  1. 1. Arbuscular mycorrhizal fungi in spring wheat : impact of waste-based fertilizers

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Soil and Environment

    Författare :Julia Dahlqvist; [2018]
    Nyckelord :digestate; ash; Cd; cadmium; circular economy; phosphorus; Glomeromycota; quantitative polymerase chain reaction; qPCR; microscope; field; pH; Quarna;

    Sammanfattning : Phosphate rock is a diminishing source of phosphorus (P) for crop production. Other sources are being investigated to replace it, for example bio-ash from wood combustion and biogas digestate from house hold wastes. Ash and digestate application have resulted in increased yields, but the effect on the soil biota has been somewhat varied. LÄS MER

  2. 2. Förekomsten av mörkt, fast och torrt (DFD) nötkött i Sverige : faktorer som påverkar uppkomsten av kvalitetsdefekten

    Kandidat-uppsats, SLU/Department of Molecular Sciences

    Författare :Sanna Pasanen; [2018]
    Nyckelord :slakt; köttindustri; stressfaktorer; storboskap; köttkvalitet; nötkreatur; djurskydd;

    Sammanfattning : Denna studie behandlar kvalitetsdefekten Dark, firm and dry (DFD) i nötkött. Det är ett tillstånd som uppkommer i slaktkroppen post mortem och gör köttet mörkt, fast och torrt. Defekten är ett resultat av en kraftig förbrukning av glykogen i skelettmuskulaturen innan slakt som en respons på kronisk eller långtidsstress. LÄS MER

  3. 3. Induction of plant defence and secretion of volatile compounds by Colletotrichum acutatum in leaf infection assay of woodland strawberry

    Kandidat-uppsats, SLU/Department of Biosystems and Technology (from 130101)

    Författare :Joubin Haji Mirza Ali; [2018]
    Nyckelord :Plant Defence; PAMP-triggered immunity; Colletotrichum acutatum; Anthracnose Disease; Pathogen; Fragaria vesca; Woodland Strawberry; Leaf Infection; Volatile Secretion; β-caryophyllene;

    Sammanfattning : Consumers demand healthy food with less residues of pesticides, in addition to the global awareness of the negative impact such chemicals have caused to the environment during the last decades. Farmers and other agricultural participants are far away from completely end up the usage of pesticides but currently used practice could stepwise be improved in pest management. LÄS MER

  4. 4. Effects of wolf predation risk on community weighted mean plant traits in Białowieża Primeval Forest, Poland

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Jone Lescinskaite; [2018]
    Nyckelord :red deer; wolf; bison; browsing; plant traits; landscape of fear;

    Sammanfattning : It is still largely unknown what effect does wolf risk have on the lower trophic levels in Europe. In the last European lowland forest these interactions were explored with a main browser species – red deer (Cervus elaphus), and other four less common ungulate species, one of which is European bison (Bison bonasus).

  5. 5. Development of expression markers for reduced susceptibility in Fraxinus excelsior

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

    Författare :Matilda Stein Åslund; [2018]
    Nyckelord :Fraxinus excelsior; European ash; Common ash; Molecular markers; Expression markers; Ash dieback disease; Hymenoschyphus fraxineus;

    Sammanfattning : Common ash (Fraxinus excelsior) extends throughout temperate Europe, and in southern and central Sweden it is one of the most common broad-leaved deciduous trees. It is economically valuable thanks to its elastic, hard and pressure-resistant wood, and pollarded ash trees provide a cultural heritage in many European landscapes. LÄS MER
