The purpose of studies was to determine chemical properties of composts and content of macro- and microelements of butterhead lettuce (Lactuca sativa L.), cultivar Królowa Majowych, from allotment gardens of West Pomeranian Voivodeship. Chemical analysis included pH, content of organic matter, organic carbon, total nitrogen and total sulphur as well as total amount of macro- and microelements. The...
The experimental material consisted of 52 805 ejaculates obtained from 335 boars. The ejaculates were collected using the gloved-hand technique. Each ejaculate was assessed using standard methods for the following physical traits: volume, sperm concentration, total number of spermatozoa, and number of insemination doses per ejaculate. The collected materials were grouped according to the criterion...
In 1998, three years after technical and biological reclamation, 29 relevés were made in the ridge area (the crown of the excavation) of the quarry “Piotrawin”. Two segetal associations were distinguished (Sileno inflatae-Linarietum minoris and Lathyro-Melandrietum noctiflori) as well as one xerothermic grassland association (Inuletum ensifoliae). The communities are floristically very rich. The number...
Described the border site of Ranunculetum fluitantis Allorge 1922 plant association in the Myśliborka stream documents the new location of "Lowland and foothill rivers with batrachion vegetation communities Ranunculion fluitantis (code – 3260)" in Western Pomerania and in the Natura 2000 site "Ostoja Wkrzańska" PLB 320014. In waters of the stream verified the presence of rare species...
Embryonic mortality is associated with full resorption of tissues and fluids from the uterine cavity. Foetal mortality usually results in complete or partial abortion. Sometimes, however, dead fetuses and foetal membranes retain in the uterus till term or even longer. There are only scant information in this area, without epidemiological studies. Each new case widens the knowledge of this condition...
The study was conducted in the years 2008–2011. Two factors were taken into account in the research: I – the amount of seeds sown: 9, 12 and 15 (kg · ha–1) and II – nitrogen dose: 0, 60, 90 and 120 kg · ha–1. The experiment was founded in the spring of 2008, with sowing with a nurse crop – spring barley, on brown soil of brown acidic subtype formed of light clayey sand of glacial origin – IVb soil...
During faunistic studies conducted in north-western Poland on the entomopathogenic nematodes (EPN) of the families Steinernematidae and Heterorhabditidae, species Steinernema silvaticum was identified for the first time in Poland. Nematode species identification, using morphometric methods, is laborious, even for an experienced researcher. S. silvaticum and S. kraussei are defined as “sister taxa”...
The aim of the study was to determine the changes of the acid and alkaline phosphatase activity in the soil caused by the presence of cadmium and NaCl. The experiment was carried out in the laboratory condition, on soil samples taken from the arable-humus horizon of Gumieniecka Plain black earths. Granulometric composition of this soil was sandy loam. The organic carbon content was 1.09%, total nitrogen...
Obszar Dolina Płoni i Jezioro Miedwie PLH 320006 jest jednym z najcenniejszych obiektów sieci Natura 2000 na Pomorzu Zachodnim. Został on ustanowiony w celu ochrony 17 typów siedlisk przyrodniczych, dwóch gatunków roślin i czterech gatunków zwierząt wymienionych w załączniku I i II dyrektywy siedliskowej. Celem niniejszej pracy było zaprezentowanie wartościowych taksonów flory naczyniowej tego obszaru...
The aim of the thesis was to acquaint oneself with the dendroflora of Gryfino. The research was carried out between 2009 and 2010 and in 2013. Out of 279 taxons specified to their as species and a variety, 5.0% are plants of European origin, 22.6% – plants occurring naturally in Europe and outside of Europe, 15.0% are plants of Asian origin, 11.8% – plants occurring naturally in North America, 4.7%...
