“…The steep climatic cline over latitude in northern Finland and Sweden (Anon. 1991, Alexandersson et al 1991, and the strong natural selection acting on traits important for survival, could explain the population differentiation normally observed , Eriksson 1998). However, because the distance between populations in this study was short (the latitudinal range between the most southerly and the most northerly stands within each group of populations was only 0845?…”

The amount of additive genetic and environmental variance for tree height and field survival, and the genetic relationship between the traits were estimated using data from half-sib progenies of Swedish and Finnish Scots pine (Pinus sylvestris L.) plus-trees, assessed in 18 single-tree plot progeny trials. The progeny trials were established in northern Sweden and comprised 9 Á/13-yrold, Finnish polycross progenies or Swedish open-pollinated progenies. In total across the trials, 71 630 individual trees from 888 families were included in the study. At the overall level, the additive genetic coefficient of variation ranged between 3.1 and 16.3% for height and between 0 and 27.9% for survival, with averages of 9.5% and 14.2%, respectively. Narrow-sense heritabilities were moderate to low, with averages across trials of 0.11 for height and 0.06 for survival. At the within-population level, estimates of genetic correlation between height and survival were mostly large and positive, with an arithmetic mean and standard error across trials of 0.479/0.39.

“…More than 70% of the total variation in height, 14% in diameter and 40% in branching is among populations, whereas no differences are detected in survival. This can be explained by natural selection acting on phenotypes and traits related to biomass production (Eriksson 1998).…”

Plants obtained from seed of 16 Spanish and 6 German provenances of Scots pine (Pinus sylvestris L.) were installed at fi ve trial sites distributed throughout the natural range of the species in Spain. Five years after planting (7 years of age) the experimental material was measured for total height, diameter, number of twigs at the fourth year whorl and survival. The analysis confi rmed that the rate of height growth of the Spanish is lower than that of the German provenances, whereas for the other traits the best Spanish compare favourably with the Germans. Provenance by site interaction was very signifi cant (P < 0.01) for most traits. Attempts to model the interaction of Spanish provenances on height by simultaneous introduction of some climatic and geographic covariates on both factors were not successful but a multiplicative model with one bilinear term was enough to provide a sensible explanation of this interaction. Usually, provenances closest to each trial site were found better adapted than more distant ones but some provenances of close origin presented a different behaviour. Processes of adaptation and selection of these ancient populations could be considered as the main factors to cause this interaction.

“…This could lead to increased risk for water logging since the humidity is high in northern Sweden (Eriksson and Odin 1990). As stated by Eriksson (1998), Scots pine is a species with high phenotypic stability. Trees are able to cope with a great diversity of climatic stresses during their lifetime.…”

Persson, B. 1998. Will climate change affect the optimal choice of Pinus sylvestris provenances? Silva Fennica 32(2): 121-128.Provenance experiments with Pinus sylvestris (L.) were evaluated in Sweden north of latitude 60°N. Survival and yield were determined as functions of temperature sum of the site and latitudinal origin of the provenance. Altitudinal origin was of negligible importance. The effects of latitudinal transfer were influenced by temperature sum at the growing site. At the harshest situated sites southward transfer longer than 3° was optimal for survival and yield, whereas transfer effects in a mild climate were weak. Climatic warming would reduce demands of hardiness. However, moderate differences in productivity are expected between formerly optimal seed sources and the ones adapted to changed climatic conditions. Since mortality usually was low in plantations older than 20 years or higher than 2 m, established stands are expected to be robust against adverse effects of climate change.
