W pracy stwierdzono, że jedynie drzewostany Beskidu Żywieckiego (masyw Pilsko-Romanka) do wysokości około 900 m n.p.m. rozwijają się w warunkach, które na podstawie tendencji przyrostowych uznać można za niezakłócone. Największy spadek przyrostu grubości i zahamowanie jego dynamiki w okresie 1977-1986 w porównaniu z 10-leciem 1967-1976 stwierdzono w obrębie Szczyrk (masyw Skrzyczne), szczególnie w partiach przygrzbietowych (ok. 1100 m n.p.m.). Wykazano również, że stopień zahamowania dynamiki przyrostu grubości istotnie zależy od wysokości położenia drzewostanu n.p.m. Nie zależy natomiast od wystawy ani też liczby drzew w drzewostanie w obrębie danej wysokości n.p.m.

The study was conducted on the material collected in 62 older spruce stands (tab. 1) of Silesian Beskid-Skrzyczne massif, and Żywiec Beskid Pilsko-Romanka massif (fig. 1). The dynamics of diameter increment was determined using the dynamics index for the period 1967-1976 (W1) and 1977-1986 (W2). The change in dynamics during these periods was characterized by the index (Wx), while the drop in dynamics (S x) of stands of Skrzyczne massif was expressed in the percentage of (he dynamics of control stands (Pilsko-Romanka massif). The study showed that: the stands of south eastern slopes (S-E) were characterized by higher diameter increment during the periods investigated (tab. 1), as well as by greater dynamics (tab. 2) as compared with stands growing on north western slopes (N -W); the magnitude of index (Wx) significantly depended on the elevation of stand above sea level, while it was independent from stand's age, exposure, and the number of trees per unit area at a given altitude above sea level (tab. 3); there was a distinct slow-down in the diameter increment and its dynamics in stands of Skrzyczne and Pilsko-Romanka at the elevation of 1000 m above sea level (tab. 4, fig. 2); The slow-down in the dynamics of diameter increment of stands of Silesian Beskid (Skrzyczne massif) was by about 20% higher than that of stands of Żywiec Beskid (Pilsko-Romanka massif), and it was true for all elevations (tab. 2).

W pracy wykazano, że po prawie 20-letnim okresie zmniejszenia się przyrostu bieżącego promienia na pierśnicy, w lalach 198 L 90 nastąpił wzrost jego wartości (regeneracja przyrostu) zasadniczo na przeważającej części objętego badaniami obszaru. Żywotne drzewostany, zapewniające normalny przyrost zbliżony do tablicowego, występują jeszcze głównie w południowo-wschodniej części kraju (od Beskidu Sądeckiego po Bieszczady) oraz częściowo w Górach Świętokrzyskich i na Roztoczu.

The aim of studies carried out in fir stands (Table 1) in 1992-1993 was lo determine the pattern of changes in the width of annual rings of firs in 1941-1980 and 1980-1990 (figs 1-9) and to estimate changes of their biumorpholugical trails occurring in the period 1983(85)-1992(93). On each of 23 study areas 15 firs, chiefly representing the second Kraft's class were selected and twice drilled with a Pressler increment borer. The tree height, diameter at breast height, and the crown length were measured and the trees were classified with respect to the type of the top, degree of crown distortion, and vitality. Mean values of 10-year current increments of the radius from two drillings were used in calculating growth indices (formulae 1-5) [5, 6] for each drilled tree, the indices describing the given stand being computed on this basis. Empirical values of increment indices were compared with theoretical (tabular) indices which were regarded as minimum values characterizing the normal condition of stand vitality. The following values were taken into consideration: Index II ≥ 0.70, indices I, IV, and V ≥ 0.79, the critical value of index VII being 0.73 for younger and 0.66 for older stands. In stands of age classes III and IV analysis of 10-year averages of (he current increment in radius showed that after its very distinct decrease in most study areas investigated in 1961-1970 and 1971-1981, an increase in the increment value was recorded in a half of these plots during the decade 1981-1990. Analogical analysis carried out in stands of older age classes also showed a changed tendency in the years 1981-1990 as expressed by an increased 10-year current increment in 12 out of 15 stands (Table 2). Analysis of vitality indices showed that this trait of the investigated stands did not change in most study plots. The poorest vitality characterized the stands in Sudeten Mts (Bystrzyca Kłodzka and Międzylesie), Żywiec Beskid Mts (Jeleśnia), Silesian Beskid Mts (Ustroń), Świętokrzyskie Mts (Zagnańsk III), and Andrychów. Of the investigated forests the most vital stands estimated on the basis of their morphological traits, were found in the Carpathian Plateau (Brzozów I, Krasiczyn), Bieszczady Mts (Baligród I and M), in Roztocze region (Roztocze National Park and Zwierzyniec), and also in Kraków-Częstochowa Upland (Olkusz) (Table 3). Analysis of increment indices (II and Vit) and fir vitality as a result of biomorphological tree traits shows that stands with relatively high increase of increment are situated in southeastern part of Poland (Bieszczady Mts, Beskid Niski Mts, Beskid Sądecki Mts and Carpathian Plateau) and central and eastern part of Małopolska Region (partially Świętokrzyskie Mts and Roztocze).

