Opis:
Our objective was to determine the content of macro- and micronutrients, toxic heavy metals as well as total phenols in 10 broccoli (Brassica oleracea var. italica) cultivars. The experiment was designed at the Poznań University of Life Sciences, Poland, and completed during two plant growing seasons. Broccoli seedlings were planted in a field in early July and the plants were harvested between September and October. The content of general forms of nitrogen was measured by distillation with the Kjeldahl method. The content of potassium, calcium and sodium was assessed by flame photometry, and the content of magnesium, cadmium, lead, nickel, copper, zinc, manganese and iron was determined by flame atomic absorption spectroscopy (FAAS). The content of heavy metals, macronutrients and sodium in the broccoli heads depended on a cultivar. Having analyzed the levels of macronutrients in ten broccoli cultivars, it was concluded that cv. Agassi and Tradition had the highest content of nitrogen and phosphorus. A very high amount of phosphorus was also found in cv. Beaumont. The highest concentrations of calcium and potassium were found in cv. Monte Carlo. The cultivars Agassi, Beaumont, Tiburon and Tradition were characterized by the highest content of magnesium. The highest content of sodium occurred in the cultivars Beaumont and Monopoly. With respect to micronutrients, the highest content of iron, copper, zinc and manganese was revealed in cv. Agassi. The highest content of nickel was determined in the cultivars Beaumont and Monte Carlo. In addition, the cultivar Monte Carlo was characterized by the highest content of lead, and Beaumont had the highest content of cadmium. However, the maximum permissible levels of cadmium and lead were not exceeded in the heads of the ten broccoli cultivars. In both years of the study, the highest content of phenols was found in cv. Steel and the lowest one appeared in cv. Agassi.

Opis:
Temperature is a factor which strongly affects the yield and broccoli head quality. Temperature determines the date of head initiation and thus affect the length of vegetation period. An experiment the aim of which was to assess the impact of temperature on the yield and the length of the period from the broccoli head initiation until the beginning and end of harvest as well as the length of the harvest period was carried out in years 1997–1999. The seedlings of cv. Fiesta were planted in April, May, June and July. The phase of head initiation was determined on the basis of analyses of microscopic preparations. The highest total yield was obtained from May and June planting dates, the highest marketable yield was recorded in the case of the May date planting. A higher correlation was found between the sum of temperature and mean daily air temperature in the period from the initiation to the beginning and end of harvest and mean weight of marketable heads than between temperature and the total yield. The highest correlation was determined between the mean air temperature and the number of days from the head initiation to the last harvest.
Temperatura jest czynnikiem, który silnie wpływa na wielkość i jakość plonu brokuła. Determinuje również termin zainicjowania róży, wpływając przez to na długość okresu wegetacji. Doświadczenie, którego celem była ocena wpływu temperatury na wielkość plonu brokuła i długość okresu od zainicjowania róży do początku i końca zbiorów oraz długość okresu zbiorów, przeprowadzono w latach 1997–1999. W każdym roku prowadzenia doświadczenia rozsadę brokuła odmiany ‘Fiesta’ wysadzano w czterech terminach: kwiecień, maj, czerwiec i lipiec. Fazę inicjacji róży określono na podstawie analizy preparatów mikroskopowych. Największy plon ogólny uzyskano, gdy posadzono rośliny w maju i czerwcu, a największy plon handlowy przy sadzeniu roślin w maju. Stwierdzono wyższą zależność między sumą i średnią dobową temperaturą powietrza w okresie od inicjacji do początku i końca zbiorów, a średnią masą róży handlowej niż między temperaturą a wielkością plonu ogólnego. Najwyższą zależność stwierdzono między średnią dobową temperaturą powietrza, a liczbą dni od inicjacji do ostatniego zbioru.
