The morphological types of the pulmonary valve and its adjacent structures were determined. The research was conducted on the heart of 498 domestic and wild birds of five orders. The organ underwent imaging with the use of an X-ray apparatus, a 16- slice computed tomography scanner, and an ultrasonograph. The structures examined are characterised by a great changeability as far as particular taxonomie individuals are concerned. This is connected with the ways and living conditions of particular taxonomic and ecological groups of birds. New terms to characterise the pulmonary valve were suggested. Research of this type will allow us to link such basic sorts of study with cardiac surgery in the future.
In 2005-2007, in the field experiment, the yield and quality of summer savory herb of Polish cultivar Saturn in organic farming were tested. The experiment was established on six organic farms and one conventional farm in different localities in Poland. The following features were evaluated: fresh and dried herb yield, stem fraction in herb, seed yield, weight of 1000 seeds, essential oil content, macro- and microelement content, nitrate content and microbiological purity. Only from Słońsk savory herb yield was higher compared with the yield from conventional cultivation though it contained high amount of stems. Organic savory herb was characterized by high content of essential oil and increased content of macro- and microelements. Evaluation of microbiological purity showed that herb contamination from both types of cultivation did not exceed standard for raw materials treated with hot water.
In 2005-2007, in a field experiment, the yield and quality of the thyme herb of the Polish cultivar Słoneczko in organic farming were tested. The experiment was established on six different organic farms and one conventional farm in Poland. The following features were evaluated: fresh and dried herb yield, stem fraction in herb, essential oil content, and microbiological purity. Only from one organic farm in Słońsk thyme herb yield was higher compared with the yield from conventional cultivation, although it contained a high amount of stems. Organic thyme herb was characterized by a high content of essential oil. Evaluation of microbiological purity showed that herb contamination from both types of cultivation did not exceed the standard for raw materials treated with hot water.
In 2005-2007, in the field experiment, the yield and quality of sweet marjoram herb of Polish cultivar ‘Miraż’ in organic cultivation were tested. The experiment was established on six organic farms and one conventional farm in different localities in Poland. The following features were evaluated: fresh and dried herb yield, stem fraction in herb, seed yield, essential oil content, macro- and microelements content, nitrate content and microbiological purity. Organic marjoram herb yield only from one farm (Słońsk) was higher compared with the yield from conventional cultivation, though this herb contained high amount of stems. There were no seeds collected or the seed yield was very low in both organic and conventional farming. Both marjoram herbs, organic and conventional from Plewiska had similar quality (essential oil, macro- and microelements and nitrate content). Evaluation of microbiological purity showed that herb contamination from both types of cultivation did not exceed standard for raw materials treated with hot water.
In 2005-2007, in a field experiment, the yield and quality of the basil herb of the Polish cultivar Kasia in organic farming were tested. The experiment was established on six organic farms and one conventional farm in different location in Poland. The following features were evaluated: fresh and dried herb yield, stem fraction in herb, seed yield, weight of 1000 seeds, essential oil content, macro- and microelements content and microbiological purity. Only from one organic farm in Słońsk basil herb was yield higher compared with the yield from conventional cultivation, although it contained a high amount of stems. Organic basil herb was characterized by a high content of essential oil and an increased content of macro- and microelements. Evaluation of microbiological purity showed that herb contamination from both types of cultivation did not exceed the standard for raw materials treated with hot water.
