Opis:
The paper presents laboratory test results of the effect of water extracts from the aboveground parts of herbaceous plants on seed germination and germinant growth of Scots pine (Pinus sylvestris L.). Under Polish site conditions species considered suitable for plantations as ground cover plants were selected for the experiment. The use of cover crops may be an alternative for the manual, mechanical and chemical methods of protecting forest plantation against weeds. The results of the research concerning allelopathic effect of the ground cover plants point to the uselessness of their application in areas designated for seeding or natural seeding of Scots pine during green mass decomposition of cultivated plants.

Opis:
Spontaneous regeneration in the hurricane−disturbed stand in the Pisz Forest District (N Poland) was registered in the years 2007−2008 and 2011−2012. Breast height diameter and crown size were measured on 10×10 m plots. The analysis also included the soil respiration rate, the decomposition rate of organic matter, soil pH, leaf area index (LAI), content of Mg, Ca, C, N and P in soil, and vegetation coverage of the forest floor. The natural regeneration was dominated by birch, followed by pine, which recolonized the disturbed stand in smaller extend, possibly because of the thick cover of organic material hindering germination and making it difficult for pine sprouts to reach the mineral soil. Spontaneous regeneration of the stand was most severely inhibited by Deschampsia flexuosa, whose growth over the entire surface was linked to the capture of excess released nitrogen resulting from the decomposition of organic matter. Mosses and lingonberry did not delay the spontaneous appearance of seedlings. The development of the natural regeneration suggests the possibility that an uneven−aged stand will emerge.

Opis:
Eight isozyme gene loci were used to compare genetic structure and variation of parental and offspring populations of Scots pine (Pinus sylvestris L.) in the seed tree stand located in the Woziwoda Forest District of the Tuchola Forest. Although, the estimated parameters indicate small reduction of heterozygosity in offspring populations, the stand may be considered as a valuable seed source for reforestation.

Population's ability to pass genetic information to the progeny generation can be expressed through the effective population size. The true number of individuals in a population plays a significant role in ecological sciences however when considering population genetics effective population size is taken into account in the first place. The presented paper is an analysis of the variation in effective number of clones in Scots pine seed orchards in Poland for three organisation levels: plantations, Regional Directorates of State Forests (RDLPs) and jointly for the country. Thus, the effective number of clones calculated for RDLPs and the country informs about the full potential of genetic variation within a given level.

Opis:
Paper presents analysis of differences in conventional wood density of Scots pine measured at breast height regarding the geographical location of stands, forest habitat type, stand age and associated parameters such as density in the mid−length of the stem, density in the upper end of the stem and diameter at breast height. To investigate the impact of these factors, an analysis of covariance was used in accordance with two models specifically developed for this purpose. We found dependence of conventional wood density on the type of forest habitat and geographical location of the stand. The highest density was detected in dry coniferous forests, while the smallest in fresh mixed coniferous forests. Scots pine wood from Zielona Góra Forest (western Poland) characterised with the highest density, while from the Knyszyn Primeval Forest (eastern Poland)− with the lowest.

Opis:
The experiment area was located in the territory of the Góra Śląska Forest District (western Poland). The plantation was established in 2000 on former agricultural land. One− and two−year−old Scots pine seedlings were used in the experiment. The planting methods applied included wedge planting with a traditional forest and Huff’s dibblers, a garden planting spade, a ‘Junack’ spade and three types of planting machines. Measurements were taken in 2000, 2001, 2002, 2003 and 2008. Differences in the growth characteristics of plantations and young stands are not only statistically significant, but also of great practical importance. The operation of planting machines was significantly more effective, which was manifested in a higher survival rate, height growth, and larger breast height diameters and total basal area. Huff’s dibbler fell short of expectations as a hand tool.

Deformation of the root systems was detected in the pines growing on excessively compacted soils of a dump and in the pines growing in a sand mine pit with a shallow groundwater table. In both cases, the ratio of root biomass to aboveground biomass was considered too low, which might indicate a risk to stand nutrition and stability.

