Opis:: Ericales is an ancient eudicot order encompassing numerous species of economic and ornamental values. Despite several phylogenomic studies, the evolutionary relationship among certain families of this group remains uncertain. The present study assessed a multilocus species tree of Ericales based on 107 chloroplast genomes. The plastome derived microsatellite motifs were also simultaneously explored to check their dynamicity in corroboration of species phylogeny and systematics. In addition to resolving the usual hierarchy, the present phylogenetic analysis enabled to resolve the persisting lineage disparity with valid statistical support. Accordingly, divergence incongruences of Primulaceae, Ebenaceae, and Sapotaceae from earlier reports were reinstated in presently inferred phylogeny, which further supported the latest transcriptome-based relationship of the corresponding group. Various SSR motif characteristics emerged following the recognition of the evolutionary pathway. Numerical variation in tetranucleotide repeats showed even intraspecific or varietal differences in Camellia sinensis. Validation of plastome microsatellite-based polymorphism among the related taxa might pave the way for future phylogenetic and population studies of this economically important group.

Opis:: There have been several efforts to plant trees in Uganda but the rate of tree planting has remained low perhaps due to coercing farmers to plant the tree species against their preference. In this study, the tree species’ preferences of farmers in Albertine rift are presented. Key informant interviews, focus group interviews and semi-structured household survey questionnaires were used. A sample of 218 households was selected randomly to include both tree farmers and non-tree farmers in Kiryanga Sub County. The descriptive summaries and content analysis were used in data analysis. Results indicate that Eucalyptus spp., Pinus spp., and fruit trees were most preferred. Farmers have different tree species’ preferences due to the benefits obtained from them. Provision of these suitable tree species’ seedlings will highly incentivize and enhance tree planting in Uganda.

Opis:: The study was conducted in the Górzno and Czarny Bryńsk Forest, ranges which belong to the Brodnica Forest Dis-trict. Brunic Arenosol (Dystric) soils predominate in the Brodnica Forest Division (over 77% of the total area). The aim of this study was to analyze the granulometric composition, the organic matter content and pH values in H2O and KCl at three genetic horizons of soils (A – humus, B – sideric and C – parent material) within the crown extension of four tree species: English oak, European beech, Scots pine and Norway spruce. Silt and clay had a signifi-cantly higher share of A-horizon compared with B and C hori-zons. Soil samples collected under the crowns of Norway spruces were characterized by a significantly higher percentage of sand and a significantly lower percentage of silt than soil samples col-lected under beech and pine trees. In the analyzed soil horizons, pH values increased significantly with depth regardless of tree species. Tree species had a significant effect on the pH of the analyzed soils and the organic matter content of A horizon. Soil samples collected under the crowns of Norway spruces had sig-nificantly lower pH values than those collected under pine trees. Soil samples collected under the crowns of Norway spruces had significantly higher organic matter content than those collected under oak trees. There was a very high negative correlation be-tween organic matter content and the values of pH measured in 1 M KCl, and a high negative correlation between organic matter content and the values of pH measured in H2O suspension.

