Aims. The trustworthy selection of transgenic plants essentially makes fast the whole transformation of procedure. The optimization of mass screening of corn and sunflower plants, obtained after Agrobacterium – mediated transformation in planta was created. Methods. Agrobacterium – mediated transformation with pBi2E suppressor of proline dehydrogenase gene was carried out. T0 corn and sunflower plants were tested under stress pressure. Lethal water stress in vitro was simulated by the addition of mannitol. The levels of free proline were measured. Results. The transgenic forms survived under lethal water stress. The free proline levels increased in plant tissues in various manners. The free proline contents maintained the tolerance and viability of transformed plants. Conclusions. The reliable method of the detection of plants, resistant to water stress there were proposed. 2015-01-01T00:00:00Z http://dspace.nbuv.gov.ua:80/handle/123456789/177429 Ростові процеси у стеблі озимої пшениці за різного забезпечення мінеральним живленням Жук, О.І. Aims. The aim of this work was to study the influence of mineral nutrition on stem tissue growth and winter wheat plants productivity. Methods. Winter wheat (Triticum aestivum L.) cultivars ‘Mironivska 808’ and ‘Favoritka’ were grown on mixture of soil and sand in pots with capacity of 7.5 kg. Optimal plant mineral nutrition was N₉₀P₉₀K₉₀ , deficit supply was N₃₂P₃₂K₃₂. During vegetation period the length of stem and fourth and fifth internodes of winter wheat plants were measured. After maturing the internodes and ears length, quantity of grains in ear, and mass of 1000 grains were measured. Results were statistically analyzed with Microsoft Excel. Results. The growth of winter wheat internodes and stem was studied under optimal and deficit support of mineral nutrition main elements — nitrogen, phosphor and potassium. The most intensive growth of wheat was detected in booting phase but under the optimal nutrition it was continued to milky ripeness phase. Under mineral nutrition deficit internodes growth stopped in earing-flowering phase. The smallest internodes were formed in in wheat cv. ‘Favoritka’. Conclusions. It was shown that decreased supply of winter wheat plants of cultivars ‘Mironivska 808’ and ‘Favoritka’ by nitrogen, phosphorus and potassium during pot experiment inhibited growth stem, internodes and productivity of plants. 2015-01-01T00:00:00Z http://dspace.nbuv.gov.ua:80/handle/123456789/177427 І. І. Мечников: життя і наукова діяльність. До 170-річчя від дня народження Чень, І.Б.; Гуменюк, Г.Б. The article focuses on the life, scientific and creative work of the outstanding scholar I. I. Mechnikov who was born and grew up in Ukraine. It highlights his main achievements and discoveries such as substantiation of intracellular digestion, formulation of phagocytic theory of immunity, identification of the essence of inflammation, doctrine of antibiotics, development of the concept of longevity. The contribution of his works to the development of zoology, embryology, microbiology, immunology, gerontology is revealed. His fundamental scientific works are examined. 2015-01-01T00:00:00Z
