Long-term growth performance and productivity of Scots pine (Pinus sylvestris L.) populations
Acta Societatis Botanicorum Poloniae
The phenotypic differentiation of 16 provenances of Scots pine originating from a wide variety of habitats that range from lowland to southern highland locations in Poland was assessed during 47 years of their growth and development in the Carpathian Mountains. The traits, including height, diameter at breast height, stem straightness, and crown width, were used to evaluate the differentiation of the provenances in their juvenile period and at maturity and were examined for patterns of local adaptation. The populations from northern Poland were characterized by the best growth and productivity, whereas provenances from central Poland had the best stem quality. There were some changes in growth between provenances observed during the experiment, but the stand volume (m<sup>3</sup>/ha) in juvenile trees was closely correlated with that in mature trees (<em>r</em> = 0.979). There was a positive relationship between the productivity and the environmental conditio...
The influence of temperature on the height increment of Scots pine (Pinus sylvestis L.)
Acta Scientiarum Polonorum Silvarum Colendarum Ratio et Industria Lignaria
The annual height increment of Scots pine exerts a direct influence on the determination accuracy of the tree and the stand volume increment. It is considered as a major dendrometric characteristic. However, the growth of trees depends on the meteorological conditions in the year that preceded increments, as well as in the given incremental year. In this study the relationship between annual increments, and temperature was examined. For this purpose correlation coefficients between monthly temperature and mean annual height increments were designated. Next, the forward stepwise regression procedure was used. For this purpose the SAS software package was applied. On the basis of the presented research it was found that the Scots pine increments are greater when summer months, both of the pervious year and of the given vegetation season, are cooler and when March is warmer.
Climate-tree-growth relationships of Scots pine stands (Pinus sylvestris L.) exposed to soil dryness
Trees, 1998
Dendroclimatological techniques were used to assess the impact of climatic factors on radial tree growth (total ring-width and latewood-width) of stunted Scots pine trees (Pinus sylvestris L.) exposed to soil dryness and nutrient deficiency on a dolomite substrate. The response of eight scattered populations representing various habitats, yet influenced by the same regional climate was investigated. Total ring-width and latewood-width were dated, standardized and several chronology statistics, which estimate the chronology signal strength and the potential climate signal in the series, were determined. Dendroclimatic analysis comprised evaluation of event/pointer years as well as response function ele-

The results of long-term dendrochronological investigation of Scots pine (Pinus sylvestris L.) growth and condition in the impact zone of one of the biggest air pollution sources in Lithuania as cement plant Akmenës Cementas are presented. Conifers are especially sensitive to environmental pollution. As an anatomical indicator of anatomical indicator of tree vitality, annual radial increment of trees was examined. The dynamics of the annual radial increment is influenced by the main climatic parameters (air temperature and amount of precipitation) as well as environmental pollution. The main attention was concentrated to assessment of the complex impact of climatic factors and industrial pollution on the radial increment of pine stands growing at different distances from the plant. Results of investigation and climate response models have shown that closest pine stands have suffered the strongest pollution impact, while the furthest pine stands were affected only by natural factors.
Effects of age and site quality on the distribution of biomass in Scots pine ( Pinus sylvestris L.)
Trees-structure and Function, 1996
The distribution of the above-ground and below-ground biomass of Scots pine in southern Finland were investigated in trees of different ages (18–212 years) from two types of growth site. Secondly, some structural regularities were tested for their independence of age and growth site. Trees were sampled from dominant trees which could be expected to have a comparable position in stands

OBERHUBER W. & KOFLER W. 2000. Effects of site related environmental stresses on radial growth of Scots pine stands Pinus sylvestris (L.).-Phyton (Horn, Austria) 40 (4): (149)-(152). Dendrochronological and multivariate techniques were used to assess the influence of climate and site-specific factors on radial growth (tree ring-width) of stunted Scots pine trees Pinus sylvestris (L.). Tree growth within the study area (750 m a.s.l.) is strikingly restricted due to the inherent low nutrient content and retarded soil development of dolomite parent material and low water holding capacity of the predominantly shallow, stony soils. The climate-tree-growth relationship of eight scattered populations belonging to the same phytosociological community, a Spring Heath-Pine wood (Erico-Pinetum typicum), was investigated. Arrangement of sites was in relation to a "moisture gradient" defined in terms of a physiographic series from hollows to open southfacing slopes, i.e. from slightly moist to the most xeric sites. Though the overall climate response at the various habitats is similar, principal component analysis resulted in clustering of habitats according to topographic features (slope magnitude, slope aspect, soil depth, vegetation cover). This study shows that at the limit of tree growth, small scale variation of edaphic conditions exert a major influence on susceptibility of trees to environmental stresses.

Changes in the structure and development of managed Scots pine ( L.) stands with respect to changing environmental conditions were set for the period 1979â2015. The study was conducted in conditions of natural pinewoods and pine-oak sites on five permanent research plots (0.25 ha) in Eastern Bohemia, Czech Republic (CR). Studied forest stands showed positive development of stand structural characteristics related to their diversity, number of regeneration individuals and growth characteristics. The standing volume of regularly distributed tree layer in 2015 was in the range of 320â434 m ha, which indicates an increase by 5.9â20.0% over 10 years. Correlation between pine radial increment and the amount of precipitation was generally the strongest one. Positive statistically significant correlation between diameter increment and temperature was demonstrated only for the average March temperature of the current year. Within the CR, study site can be characterised as a medium poll...
The effect of precipitation on the height increments of eight age classes Scots pine
2013
Annual increments of the height of Scots pine are the main dendrometric characteristic because the annual radial increments can be clearly determined in this way. The meteorological conditions occurring at the time of budding, as well as the growth of trees, are important to the size of the increments. In this study, the dependence of annual increments on precipitation were examined. In order to determine this dependence, correlation coefficients were designated, in addition a forward stepwise regression analysis was used. On the basis of the conducted analysis it can be concluded that the Scots pine has greater increments when precipitation is more abundant in the july of the year preceding the vegetation season. moreover, the Scots pine has longer increments when the vegetation season is drier.
