  3. 2. Foliar fungal communities of naturally regenerated and nursery-produced Scots pine (Pinus sylvestris) seedlings

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

    Author : Sara López Fernández; [2023]
    Keywords : Endophytes; high-throughput sequencing; foliar fungi; forest nursery; fungal community; fungal pathogens; metabarcoding; mycobiome; Pinus sylvestris; pine seedlings; Scots pine needles;

    Abstract : Endophytic fungal communities living in leaves of trees can have a significant impact on their hosts,showing both beneficial and detrimental effects. Some mutualistic fungal species protect the host against pathogens or herbivores, while pathogenic species can increase the vulnerability of the host against biotic and abiotic stresses. READ MORE

  4. 3. Fungal Effects on Tree Growth in a Primary Succession

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

    Author : August Hedberg; Julian Säflund; [2023]
    Keywords : primary succession; succession; ectomycorrhiza; saprotroph; tree growth; Pinus sylvestris; soil fungi;

    Abstract : 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. READ MORE

  6. 5. En jämförelse av föryngringsmetoderna mekanisk sådd av tall och naturlig föryngring av tall

    University essay from SLU/School for Forest Management

    Author : Felix Johansson; Soeren Meyer-Bothling; [2023]
    Keywords : höjdskillnad; Pinus sylvestris; återbeskogning;

    Abstract : Föryngring med mekanisk sådd och naturlig föryngring är välbeprövade föryngringsmetoder i svenskt skogsbruk och uppgår idag till tre respektive åtta procent av den totala föryngringsarealen. För att ge en god kvantitativ effekt på plantornas överlevnad och höjdtillväxt används det i stor omfattning någon form av markberedning för att blottlägga mineraljorden och skapa en bättre groningspunkt för plantan.