Opis:: This study was used to assess public opinion of the economic and ecological importance of various tree species in Kaduna Metropolis, Kaduna state. A total of one hundred (100) questionnaires were randomly administered among four purposively selected towns (Angwa-Rimi and Kawo new extension in Kaduna North and Bar’nawa and Sabo in Kaduna South) within the two major local governments in the study area. Twenty-five (25) questionnaires were randomly distributed across age and sex in each of the four (4) selected towns. Of these, ninety were retrieved for analysis. Data analysis was achieved through descriptive analysis. This included frequency distribution tables, percentages and charts. The results show that the majority of the respondents were aged between (21-30) and (31-40) years, these figures representing (44.4%) and (30.0%), respectively, of the entire study population. In addition, most had secondary education (53.3%). In the stated opinions, Meliaceae occur most often. Other trees species identified in the study area include Eucalyptus spp, Azadiracta indica, Psidium guajava, Terminalia catapa, Mangifera indica, Anacardium occidentalis, Khaya senegalensis, Gmelina arboria, pinus spp, Carica papaya, Moringa olifera, Gliricidia sepium, Ficus spp, Afzelia spp, Balanite eagyptiaca, Borassus aethiopum, Persae americana, Polyantha longifolia etc. The following characteristics mark these tree species out as being economically and ecologically important: fast growth, deep rooting pattern, coppicing ability, ability to produce large crown size, tolerance to adverse weather condition, ability of trees to produce broad leaves for shade production, erosion protection, ability to provide fruits, aesthetics and beautification values. In conclusion, urban tree planting is a potential strategy to ameliorate ecological and economic concerns; thus, there is need for the dwellers in the study area to intensify efforts towards planting trees around their houses. Without this, the influx of people, urbanization and industrialization will create deleterious environmental conditions in the study area. It is recommended that efforts to make the populace aware of the economic and ecological significance of urban trees be intensified.

Opis:: Systematic phenological observations have been carried out in the Dendrological Garden of Agricultural University of Poznań, Park Solacki, Lasek Golęciński, Przybyszewskiego Street, for two years (2003, 2004). The selected species of deciduous trees, as Betula pendula, Corylus avellana, Platanus x hispanica. There was interdependence between the course of flowering process and weather conditions. Long and frosty winter at the turn of 2002/2003 and subzero mean temperatures in the first quarter of 2003 delayed vegetation. Rapid coming of early spring in the year 2004 accelerate the development of generative organs. Each year spring ground frost during flowering did not inhibit this process. All the investigated tree species are anemophilous and produce large amounts of allergenic pollen grain. They cause allergic reactions throughout the whole period of pollen discharge. Male inflorescences in Corylus avellana, blooming very early, are one of the first plants causing allergic reactions., Betula pendula is the next to bloom, followed by Platanus x hispanica. Observations of phenological phases may provide useful information forecasting the beginning of the period of increased pollen concentration in air.
Systematyczne obserwacje fenologiczne byly prowadzone w Ogrodzie Dendrologicznym Akademii Rolniczej w Poznaniu, Parku Solackim, Lasku Golęcińskim i na ulicy Przybyszewskiego w latach 2003-2004. Obiektem obserwacji byly wybrane gatunki drzew - Betula pendula, Corylus avellana i Platanus x hispanica. Analizie poddano zależność pomiędzy warunkami pogodowymi a procesem kwitnienia. Długa i mroźna zima na przełomie 2002/2003 roku oraz ujemne średnie temperatury w pierwszym kwartale 2003 roku opóźniły wegetację. Wczesne nadejście przedwiośnia w roku 2004 przyspieszyło rozwój organów generatywnych. Coroczne wiosenne przymrozki w okresie kwitnienia nie zahamowały tego procesu. Wszystkie badane gatunki drzew są wiatropylne i produkują duże ilości alergogennych ziarn pyłku. Powodują one reakcje alergiczne przez cały okres swego pylenia. Kwiatostany męskie Corylus avellana zakwitające bardzo wcześnie, są jednymi z pierwszych roślin powodujących reakcje alergenne. Następnie zakwita Betula pendula, a potem Platanus x hispanica. Obserwacje faz fenologicznych mogą być przydatnymi informacjami zwiastującymi zbliżanie się okresu zwiększenia stężenia pyłku w powietrzu.

Tytuł:: How do monocultures of fourteen forest tree species affect arbuscular mycorrhizal fungi abundance and species richness and composition in soil?

