PHENOLOGICAL CHARACTERISTICS AND GLOBAL TREE ARCHITECTURE OF THE PEAR GERMPLASM FROM BOSNIA AND HERZEGOVINA IN EX SITU CONDITIONS

Fruit germplasm plays an important role in the global agrobiodiversity and is a source for both a direct use of fruit genetic resources as well for fruit breeding programme. The ex-situ field collection is still the main way to successfully conserve fruit germplasm. Thirty pear accessions from Bosnia and Herzegovina were characterized during three years in the ex situ collection maintained by the Institute of Genetic Resources of the University of Banja Luka. The following characteristics were determined: flowering time, harvest maturity time and global tree architecture. The obtained results showed that 53.3% of pear accessions flowered during all three years, 40% of them during two years and 6.7% of them during only one year. The most present tree architecture form was upright. According to the harvest maturity time, extremely early accessions were the most represented, than early, medium and very early pear accessions. Conserved pear germplasm in this ex situ collection represents a valuable material for direct use and future breeding programmes

Morphological characterization of buds being donors of apex for molecular confirmation of differentiation of meristem into permanent tissues of stone fruit trees (Prunus sp.)

Molecular confirmation of the process of differentiation of meristematic tissue of plants is primarily based on histomorphological characterization of the tissues carrying these processes. For perennial plants - fruit trees, the knowledge of these processes is important to define runtime type and pomotechnical treatments but also to identify the genes responsible for determination of the apices into a generative phase of differentiation. Which apex extraction techniques will be applied depends on the structure of buds, i.e. whether an apex differentiates only into generative elements - pure flower buds, or the differentiation goes into two directions: differentiation of leaf primordium with axillar meristematic dome and differentiation of generative elements of flowers in the peak or lateral zone of an apex - mixed buds. The fruit trees of the genus Prunus have purely flower buds and for this purpose the whole apex is taken, between protection - cover leaves, on lateral positions of all collateral buds at shoot nodes. The moment of initiation of determination and the dynamics of differentiation of generative buds are different at different type of shoots on a tree. It is therefore necessary to know the shoots growth cessation time which is in correlation with apex determination. Fruit trees of the genus Prunus are ending the growth of shoots by rejection of shoot peaks, and the cast away time depends on the type, length and the position of shoots

Genetic Diversity of Wild Apples and Pears in the Forest Park of Starčevica, Banja Luka, Bosnia and Herzegovina

The increasing fragmentation and degradation of forest habitats and the hybridization with cultivated varieties potentially threaten the genetic integrity of wild apple (Malus sylvestris /L./ Mill) and wild pear (Pyrus communis L.). Wild apple and wild pear have been included in the European Forest Genetic Resources Programme – EUFORGEN priority lists for development of conservation strategies. Researches are required into the genetic diversity and the structure of local populations to determine the most suitable conservation policies for these species at different scales. In this study, the RAPD markers were used in order to evaluate interspecies genetic similarity of wild apple trees and wild pear trees from the Starčevica Forest Park, Banja Luka, Bosnia and Herzegovina. Primers OPA-05, OPA-07, OPA-09, OPA- 10, OPG-03, OPG-11, OPG-12, OPG-13 and OPAC-03 were used to analyse genetic similarity of wild apple trees, while OPA-01, OPA-03, OPA-05, OPA-07, OPA-08, OPD-04, OPD-14, OPG-03 and OPG-06 were used to analyse genetic similarity of wild pear trees. There was a high level of polymorphism among the analysed wild apple trees, as well as among the wild pear trees, demonstrating a considerable richness in terms of wild apple and wild pear genetic resources in the Starčevica Forest Park. The significant genetic diversity of wild apples and wild pears is present between different test polygones, while when it comes to diversity within the test polygons, it can be concluded that very similar genotypes of wild apples and wild pears generally prevail within a polygon

A new fuzzy risk management model for production supply chain economic and social sustainability

The issues of operational, organisational and process risk assessment in supply chains (SCs) are the most usually analysed, while other risk groups (like economic and social risks) are not taken into account, even though they have a critical effect on the competitive advantage and SCs sustainability over long time periods. The determination of risk value that may arise due to the materialisation of each defined risk factor (RF) is based on the assessment of the severity of RF consequences and frequency of RF occurrence. These judgments are obtained by decision makers and modelled by using fuzzy set theory. The relative importance of RFs are stated by fuzzy pair-wise comparison matrices in compliance with fuzzy analytical hierarchy process (FAHP). The risk level of SCs could be obtained in an exact way by applying fuzzy logic. The proposed model, to be presented in this paper, provides a possibility to easily and simply determine risk level from the automotive industry SC and to propose appropriate management initiatives that should lead to a reduction or elimination of RF influenc

Yield Potential of Long Bearing Shoots of Ten Plum Cultivars (Prunus domestica L.)

The yield potential of ten plum cultivars ('Čačak's Beauty', 'Čačak's Best', 'Čačak's Fruitful', 'California Blue', 'Elena', 'Hanita', 'Katinka', 'Renclode Althan', 'Stanley', and 'Top'), exhibited through the structure of buds on long bearing shoots, was analyzed under the agro-ecological growing conditions of the Banja Luka region for two fruiting seasons (2012 and 2013). Long bearing shoots with collateral buds were the most productive type of fruiting branches, which is why the structure of buds on these branches is the basis for defining specific cultural measures in order to boost yield potential. Based on the established structure of buds on the nodes along the long bearing shoots and the established yield potential, the plum cultivars evaluated were classified into 4 groups: 1) cultivars with a predisposition to have a high yield potential, without need for specific treatments in fruiting control ('Čačak's Beauty' and 'Top'); 2) cultivars with a predisposition to have a high yield potential with the application of cultivar-specific cultural measures for control of fruiting ('Čačak's Best', 'Elena', and 'Stanley'); 3) cultivars that require differentiated cultural measures in the control of yield potential for regular fruiting ('Čačak's Fruitful', 'California Blue', and 'Katinka') and 4) cultivars that require innovative growing systems and specific cultural treatments to control fruiting ('Hanita' and 'Renclode Althan')

Traces of biologically significant radionuclides in milk and their share in total milk radiological load

Stoga su u ovom radu prikazani rezultati koji se odnose na nivoe aktivnosti prirodnih i proizvedenih radionuklida u mlijeku iz podrinjsko-kolubarskog regiona i njihovi komparativni faktori.Continual milk quality control has become necessary due to the inidispensability of this food product in human nutrition, with special attention being paid to the radiological expertize of milk. This investigation, therefore, has been carried out to determine natural and produced radionuclide (K-40, Cs-137, Sr-90) levels and their comparative factors in the milk from the Podrinje-Kolubara region

Morphological and pomological characteristics of wild pears in the northwestern part of the Bosnia and Herzegovina

The aim of this research is to examine the morphological and pomological characteristics of the wild pear population in the northwestern part of Bosnia and Herzegovina with the purpose of allocating genotypes for breeding programs of varieties and rootstocks. During 2012 and 2013, the study of the wild pear characteristics was carried out on the localities of: Banja Luka, Manjača, Potkozarje and Kozara. This research included morphological characterization of vegetative organs and pomological characterization of the fruits of all the selected genotypes. The shape of leaves in all the examined genotypes was elongated. The study of wild pear populations in the Banja Luka region has shown that wild pears are characterized by mostly smaller fruits, rounded form, while a few genotypes had fruits of elongated and flattened shape. Fruit weight varied from 7.44 g to 21.47 g and 73% of genotypes had fruit weight of over 10 g
