Growing melon under temperate climate conditions is quite risky due to the high climatic requirements of this species. Vegetable growers use plastic film mulches to heat soil, to reduce weed infestation, and to maintain optimal soil moisture content. The aim of our study was to determine the suitability of white and black plastic film for soil mulching in melon cultivation under temperate climate...
The pericarp of common bean Phaseoli Pericarpium syn. Fructus Phaseoli sine semine, is a medicinal raw material that has been long used in traditional folk medicine as an antidiabetic drug and now it is a pharmacopoeial material that belongs to one of the most frequently used plant raw materials that support treatment of diabetes. The aim of this study was to characterize the morphological characteristics...
The influence of leaf blanching with black polyethylene non-woven (PP) or white and black polypropylene foil (PE) used as soil mulching and blanching of leaves on yield, usefulness and biological value of cardoon leaf petioles were evaluated in the presented work. The effect of blanching duration of petioles (30, 25 and 10 days before leaves’ harvest) on the content of bioactive compounds was also...
The cultivation system with cover crops as living mulches is growing in importance in the worldwide agriculture as it combines an economical effect with pro-ecological and soil protecting activities. The plant species tested in the research were not frost resistant: buckwheat, millet, white mustard and berseem clover. A control were the plots without cover crops. The intercrops were sown in the first...
The purpose of this study was to compare the reading speed, phonological decoding, and comprehension between a group of children with anisometropic amblyopia (amblyopic group) (N = 21) and a group without visual problems (control group) (N = 37). Mean (± SD) age in amblyopic group was 10.3 ± 1.7 and 10.7 ± 1.3 years in control group (p = 0.130). The reading speed measurement was conducted with the...
Sweet pepper is an important vegetable plant, not only because of its economic importance, but also for the nutritional value of its fruits, mainly due to the fact that they are an excellent source of natural colours, especially carotenoids, antioxidant compounds and sugars. Saccharides content in the pepper fruits is the most important component of sweet taste of these fruits. In the available literature...
Capsaicinoids are secondary metabolites characteristic of plants of the genus Capsicum and are only found in the pepper fruit. Their biosynthesis occurs mainly in the placental cells as well as in the interlocular septa of the fruit. In the present study, the content of capsaicinoids (capsaicin and dihydrocapsaicin) was determined by HPLC in two hot pepper cultivars (‘Orkan’ and ‘Bronowicka Ostra’),...
Sweet pepper belongs to vegetables with high biological value, characteristic taste and health-promoting features, which depend on the content of many elements with antioxidant capacity. Pepper fruits are an important source of mineral components for people. The aim of this study was to determine the effect of different foliar feeding regimes with the use of calcium on the content of macro- and microelements...
Due to the unique taste features and pro-health values of fruits, hot pepper is cultivated in Poland on the commercial scale, most frequently with the use of single harvest which results in fruits at various maturity stage: green fruits, fruits turning colour and physiologically mature fruits (red). This paper, based on the results of 3-year experiments, evaluates utility and biological value of fruits...
The influence of vegetation period length of cardoon plants (Cynara cardunculus L.) on herb yield and its pharmacological value conditioned by chemical contents in air dried herb was examined in the research. The research conducted in the years 2009–2011 included valuation of total phenolic acids as equivalent to caffeic acid, flavonoids and tannins content in plants during their vegetative growth...
Luteina, zeaksantyna i β-karoten są związkami o właściwościach prozdrowotnych. Przedmiotem badań była ocena wybranych odmian dyni Cucurbita maxima D: ‘Amazonki’, ‘Justynki’, ‘Ambar’ i ‘Otylii F1’ pod względem zawartości wymienionych karotenoidów w próbkach liofilizowanych. Zawartość karotenoidów analizowano z wykorzystaniem HPLC-DAD. Stwierdzono, że liofilizowane owoce badanych odmian dyni są dobrym...
Consumer attractiveness and the usefulness for food processing of sweet pepper are determined by fruits quality values. The large weight, thick pericarp and intensive color at physiological ripeness as well as the share of pericarp to the fruit weight are most important. Such sweet pepper cultivars are now available in Poland. These cultivars are adopted to growing in less favourable environmental...
Broad bean seeds, with a high nutritional value at green maturity stage, are used for direct human consumption and in food processing. However broad bean green seeds had as a very shortly time to use because the green seeds very quickly lost the white-green fresh colour. The aim of the study was to evaluate the content of biologically active substances in fresh broad bean seeds immediately after the...
