Root-knot nematodes have become a grave menace to the lucrative production of cucumber throughout the world. These nematodes are mainly controlled by applying nematicides, but their use is often associated with hazards. Alternatively, the use of nematode resistant cultivars is considered to be innocuous and economically feasible. For their fitness as nematode-suppressive crops, the reduction in growth...
Celem badań była ocena dynamiki wzrostu oraz zawartość suchej masy i wybranych składników organicznych w cebuli zwyczajnej w okresie wzrostu. Doświadczenie polowe przeprowadzono w latach 2012-2013 w województwie kujawsko-pomorskim (53°6′50″N, 19°4′6″E). Materiał badawczy stanowiły rośliny czterech odmian cebuli zwyczajnej: Błońska, Dakota F1, Norvito F1, Octavia. Nasiona wysiewano w II dekadzie kwietnia...
Przedstawiono krótki przegląd występujących w owocach i warzywach, wywołujących uczulenia, profilin i białek zapasowych. Zwrócono uwagę na reakcje krzyżowe pomiędzy omawianymi alergenami a homologicznymi białkami obecnymi w pyłkach popularnych roślin. Na koniec omówiono kierunki badań, których celem jest poszukiwanie hipoalergicznych odmian owoców i warzyw.
This study, conducted in the period 2006-2008, involved an evaluation of yield and commercially useful traits of red cabbage grown from seedlings produced from seeds sown at three different times (the second decade of April, the third decade of April, and the first decade of May). Seedlings were produced in multicell trays in an unheated greenhouse and in a nursery bed from seeds sown at the same...
Foliar feeding of plants is an important supplementation of soil fertilization in vegetable cultivation. Foliar-fertilized plants deliver high yields of good quality at lower rates of mineral fertilization. In horticultural practice foliar fertilization is also recommended as the most effective method of supplying plants with nutrients under deficiency conditions. An experiment was established to...
The aim of an experiment conducted in 2006–2008 was to determine the effect of soil fertilization with Crop Care on the yield and chemical composition of carrot cultivars with orange- and purple-colored storage roots. The yield and chemical composition of three carrot cultivars: ‘Florida F1’ with orange-colored roots, ‘Deep Purple F1‘ with purple-colored roots and ‘Purple Haze F1‘ with roots that...
In recent years in Poland there has been an increasing interest in the field growing of sweet peepers, both among producers and consumers. Therefore, research should be conducted to select cultivars well adapted to less favorable temperature conditions and suitable for cultivation in the field, and to increase their yield. A field experiment was carried out in the years 2006–2008 in the Garden of...
Shallot is one of the vegetables, which are especially abounding in flavonoids, phenolic acids and other compounds with antioxidative properties. Among Allium vegetables it is also distinguished with good storage ability. The studies conducted in the years 2007–2009 included the assessment of dry matter, flavonoids and phenolic acid contents in shallot bulbs immediately after harvest and drying off,...
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,...
