Genetic Conservation of Forest Trees in the Nordic countries

Gunnar Friis Proschowsky, Mari Rusanen, Mari Mette Tollefsrud, Aðalsteinn Sigurgeirsson et autres

The importance of conservation of forest genetic resources is widely recognized and efforts are needed on national, Nordic, European and global levels. The Nordic countries cooperate on exchanging ...

Access and rights to forest genetic resources in the Nordic region

Tor Myking, Morten Walløe Tvedt, Øyvind Meland Edvardsen, Henrik R. Hallingbäck et autres

Continued flexible exchange of forest genetic resources (FGR) in the Nordic region is important for sustainable forest management and for climate change adaptation and mitigation. For this reason, a high level political initiative identified a need to clarify the legal status of …

Bud dormancy release in elm (Ulmus spp.) clones--a case study of photoperiod and temperature responses

Luisa Ghelardini, Alberto Santini, Sanna Black‐Samuelsson, Tor Myking et autres

Dormancy release as influenced by duration of outdoor winter chilling in Florence (Italy) was studied under different photoperiodic and temperature treatments in collected twigs of two European (Ulmus glabra Huds. and Ulmus minor Mill.) and four Asian (Ulmus pumila L., Ulmus parvifolia …

Development of microsatellite markers for the European white elm (Ulmus laevis Pall.) and cross‐species amplification within the genus Ulmus

Rachel Whiteley, Sanna Black‐Samuelsson, David E. Clapham

Abstract Ulmus laevis Pall. is a broad‐leaved deciduous tree with a central and eastern European distribution. We describe the development of six polymorphic microsatellite markers for this species. These markers were also tested for utility in U. americana, U. glabra, U. minor …

The effect of nutrient stress on developmental instability in leaves of Acer platanoides (Aceraceae) and Betula pendula (Betulaceae)

Sanna Black‐Samuelsson, Stefan Andersson

Studies of developmental stability can provide insights into the amount of genetic or environmental stress experienced by individuals or populations. In the present study, we used young plants of Acer platanoides (Norway maple) and Betula pendula (silver birch), two distantly related tree …

Genetic Variability in Two Tree Species, Acer platanoides L. and Betula pendula Roth, With Contrasting Life-history Traits

Gösta Eriksson, Sanna Black‐Samuelsson, Martin Jensen, Tor Myking et autres

Genetic variation in adjacent Nordic populations of Acer platanoides L. and Betula pendula Roth was assessed by allozymes and in growth and phenology traits of juvenile trees grown in two field trials, and in growth chambers with free or restricted nutrient access. …

Low isozyme diversity in Nordic and central European populations of Vicia pisiformis and V. dumetorum (Fabaceae)

Sanna Black‐Samuelsson, Martin Lascoux

Vicia pisiformis and V. dumetorum are closely related perennial species occurring in small, disjunct populations throughout Europe. In Sweden, they are classified as “vulnerable” and “care‐demanding”, respectively. They possess low variation in RAPD (Random Amplified Polymorphic DNA) markers but relatively high morphological …
