  1. 1. Assessing the effect of Fusarium graminearum inoculation on the root structure of Swedish winter wheat cultivars (Triticum aestivum

    Master-uppsats, SLU/Dept. of Crop Production Ecology

    Författare :Fayez Altabbaa; [2022]
    Nyckelord :Fusarium graminearum; conidium suspension; hypha agar plug; root architecture traits; root cellar structure traits; shoot traits; genotypes;

    Sammanfattning : Several diseases attack the wheat crop and reduce the yield, such as root disease, which causes a tremendous loss in wheat production. Root rot has a variety of causal agents, such as nematodes, viruses, and bacteria, but the most common pathogens causing wheat root rot are oomycetes and fungi. LÄS MER

  3. 2. Isolation, protocol optimization and screening of genotypes against net blotch and scald of barley in controlled condition

    Master-uppsats, SLU/Dept. of Plant Breeding (from 130101)

    Författare :Rishap Dhakal; [2022]
    Nyckelord :barley; net blotch; scald; isolation; seedling resistance;

    Sammanfattning : Net blotch and scald are two economically important diseases of barley, causing significant losses in yield in Nordic and Baltic states (NBS) countries and in Sweden. Identification and deployment of resistant cultivars is the most effective method for controlling both the diseases. LÄS MER

  4. 3. Odlingsförsök efter Maria Thuns så–kalender. En undersökning av morötter som odlats på de fem kalenderdagarna rot, blad, blom, frukt och ogynnsam dag

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Nilsson Forsström; [2017-01-18]
    Nyckelord :Köksväxtodling; Alternativa odlingsformer;

    Sammanfattning : Despite Maria Thun's 50-year experience and the peer-reviewed studies available, the sowing-calendar is today regarded as highly controversial. In the field of biodynamics the use of this kind of calendar, which takes the moons sidereal cycle in concern when sowing, is somewhat more common and accepted. LÄS MER

  5. 4. Effect of planting density and abiotic conditions on yield of Betula pendula and Pinus sylvestris seedlings in monoculture and mixture

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Jennifer McGuinness; [2014]
    Nyckelord :abiotic environment; Betula pendula; density gradient; Interaction effects; Pinus sylvestris; Planting density; planting composition; seedling yield;

    Sammanfattning : How the yield of mature stands changes in response to factors such as stand composition, planting density and abiotic conditions is a developing topic, and underpins models and generalizations used by forest managers today. However, these generalizations are both the subject of debate and are limited to mature stands, leaving a knowledge gap concerning both mixed species stands and younger stands. LÄS MER

  7. 5. Isolation and evaluation of different wheat-rye translocation lines obtained from a disease resistant double translocation line with 1BL/1RS and 2RL/2BS

    Master-uppsats, SLU/Plant Breeding and Biotechnology (until 121231)

    Författare :Mahbubjon Rahmatov; [2012]
    Nyckelord :C-banding; coleoptile colour; resistance; Simple Sequence Repeats; stem rust; translocation; wheat-rye; yellow rust;

    Sammanfattning : Wheat-rye translocations involving 1RS and 2RL of rye are the most useful sources of genes for disease resistance in wheat breeding. Rye genes are known to control resistance to biotic and abiotic stresses. LÄS MER
