Opis:: Spinosad is an insecticide with a completely unique and novel mode of action. It is used in a great variety of crops: fruit, vegetables, and ornamental plants. Its dissipation was studied in three vegetables: cabbage (the cultivar Stonehead), carrot (cv. Perfekcja) and onion (cv. Wolska). The vegetables were sprayed with a dose of 96 g a.i. ha-1 of spinosad and collected after 1, 3, 5, and 7 days. The residues were analyzed using high-performance liquid chromatography (HPLC) with ultraviolet (UV) detection after purification on a column with methanol. Elements were determined with flame atomic absorption spectroscopy (FAAS), and the determinations were made on the 1st and 7th day after spraying. The determined amounts of spinosad were in the range of 0.943-0.072 mg kg-1 for carrot and onion, respectively, on the 7th day. Spinosad decomposed completely in cabbage, and the highest level of the pesticide after 7 days remained in carrot, although the shape of all decomposition curves is quite similar. Most elements in onion were on significantly higher levels after sprays than in the control variant, opposite to cabbage, where higher levels of the analyzed elements were determined in the control. Concentrations of the elements determined in carrot were statistically significant for manganese, iron and magnesium. The spinosad decomposition time and the content of elements depend on the species of vegetables. The amount of spinosad on day 7 found in onion and cabbage was equal to the Maximum Residue Level (MRL) available in the literature.

Opis:: Tree saps were once commonly used in the countries of Northern, Central and Eastern Europe. Although once almost forgotten, their popularity has been growing recently as part of an interest in organic food and traditional medicine. Tree saps, tapped mainly from birch and maple trees, are drunk both fresh and fermented or are used as raw material for the production of food products, e.g. syrups. The aim of this study was to determine the content of inorganic anions in tree saps, as this parameter is often associated with toxicity of plant products. We measured the content of chlorides, nitrates and sulphates in the saps of six tree species with high pressure ion chromatography with the conductometric detection method. We detected the presence of chlorides, nitrates and sulphates in the studied tree saps. The highest concentration of nitrates was in the saps tapped from Norway maple (65.578 mg dm-3) and boxelder (108.313 mg dm-3). On the other hand, the highest concentration of sulphates was detected in the white willow tree saps (112.512 and 35.389 mg dm-3), while the one of chlorides, in the hornbeam tree sap (47.257 mg dm-3) and the Norway maple tree sap (41.143 mg dm-3). The detected content of chlorides, sulphates and nitrates in the tree saps under study does not reach toxic levels. Therefore we conclude that tree saps do not pose any health threat to consumers regarding their content of inorganic ions. Additionally, we observed a high intra- and interspecies variability in the concentration of inorganic anions in saps. This observation should be taken into account while designing any quality monitoring protocol regarding tree saps.

Opis:: Tree sap has been used for centuries not only as a source of nutrients available in early spring but also as medicinal substance in folk medicine. Traditionally, it was used to treat various conditions, mostly anaemia and chronic fatigue. This study has been designed to establish the content of metallic elements (sodium, potassium, calcium, magnesium, zinc and copper) in sap collected from eight different species (silver birch, downy birch, hornbeam, Norway maple, boxelder maple, black walnut, black alder and white willow) and to identify which sap has mineral content which would be most beneficial for human health. We measured concentrations of calcium, magnesium, sodium, potassium and zinc on an atomic absorption spectrometer equipped with single-element, hollow cathode lamps and an air/acetylene burner. The content of copper was determined using an atomic absorption spectrometer with Zeeman correction equipped with an electrothermal atomizer and argon as inert gas. White willow sap was determined to have the highest concentrations of magnesium, zinc, calcium and potassium. Moreover, this sap contained the lowest concentration of sodium among all the tree species. The sap with the lowest detected concentration of the metallic elements originated from black alder and boxelder. In conclusion, tree sap can be a valuable source of metallic elements, namely copper, zinc and magnesium, in human diet. Tree sap tapped from white willow is the most valuable in terms of its mineral content. Moreover, the most popular sap of sliver birch has proven to be a rich source of magnesium and zinc

Opis:: Competitive interactions are common in plant communities, but the underlying mechanisms and effects of competition have not been fully elucidated to date. A pot experiment (3 series in 2009-2011) was conducted to evaluate the effect of a sowing method of spring barley and Italian ryegrass, and different water condition on the nitrogen (N) content and accumulation in the aerial biomass of plants at different stages. The experimental factors were as follows: 1) sowing regime – pure sowing and mixed sowing – spring barley undersown with Italian ryegrass, 2) water supply – plants supplied with water to meet their full requirements and 50% water supply reduction. The N content of the aerial biomass of plants was determined at five phenological development stages of spring barley grown in a pure stand under optimal soil moisture conditions: leaf development, tillering, stem elongation, heading and ripening. Nitrogen uptake was determined based on the N content and dry matter accumulation in plants. Nitrogen concentrations in the aerial biomass of barley and ryegrass varied throughout the growing season. Nitrogen content was particularly high in leaves, and it decreased steadily during plant development. Neither the sowing regime nor the water supply exerted significant effects on the N content of the aerial biomass of spring barley. In Italian ryegrass, under optimal water supply, mixed sowing with spring barley decreased N concentrations in shoots only during tillering. In spring barley, mixed sowing reduced N uptake by biomass, and the observed decrease was exacerbated under water deficit. In Italian ryegrass, reduced water supply decreased N uptake, but the effect of competitive interactions between the analyzed species was usually stronger than the influence of water deficit. Differences in N accumulation in aerial biomass were determined by the amount of biomass produced in mixed stands and the responses of barley and ryegrass to water deficit.

