Methods. A total 90 outpatients 55 intpatients swabs were cultivated....

High-performance thin-layer chromatography (HPTLC) combined with image analysis and pattern recognition methods were used for fingerprinting of phenolic compounds present in seedlings two maize genotypes ZP 434 (new generation hybrid, drought tolerant) 704 (older sensitive) treated different concentrations 24-epibrassinolide. This is the first report TLC chromatographic profile phenolics’ mixtures seed extracts influenced by brassinosteroid phytohormones. Nine samples shoot whole...

Deficiencies of mineral elements in human nutrition could be surpassed by crop fortification. One the prevalent measures fortification is foliar fertilization. The aim this study was to determine content and availability nutrients Mg, Fe Zn, together with phytate, as an anti-nutritive factor, β-carotene a promoter nutrient grain two soybean cultivars (Nena Laura) treated different non-standard fertilizers (mainly based on plant extracts). Generally, negative correlation between phytate...

Chemical composition of soybean grain may be modified by application foliar fertilizers. The aim this study was to test the effect different organo-mineral fertilizers: Zlatno inje, Bioplant Flora, Algaren BZn, Zircon, as well plant growth regulator Epin Extra, on potential availability mineral elements (Mg, Fe, Mn and Zn) from three commercial varieties: ZP-015, Nena Laura (variety lacking in Kunitz trypsin inhibitor). In addition, phytate (Phy) β-carotene contents were determined. ZP-015...

24-epibrassinolide (24-EBL) is plant steroid hormone that can regulate several physiological effects in plants, including promotion of cell growth and induction heat stress tolerance. The purpose this work to investigate the influence various concentrations 24-EBL on dehydration mechanism seedlings two maize hybrids (ZP434 ZP704). Control treated samples were subjected isothermal conditions for processes. carbohydrates mineral contents possible changes (from kinetics standpoint)...

Polyphenols present in different plant cell organelles increase the resistance of plants to various types environmental stresses. We investigated possibility increasing content bioactive compounds seed yellow soybean variety Laura. The was treated during vegetation with five products based on extracts, assumption enrichment nutrients. Soybean flour extracts were screened spectrophotometrically for total phenolic and antioxidant activity. activity evaluated using three methods. acids...

Brassinosteroids (BRs) are a class of plant hormones that play important roles in regulating various physiological and developmental processes plants. One the most effective BRs involved modulating crop growth is 24-epibrassinolide (24-EBL). The effects different concentrations 24-EBL on biochemical biophysical parameters critical to early stages seedling development were investigated using two maize hybrids, ‘ZP 434’ (a new-generation hybrid) 704’ (an older-generation hybrid). evaluation...

Proposed distributed reactivity model of dehydration for seedling parts two various maize hybrids (ZP434, ZP704) was established. Dehydration stresses were induced thermally, which is also accompanied by response to heat stress. It found that an increased value activation energy counterparts within radicle ZP434, with a high concentration 24-epibrassinolide (24-EBL) at elevated operating temperatures, probably causes diffusion mechanisms in cutin network and may increases likelihood...

Due to the frequent use of fossil fuels, which has negative effects on environment, there is a need find new, environmentally acceptable replacements for fuels. One possible replacement inclusion green technologies, in order obtain type fuel that would be from an environmental and economic point view. Biodiesel represents renewable less toxic substituent consists esters higher fatty acids depending conditions, can manufactured various types oils, both plant animal origin. Since corn one most...

Hexavalent chromium, Cr(VI), one of the major pollutants from industrial facilities, is very toxic and harmful for human health environmental quality. Due to lack conventional methods, bioremediation was recommended as an environmentally friendly effective technique. The aim this paper isolation, identification selection microorganisms which are capable Cr(VI) reduction in vitro. Heavy metal concentration, detected four soil samples, within around former bicycle factory ?Rog? (Republic...

One way of fast and effective impact on yield, pomological biochemical properties apple fruits is foliar fertilization. Thus, the fruit efficiently recharge poorly mobile secondary micronutrients, so plant protects against environmental stress in sensitive developmental stages. The last hypothesis we checked during second part growing seasons 2014, which were characteristic abundant precipitation first season. experiment was set 19th May 18 years old (Malus domestica L. cv. 'Idared') orchard...
