  1. 11. Nodulation and biomass development of yellow and blue lucerne under pH stress

    University essay from SLU/Dept. of Crop Production Ecology

    Author : Katarina Boström; [2023]
    Keywords : lucerne; blue lucerne BL ; yellow lucerne YL ; E. meliloti; nodulation; pH;

    Abstract : Approximately 77% of global arable land use is devoted to forage cultivation, which is the basis for animal production and global food security. Therefore a sustainable and biologically diverse forage cultivation is needed. Feed for cattle needs to contain a good balance between fibre, energy and protein. READ MORE

  3. 12. Effects of soil factors on pioneer bryophyte species composition

    University essay from Lunds universitet/Examensarbeten i biologi

    Author : Dora Mijić; [2023]
    Keywords : Biology and Life Sciences;

    Abstract : Bryophytes play a significant role in various ecological processes, including soil succession and colonization after disturbances. Although they are commonly believed to take up nutrients from soil solutions rather than the soil itself, the influence of soil on their growth and distribution is evident from previous studies.

  4. 13. Mykorrhiza i sandbäddar

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

    Author : Emma Tabell; [2023]
    Keywords : odling; symbios; Glomus; Glomeromyceter; arbuskulär mykorrhiza; rotsvampar; sand; Mucoromycotina;

    Abstract : Syftet i denna studie var att undersöka om arbuskulär mykorrhiza förekommer hos Klinta trädgård där perenna växtslag odlas i sandbäddar. Sand är naturligt näringsfattig och ingen gödsling görs på odlingen vilket kan påverka växternas etablering på platsen. READ MORE
