  1. 1. Beware of your neighbour : the effects of intraspecific interactions and CO2-level on the plant growth of two Barley cultivars

    Kandidat-uppsats, SLU/Dept. of Plant Protection Biology

    Författare :Nadja Nyberg; [2023]
    Nyckelord :Barley; Salome; Fairytale; cultivar mixture; pure stand; intraspecific competition; plant-plant interactions; competitive ability; elevated CO2;

    Sammanfattning : Plants have evolved several ways to sense what is going on around them. They can detect possible competitors by picking up on airborne Volatile Compounds emitted from neighbouring plants. The cues can induce growth responses that enhances the competitive ability of the receiver. LÄS MER

  3. 2. Växt-växtbaserad kommunikation : hur sortblandningar påverkade tillväxten hos vårkorn

    Kandidat-uppsats, SLU/Dept. of Ecology

    Författare :Alexander Pettersson; [2021]
    Nyckelord :allelobios; allelopati; flyktiga organiska substanser; vårkorn;

    Sammanfattning : Växter utgör grunden för många ekosystem och näringskedjor. Som platsbundna organismer behöver växter kunna anpassa sig efter de rådande förutsättningarna kring växtplatsen. Växter anpassar sig inte bara efter abiotiska faktorer, utan även stress från skadegörare och andra växter spelar en stor roll för en växtens överlevnad. LÄS MER

  4. 3. The role of terpenes produced by Brassica napus in interactions with Verticillium longisporum

    Master-uppsats, SLU/Department of Plant Biology (from 140101)

    Författare :Alessandra Ruffino; [2020]
    Nyckelord :Verticillium longisporum; terpenes; Brassica napus; Arabidopsis thaliana;

    Sammanfattning : Verticillium longisporum is responsible for severe yield losses, especially of oilseed rape (Brassica napus). Rapeseed is the third most important source of vegetable oil worldwide. The need to increase rapeseed oil yield is not only because is a source of healthy vegetable oil but also because it is used as a biodiesel. LÄS MER

  5. 4. Plant-plant communication - possible mechanisms and benefits

    Kandidat-uppsats, SLU/Dept. of Ecology

    Författare :Maria Hedsén; [2019]
    Nyckelord :plant-plant communication; plant interactions by VOC; plant interactions by sound; photomorphogenesis; thigomorphogenesis; bioacoustics;

    Sammanfattning : Plants interact with their environment in many ways. They can emit and receive volatile organic compounds (VOC) and sound. They can reflect specific wavelengths of light and detect these light signals, reflected by other plants. They can also feel when they are touched and distinguish different types of touch. LÄS MER

  7. 5. Plant chemical signalling affecting aphid-plant interactions

    Magister-uppsats, SLU/Horticulture (until 121231)

    Författare :Erika Qvarfordt; [2009]
    Nyckelord :plant-plant interactions; barley; aphids; root exudates; induced defence;

    Sammanfattning : Aphid-plant interaction are complex processes where much still remains to be explored. This project tested the capacity of aphid-infested barley, Hordeum vulgare (L.), to induce defencelike responses in neighbouring plants via chemical signals, making them less acceptable to the bird cherry-oat aphid Rhopalosiphum padi (L.).
