003]
    Keywords : svamp; mykorrhiza; naturvård; kontinuitet; pinus sylvestris; kalavverkning; trädålder; skogshistoria; skogsbruk; Sverige;

    Abstract : Modern forestry management may disadvantage some mykorrhiza forming fungi because; they are dependent on late successions and cannot survive the constantly recurring breaks in the continuity of their host tree. For this study the specie goliatmusseron (Tricholoma matsutake) was chosen to investigate this possibility. In Sweden T. READ MORE

  6. 25. Effects of shade and humus fertility on boreal forest tree seedling growth, competition and mycorrhizal colonisation

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Helena Dehlin; [2001]
    Keywords : far-red light; adaptive plasticity; mineral-nutrition; birch seedlings; Scots pine seedlings; spruce seedlings; regeneration dynamics; mycorrhizal symbioses; soil fertility; interspecific interactions;

    Abstract : In boreal forest ecosystems, growth of tree seedlings is limited by resources both aboveground (through shading) and belowground (through nutrient limitation), and the ability to tolerate or avoid these conditions is important in determining the relative performance of different tree species. Two of the means to compete for these resources, are through increasing stem-elongation to escape shading by neighbours (shade avoidance), and through mycorrhizal symbiosis that may increase the nutrient- and water up-take.
