The research objective was to determine and compare dry matter, crude protein, mineral elements (total), dietary fiber, easily hydrolysable sugars, vitamin C, and minerals (K, Na, Mg, Cu) as well as the content of epicatechin and phenolic acids (homovanillic, chlorogenic, caffeic, coumaric, and ferulic) in the flesh and peel of ‘Šampion’ cv. apples grafted on 4 different rootstocks types: M.26, P2,...
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...
Wprowadzenie. Dla większości Polaków ziemniaki stanowią nieodzowny składnik codziennej diety. Gotowane w wodzie lub na parze, uważane są za pokarm odpowiadający wymogom właściwego żywienia, jednak obok składników odżywczych mogą zawierać związki niepożądane. Cel badań. Celem badań była ocena zawartości suchej masy i niektórych składników odżywczych (skrobia, witamina C) oraz potencjalnie szkodliwych...
Four field experiments were conducted to determine the effects of the use of plane (Titan, Karnaval, Festival, and Natalka) and curled-leaf cultivars (Paramount, Petra), the quality of transplants raised in different cell volumes (95, 69.3, 32.0, 25.6, 10.0 cm³), Jiffy pots - (112.5 cm³) and the number of plants per cell (1, 2, and 3), as well as plant cover in the field with perforated foil fleece,...
The nutritive value and wholesomeness of carrot are highly appreciated owing to such biologically active compounds as carotenoids, vitamin C and mineral compounds found in its roots. In 2007-2009, field experiments were performed on the effect of foliar fertilisation of carrot with magnesium sulphate during its vegetative growth on selected nutrients (total carotenoids, vitamin C, mineral magnesium)...
Within the Ocimum genus there occur about 200 species in different varieties and forms. They differ in the essential oil content and quality, as well as in many morphological features. The studies conducted in the years 2008–2009 were aimed at defining the effect of basil cultivar (‘Kasia’ and ‘Wala’), as well as of the differentiated doses of CaCO3 (6 or 12 g·dm-3 of substratum) upon the biological...
Fennel (Foeniculum vulgare var. azoricum Mill.), despite its high dietary value, is not a very popular vegetable in Poland. It bulbs constitute a low-calorie food, abundant in vitamins and mineral salts. They also contain, though in smaller amounts, the essential oil, determining the use of fennel fruit in medicine. In the field experiment with fennel growing the influence of soil mulching and flat...
The nutritional value of some vegetables may greatly vary depending on the cultivation method and kind of fertilization. In 2007–2009 there was conducted a field experiment to evaluate the effects of nitrogen fertilizers (ammonium nitrate, calcium nitrate, ammonium sulphate, urea, Entec-26) and their doses (80, 160 kgN∙ha-1) on yielding and biological quality of two spinach cultivars (Spokane F1,...
Endive, like another leafy vegetables, as an annual plant with short time vegetation is prone to nitrate accumulation. The aim of research conducted in the years 2007–2009 was the assessment of the effect of diversified nitrogen doses on growth, yielding and nutritive value of two ‘Excel’ and ‘Cigal’ –endive cultivars. There were compared the effects of two kinds of fertilizer: ammonium saltpeter...
W ścisłych doświadczeniach polowych, przeprowadzonych w dwu miejscowościach w Polsce, o różnym położeniu nad poziomem morza, w latach 2006-2008, stwierdzono wpływ odmian ziemniaka, o różnym zabarwieniu skórki i miąższu na plon, cechy morfologiczne i cechy składu chemicznego bulw. Wyższym plonem ogólnym i handlowym cechowały się odmiany o żółtym niż kolorowym miąższu. Wyższą zawartością suchej masy,...
Celem badań, przeprowadzonych w latach 2006-2008, było porównanie wartości odżywczej owoców ukraińskich i litewskich odmian porzeczki czarnej z odmianą szwedzką Titania w warunkach północno-wschodniej Polski. W jagodach badanych odmian porzeczki określono zawartość suchej masy, antocyjanów, kwasów organicznych, witaminy C oraz cukrów prostych i ogółem. Analiza statystyczna wyników wykazała wysoce...
Nowe odmiany borówki półwysokiej mogą być uprawiane w regionie północno-wschodniej Polski. Nie odnotowano przemarzania krzewów, młodych pędów i kwiatów podczas zimy i przymrozków wiosennych. Otrzymane wyniki wskazują, że najlepiej plonowała odmiana szwedzka Putte. Nie należy polecać do uprawy odmiany Northcountry ze względu na bardzo małe plony z krzewów. W naszych badaniach owoce odmiany Emil zawierały...
In precise field trials at five localities in the CR within years 2004-2005 the effects of different locality conditions and yellow- and purple- fleshed potato cultivars on ascorbic acid (AA) and total polyphenol (TP) contents in tubers were determined. AA content on average of nine cultivars reached the value 170.3 mg·kg⁻¹ FM and was demonstrably affected by the genotype of cultivar and locality...
In the usable parts of dill plants of cultivars Amat, Ambrozja, and Lukullus, grown in five cycles from spring to autumn, the level of vitamin C, carotenoids, beta-carotene, and polyphenols was determined. In the fresh leafy part of dill the content of the analysed components was significantly greater than in leaves with petioles. In the fresh matter of the leafy part the content of vitamin C varied...
W doświadczeniu polowym przeprowadzonym w RZD w Bałcynach w latach 1984-1986 badano wpływ trzech terminów sadzenia (20 IV, 5 V, 18 V) oraz nawożenia azotowego (50, 100, 150, 200 kg N/ha) na jakość bulw ziemniaka sześciu odmian Beryl, Dukat, Cisa, Mila, Bronka, San. Opóźnienie terminu sadzenia o 14 i 28 dni zmniejszyło zawartość suchej masy, odpowiednio o 0,6 i 0,9%, oraz plon suchej masy o 11 i 28%...
