Salinity leads to lower productivity of agro- and biocenosis, a decline in biodiversity and, as a result, significant economic losses. For the most important oil culture – sunflower (Helianthus annuus L.), primary reactions to salt stress are almost unexplored. This paper analyzes the impact of a wide range of NaCl concentrations on the growth of the main root of sunflower sprouts and the development of programmed cell death processes in trichoblasts. Experiments have shown that sunflower plants are relatively resistant to salinity (NaCl). They were able to grow at the level up to NaCl 250 mmol/L in the environment. Significant symptoms of programmed cell death were detected only at high concentrations of NaCl 250 –500 mmol/L. Previously undescribed in the literature, the reaction of reducing the number of symptoms of programmed cell death under150 mmol/L NaCl treatment (medium salt stress level for sunflower) was determined. An inhibitory analysis of the NaCl-induced potassium flux showed that it was only 15 % inhibited by specific potassium channel antagonists (Ba2+ ). This indicates a low proportion of potassium channels and the dominant role of non-selective cation channels in providing NaCl-induced potassium loss in Helianthus annuus L. plants.","PeriodicalId":437681,"journal":{"name":"Journal of the Belarusian State University.

Comparison of the obtained data with previously published information on the nature and range of variability of the North American taxa Solidago subsect. Triplinerviae showed that plants growing on the territory of the Republic of Belarus cannot be unambiguously assigned to any of the North American species by the combination of morphological characters. Compared to North American taxa, the plants of the studied populations have a significantly more powerful habitus (a large average plant height, longer and in many populations broader mid stem leaves, most often a larger inflorescence), intermediate in comparison with S. canadensis s. str. and S. altissima s. str. and significantly different from both North American species, the length of involucres and the length of tubular flowers, significantly longer outer phyllaries, shorter straps of ray florets, larger ovaries of ray florets, but their shorter pappus, a significantly smaller number of disc florets. The disc florets have significantly larger teeth compared to S. canadensis s. str. and S. altissima s. str. The data obtained confirm the point of view of Hildemar Scholz, according to which the invasive goldenrod, which is currently widely distributed throughout Europe, are of European origin. Most likely, they are either stabilized hybrids that arose during breeding due to the crossing of several North American species, or arose as a result of spontaneous mutation and further selection under natural conditions.","PeriodicalId":437681,"journal":{"name":"Journal of the Belarusian State University.

The experiments were performed on 48 Wistar male rats at 3 and 15 months of age. Experi mental animals, in addition to the standard diet, received magnesium chloride daily for 21 days at a dose of 50 mg / kg of body weight. Histological preparations were made from the liver tissue according to the standard method. The liver morphometry was performed on digital images using the computer program Image J. The content of magnesium cations was determined in the serum and suspension of red blood cells. Based on the results of our studies, it can be assumed that the administration of magnesium chloride activates the processes of physiological regeneration and functional activity of the liver parenchyma in rats of different ages. This is evidenced by an increase in the number of binuclear cells and nucleolus in the nucleus of hepatocytes, an increase in the nuclear-cytoplasmic and nucleolar-nuclear ratio. The relative area of the sinusoid network, the number and density of connective tissue cells were increased in the liver of 3-month-old experimental rats. This may indicate an increase of trophic and protective activity of the stroma in this organ. Experimental rats (15-month-old animals) revealed a moderate increasing in the erythrocyte suspension and blood serum magnesium content. The administration of magnesium chloride has the morphological features indicating an increasing of the physiological regeneration and activity of the liver parenchyma in young (to a greater extent) and adult animals.","PeriodicalId":437681,"journal":{"name":"Journal of the Belarusian State University.
