Different chromosomal forms of Deschampsia antarctica Desv. (Poaceae), including diploids (2n=26), hypotriploid (2n=36–38) and a genotype with an occasional occurrence of B chromosome (2n=26+0-1B) that originated from southern marginal populations (Argentine Islands region, maritime Antarctic) were studied using molecular cytogenetic, morphometric and biochemical methods. FISH analysis revealed variations in the number of rDNA sites between the diploid and hypotriploid plants. The genome size varied among plants with a different chromosome number and was on average 10.88 pg/2C for diploids and 16.46 pg/2C for hypotriploid. The mean values of leaf length of plants grown in vitro varied within a range of 5.23–9.56 cm. The total phenolic content ranged from 51.10 to 105.40 mg/g, and the total flavonoid content ranged from 1.22 to 4.67 mg/g. The amount of phenolic compounds did not differ significantly between the genotypes, while a variation in the flavonoid content was observed for L59 and DAR12. The diploids did not differ significantly among each other in terms of the number of rDNA loci, but differed slightly in their genome size. The individuals of DAR12 carrying B chromosome were similar to other diploids in terms of their genome size, but statistically differed in leaf length. The hypotriploid had both a greater number of rDNA sites and a larger genome size. No statistical correlations were observed between the genome size and leaf length or genome size and accumulation of phenolic and flavonoid compounds. The results of this study suggest that D. antarctica plants from the southern edge of the range are characterised by the heterogeneity of the studied parameters.
Petiole bending in detached leaves of Bryophyllum calycinum was intensively investigated in relation to polar auxin transport in petioles. When detached leaves were placed leaf blade face down, clear petiole bending was observed. On the other hand, no petiole bending was found when detached leaves were placed leaf blade face up. Indole-3-acetic acid (IAA) exogenously applied to petioles was significantly effective to induce and/or stimulate petiole bending when detached leaves were placed leaf blade face down. To clarify the mechanisms of petiole bending in detached leaves of B. calycinum when they were placed leaf blade face down, the effects of application of IAA, ethephon which is an ethylene releasing compound, inhibitors of polar auxin transport such as 2,3,5-tiiodobenzoic acid (TIBA), N-1-naphthylphthalamic acid (NPA) and 9-hydroxyfluorene-9-carboxylic acid (HFCA) and methyl jasmonate (JA-Me) were thoroughly investigated. Ethephon was not effective to enhance petiole bending, suggesting that ethylene derived from exogenously applied IAA does not play an important role in petiole bending in detachd leaves of B. calycinum. This suggestion was strongly supported by the fact that ethephon exogenously applied to petioles in intact plant of B. calycinum had no effect on inducing epinasty and/or hyponasty either (Ueda et al., 2018). Potent inhibitors of polar auxin transport, TIBA and HFCA, and JA-Me were extremely effective to inhibit petiole bending but NPA was not. Almost no petiole bending was observed in excised petiole segments without the leaf blade. Applicaton of IAA to the cut surface of petioles in the leaf blade side strongly promoted petiole bending. Polar auxin transport in excised petioles of B. calycinum was intensively investigated using radiolabeled IAA ([1-14C] IAA). Clear polar auxin transport was observed in excised petiole segments, indicating that auxin allows movement in one direction: from the leaf blade side to the stem side in petioles. When detached leaves were placed only leaf blade face down, transported 14C-IAA was reduced in the lower side of the excised petioles. These results strongly suggest that transport and/or lateral movement of endogenous auxin biosynthesized or produced in the leaf blade are necessary to induce petiole bending in detached leaves of B. calycinum. Mechanisms of petiole bending in detached leaves of B. calycinum are also discussed in relation to polar auxin transport and lateral movement of auxin.