Opis:
The aim of the study was to compare the growth of plantations established with manual and mechanical methods using planting material of various age. The experiment was established in 2000, in the Góra Śląska Forest District (W Poland) on a former farmland. One− and two−years−old Scots pine seedlings were used. Applied planting methods included: conventional planting bar, German Huff's dibble, trowel, Junack spade and three types of planting machines. The complete random block design with five replications was adopted. For the requirements of machine operation, unit plots were elongated rectangles with the longer side of 100 m and the shorter side of 4.5 m. Each plot consisted of three trenches. Spacing between seedlings in the trench was selected to ensure 10,000 seedlings/ha density. Measurements were carried out in 2000, 2001, 2002, 2003, 2008 and 2015. In the first five dates all heights were measured and seedling survival rates were established based on the number of measurements. In 2008 and 2015 all diameters at breast height were measured. In 2015 height of sample trees was recorded, while the height of the other trees was calculated according to the Prodan model h=d2/(a+bd+cd2)+1.3. Based on the measured diameters at breast height and established heights, basal area at the breast height and total tree volume were calculated for each plot. Survival rate is the primary parameter in the evaluation of planting methods, as it most effectively differentiates treatments. Stand height showed no significant diversification with regard to the treatments. For mean diameters at breast height the only differences were found between two−year old and one−year old seedlings, irrespective of the planting method. Despite the lack of differences in growth, effects of various planting methods and different planting material remain and as a result of high class timber already found in the stand these effects have become economically important. The decision on the selection of a particular planting material type and planting method has extensive economic consequences, as it affects productivity of grown stands at least at the first thinning operations. Planting machines are good tools in the establishment of forest cultures and the quality of their work exceeds that of manual operations.

Opis:
We looked at the patterns of differentiation at a set of phenotypic traits of Scots pine populations derived from different environmental conditions of the species distribution range in Poland. The growth traits were tested over 47 years at the provenance trial experiment in the Carpathians. The phenotypic differentiation of the populations was compared to diversity estimates at a set of ten nuclear microsatellite markers. Scots pine populations were highly differentiated concerning diameter at breast high, stand volume, stem straightness and crown width according to the prove− nance and climatic zones. At the same time a low genetic diversity for microsatellite markers and no evidence of population structure was found among proveniences. Local populations from the Carpathian Mountains had lower genetic variation and weaker growth compared to lowland provenances. Among the tested populations Scots pine from lowlands were characterized by the great growth potential and good adaptation to the severe climate of the Carpathians. Populations that showed high quantitative traits differentiation were genetically homogenous at the neutral loci. The results indicate that there are some regions in the genome under selection that drive species adaptive variation.

Opis:
A prerequisite for effective forest management is a detailed economic analysis of given management determinants. In the forest district’s expenditures, next to the wood harvesting and skidding, the cost of silvicultural activities constitute a considerable share. The choice of forest management methods, including those for forest regeneration has a significant effect on the costs incurred for silvicultural activities as well as on the quality of emerging new generation. The aim of the study was to assess the economic effectiveness of Scots pine stand management using natural and artificial regeneration. The research determined the size and structure of expenditures incurred for the establishment and maintenance of crops. We also carried out the analysis and assessment of the effects of the selected regeneration method on forest management economic efficiency. The economic analysis included the comparison of the costs of establishment and maintenance of stands with artificially regenerated Scots pine trees with the costs of analogous activities carried out within the research plots with Scots pine from self−seeding. The studies were carried out on 4 types of forest sites, i.e.: fresh coniferous, fresh mixed coniferous, wet mixed coniferous and fresh mixed deciduous. The analyses were carried out using the cash flow method – the stream of expenditure incurred for stand management. The total costs of artificial stand regeneration and maintenance were on average higher by 1,443.24 PLN/ha of plantation as compared to naturally regenerated stands. Lower costs of tending and corrections performed in artificially regenerated Scots pine stands did not compensate for high expenditure incurred on regeneration activities, and as a result the total cost amounted to an average of 5,002.94 PLN/ha, whereas in the case of natural regeneration the total cost was 3,559.70 PLN/ha. In the analysed methods, the site conditions were of great importance to the amount of expenditures incurred for stand regeneration and maintenance. The economic viability of forest natural regeneration was confirmed for fresh coniferous, fresh mixed coniferous and wet mixed coniferous habitat types. In fresh mixed deciduous site, high costs of tending treatments and corrections had a major effect on the low economic result of the natural method of forest regeneration. The presented results on the effectiveness of management of Scots pine stands or those with the predominance of Scots pine using natural and artificial regeneration can be an important factor in taking appropriate silvicultural decisions, based on the assessment and knowledge of determinants affecting profitability of undertakings.

The planting was performed in April 1994, using 2/0 pine and alder seedlings in a different proportion: 0%, 25%, 50% and 100%. The seedlings were arranged in six complete blocks. A mixture planting of single trees and row of trees was applied. The soil was prepared in furrows without subsoiling (deep tilling). Preliminary results indicate the beneficial effect of alder on the size of breast height diameters of pine already with a 25% participation of this species. No effect on pine height was observed.

