Three sites with both degraded alpine Kobresia meadow (DM) and adjacent mix-seeded perennial grasses pastures (MSP) in the headwater region of the Yellow River, Qinghai-Tibetan Plateau, were selected to investigate plant and soil organic carbon (SOC), total nitrogen (TN) and their isotope composition. The SOC and TN in the top soil layer to a depth of 10 cm were significantly affected by ploughing...
The time within which, accordingly to its application, machine works, and an object of work and working groups are under load, is the effective active time. The purpose of the research was the order statistics of effective active time of limbing and conversion at chainsaw use. The removed trees were moderately diversified from the point of view of effective active time of limbing and conversion. The...
Angiotensin (Ang) (1-9) is the renin-angiotensin-system peptide found in the plasma of healthy volunteers and after angiotensin-converting-enzyme inhibitors therapy. In vitro experiments proved that Ang-(1-9) may be produced from Ang I. In our study, we tried to expand the poor data about the in vivo properties of Ang-(1-9). We revealed that Ang-(1-9) enhanced electrically stimulated arterial thrombosis...
The study shows a high dynamics approximately five-year-old natural regeneration of silver birch (Betula pendula Roth) growing on the research plot located in the fertile mountain habitat in the middle of the lower montane forest zone in the Silesian Beskid Mountains (Beskid Śląski) compared to its co-occurring species. The dynamics is expressed as a significant annual increment in height and diameter...
This is the first report of somatic embryogenesis from leaves of two strawberry cultivars (Selva and Comarosa) cultured on MS medium containing picloram. Maximum embryogenesis was induced using 2 mg/l picloram. Globular stage embryos developed into cotyledonary ones after transfer to hormone-free media containing 2%, 4%, 6%, 8% and 10% (w/v) sucrose. Increasing sucrose concentrations in culture media...
Starch liquefaction without significant increase in dextrose value was attempted. Potato, corn and pea high amylose starches were digested with thermostable alpha-amylase. Different reaction conditions (starch concentration, enzyme dosage, time reaction) were used in hydrolyses into DE < 10. Chemical and physical properties of obtained hydrolysates such as carbohydrate composition, iodine absorbance...