On the basis of data from 46 growth and yield tables it was shown that in even-aged monospecific tree stands the product of the maximal current annual height measurement and the age of height growth culmination is species-specific and in analysed samples was not related to the site quality expressed by the site class. It was also shown that the above mentioned relationships can occur also in tree stand of a more complex structure than the analysed ones.

The aim of control studies carried out in 23 fir stands [3] in 1992-1993 was to determine dependences between the vitality and biomorphological trails of tree crowns (relative crown length, type of the tree top, and distortion of the crown) and the current radius increase in diameter at breast height from the years 1981-1990. The determinations also concerned traits characterizing normally growing firs in two age classes of the stands: younger (age classes III and IV) and older (age classes V and higher ones). The dependences mentioned above were determined using equations of linear regression and coefficients of linear correlation compared with critical values for the 'significance level оf 0.05 (0.1 for exceptional cases). The equations were also used as a basis in computing vitality indices and morphological traits of trees showing growth regeneration in the investigated period 1981 -1990 as compared with the years 1951-1960. Additionally, for younger and older stands separately the most frequently occurring traits оf trees characterized by the values of index VII (the ratio of increment from 1981-1990 to that from 1951-1960) exceeding the critical value. Significant dependences upon the current growth from 1980-1990 were assessed for all the investigated trails and in (he two groups of stands (Table 1). No dependence upon index VII was shown only for the crown distortion both in younger and older stands. The remaining traits are significantly correlated (Table 3) The particularly high values of correlation coefficients were found for the relative length of the crown, the type of the top, and the vitality (Tables 1, 3). On the basis of the regression equations the following traits were calculated for fir trees which manifested the regeneration of growth: relative crown length, a minimum of 42% for younger and 31% for older stands, the type of tree top 1-2/3 and 1-3/4, respectively, and the vitality 1-2/3-3 and 1-3/4. The normally growing trees were most frequently characterized by the following indices (for younger and older stands, respectively): relative crown length 40-50% and 40-45%, the type of tree top 1-2 and 3, the degree of crown distortion 20 and 20-30%. the vitality 2 and 3-3/4.

The paper describes evaluation of spruce radial growth variability, based on of synchronized individual increment sequences (dendroscales). The empirical material were increment samples from 215 trees, growing on ten research plots in the Silesian and Żywiec Beskids. For each plot in each year there was calculated the raw average chronology, indexed chronology and the coefficient of variation for incremental indexes. In addition, an analysis of the occurrence of pointer years was performed. The observed medium-term changes of the analyzed incremental indices lead to conclusion that in the second half of the twentieth century, a certain external factor influenced the growth of tested spruces. Both the obtained results and the existing studies provide a basis for an assumption that this factor was mainly air pollution.

The width of the annual cambial rings of the sprucesgrowing in a humid habitat in the Valley of Górna Wisla (The Forest District of Pierściec) was influenced by the thermic and pluvial conditions: a) considerably significant influence on the width of the annual-rings had the thermology of the winter (December-March) which preceeded the vegetative period (March-May); b) also, the year's rainfall, particularly that during the turn of spring (June-July) had an important role in the formation of the tree-rings. The tree-ring reaction uf the spruces from Pierściec on the с li mato logical influences was slightly different from that stated in the spruce population from Beskid Śląski [5]. (The Forest District of Bukowiec, 650 750 above the sea level, about 25 km from Pierściec). The spruce from Beskid Sląski formed smaller annual-rings during the years of high summer temperatures (June-September), on the other hand, wide rings were formed during the humid summer, especially after the heavy rainfalls during the vegetative period (April-August).

W pracy wykazano, że dynamika przyrostu grubości zależy od wieku drzewostanu, a nie od liczby drzew w drzewostanie ani też warunków siedliskowych. Przed uruchomieniem elektrociepłowni drzewostany z rejonu Połańca charakteryzowały się dynamiką podobną do kontrolnych. W pierwszym 10-leciu jej działalności nastąpiło wyraźne zahamowanie ich przyrostu grubości, a oszacowane straty wynoszą średnio 21,1%.

The purpose оf this study was to determine the diameter increment dynamics of Scotch pine stund к growing in the theoretical range of the industrial emissions of the Połaniec thermal-electric power station. The study material was colluded in 45 forest stands (tab. 1), while the comparative material originated from the Wyszków forest management unit, i.e. the area free of the industrial pollution. The diameter increment dynamics was expressed by the quotient of the diameter increment in a given 10-year period to d.b.h without bark at the beginning of the period. The dynamics index was calculated for the period 1967-1976 (W1) and 1977-1986 (W2). It was concluded that value of this index depends on stand's age, and not on the number оf trees in the stand or site conditions (tab. 2, fig. I, 2 and 3), During 1967-1976 the diameter increment dynamics in stands near the Połaniec thermal-electric power station was similar to that observed in the control stands (fig, 4a), A distinct slowing down of the diameter growth was observed during the first decade of the power station's activity (fig. 4b). Estimated losses in the diameter increment dynamics amounting to 21,1% on the average (fig. 4e) indicate a negative effect of the industrial pollution caused by the Połaniec station on the diameter increment of forest stands growing within its reach.

