“…In general, research focuses on the morphological characteristics of characters on fruits and flowers, chemical composition, antioxidant activity (Brindza et al, 2011(Brindza et al, , 2014Muntean et al, 2012;Oleárová et al, 2013), conservation of genetic resources (Mendel et al, 2019;Avagyan et al, 2020) and other possibilities of practical use. Pumpkin also produces a lot of pollen, which can be collected by bees in the form of bee pollens (Chlebo et al, 2017).…”

The study aimed to determine the variability of some morphological characters on fruits of selected plants within the population of ESO variety of Styrian oil pumpkin (Cucurbita pepo var. styriaca). For experimental evaluation, we used two years (2020-2021) measurements of 165 selected fruits from individual plants grown in the field conditions in Kolíňany (Slovak Republic). We determined for all samples the range for the weight of fruits (521.50-12744.70 g), length of fruits (85.00-285.00 mm), width of fruits (114.00-320.00 mm), exocarp thickness on the left side (0.10-4.86 mm), exocarp thickness on the right side (0.33-4.56 mm), pericarp thickness on the left side (9.13-57.02 mm), pericarp thickness on the right side (9.77-46.05 mm), placenta weight (89.00-870.00 g), fresh seed weight (17.30-638.50 g), seed weight after drying (4.53-187.36 g), seed length (12.91-24.00 mm), seed diameter (6.56-14.41 mm), seed thickness (0.41-3.62 mm), the weight of one thousand seeds (15.41-475.66 g). The results document that in our collections there are plants suitable for the next cultivation, and further selective improvement. In practice, only seeds of the ESO variety are used for oil production. The percentage of the weight of the seeds from the total weight of the fruits is only 3-4%. Other parts of the fruit remain in the field after harvesting. After their decomposition and ploughing into the soil, they improve the physico-chemical properties of the soil. However, the results of the experiments confirm that many parts of the fruit, such as the pulp and the placenta, are important raw material sources for use in the food industry, pharmaceuticals, cosmetics, and other areas. When growing butter pumpkin in large areas, it is also possible to collect and use flowers and young -unripe fruits from the plants during the growing season in the food industry and other areas.

“…[16,17] The botanical origins of the pollen collected according to the floristic structure of the region where the honey bee colonies are located also vary. [15,18] In terms of sustainable beekeeping, the long flowering period of the flora and the high diversity cause the bees to multiply. It is very important to know the nectar and pollen source plants around the apiary and to investigate their existence.…”

Climate change affects plant phenology and, as a result, can damage nectar and pollen sources, which are the basic needs of bees during flowering. This situation creates nutritional stress for bee colonies in the region. Changing climatic conditions, the use of agricultural lands adversely affects honeybees and beekeepers. The aim of this study is to determine the annual development performance of fixed honeybee colonies linked with the chemical and mineral profile of bee collected pollen. According to the research findings, in terms of colony development parameters, the number of bee frames (9.17) was found to be at the highest level in May, and in terms of brood area (4652.35 cm 2 ) in April (P < 0.05). March, April, and May are the most abundant months in terms of pollen collection of the colonies (P < 0.05). The pollen samples collected are rich in potassium, sodium, calcium, magnesium, silicon, and iron. There are differences between months in terms of pollen sources and mineral levels. Especially in stationary beekeeping, additional feeding is required during critical periods. The existing flora is insufficient for the future of the honey bee. In periods when the flora is weak, important plants for the honey bee should be grown in the region.

“…(Radović et al, 2016), and Cichorium intybus L. (Adamchuk et al, 2017). Size, shape, surface morphology, and ultrastructure of pollen grains are of great importance in the characterization of the pollen grains (Erdtman, 1966;Fogle, 1977;Martens and Fretz, 1980;Brindza and Brovarskyi, 2013;Dyakova, 2014;Brovarskyi et al, 2017;Chlebo and Adamchuk, 2017).…”

in Nitra using an electron microscope Carl Zeiss LS 15. The measurement of morphometric parameters was carried out on 50 pollen grains from each phenotype using the AxioVision Rel. 4.8.2.0 program. The measurements were made in micrometer (μm). The length of polar axis (P) and the equatorial diameter (E) of grain, P/E ratio were measured and their variation was compared among studied genotypes. SEM investigations showed that the pollen grains are radial-symmetrical, isopolar, oblong-ellipsoid and 3-and 4-colporate. Texture is sinuous-tuberculate in equatorial zone and finely bumpy in polar zone. The polar axis and equatorial diameter of pollen grains values were varied from 34.16 to 50.14 μm and from 16.10 μm to 25.71 μm, respectively. This study showed that there were differences among the phenotypes in all measured factors. It is known that phenotypic variability is an evolutionarily fixed response of any group of organisms with a constant genotype to changes in environmental conditions and it is adaptive. Therefore, our research suggests that all individuals forming the introduction population of Aronia mitschurinii are sufficiently adapted to the conditions of M.M. Gryshko National Botanical Garden of NAS of Ukraine.
