  1. 16. Heterobasidion spp presence in young pine plantations in southern Sweden

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Sarah Louise Gore; [2023]
    Nyckelord :Heterobasidion; Scots pine; Pinus Sylvestris; Sweden;

    Sammanfattning : Heterobasidion species cause great economic loss the forest industry in the northern hemisphere. The spread of infection takes two forms, the first is an airborne infection and the second is a vegetative infection from infected root to healthy root. Much research has been done concerning the Heterobasidion pathogen. LÄS MER

  3. 17. Jämförelse av patogenprevalens hos vilda humlor på olika avstånd från honungsbisamhällen : och skillnader i patogenförekomst mellan olika arter av kommersiella pollinerare

    Kandidat-uppsats, SLU/Dept. of Ecology

    Författare :Julia Carlsson; [2023]
    Nyckelord :Apis mellifera; Bombus terrestris; vilda pollinerare; patogenprevalens;

    Sammanfattning : Idag minskar den inhemska populationen av pollinerare till följd av klimatförändringar och urbanisering. För att bibehålla den livsviktiga pollineringen används bland annat samhällen av honungsbin (Apis mellifera), vilket antas kunna påverka de vilda humlorna negativt genom exempelvis konkurrens om resurser och patogenspridning.

  4. 18. The effect of heat and UVC treatments on seed germination and seed-borne fungi of Pinus sylvestris, Pinus contorta and Pseudotsuga menziesii used in Swedish nurseries

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Wiktoria Breza; [2023]
    Nyckelord :seed-borne pathogens; artificial regeneration; conifers; thermotherapy;

    Sammanfattning : Pathogen free seeds are critical to produce healthy plants for forest regeneration. However, recent studies have shown that tree seed carry a high diversity of fungi including known and unknown pathogens. LÄS MER

  5. 19. Fungicide tolerance in Phytophthora infestans

    Master-uppsats, SLU/Dept. of Forest Mycology and Plant Pathology

    Författare :Nadja Kvick Nastaj; [2023]
    Nyckelord :Phytophthora infestans; Fungicide tolerance; Fungicide dose;

    Sammanfattning : For the last 180 years, the pathogen P infestans, responsible for the late blight disease, has been a severe problem for farmers. Despite the large efforts and financial investments done in the management of the disease, 15-30% of the potato production is lost to this disease globally each year. LÄS MER

  7. 20. Effect of a plant-derived nutraceutical on the tolerance of axenically-cultured Artemia towards abiotic or biotic stressor

    Master-uppsats, SLU/Dept. of Animal Breeding and Genetics

    Författare :Ahumuza Allan Castro; [2023]
    Nyckelord :Artemia; Hsp70; Vibrio campbellii; plant extract; aquaculture; abiotic stressor;

    Sammanfattning : Aquaculture is one of the fastest-growing food-production industries worldwide accounting for almost half of fish used for human consumption. Super-intensive, intensive, and semi-intensive farming practices used to produce large farm fish are increasing the frequency of disease outbreaks which is a major problem affecting sustainable aquaculture growth.