We have developed an effective protocol for in vitro micropropagation in order to obtain large numbers of identical plants and another protocol for in vitro polyploidization of Ajuga reptans, based on the use of oryzalin. Two donor plants of A. reptans (AR 4, AR 7) were treated with 0, 1, 5, 10 μM oryzalin for 2 weeks. The analysis of the ploidy level of these plants was verified by flow cytometric analysis using the internal standardization method. The effects of polyploidization on growth as well as morphological and stomatal size were also measured. After in vitro polyploidization, some plants became tetraploids or octoploids. The most efficient conditions for inducing tetraploidy were the treatments with 10 μM oryzalin.
Nowadays, the ubiquity of changes determines a new approach to programming development. In this situation, it is necessary to update the strategy of socio-economic development in many cities. The aim of the paper is to present the process of updating the city’s development strategy on selected examples (Katowice, Cracow, Poznań, Warsaw and Wrocław), through the prism of the scale and tools of public participation. Wrocław is a centre that particularly approached the implementation of the megatrend of public participation in the work on updating the development strategy. The paper delineates differences between public consultations and real public participation. The following research methods were used in the study: literature research, analysis of source texts, benchmarking and comparative analysis. The time horizon covers the period of public participation in the documents’ construction and is different for particular cities selected for analysis, however, it falls in the years 2013-2017.
Regeneration – an integrated process of activities undertaken in the spatial, social and economic dimensions – should lead to the improvement of the living conditions of inhabitants of degraded urban areas. The European Union in 2007- 2013 allocated financial resources for this purpose in the form of JESSICA initiative which is based on financial engineering mechanism. Experiences gained so far allow conclusions to be drawn that JESSICA is a highly fi nancially-effi cient instrument but, however, not always delivers the desired outcomes in the spatial and social sphere. The scope of projects often is limited to infrastructural investments and does not reflect the complexity of regeneration process. In the article the authors analyse experiences of the five Polish regions with the use of JESSICA, point out main problems and formulate recommendations for sustainable urban policy.
The article reviews the integrated territorial investments carried out in the Opolskie Voivodeship in the financial perspective 2014-2020. The object of the analysis was the Opole Agglomeration as the only of five functional areas of the Opolskie Voivodeship, where beneficiaries of funds from European Funds are located within this investment policy development policy.
Despite significant changes of a political, legal and economic nature, despite clearly expressed intentions, the natural environment of most areas of Europe is further degraded. Therefore, it is necessary to adopt effective solutions, and one of the possibilities of determining the directions of support is the pro-ecological nature of the regional innovation strategy, which will allow transfer of much larger funds to support eco-innovation. The work is a case study. The aim of the research presented in this work is to show the relationship between the provisions of the Regional Innovation Strategy of the Podkarpackie Voivodeship for 2014-2020 for intelligent specialization (RIS3), and the assumptions of the five-helix concept, and the justifi cation for its use in future, in the form of a developed regional eco-innovation strategy.
Housing resources as an element of material infrastructure determine socio-economic development on a local, regional and national scale. Their economic and physical accessibility affects the development of human, social and relational capital, determines the competitiveness of the territory and can be seen as a generator of income both in the individual sense and in relation to the whole society. The article has a theoretical character and its aim is to identify the relationship between satisfying the housing needs of local communities and the development of territorial capital. The article also analyzes factors that allow the qualification of housing resources as a strategic resource for the development of a territory.
Who owns the city? Do the inhabitants of modern cities have a reflection on their place of everyday life? Do they treat the city as commons? Do they feel co-responsible for the directions of development of their cities? Answers to the above questions have far-reaching consequences for urban development policy. They are the basis for assessing the ongoing democratization processes in the local government sphere. They also reveal important aspects of the condition of civil society. Although, on the basis of various indicators the trend is positive, it seems that the awareness of the role of the citizen versus the ordinary resident is poorly rooted in the attitudes of the Polish people. And the lesson of citizenship is still an undisrupted task for a large part of the inhabitants of our country. The greatest hopes lie in the generation of young and educated Poles who, through the development of participative management mechanisms, are becoming more aware of the possibilities of citizens’ influence on urban policy. The article is an attempt to answer the above questions based on literature review, current press articles and empirical studies conducted among a group of students.
