  1. 6. Biologisk nedbrytning av plogsulan : växtföljder, klimat och användningsområden

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

    Författare :Björn Larsson; [2015]
    Nyckelord :bioporer; pålrot; reducerad bearbetning; direktsådd; plogsula; daggmask; miljö; växtnäring; biodiversitet;

    Sammanfattning : Strukturrationaliseringen i jordbruket påverkar i stor utsträckning lantbruksmaskinernas storlek vilket gör att vi går mot allt större och tyngre maskiner. Detta påverkar i stor utsträckning markpackningen. Ett sätt att komma förbi detta är att använda sig av fasta körspår (CTF ). LÄS MER

  3. 7. Modelling vegetation dynamics and carbon fluxes in a high Arctic mire

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Laura Reinelt; [2015]
    Nyckelord :methane dynamics; biogeochemical cycling; vegetation dynamics; ecosystem modelling; LPJ-GUESS; geography; physical geography; high Arctic wetland; Zackenberg; Earth and Environmental Sciences;

    Sammanfattning : High Arctic wetlands are an important component of the global climate system. Nevertheless estimations of their expected response to climate change and associated climate-feedbacks have large uncertainties. Improving models for vegetation and carbon dynamics of ecosystems is an important step towards making predictions more accurate. LÄS MER

  4. 8. Interactions between Rhizobium, antagonistic bacteria and fungal pathogens in faba bean

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

    Författare :Shirin Akhter; [2014]
    Nyckelord :Vicia faba; Beneficial plant bacteria; Fungal pathogens; Antagonism; Interactions;

    Sammanfattning : Plant associated micro-organisms such as nitrogen-fixing Rhizobium, and plant growth- promoting rhizobacteria (PGPR) Pseudomonas spp. and Serratia spp. are well recognised for their vital role in soil fertility and plant health. Most cultivated soils contain large populations of such micro-organisms. LÄS MER

  5. 9. Plasmodiophora brassicae – host and environment interactions

    Uppsats för yrkesexamina på grundnivå, SLU/Dept. of Plant Biology and Forest Genetics (until 131231)

    Författare :Oskar Björling; [2013]
    Nyckelord :clubroot; gene expression; klumprotsjuka; Plasmodiophora brassicae; root exudates; resting spores;

    Sammanfattning : In this thesis, three separate experiments have been performed on different aspects of the interaction between the causal agent of clubroot, Plasmodiophora brassicae, and its hosts. In the first experiment the pathotype of the P. LÄS MER

  7. 10. 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.).
