  1. 11. Påverkar variationer i promotorn till VRN1 frostresistens i vete (Triticum aestivum) från Nordeuropa?

    Kandidat-uppsats, Biologi; Tekniska högskolan

    Författare :Olof Rundquist; [2013]
    Nyckelord :frostresistens; FR-1; Promotorsekvens; Triticum aestivum; Vernalisering;

    Sammanfattning : Vete, Triticum aestivum är en mycket viktig matgröda. Under historiens gång har arten fått anpassa sig till många vitt skilda miljöer. I Nordeuropa har frost-resistens varit extra viktigt. En viktig gen för frostresistensen är VRN1som kontrollerar vernaliseringen d. LÄS MER

  3. 12. Frost hardiness of grapevine cultivars as affected by ground cover under Scandinavian conditions

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

    Författare :Magdalena Jansson; [2013]
    Nyckelord :frost hardiness; grapevine; ground cover; Scandinavia;

    Sammanfattning : Cultivation of grapevine is novel under Scandinavian conditions. We studied the impact of ground cover on frost hardiness of grapevine cultivars in Northwestern Scania in a two-factorial trial with four cultivars Solaris, Pinot Gris, Siegerrebe, Ortega and three kinds of ground cover (open soil, plastic cover and gravel).

  4. 13. Terrasstabilisering - frostbeständigheten i stabiliserade jordar

    Kandidat-uppsats, Lunds universitet/Utbildningar i Helsingborg

    Författare :Niklas Pettersson; André Blohmé; [2012]
    Nyckelord :terrasstabilisering; frost; bindemedel; beständighet; tryckhållfasthet; Technology and Engineering;

    Sammanfattning : The thesis examines various stabilised soils resistance to frost and to increase understanding in the field. By variation of soil materials, binders and water content, the expectation is to find a link between the various factors and frost resistance. LÄS MER

  5. 14. Klibbalens gödslingseffekt på volymproduktionen i ett blandbestånd av gran och klibbal : en simulering i Heureka

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

    Författare :Therese Andersson; Ronja Jägbrant; [2012]
    Nyckelord :kväve; kvävefixering; blandskog; blandskogseffekt; Picea abies; Alnus glutinosa; StandWise; biologisk gödsling;

    Sammanfattning : A secondary and a pioneer tree species can with advantage be included in a mixed stand to increase the use of sunlight. Nitrogen-fixing plants have been shown to increase the supply of nitrogen in the soil by, for example, litter fall. This deposition acts as a biological fertilization, which may be used by non-fixing plants. LÄS MER

  7. 15. The molecular genotyping of flower development genes and allelic variations in ‘historic’ barley accessions

    Magister-uppsats, Molekylär genetik

    Författare :Selcuk Aslan; [2010]
    Nyckelord :Cultivated barley; VRN-1; VRN-2; VRN-3 HvFT ; Ppd-H1; CO; Vrs1; vernalization; photoperiod response; frost resistance; flowering time; sequencing; PCR; aged DNA;

    Sammanfattning : This is a genetic study of flowering time in cultivated barley with the aim to identify the alleles contributing to rapid flowering and frost resistance. We have genotyped a collection of 23 historic barley varieties for the crucial genes [VRN-1, VRN-2, VRN-3 (HvFT), Ppd-H1, CO, and Vrs1]. LÄS MER
