    Abstract : Popular Abstract in Swedish Spatiell struktur hos Corylus avellana (Betulaceae), hassel, med avseende på genetisk och morfometrisk variation Hassel, (Corylus avellana) är en vindpollinerad perenn buske som förekommer i mer eller mindre sammanhängande bestånd i stora delar av Europa. I denna avhandling har jag undersökt den genetiska och morfometriska variationen på olika hierarkiska nivåer hos hassel genom att använda förmodat neutrala karaktärer såsom allozymer och bladform.