Opis:
The aim of the study was to determine the rate of mineralization of needles in a pine stand in relation to site and to microbiological conditions occurring on dune slopes of contrasting aspects. The research was conducted in the old−growth pine forest overgrowing a latitudinally located dune in the Bydgoska Forest (N Poland). On contrasting dune slopes (northern and southern) rate of mineralization of pine needles was investigated in the 2−years experiment (2012−2014) with the litterbag method. Besides, following investigations were conducted in the middle part of both slopes: 1. dynamics of soil moisture and soil temperature were measured at a depth of 3 cm for 18 days during the 2013 growing season (interval of 2 weeks was applied) and 2. populations of bacteria and fungi were determined for all subhorizons of organic soil horizon (Ol, Of, Oh) as well as for a mineral horizon (AEs) of both soils. Weight loss of needles was found to be higher on northern than on a southern slope what was consequently stated for all 4 terms of taking measurements (6, 12, 18 and 24 months after placement of litterbags). The discrepancy has increased with time and after 2 years it equaled 14.7% when the loss was 61.1% for northern and 46.4% for a southern slope. It could be surprising that such differences were found in spite a sunny slope was characterized by stated in a study higher soil temperature. It should have a stimulating effect on mineralization of organic material; however a soil located on a southern slope was also found as much drier. Thus, the periodic deficiency of soil moisture was indicated as a limiting factor for occurrence of both bacteria and fungi on a southern slope due to the numbers of both groups of microorganisms were much lower on the slope than on a northern aspect. Conditioned by more favourable site parameters, higher number of microbial population occurring on a shadow slope could explain higher rate of mineralization of needles stated for the slope aspect. The moisture factor can be of especially high significance for microbial occurrence and activity and thus for litter decomposition just in dry inland dune ecosystems. It was concluded that in relatively monotonous pine forests overgrowing dry and poor in nutrients soils of inland dunes the slope aspect is an agent significantly differentiating both site and soil microbial conditions.

Opis:
Investigations were conducted on 48 Scots pines coming from 16 natural sites in northern Poland. This study was an attempt to analyse relationships between crown parameters of model trees and the stem conduction area in terms of site conditions, age and social diversification of the stand. Analyses showed that there is a strong dependency between crown volume and the volume and area of the xylem (sapwood) responsible for the conduction of water with minerals. Indexes of crown transpiration productivity analysed in the study seem to reflect reliably relations found in the forest phytocenoses and are confirmed in physiological dependencies between the transpiration apparatus, the vascular zone and tree height determined by the occupied social class in the forest community. It may be assumed that sapwood area (physiologically active) is characterised by the variable hydraulic conductivity, probably being the function of age and specific individual characters. In order to maintain the flow of transpiration, optimal for growth conditions, a tree as every living organism exhibits a certain adaptation ability, which makes it possible to meet the above conditions and cope with competition in the community.

Effects of pre−planting soil preparation on the clear−cut on the community structure of soil fungi and bacteria, their possible biological activity towards Armillaria and Heterobasidion, and mortality of Scots pine trees were studied in 40−year−old Scots pine plantation in Międzychód Forest District (W Poland). Pre−planting soil preparation included: (i) deep ploughing, (ii) shallow furrowing, (iii) making holes for planting, and (iv) shallow turning of the topsoil. The soil−dilution method was used for detection of fungi and bacteria in soil. Morphotyping was used for identification of fungi. Phenotypic traits and biochemical properties were used for identification of bacteria. Molecular method, MID−66 or BIOLOG® systems were additionally applied for identification of the most common bacteria. Deep furrowing, making holes for planting or shallow turning of the topsoil before planting increased abundance of fungi and bacteria in soil 40 years after treatment. Increased abundance of fungi and bacteria was associated with increased presence of taxa considered as antagonistic to Armillaria and Heterobasidion. The highest mortality of Scots pines was observed on sites with deep ploughing or shallow furrowing before planting, while the lowest mortality was found on sites with making holes for planting or shallow turning of the topsoil. The majority of dead trees were infected by H. annosum. Moderate intervention into the soil habitat on the clear−cut site before planting of Scots pine seedlings seems to create the habitat beneficial for the future growth of trees.

Opis:
The aim of this study was to assess the impact of the biosocial position occupied by the tree on the amount and structure of the biomass produced. The empirical material was measurements of biomass for 63 pines (21 for each of the I, II, and III Kraft classes). The total aboveground biomass of the trees was calculated as sum of following fractions: stem wood, stem bark, living branches, dead branches, shoots, needles and cones. It has been found that with a decrease of biosocial position of tree the share of a stem increases while share of branches in the overall biomass of the tree decreases. On the other hand biosocial position does not affect significantly the share of needles, dead branches and cones.