Rural areas have great potential, which properly supported can signifi cantly accelerate the socio-economic development of the country. However, the resources and values of individual areas are spatially diversifi ed, which means the diversity of development challenges and the necessity to diversify the instruments of local development policy as well as the territorialisation of development policy. The need to deal with development issues in connection with the development of urban functional areas and, more broadly, node regions, remains unchanged for all types of rural areas, which means the necessity of joint planning of spatial development, implementation of common development strategies of the entire functional area and pursuit of common socio-economic goals. The endogenous theory of local development remains valid, but it must be based on resources that go beyond the administrative boundaries of a single municipality. The need for network local development planning applies in particularly to peripheral rural areas, since rural municipalities often do not have sufficient economic potential to stay competitive even on a local scale. Only in partnership with other municipalities, within the framework of nodal regions, they can implement more eff ective competitive strategies. Another aspect of the network cooperation is the need to involve non-public entities into local economy. Establishing partnerships for the implementation of development goals may increase the chances of achieving a favourable competitive position and implementation of effective development strategies.
The paper concentrates on the possibilities of checking the extent to which cities meet the smart city concept. The presented concept concentrates on one of the main smart cities characteristic: smart environment. This paper is a result of joint work of specialist from two diff erent areas: management and environmental protection. The interdisciplinary character of the paper is characteristic for smart cities.
The social, economic and environmental zone is constantly changing in terms of factors aimed at improving the quality of life, economic and technological development of the city while at the same time rational use of resources of the natural environment. Change as a dynamic factor is an impulse for creating new behaviors of residents and interactions between them and public and private sector entities. The article attempts to systematize selected contemporary concepts shaping the city, emphasizing the coherence of their assumptions and the scope of the issues discussed. Looking for features that characterize the city, which balance the needs and expectations of its users.
The research issues discussed in the paper concentrate on the participation of the municipal services sector in shaping local development in the commune. The aim of the study is to verify the actual level of involvement of this sector in the development process of the commune, and the thesis is: “The activities of the municipal services sector are one of the factors shaping local development in the commune.” The basic research method is a critical review of domestic and foreign literature and participant observation.
The aim of the article is to present international economic integration as one of the mega trends that infl uence on the redefi nition of the factors of socio-economic development. The research procedure includes three stages. In the fi rst stage, the most important modern mega trends of socio-economic changes are organized in a synthetic way. In the second step, the genesis and changes of the process of international economic integration are elaborated. In the third stage, the infl uence of international economic integration on the changes of factors of socio-economic development is systematized. This study is being carried out as part of the FORSED research project (http://www.forsed.amu.edu.pl) fi nanced by the National Science Center as part of OPUS competition 10 – 2015/19/B/HS5/00012: New challenges of regional policy in shaping the socio-economic development factors of less developed regions.
Recent works of the authors, concerning the future of urban regions, are synthesised in the paper. Three methodological paths – focused on exploring and creating the future of urban regions – are the backbone of the presented work. Within the fi rst path, creation of regional future by applying the concept of intellectual and strategic challenges is recommended. Second path introduces a new perspective for the future, based upon vehicles. A new philosophy of urban and regional growth emerges here. Third path is a new approach towards creation of regional specialisations in a contemporary notion of technological and creative economy.
The concept of endogenous development assumes the use of specifi c resources of the region, difficult to copy, to its development, and even to gain a competitive advantage in a wider dimension. This concept has been used in the provisions of the Regional Innovation Strategy of the Podkarpackie Voivodeship for 2014-2020 for smart specialization (RIS3), especially in relation to leading smart specialization the quality of life, in the areas of: production and processing of ecological, regional and traditional food; renewable energy and distributed energy; agrotourism and ecotourism. It was targeted at the development of the entire region, not only the leading urban centers. The special role of the food economy lies in the need to guarantee food security and food sovereignty in the region. This issue is of strategic importance.