Opis:: In this research, the response of the plant Gypsophila arrostii Guss. to boron (B) under in vitro conditions was examined. The seeds were cultured on MS medium including 0, 10, 20, 40, 80 mg B l-1. Seedlings obtained from germinated seeds and grown in a culture medium for 8 weeks were analyzed. At the end of this period, stem length (cm), root length (cm), plant weight (g) and elemental content (mg kg-1) of the plants were determined. According to the results, the seeds of G. arrostii Guss. could germinate on media with up to 80 mg B l-1, and the seedlings demonstrated an ability to survive, albeit poorly, a dose of boron as high as 80 mg B l-1. In the experiment, the highest stem length (7.5 cm) was obtained from the 20 mg B l-1 treatment and the highest stem fresh weight (0.9 g) and stem dry weight (0.19 g) were measured in the 10 mg B l-1 variant. No significant statistical difference was determined between the boron treatments in terms of root length, root fresh weight and root dry weight. Our evaluation of the elemental content of plants demonstrated that the amount of boron in the root and stem increased parallel to its increase in the growth media. In the 80 mg B l-1 treatment, 601.9 mg kg-1 boron in root and 1,035.4 mg kg-1 boron in stem were determined. Besides, it was discovered that the contents of K, Mg, Zn, Na in root decreased while the contents of P, B, Mn, Cu in root increased in response to the growing amount of boron in the environment. In response to the increasing boron concentrations, the content of K, P, Mn, Cu, Zn and S increased while the amount of Ca, Mg and Na in the plant stem decreased. Consequently, G. arrostii Guss. was found to be a boron hyperaccumulator, collecting boron in tissues (in the roots and stems), in which it resembled some other types of Gypsophilla.

Opis:: Water soldier is a plant growing all across lowlands in Poland, in eutrophic reservoirs of still and slowly flowing water. Because this macrophyte is used as a fertilizer or a component in fodder for cattle or pigs, the purpose of this paper was to determine the content of magnesium and calcium in water soldier depending on pollution of water with selected heavy metals. The study used water and plant samples collected from the natural environment and a hydroponic experiment (6 variants of water pollution with heavy metals and two terms of plants’ exposure). Concentrations of magnesium and calcium in the mineralized samples were measured in three cycles with the atomic absorption spectrometry method on a spectrometer Solaar S AA. Water soldiers (from the hydroponic experiment) contained 5.911 g Mg kg–1 d.w. and 16.32 g Ca kg–1 d.w. It was determined that both addition of a heavy metal and the exposure time had a statistically significant effect on concentrations of magnesium and calcium in water soldier, as well as on their concentration in water. Except the control and regardless the exposure time, most magnesium remained in those water soldier specimens that had been exposed to iron and cadmium. The smallest amounts of magnesium in a plant were observed when water had been enriched with ions of zinc and cooper. After 6 weeks of exposing the plants to the metals, the content of magnesium was 12% lower than after 3 weeks. On the other hand, the smallest amount of calcium in water soldier was recorded for specimens exposed to iron and cadmium, while the largest amount was found in those grown with an addition of zinc and in the control group. The drop in calcium content measured on the second term, compared to the first one, was 6.119 g kg–1 d.w. Pollution of water with heavy metals has a negative effect on development of water soldier and on accumulation of calcium and magnesium. The reduced content of calcium and magnesium in plants collected from waters polluted with heavy metals will affect the value of water soldier both as a fertilizer and a fodder additive.
Osoka aloesowata występuje na całym niżu na terenie Polski w zeutrofizowanych zbiornikach wód stojących i powoli płynących. Ze względu na stosowanie tego makrofitu do użyźniania gleb i jako komponentu pasz dla bydła i świń celem pracy było określenie zawartości magnezu i wapnia w osoce aloesowatej w zależności od zanieczyszczenia wód wybranymi metalami ciężkimi. W badaniach wykorzystano próbki wód i roślin pobrane ze środowiska naturalnego i z doświadczenia hydroponicznego (6 wariantów skażania wód i 2 czasy ekspozycji roślin na działanie jonów metali ciężkich). Pomiary zawartości magnezu i wapnia w zmineralizowanych próbkach wykonano techniką ASA w 3 powtórzeniach. Wykorzystana w doświadczeniu hydroponicznym osoka aloesowata zawierała 5,911 g Mg kg–1 s.m. i 16,32 g Ca kg–1 s.m. Na podstawie analizy statystycznej ustalono, że zarówno dodatek metalu ciężkiego, jak i czas ekspozycji miały istotny statystycznie wpływ na zawartość Mg i Ca w osoce aloesowatej i stężenie tych pierwiastków w wodzie. Najwięcej Mg, poza kontrolą, niezależnie od czasu ekspozycji, pozostało w osobnikach osoki aloesowatej poddanych działaniu Fe i Cd. Najmniejsze ilości Mg w roślinie stwierdzono po dodatku do wody jonów Zn i Cu. Po 6 tygodniach ekspozycji roślin na działanie metali zawartość Mg była o 12% mniejsza niż po 3 tygodniach. Najmniejszą zawartość Ca w osoce aloesowatej zanotowano u osobników poddanych działaniu Fe i Cd, a największą po dodatku Zn i w kontroli. Spadek zawartości Ca w II terminie w stosunku do I wyniósł 6,119 g kg–1 s.m. Zanieczyszczenie wód metalami ciężkimi ma niekorzystny wpływ na rozwój osoki aloesowatej oraz kumulację Ca i Mg. Zmniejszona zawartość Ca i Mg w roślinach pobranych z zanieczyszczonych metalami ciężkimi wód obniży wartość zarówno uzyskanego nawozu, jak i dodatku paszowego.
