  2. 1. Life-history traits and population differentiation in a clonal plant: implications for establishment, persistence and weediness

    Author : Johanna Eneström; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; weediness; Clonal plant; resource sharing; resource storage; partitioning of genetic variation; seedling development; seed recruitment; Aegopodium podagraria;

    Abstract : Clonality is wide-spread among plants, and clonal plants dominate many habitats and include many highly invasive species. Clonal growth incurs both advantages and costs and clonal plants often have reduced sexual reproduction compared to non-clonal plants which could be expected to lower genetic variation and hence evolutionary potential.

  4. 2. Within-species variation in grass weeds in Sweden : dormancy, herbicide response, genetic relationships

    Author : Liv Åkerblom Espeby; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Variation within a weed species enables it to persist through varying conditions and is thus an important component of weediness. In this thesis, intra-specific variation in two agronomically important attributes - herbicide susceptibility and seed dormancy - are studied in Swedish Apera spica-venti (L.) Beauv. and Alopecurus myosuroides Huds. READ MORE
