  1. 1. En hållbart intensifierad slåttervall med vitklöver : en litteratursammanställning

    University essay from SLU/Dept. of Crop Production Ecology

    Author : Johanna Forss; [2023]
    Keywords : etablering; kväve; skördesystem; Trifolium repens; vall; vitklöver;

    Abstract : Fördelarna med att inkludera vall i växtföljden är många, till exempel kolinlagring, markförbättrande egenskaper och ogräsbekämpning. Intresset för odling av vall ökar när det finns fler avsättningsmöjligheter och ses som ett medel för att uppnå en hållbar intensifiering av odlingssystemet. READ MORE

  2. 2. SubKluster: Novel method to bin scaffolds from cereal genomes into subgenomes using substring frequency analysis

    University essay from Lunds universitet/Examensarbeten i bioinformatik

    Author : Victor Kalbskopf; [2023]
    Keywords : Biology and Life Sciences;

    Abstract : The genome of the Belinda variety of the hexaploid oat (Avena sativa) has recently been sequenced and assembled. This project aims to improve the assembly by clustering the thousands of scaffolds into their three ancestral subgenomes using Principle Component Analysis (PCA) of kmer and repeat-element frequencies.

  3. 3. Integrating horticultural and arable crops : a sustainable way to increase vegetable production in Scania?

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Stina Helena Mortensen; [2022]
    Keywords : Horticulture; agriculture; vegetables; crop rotation; crop sequence; diversification; integration; ecosystem services; farmers’ attitudes;

    Abstract : Modern arable production is associated with a highly homogenous landscape with few cultivated species and is relying heavily on external chemical inputs. Intensive vegetable production, on the other hand, is associated with environmental costs such as increased risk of nutrient leaching and loss of soil organic matter. READ MORE

  4. 4. Analyses of circular DNA molecules in the leafhopper Psammotettix alienus for identification of viruses and plasmids

    University essay from SLU/Dept. Of Plant Biology

    Author : Jeremiah Sigalla; [2019]
    Keywords : blue dwarf disease; leafhopper; phylogenetic analysis; psammotettix alienus; rolling circle amplification; wheat blue dwarf phytoplasma; wheat dwarf disease; wheat dwarf virus;

    Abstract : Microorganisms often depend on vectors for transmission. A single vector may carry different species of microorganisms such as fungi, bacteria and viruses. In Sweden, leafhoppers of the species Psammotettix alienus are known as a vector of wheat dwarf virus, but they may be carriers of other microorganisms as well. READ MORE

  5. 5. Molecular detection and characterization of begomoviruses from Burkina Faso and Nicaragua

    University essay from SLU/Dept. Of Plant Biology

    Author : Suneel Sekhar Rachapudi; [2019]
    Keywords : geminivirus; begomovirus; Calopogonium mosaic virus; Bean golden mosaic virus; Phaseolus vulgaris; polymerase chain reaction; rolling circle amplification;

    Abstract : Agriculture plays a major role in the economy of countries in Africa and America. Viruses have emerged as major plant pathogens during the last few decades on agriculturally important field crop plants. The genus Begomovirus belongs to the family Geminiviridae, which is the largest family of plant-infecting viruses. READ MORE
