Opis:
A comparative analysis was made for different measures of location and variation in height increment of the main stem of the mature black alder from the north−eastern region (N) and two southern regions (S1 and S2) of Poland. Correlation was found between annual height increment and tree age and height, as well as the number of the nodes along the shoot and the length of the internode. It was demonstrated that the trees producing long shoots in a given year would produce long shoots also in the successive years.

Opis:
The studies were based on the empirical material collected in 23 stands located in the territory of the Miłomłyn, Stare Jabłonki and Kudypy forest districts. Height growth model for beech was developed on the basis of measurements of 115 trees growing in the regeneration layer in pine stands. The developed function can be useful, inter alia, for building a 'network of site indices' for shelterwood regeneration. The studies on the height growth rate allow estimating the age at which undergrowth reaches the lower layer of a stand.

Opis:
This study was carried out in north−eastern Poland in 20 Scots pine stands with well−developed lower layer of pedunculate oak. In each stand, 5 highest oak trees were selected. Basing on the stem analysis, a growth model for oak undergrowth in Scots pine stands was elaborated. It can be used for determination the height growth rate in relation to the age and height of oak. Obtained model was compared to the already existing one for oaks growing without canopy [Bruchwald at el. 1996]. Growth rate of undergrowth oaks was significantly delayed in the initial period by 20−30 years.

Opis:
The objectives of this work was to develop a site index models for main forest−forming tree species in Poland based on data from published yield tables. The research material include growth series of birch, European beech, common oak, red oak, European hornbeam, European ash, Norway maple, small−leaved lime, black alder, trembling aspen, locust, Douglas fir, silver fir, European larch, Scots pine, and Norway spruce. Six algebraic difference models were preliminary selected for the construction of site index model. When selecting a potential models an assumption was made, that the index system should be characterized by good fit to the empirical data, polymorphism, variable asymptotes for different sites and equality of the site index and height at a certain base age. To estimate parameters of individual models all possible combinations among height−age pairs for each tree were used. The selection of the best model was based on fit criteria describing: proportion of variance explained, error range and standard deviation of the residuals. Best fitting model was selected basing on the sum of ranks from individual criteria and for each individual tree species a separate model was selected, which fits the best growth series from the yield tables. For 16 out of 19 species, the best fit statistics were demonstrated by the model developed on the base of the function [2]. Developed models may be used both in forestry practice and forestry research in order to estimate site index for analyzed tree species.

Opis:
The paper presents an analysis of height growth phases of silver fir from the Świętokrzyskie Mountains. Basing on bilateral relations between average and current height increments, age of their culmination and duration of main (juvenile and sprouting) phases was determined. Empirical data consisted of 61 sample trees that were subjected to the stem analysis. Juvenile stage of fir height growth lasts 30 years, while sprouting phase is quite long as it lasts 45 years on average. Mean age when analyzed trees reach the culmination of current and average height increment equals 50 and 70 years respectively. Course of height growth of fir resembles this of beech, which can be explained by shade tolerance of these species.

Opis:
Decrease in emission of harmful gases and dusts in industrialised regions of Poland triggered improvement of forest health. Results of research dealing with pine stands in the Olkusz Forest District prove that. It was shown that number of side shoots growing out in the whorl rose up to 4−5. Trees developed height increment over two times higher than the model one and as a result height growth rate increased. Examined stands moved to the higher site index class during last 25 years. The need of further research on growth processes of trees being under anthropogenic influence was emphasised.

Opis:
The aim of the study was to develop a site index model for Scots pine stands in southern Poland describing changes in height growth of stand's upper storey over time. The research material contained the height growth data obtained from an analysis of 189 tree stems. The collected material was used to develop the parameters of six dynamic growth equations which allowed to determine site productivity and predict changes in height growth of stands with age. Statistical criteria for assessing the accuracy of mapping empirical data and biological reasonableness were the basis of selection of the equation that best fits changes in height growth of the examined pine stands with age. The developed model can be used to predict the growth rate and determine the site index for Scots pine stands in southern Poland.

