    Opis:
    The paper presents the results of the research on resistance of a disc coulter in nursery planter type M. Resistance of the working elements of transplanting machines were measured using a device enabling measurement of the force acting against a working element in two directions: horizontally (travel) and vertically. The measurements were performed for four different soil compactness and three moisture variants. Non−linear estimation performed in Statistica 6 software was applied to build a model of the relationship between horizontal and vertical resistance of the working element and soil compactness and moisture.

    Opis:
    The paper presents investigation on influence of root shortening on growth of 2−years−old Norway spruce seedlings after their development in the nursery. Measurements of basic morphological features reveal that strong length reduction increases regeneration of spruce root system. Together with that, slight decrease in height and diameter increment of the main shoot can be observed. Shortening of spruce roots improves significantly the balance between above− and belowground parts of the seedlings as well.

    Opis:
    The aim of this study was to examine the effects of pruning the root system and different doses of nitrogen fertilization on the height and root collar diameter of 2-year-old beech seedlings (Fagus sylvatica L.). This research was conducted in the forest nursery Muchów (Jawor Forest District, regional directorate of State Forests in Wrocław) and two different pruning treatments (no pruning and at 12 cm depth) and nitrogen fertilization doses (25 and 50 kg×ha-1) were applied. Results from an ANOVA showed statistically significant differences between the two pruning treatments (p=0.000) as well as for the interaction of both treatment factors (p=0.019). Root collar diameter correlated with seedling height, both of which were significantly different for the two pruning treatments (p=0.000). No statistically significant impact by the nitrogen fertilization doses on seedling height could be observed (p=0.125). To conclude, we found that it is reasonable to reduce the doses of nitrogen fertilization to half the recommended amount, 25 kg×ha-1, if the root system is not pruned during the second growth year. Seedlings that do receive pruning should be fertilized using the recommended nitrogen doses.

    Opis:
    Pedunculate oak (Quercus robur L.) is among the major managed tree species in Europe. In Poland, oak woodlands cover 6.9% of forest area. Furthermore, the significance of native oaks for Polish forestry is rising because the Polish National Forest Strategy predicts a growth of forest cover from 28.5% to 33% by year 2050 with the primary focus on the increase in contribution of deciduous tree species (from 22% to 33%). Therefore, for establishment of new stands, oak seedlings are grown for 2−3 years in forest nurseries. For optimal growth and development all European oak species are critically dependent on ectomycorrhizal fungi. The objective of this study was to describe the temporal dynamics of ectomycorrhizal community of pedunculate oak seedlings during the first year of growth in bare−root forest nursery. Experiment was conducted in forest nursery Miranowo (western Poland). The species structure of an ectomycorrhizal community was assessed every 10 or 15 days from May till October. Mycorrhizal colonization of tested seedlings changed from 0 to 85% depending of the time of sampling. Based on combination of morphological and molecular techniques, nine ectomycorrhizal fungal taxa were distinguished. The first ectomycorrhizas formed by Scleroderma verrucosum were detected 50 days after acorns sowing. In the next sampling days ectomycorrhizal community was dominated consecutively by Inocybe curvipes and Hebeloma sacchariolens (with maximum of abundance 60.98 and 75.55%, respectively). The obtained results were strongly influenced by the infection with the fungal biotroph Erysiphe alphitoides and resulted in a dramatic reduction in the abundance of living ectomycorrhizas down to 7.5%. Our investigation revealed that ectomycorrhizal fungal community of pedunculate oak seedlings during the first year of growth in bare−root forest nursery is rich in terms of number of species and a temporal changes are very dynamic. Thus we suggest, that in case of pedunculate oak artificial inoculation in general is not necessary for oaks seedlings in nursery practice.

    Opis:
    The goal of this paper was to prove the possibility, and determine the most important hazards of beech planting stock production under the climatic conditions of north−eastern Poland. Considered were time of sowing, soil coverings and mulch type in four operational nurseries of the State Forests over the period of four years. The use of simple nursery technological solutions in bare−root forest nurseries is sufficient for the production of quality beech planting stock, also outside the natural distribution limits of the species. The most crucial natural factors for the production of beech seedlings proved to be: spring frost, damage to seed and seedling by maggots and birds. It was estimated that before the early frost, all seedlings had produced the top bud. The autumn sowing with use of sawdust covering was found to be the most effec− tive technological solution in the sense of planting stock productivity. The spring sowings were less effi− cient because of the necessity to use properly stratified seed, a condition hardly met in the poorly equipped bare−root nurseries. The largest 1/0 seedlings (dry weight per seedling) were those originated after the autumn sowing. The smallest seedlings were grown in plots with coniferous sawdust coverings. Another finding of the study was that the use of above ground covers, allowing 40% daylight intensity had reduced the final dimensions of the one−year old beeches.

    Opis:
    The paper presents research on influence of nursery soil compaction, composed of peat (90%) and perlite (10%), on the growth of seedlings of Pinus sylvestris grown in containers. Polyethylene nursery are containers used for the seedling production. These containers were filled with three different densities of the peat and perlite substrate (0.3, 0.5 and 0.7 g·cm-3). During the experiment, nursery containers were initially placed in a plastic tent for a period of two months, and then for three months further months in an open nursery field. Growth measurements for individual plants were the length of shoots and the root system, root collar diameter, root and shoot dry weight and photosynthetic rate. There was a relationship between the extent of compaction of the soil substrate and all analyzed growth parameters of seedlings. A more compact substrate adversely affected on the number of grown seedlings and their length but positively influenced the dry mass of pine seedlings.

