Sometimes there is a point, where an individual landowner decides, it is time to get at least some income by clearcutting the forest. READ MORE

  6. 25. Tritrophic interactions with Silphium integrifolium at the axis : elucidating the role of arbuscular mycorrhizal fungal species on plant phenotype

    University essay from SLU/Dept. of Plant Protection Biology

    Author : Philipp Hansen; [2023]
    Keywords : Arbuscular mycorrhiza; mycorrhizal responsiveness; induced plant volatiles; Silphium integrifolium Silflower ; perennial grains; new crops; ecological intensification;

    Abstract : A fundamental understanding of the intricate interactions between crops and their environment may help guide the development of ecologically intensified agriculture. Arbuscular mycorrhizal fungi (AMF) are root symbionts that can increase a plant’s access to soil resources and have been found to reprogram plant defensive mechanisms, potentially influencing the performance of plant antagonists.