One of the current challenges in transport is e-mobility, understood as electromobility, ecomobility and mobility economics. E-mobility is nowadays a key focus area of socio-technical change, in terms of attention from policy makers as well as from industry and the public. The societal challenges ahead, in particular climate change put increasing pressure on the current mobility system, due to its tremendous environmental impact. Furthermore e-mobility is seen as major economic opportunity for the automotive industry. In this context, based on the available literature and documents and practical solutions implemented already in cities and agglomerations, the paper discusses the fundamental challenges that cities are to face in the context of the current megatrends. This process will engage diff erent stakeholders in order to make this concept become a reality.
In this paper experiences and manifestations of territorialisation of European cohesion policy, with special concentration on Poland, who is the biggest benefi ciary of that EU policy, were presented. Regional level is having strongest impact on success of territorialisation of public policies, but general conditions are shaped by central level, and also local level role is increasing, including cities and urban policy. Later an analysis of possibilities and conditions of EU cohesion policy territorialisation was elaborated, evaluating favourable and unfavourable factors. Conclusions are rather pessimistic, because there are many restrictions and preliminary preconditions of effi cient and eff ective decentralisation of EU structural intervention.
The paper indicates the signifi cance of the development policy territorialization for an enhancing competitiveness of cities and regions. The characteristics of such a policy allow revealing of the nature of territorial instruments. The authors, referring to their consulting practice and the research work done for the Ministry of Development, frame their recommendations. Those recommendations constitute the guidelines for amendment of territorial instruments in the context of National Regional Development Strategy actualization.
The article is a review of the current theoretical achievements in the context of the discussion on the shape and validity of the property tax reform in Poland, indicated in the endogenous development of municipalities. The conclusions contained in the article are an attempt to join in a scientifi c discussion on the subject of property taxation. They constitute a proposal of formulated recommendations necessary from the point of view of legitimacy of collecting property taxes and the implementation of the new system of ad valorem tax.
The concept of social capital is gaining increasing popularity among economists and governance practitioners. This is due to the recognition of the fact that a high level of social capital is important for the creation of socio-economic development of countries or territories – economic areas with a high level of connections between entities, organisations and residents. The formation of social capital, understood as the ability to cooperate with various social groups and operate efficiently within these groups, depends on the political system as well as the adopted norms and attitudes, education, styles of management in business organisations and public sphere entities, family ties, motivation to act, etc. The aim of the paper is to indicate various limitations of social capital development and to demonstrate that it is important to involve different communities in its formation In addition, attention is drawn to the fact that social capital generates externalities that are essential for the efficiency and eff ectiveness of governance in territorial systems, both in the economic and public utility sphere.
The region’s development potential is a set of endogenous features that determine the growth of the local economy. It supports the development of knowledge, innovation and eff ective competition on global markets. The publication argues that saturation with potential may not be enough to cause economic growth. The distribution of potential is also important: concentration is its catalyst. The study proposes a method for measuring the concentration of potential. It has also been shown that the size of the regional economy depends on the distribution of potential in the region.
There are numerous diff erences between EU Member States, e.g. related to geographic location, language, culture, etc. The main difference can be primarily found in the level of development of individual regions and voivodeships in Europe. Poor regions and voivodeships in the conditions of growing competition lose their distance to the wealthy ones. The European Union, having this in mind, has given a priority in its regional policy to reduce the disparities between regions by providing aid through the socio-economic cohesion policy to neglected provinces. This problem is of a particular importance in the Polish context due to the large diff erences between the voivodeships. Large disproportions are visible especially between voivodeships of Eastern Poland whose potential, especially innovative potential, is among the weakest in Poland and in the EU. The aim of the article is to review the concepts of innovation, to present the innovative potential of particular Polish voivodeships in 2020 and to defi ne innovative potential’s signifi cance in the development. For the calculation of the synthetic index, there was used a non-model method.