    Opis:
    In forestry management, artificially produced planting material is mainly used for renewal the tree population. Seedlings are cultivated in two systems: in the ground (the bare−root seedlings) and in controlled conditions (container seedlings). The aim of the study was to analyse the microsatellite markers of nuclear and chloroplast DNA, in terms of the number and frequency of rare, private, low frequency and common alleles in the planting material of Scots pine. The rare alleles included alleles occurring with less than 1% in analyzed group of seedlings and low frequency alleles occurred with a frequency of less than 25%. The private alleles were detected only in one group of seedlings. Genetic pools of seedlings from traditional (soil) and container production were compared. Planting material came from nurseries in the Olsztynek (N Poland) and the Oleszyce (S Poland) forest district. With the similar number of observed nDNA and cpDNA alleles in both analyzed locations, a higher number of rare, low frequency and private alleles was found within container seedlings. Most private alleles were a rare allele. Rare and private alleles are supposed to be responsible for adaptation to changing climatic conditions and a stressful environment. It seems reasonable to continue research on the meaning of rare and private alleles under conditions of strong selective pressure.

    Opis:
    The effects of pine and oak forest litter on mycorrhizal status of 2−year−old Pinus sylvestris L. seedlings grown in a bare−root nursery was investigated. The research was carried out in the nursery of Vilnius University Botanical Garden in Lithuania. Ectomycorrhizal communities were assessed by a combination of morphological and molecular techniques. Statistical analysis revealed significant effect of litter treatment on some growth parameters of seedlings: seedling height, needle dry weight and total seedling weight. The survival rate of seedlings was significantly highest for oak litter, intermediate for pine litter, and lowest for control soil. Pine seedlings were colonized by indigenous ecto− and ectendomycorrhizal symbionts. Seven mycorrhizal species (Suillus luteus, S. variegatus, Wilcoxina mikolae, Tuber sp., Tomentella sp., Cenococcum geophilum, Amphinema byssoides) were distinguished on the roots of pine seedlings as well as one ectomycorrhizal symbiont not identified to species level. In total, 6 mycorrhizal types were found in control soil, 5 in pine litter, and 8 in oak litter. Suilloid (S. luteus and S. variegatus) and Wilcoxina mycorrhizae were dominant on tested seedlings, irrespective of litter addition. Seedlings grown in untreated nursery soil were 34% colonized by W. mikolae, while suilloid mycorrhizae were dominant after litter treatment (81% in pine litter and 63% in oak litter). We may conclude that suilloid mycorrhizae are better adapted to the conditions related to litter addition than W. mikolae.

    Opis:
    The production of forest tree species in forest nurseries is performed via two main breeding systems: i) the traditional (conventional) way with the seedlings grown in soil, and ii) plants cultivated in the containers. The aim of the study was to assess the level of genetic variability in the populations of the mother stands and the progeny populations of Scots pine cultured with traditional way (in soil) and in containers in two nurseries in Olsztynek (N Poland) and Oleszyce (S Poland) forest districts. Four polymorphic microsatellite markers (SPAG 7.14, SPAC 11.6, SPAC 12.5 and SsrPt_ctg4363) were used to evaluate the genetic variability of the studied populations. The basic hypothesis assumed that higher gene pool characterizes the seedlings grown in the containers comparing to the seedlings grown in the ground. The results confirmed that. Seedlings from containerized breeding had larger gene pool and were more diverse than plants with conventional breeding, both in Olsztynek and Oleszyce. Our study revealed a significant human impact on shaping the pool of forest genetic resources of Polish forests at the early stage of nursery production and showed the need for a broader study on further stages of cultivation of forests.

    Opis:
    This study examines the influence on growth parameters, in particular the morphological features of the root system, of 1-year-old European beech seedlings cultivated in containers with two different densities. The experiment was conducted in the container nursery in Skierdy (Forest District of Jabłonna) in spring 2011. After 10 months of cultivation in Hiko polyethylene containers, above- and below-ground parts of the seedlings were measured. The measurements of the root system were conducted with a scanner and the WinRHIZO software. No influence due to the seedling density on either shoot height or thickness was observed, but instead the research showed that different seedling densities affected the development of root systems. The mean root thickness and dry mass of the European beech seedlings were significantly higher at the lower density. The influence of seedling density on the development of root mass deserves special attention as it is the most important factor affecting future growth of the seedlings during cultivation. This tendency also suggests that the amount of nutrients allocated to shoot development may be higher in order to improve the efficiency of photosynthesis. At both densities, differences in biomass accumulation affected the root-toshoot ratio. In seedlings cultivated at the lower density, the increased dry root matter of the seedlings resulted in a significant increase in the root-to-shoot ratio. This may cause a potential growth advantage of these seedlings after they are planted and may thus result in a more productive cultivation.

    Opis:
    In this article we analysed the influence of plant-based organic admixtures on the germination process of seeds and the early development of Scots pine Pinus sylvestris L. seedlings. The intensity of dumpin-off diseases within the culture was recorded after applying each of the admixtures. Organic material of nettle Urtica dioica L., softwood litter, hardwood litter and peat were applied to the nursery substrate in two ways, either as an admixture in crushed form or in granulated form. None of the introduced admixtures influenced the germination of seeds or the survival rate of pine seedlings positively. The best results were obtained with a substrate without admixtures used as a control, which is the most common nursery substrate. The worst seed germination rate was observed on the substrate enriched with the organic material from nettles. In pots with granulated organic material from hardwood litter, significantly more seedlings showed signs of post-emergence dermatitis. In all other cases, there was no clear difference between the crushed or granulated admixture in either germination or survival of seedlings. We furthermore demonstrated that the process of granulating plant material leads to an approximately 10-fold increase in the bulk density of the granulated substance, which translates directly into volume reduction.