Thermal conditions of early spring (March-April) were the main factor that determined the sizes of wood increments of spruces in the subalpine forest zone of the Beskid Żywiecki Mountains. Tree-ring widths of trees growing above the altitude of 800 meters were also influenced by the temperatures of June-August. Diverse sensitivity of the spruces to summer thermal conditions allowed us to separate two dendroclimatologically different zones in the subalpine forest zone: an upper one, above the 800 meters izohypse, and a lower one, below this altitude.

Increment tendencies of the investigated spruce and larch stands were estimated in the work. The effect of selected morphological traits of the crown, vitality, trunk quality, and weight of the root system on increases in the radius at diameter breast high of spruce and larch was determined. In spruce stands 15 permenent sample plots were established and dependences occuring in these stands were analysed in older age class IV and higher ones and younger (age class III) objects. In larch stands 7 study areas were located. The obtained results show that in younger spruce stands the increment is charakterized by a decreasing tendency. Older spruce trees efficiently resist the tendency to increment decreases he I o w the tabular values.

The purpose of this study was to determine a trend of the tree diameter increment, its changes, and losses in the diameter increment in stands developing within a reach of industrial immissions. Investigations were carried out in 90-year-old Scotch pine stands situated in different danger zones of three industrial regions: (the Tarnobrzeg Sulphur Basin (TZS). the Legnica-Głogów Copper District (LGOM), and zinc and lead smelting works in Miasteczko Śląskie (MSL). A method of converion of absolute increment values into coefficients I (formula 2) was utilized. The actual increment for individual calendar years is shown in Fig. 1, and after conversion into coefficients in Fig. 2. Changes in trend were determined using coefficient Is calculated by formula 3, and increment losses using coefficients I1 and I2 calculated by formulae 4 and 5 (Table 1, Figs. 2, 3). It was concluded that after 1967 in stands situated within a reach оf industrial immissions the changes look place in tree diameter increment trend. These changes have a similar character in all industrial regions, and their negative direction increases with increase of industrial hazard from zone 0 to zone III. The estimated losses in the tree diameter increment during the last 25 years (1968-1992) were 21.1% to 26.7% and in some shorter periods reached as much as 36.7%.

The purpose of this study was to characterize the current annual increment of d.b.h. radius of trees in 40, 60 and 90-year-old Scotch pine stands situated in different danger zones of three industrial regions: the Tarnobrzeg Sulphur Basin (TZS), the Legnica-Głogów Copper District (LGOM), and zinc and lead smelting works in Miasteczko Śląskie (MŚL). The study material in from of icrement borer cores taken from every fourth tree was collected in 62 experimental sites (Table 1). Mean increment of d.b.h. radius was calculated for each urea for two 25-year increment periods. First (x1) comprised the period 1968-1992, i.e. the period when stands were developing under the effect of industrial immisions, and second (x2) for the period 1943-1967, i.e. before the occurrence of harmfull factor (Table 2). The dynamics of diameter increment drop was determined using drop coefficient (W) according to formula 3 (Table 2). The course of current diameter increment (Figs. 1-3) was balanced using six different formulae (I-IV). One formula was selected (formula II) and used to determine a model course of diameter increment (Table 3, Figs. 4, 5). The results obtained permitted to draw the following conclusions: 1. Current annual increment of d.b.h, radius during the last 25 years (x1) depended on age of a stand and amounted to 1.11 -1.52 mm in 40-year-old stands. 0.99- 1.15 mm in stands 60-years-old, and 0.78-0.81 in stands 90 years of age. 2. Magnitude of increment and its drop depended on stand age and danger zone, i.e. the increment decreases, and the drop increases as the threat to forest stand increases. 3. Course of the current annual increment of d.b.h, radius after its culmination is represented by function with formula у = a + b/w (formula II), and the model curves drafted on its basis may serve in evaluation of increment course in individual industrial danger zones.

The paper discusses the results of the research concerning the climatic conditions of the tree-ring growth of the beech, fir, spruce, larch and pine that constituted the stand in the Beskid Śląski, Wisła forest inspectorate, section 146b in the forest-district of Bukowiec. The stand, approximately 145 years old, grew at the altitude of 650—700 m above the sea level, on a steep slope, on the acid, brown soil of a strongly skeletal structure. On the basis of the dendrochronological analysis a strong relation between the tree-ring radial growth and the totals of atmospheric precipitation in the year preceding the growth and in the year of its appearance was found in all the species examined. This strong relationship between the cambium activity and the amount of precipitation (despite the favourable pluvial conditions of the region) was probably caused by the small ability of retaining and collecting water by the strongly skeletal soil present on the steep, mountain slope. Furthermore, it was found, that the tree-ring sire of such species as beech, fir and pine was negatively influenced by frosty winters. The high temperature during the growing season stimulated cambium activity of beech and fir, whereas it negatively affected the size of the tree-rings formed in spruce.