The paper presents the assessment of the adaptive traits (survival rate and height growth) of 5−year−old silver fir one year after planting on conservation plots of the Carpathian Gene Bank (KGB) located in the territory of Wisła, Andrychów, Sucha, Nowy Targ, Krościenko, Nawojowa, Rymanów oraz Bircza forest districts. The conducted studies showed a high (over 90%) survival rate of the tested fir provenances. The growth of the West Carpathian (Beskid Śląski, Beskid Żywiecki, and Beskid Mały) fir provenances was high on the majority of the KGB conservation plots, while the height growth of fir stands from the central part of the Carpathian Mountains (Beskid Wyspowy, Beskid Sądecki, and Beskid Niski) was on an average level. The East Carpathian (Pogórze, Słonne and Bieszczady Mountains) provenances were significantly diversified in terms of the height and did not form a homogenous group.

Opis:
We investigated annual height increment of sessile oak and common hornbeam planted on clear−cut in respect to the distance to the adjacent mature Scots pine stand. The study area was divided into 3 zones (I−III) each of 20 m width. The four analyzed treatments were defined on a basis of a mingling form: W1 – a monoculture of oak (control plot), W2 and W3 – two types of row mixture, W4 – single tree mixture. Two years after planting an annual height increment of both tree species was significantly higher in the zone I (adjacent to the mature pine stand from the SW side) than in two other zones. The same significant differences were also found at the other inventories. Although hornbeam was on average higher than oak, a growth inhibition of oak by hornbeam was not significant. The annual height increment of both species was correlated with the precipitation in June and July.

Opis:
Silver fir is one of the main tree species of mountain and foothill forests in Poland that in optimal conditions forms pure stands with multi−layer structure. The study objective is to present differences in height and diameter growth rates of firs growing in upper stand layers and in the undergrowth. The research was conducted in 12 fir stands located in the Beskid Niski Mts. (southern Poland). In each stand height and diameter at breast height (dbh) were measured for 25 fir trees in order to develop a height curve. The first canopy layer included trees that were higher than ⅔ Hmax established from the height curve of the tree with the largest dbh. Height and diameter were measured on eight trees selected from the first canopy layer. An increment core was extracted at breast height in order to estimate the tree age. From the third canopy layer, which included trees higher than 2 m with dbh below 7 cm, five trees were selected. After cutting those trees, the length of the last ten branch whorls was measured. Five−year ring width measurements starting from the bark towards the pith were done at the stem cross−sections obtained at breast height. The number of rings was counted on remaining stumps. Height growth rate was defined as the height at the base age of 100 years (eq. 1). For the first canopy layer, the height growth rate was on average 31.8 m, while for the undergrowth it was 12.1 m. There was also large difference between diameter growth rate of the first stand canopy layer (55.7 cm) and undergrowth (18.3 cm). Both differences were significant at p=0.05. These discrepancies could result from low amount of light reaching the forest floor. The correlation between height and diameter growth rates and undergrowth tree age was negative in both cases. Long periods of shading result in smaller number of firs reaching the first canopy layer. Assuming that uneven−aged stand structure is optimal for that species, it should be characterized by a spatial variability (mosaic) of various canopy layers including even−aged patches with sparse canopy closure as well as gaps where fir regeneration will be initiated having favorable growth conditions.

The empirical material collected from 12 beech−pine stands located in the territory of the Miłomłyn and Stare Jabłonki Forest Districts was used for the study. The height increment of the beech trees from the second storey of beech−pine stands under study culminated earlier than the height increment of the beech trees from pure, one−storied stands. The beech trees growing in the second storey are also characterised by a shorter juvenile phase.

Opis:
The study compares height growth of pedunculate oak (Quercus robur L.) undergrowth in Scots pine (Pinus sylvestris L.) stands and in open canopy conditions. Material was collected in 20 Scots pine stands with well−developed pedunculate oak undergrowth located in north−eastern Poland, representing the mixed deciduous forest type (Querco roboris−Pinetum). Fraction of oak undergrowth with slow height increment in Scots pine stands amounted 40% and was twice as high as in the open canopy conditions. On average 10 years longer than in the open canopy conditions juvenile phase characterizes the height growth of pedunculate oak undergrowth. A shift of height growth phases of oak undergrowth was recorded. However in most of the stands Scots pine shelter did not cause large delay in the age at which the culmination of current height increment of pedunculate oak is achieved.
