  1. 6. Frost hardiness of grapevine cultivars as affected by ground cover under Scandinavian conditions

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

    Author : Magdalena Jansson; [2013]
    Keywords : frost hardiness; grapevine; ground cover; Scandinavia;

    Abstract : 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).

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

    University essay from SLU/Dept. of Forest Ecology and Management

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

    Abstract : 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. READ MORE

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

    University essay from Molekylär genetik

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

    Abstract : 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]. READ MORE

  5. 9. Frost hardiness of some New Zealand shrubs

    University essay from SLU/Horticulture

    Author : Sture Bengtsson; [2007]
    Keywords : frost; frost hardiness; frost resistance; freezing tolerance; freezing resistance; winter hardiness; cold hardiness; freeze test; frost injury; frost injury assessment; cold acclimation; new zealand shrubs; new zealand flora; plant stress physiology; electrolyte leakage; index of injury; LT50; visual injury assessment; olearia; coprosma; podocarpus; buxus; taxus;

    Abstract : Frost resistances, LT50, were decided for stems and leaves of several New Zealand woody plants belonging to Olearia (Asteraceae), Coprosma (Rubiaceae) and Podocarpus (Podocarpaceae). That was part of the aims, which included trying to find species potentially winter hardy in southern coastal Sweden and study methods for frost hardiness assessment. READ MORE

  6. 10. Alternativa stråbränslen i växtföljden

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Gustaf Blomqvist; [2006]
