  1. 11. The effect of cold stratification on germination in 28 cultural relict plant species : with the purpose of establishing germination protocols

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

    Författare :Jonatan Leo; [2013]
    Nyckelord :dormancy; germination; stratification; scarification; cultural relict plant;

    Sammanfattning : Cultural relict plant species from the Nordic countries have been collected by the Nordic Genetic Resource Center (NordGen) for the purpose of conservation. To ensure high seed vitality in store, regular germination tests need to be conducted. LÄS MER

  3. 12. Högskärmar och kalhyggesfritt skogsbruk på bördig mark i Medelpad

    Magister-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Elsa Järvholm; [2011]
    Nyckelord :högskärm; gran; föryngring; skador; kontinuitetsskogsbruk;

    Sammanfattning : Under senare år har intresset för ett alternativ till kalhyggesbruk vuxit sig starkare i både Sverige och andra länder i Europa. I Sverige ses skärmskogsbruk och blädning i granskogar som två högst intressanta alternativ till kalhyggesbruk. LÄS MER

  4. 13. Bevare mig väl! Äldre växtsortmaterial ser dagen ljus

    Kandidat-uppsats, Lunds universitet/Humanekologi

    Författare :Lena Gustavsson; [2010]
    Nyckelord :genetic plant diversity; cereals; landraces; in situ conservation; Social Sciences;

    Sammanfattning : Genetic plant diversity is crucial to meet future challenges through plant adaptation to new biotic and abiotic conditions. To date, conservation strategy focuses on an ex situ (off-site) approach whereas the importance of in situ (in-site) conservation has been stressed to increase the public engagement and facilitate the gradual evolutionary adaptation of the material.

  5. 14. Regeneration of threatened indigenous fruit species in Uganda, the case of Parinari curatellifolia

    Master-uppsats, SLU/Swedish Biodiversity Centre

    Författare :Richard Mawula; [2009]
    Nyckelord :Parinari curatellifolia; Mobola; threatened indigenous species; under-utilized fruit tree; regeneration; biodiversity; Uganda;

    Sammanfattning : Indigenous wild fruits and, or underutilised plant species are of high importance for nutrition, beverages, and pharmaceuticals values. They provide invaluable benefits to the entire biosphere: including but not limited to climate regulation in terms of rainfall cycle, oxygen supply and carbon sequestration, and provide fodder to both wild and domestic animal herds.

  7. 15. Maize (Zea mays L.) landraces in eastern Serbia : characterization and the present cultivation

    Master-uppsats, SLU/Swedish Biodiversity Centre

    Författare :Jelena Knežević; [2009]
    Nyckelord :maize; Zea mays; local varieties; characterization; conservation; zein proteins; electrophoresis; field survey; interviews; ethnobotany; Serbia;

    Sammanfattning : The evolutionary value of landraces is immense, especially when bearing in mind the constant diminishment of crop genetic variability and the development of intensive agriculture. The assessment of morphological and agronomic traits of landraces, together with molecular markers, is certainly a good basis for the efforts toward their protection. LÄS MER