Opis:: Despite the presence of arbuscular mycorrhizal fungi (AMF) in temperate forests, knowledge concerning their diversity and interactions with plants is still insufficient. Therefore, we studied the impact of overstorey species identity on AMF abundance and species richness and composition in relation to herbaceous plant cover and soil chemical properties. The effects of 14 tree species grown for 48 years in monospecific plots in the Siemianice Experimental Forest (western Poland) were compared, including the following groupings: deciduous vs coniferous; native to Poland/Europe vs alien; forming vs not forming arbuscular mycorrhizas (AM). Coniferous tree plots were characterised by lower pH values, plots with deciduous trees by higher concentrations of total Ca and exchangeable forms of Ca, K and Mg. AMF abundance in soils and roots increased along with increasing soil alkalinity and macronutrient levels. Concentrations of the PLFA 16:1\omega5 AMF hyphal biomass marker were higher in the soils of deciduous and AM-type tree species than those of coniferous and non-AM types. In addition, concentrations of the NLFA 16:1\omega5 AMF spore biomass marker were higher in the soils of deciduous tree species. No significant differences were found between groups of native and alien tree species. AMF spore and species numbers were low in comparison to other unforested ecosystems, averaging 77.5 and 1.2 per 50 g of soils, respectively. The presence of 8 AMF species, both widespread (e.g. Funneliformis constrictus) and rare (Acaulospora cavernata) was revealed. Significant divergence in AMF species composition was noted between plots of deciduous and coniferous species. Our study showed that tree species identity, considered as a single factor, has only a slight impact on determining AMF community characteristics. The disparity between AMF community characteristics results from the effects of several factors, as pH and element concentrations in soils, acting within tree species groups.

Wydawca:: Instytut Badawczy Leśnictwa (Forest Research Institute), Komitet Nauk Leśnych PAN (The Committee on Forestry Sciences of the Polish Academy of Sciences)
Cytata wydawnicza:: Folia Forestalia Polonica, series A, 2011, Vol. 53 (1), 43–51
Opis:: Przemysław Szmit
The ecological stability of forests in the face of extremes of climate is primarily determined by the adaptability of the current tree species, the diversity of forest structures and the influence of additional stress factors (phytophagous, phytopathogenous, eutrophication and others). Against the background of the local conditions in the Northeastern German Lowlands, the adaptability of the main tree species for the period of the present climate scenarios (max. 50 years) will be evaluated, using the example of the federal state of Brandenburg. During this period, the Scots pine will remain the most important tree species from an economic point of view. The significance of pioneer tree species will grow in the future, for example due to their short generation time and their high rates of fructification. The competitiveness of the oak species and the common beech will continue to differ in terms of location. Different risk provisioning options for action for forest management will be introduced.

Tytuł:: Symptoms of the naturalisation of the Turkey oak(Quercus cerris L.) in Polish forests
Autorzy:: Kiciński, Piotr

Wydawca:: Committee on Forestry Sciences and Wood Technology of the Polish Academy of Sciences, Forest Research Institute
Opis:: Przemysław Szmit
War, can be found in some 20 localities, mostly in the western part of the country. Because this species is capable of a natural renewal in a woodland environment, a research was made to find in what conditions and how far it undergoes spontaneous naturalisation. Three study sites were chosen in the forests of central Wielkopolska. An inventory was made of mature stands of the Turkey oak and its generative renewal. Plant communities in which the young generation of Q. cerris usually appears were characterised. It was found that self-sown seedlings of this species grew at a distance of up to 2,500 m from parent trees. The highest number and the greatest density of specimens of the secondary generation of the Turkey oak were found at ‘Racot’, which is a 100-hectare, mid-field woodland island where mesotrophic habitats predominate and where about 50% of the area is occupied by communities with manmade pine tree stands. At all sites, Q. cerris penetrates primarily this type of deformed phytocoenoses, developing mostly on former farmland. It has become a permanent component of the underbrush and undergrowth in them, and in some places, it also makes up the tree layer. It was observed that in the study area, it penetrated the woodland environment much more effectively than Quercus rubra, considered an invasive species. The expansion of the Turkey oak in several of the examined localities can be regarded as a basic manifestation of its naturalisation in places where there are phytocoenoses with pine stands in broad-leaf forest habitats in the neighbourhood of parent trees.
