Opis:
Paper studies the influence of climate conditions on radial growth of the endemic Schrenk spruce in the Tien−Shan Mountains in Kyrgyzstan. The research was conducted in four forest regions of Kyrgyzstan, where the analysed species occupies the largest area and along altitudinal gradient. Analysed climate factors included mean monthly temperature and precipitation. Additionally, similarity of growth patterns among study sites were compared with GL ratio and pointer years were determined to characterise situations that resulted in growth extremes. The results showed that high Tien−Shan Mountains create different local conditions in individual forest regions for growth of Schrenk spruce. The most important radial growth controlling factor is precipitation. When analyzing the climate−increment reaction it was found that it is affected by the geographical location, altitude and exposure of the analyzed site. Generally, at lower altitudes the main limiting factor was precipitation, while at higher elevations – temperature. This relationship, however, was not observed in all of the investigated regions. It can be affected by a specific climate of the high Tien−Shan causing different reactions of trees in various places. Because of this, the analyses of the Schrenk spruce radial increments should be performed separately within the existing forest regions.

Opis:
The research objective was to investigate the course of tree−ring width series of silver fir (Abies alba Mill.) growing outside its natural range. Sample material was collected in Wichrowo Forest District in the Olsztyńskie Lakeland region. Dendroclimatological analysis was performed for the period 1952−2000 on the basis of residual chronology and meteorological data from Olsztyn station. It turned out that the thermal conditions at the end of winter influence the tree ring widths the most.

Opis:
The aim of the research was to determine the impact of climatic conditions on the tree−ring width of Swedish whitebeam Sorbus intermedia (Ehrh.) Pers. growing in the urban conditions in Szczecin (NW Poland). The samples were taken from 26 trees growing along Rodziewiczówny, Ejsmonda and Santocka streets (left bank of the Odra river). On the basis of the tree−ring width measurements and cross−dating, two local chronologies (JS1 – Rodziewiczówny and Ejsmonda streets, and JS2 – Santocka street) were developed. Later on we indexed them (double detrending, least squares method and spline function) and subjected to the analysis of correlation and response functions. Growth−climate dependencies in both Swedish whitebeam communities are different. For the JS1 chronology the highest value of the multiple regression coefficient was obtained for air temperature, while for JS2 chronology for insolation and precipitation. For both sequences dependency on climate is similar in August and December of the previous year of vegetation and in January, February, April, June and July of the current year. The observed differences are the result of the impact of various factors related to human activity: traffic volume, soil pollution (mainly heavy metals and salt), damage to roots, trunks and crowns.

Opis:
The main objective of the research was to evaluate the incremental response of Douglas fir and Scots pine subjected to strong environmental stress to variable thermal and precipitation conditions. We also attempted to determine periods of tree−ring width reduction caused by strong anthropopressure associated with the activities of nearby industrial plants, which are burdensome for the environment. The studied forest stands are located in the Kędzierzyn Forest District, in Kotlarnia forestry (50°27'59'N, 18°38'42'E) approximately 8 km away from the nitrogen production plants. We used standard methodology applied in the dendrochronological studies with the support of the TSAP−Win, Cofecha, Arstan and Quercus 06.01 softwares. We found that Douglas fir and Scots pine stands growing in the permanently damaged zone due to the adverse effects of industry responded to meteorological conditions in a manner typical of the species. In the study of the relationship between weather and growth, thermal and precipitation conditions were more important in the current year than in the year preceding the increment. A similar distribution of reductions and periods of partial regeneration in both species were also observed. In the same multi−annual period of 1961−1991 deeper reductions of annual increments were observed in Douglas fir (>70%) than in Scots pine (in the range of 50−70%). Conditions, in which trees grew in the Kędzierzyn Forest District, contributed to the decrease in annual increments of both Douglas fir and Scots pine, while the previous species turned out to be a more sensitive one, which had been indicated by other researchers ealier.
