Linear assessment of the type and body development provides very important information on the total value of animals for the purpose of breeding animals selected and classified into classes. Determination of the average values of exterior parameters, especially non-measurable traits, is useful in defining breeding objectives and formulating effective plans and programs. Given that previous studies found statistically significant differences among daughters of Simmental bulls for some properties of the exterior, the objective of this paper was to compare linear type traits and body development of daughters of Simmental bulls in the Rasina region. Based on linear type traits and body development, the most significant results were achieved by daughters of bull No. 1464 (Ralfus) for the frame, muscularity and form, and by daughters of bull No. 1488 (Hormaz) for udder appearance. If each attribute is analyzed separately, bull No. 1411 (Horau) is equally significant for the traits for which its daughters showed the best performance.

The aim of this study was the evaluation of phonological, fruit and chemical characteristics of 6 traditional pear varieties ('Mustabej', 'Patliganka', 'Ljubichica', 'Tatlikuti', 'Shaldanka' and 'Ekshikuti') typical of the Prespa region in Macedonia. These varieties flowered in the second half of April up until the end of April. 'Shaldanka' and 'Ekshikuti' flowered the earliest. According to ripening time, 'Mustabej' was characterized as a summer variety, 'Patliganka' and 'Ljubichica' as autumn varieties, 'Tatlikuti' and 'Shaldanka' as late-autumn varieties, and 'Ekshikuti' as a winter variety. These varieties had a medium-long fruit stalk except 'Tatlikuti'. All varieties contained a low quantity of seeds in the fruit. The biggest fruits, with the longest fruit stalk and the highest value of stone cells were characteristic of 'Shaldanka'. 'Mustabej' had the highest value for fruit firmness. 'Tatlikuti' formed fruits with the best flavor.

The assessment of the threat of forest fires usually includes identification of factors and quantification of risk levels. This work presents an approach to modeling the risk of forest fires caused by climate impacts. Climate Impact Assessment is based on the significance of air temperature, rainfall and relative air humidity. The analysis is based on the meteorological data obtained from 26 meteorological stations in Serbia for the period from 1981 to 2010. The analysis is used to predict the areas where the expected rate of fire is high. The method is simple; it describes the key variables for the risk under climate impacts and the spatial pattern of risk. It is suitable for operational use by authorized services. The risk of forest fire is classified as negligible, small, medium and large. The database and analysis results were used to build the matrix of risk assessment of forest fires in Serbia. A great part of the territory of Serbia is relatively highly sensitive to forest fires. The lowest consequences of climate impacts are visible in the areas of Kopaonik and Zlatibor. In Serbia, there is no place where there is a negligible risk of fire. Further research, especially in terms of the relationship between climate change and the adaptive capacity of existing forest ecosystems, species and existing genotypes, is urgently needed in Serbia.

The growth, development and the prevalence area of plant species are determined by a variety of influences. Plants are increasingly exposed to the different stress factors. Fires in nature can completely destroy the whole forest complex habitats with great biological diversity of many species in a short period of time. This study deals with the effects of a fire, such as heat, to the plants. After the fire, the environment is being changed and some species in areas affected by the fire will appear only after the fire, some species that had existed before the fire, will be developed in accordance with the new conditions, and some species will disappear after the fire. The aim of the study was to assess the sustainability of the natural vegetation in fire conditions, which is important for natural regeneration and nursery production. Fire temperatures cause irreparable damage of the plant functions or of the plant organs. In the analysis of the plant species the frequency of the fire is often more important than the type and intensity of the fire. Regarding possible long fire season in Serbia, as well as the presented statistics data about the number of fires and burnt areas, it can be concluded that there is an evident risk of plant species of fire, which are more common in this region.

Market significance of cucumber for fresh consumption and the new technology of growing make it one of the most attractive vegetable variety. Interest of producers is higher every day, while the selection of new varieties is very low. The aim of this research was the selection of cucumber intended for fresh consumption with good agronomic traits intended for growing in the greenhouses and in the open field. The researchers of the Institute for Vegetable Crops, Smederevska Palanka created new cucumber hybrid which was recognized by Ministry of Agriculture Forestry and Water Management of the Republic of Serbia, Department for Plant protection in 2013, under the name 'Kralj'.
