The aim of this study was to determine dehydrogenases activity in the soil with the addition of NaCl in different concentrations and to identify whether the observed changes to be considered dangerous, tolerated, or insignificant for soil ecosystem. The study was carried out on samples of loamy sand, sandy loam and sandy clay loam. The aqueous NaCl solutions were introduced to soil in the doses of:...
An article presents results of six-month research (V–X 2012) of mineral nitrogen and phosphorus compounds on surface waters in Swidwie lake’s catchment area. In investigated water courses the concentration of nitrate nitrogen(V) classified water to I purity class and concentration of ammonium nitrogen classified most of these water-courses to II purity class. Whereas the concentration of the phosphate...
There is lack of work in which correlation between chosen qualitative features of sunflower seeds and settled of the fungi colonies have been investigated. The study was aimed to evaluate selective qualitative characteristics of sunflower seeds, to determine the quantitative analysis of fungi including different media and temperature incubation and to specify the correlation between sunflower seed's...
The aim of this study was to characterize the occurrence of Calamagrostis epigejos in communities in different biotopes (industrial waste clarifiers, sand and gravel pits, abandoned airports and military training grounds, urban areas, roadside, long-term fallow land, forest roads and parking lots near forests) in the western part of Western Pomerania and Lubin Upland (Gilów clarifier). This paper...
The ‘pontin’ translocation was obtained as a result of the recombination of segment from Thinopyrum ponticum with Lr19 gene, carrying resistance to leaf rust caused by Puccinia triticina, with chromosome segment of Thinopyrum intermedium, that contains Bdv2 gene that determines tolerance to Barley Yellow Dwarf Virus. Translocation ‘pontin’ is attractive for improvement of modern cultivars of common...
Subject of research presented in this paper was to evaluate the effect of depositing waste from the production of coke oven gas in the soil microorganisms inhabiting it, especially those with potential properties for biodegradation of hydrocarbons present in the waste. The number of microorganisms was evaluated according to MPN method (Most Probable Number) using microtiter plates. In the samples...
The aim of study was estimated of qualitative and quantitative composition of fungi in rapeseed on RBA, YpSs, DG18 medium at 25, 37, 45ºC. Material was 18 samples of rapeseed. The most amount of fungi were isolated on RBA at 25ºC (28), next xerophilic species (23) on DG 18 at 25oC and mesophilic (19) and thermophilic species (8) on YpSs medium at 37º and 45ºC, respectively. The predominant species...
The occurrence of underestimation of bone mineral density (BMD) and significant deficiencies of calcium and vitamin D in the diets examined male and female students. Proper BMD was significantly more common in people with excess body weight and consuming calcium and vitamin D nutritional guidelines at the level compared with students and deficiency of body weight and understated supply of calcium...
Eurotium herbariorum (Weber ex F.H. Wigg.) Link strains isolated from rapeseed, soybean and sunflower seed were incubated on liquid medium with oils, adequately, rapeseed oil, soybean oil and sunflower oil. Influence of water activity (aw) of medium (0.995; 0.950; 0.900 and 0.850) and temperature (15º and 25ºC) on dry mass, proteins content and lipolytic activity were studied. Irregardless of oil...
Avena sativa is an important breeding species in Poland which is due to the presence of proteins, soluble fibers, fat, minerals and vitamins. Nevertheless, the development of breeding programs of Avena is limited to low within species genetic variability. Thus, marker technologies capable of identification of many polymorphic markers is required to ensure further breeding progress. The current study...
Aim of the experiment carried out in 2008–2009 was to assess the effect of the kind of twin scales and seaweed extracts on yield of adventitious bulbs of Arabian Star Flower (Ornithogalum arabicum L.). The twin scales were excised from the outer and inner of the parent bulb. The twin scales were soaked for 30 minutes in 0.2% solution of AlgaminoPlant and Goëmar Goteo containing extracts of algae Ascophyllum...
Crown rust is a commonly occurring fungal disease of oat caused by Puccicnia coronata Cda. F.sp. avenae P. Syd. & Syd. Oat crop loss caused by this pathogen ranged to 50%. The most effective, economical and environmentally friendly method for controlling crown rust is growing resistant cultivars. The aim of presented study was characteristic of polish oat cultivars. Objectives of presented study...
It was studied the yield of post-harvest green manure on crop efficacy as a source of mineral nutrition of the following crops and gross dry matter content and basic nutrients in it in the Forrest-Steppe zone of Ukraine. It was found that the greatest increase in green mass of green manure, depending on moisture conditions of post-harvest period was 16–23 t . ha–1.
The study was aimed at comparing selected physical microclimate parameters in cowsheds with different keeping systems. The experimental material was constituted by four cowsheds (A, B, C and D) located in the Masovian Voivodeship. Cowsheds A and B contained similar numbers of cows (A – 24 heads, B – 26 heads). The cows in these sheds were kept using the stanchion system. Cowsheds C and D contained...
The aim of this study was to analyze the impact of the level of milk productivity on the length of interpregnancy period in a herd of cows of Polish Holstein-Friesian breed black-andwhite breed (phf cb). Three divisions of milk productivity in cows herd has been adopted: less than 6.000 kg per lactation of 305 day, from 6.000–9.000 kg and more than 9.000 kg of milk. In the present herd of cattle it...
The current study presents an analysis of selected hematological and biochemical parameters of the blood plasma of calves during the first month of life, before and after administration of a milk replacer with additional quantity of lactose. The experiment was performed on 8 male Polish-Friesan calves var. Black-and-White. Blood samples were collected before the morning feeding from 6th to 8th, from...
An increase in ecological food is observed in Poland. Produce obtained from ecological farms is perceived as healthier and richer in bioactive substances. The study defines the influence of cultivation methods of high-bush blueberry, ‘Duke’ cultivar (conventional and ecological) on the yield quality; size of fruits, their firmness and chemical composition. The study was performed in the years 2009–2011...
The experiment was carried out on 10 clinically healthy, female Polish-Friesian var. Black-and-White calves, during the first seven days of postnatal life. The aim of this study was to analyze renal regulation of chloride balance in calves during the first seven days of life. The mean blood plasma chloride concentration during the first week of calves’ life was 98.86 mmol · l–1 and was within the...
The objective of the study was to identify QTLs for the chlorophyll content (Chc) and the maximum photochemical activity of PSII (Fv/Fm) in rye. RIL population of DS2 × RXL10 hybrid cross consisting of 70 individuals of F7 generation constituted as experimental material. The obtained results were subjected to statistical analysis, and significant differences in the diversity of both traits in parental...
