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:: 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:: 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:: Copper is an essential trace element in living organisms, but its excess interferes with metabolic transformations in plant, animal and human cells. The uptake of copper from contaminated soils can be regulated, for example, by soil liming or application of other substances which enhance soil adsorption capacity and Cu binding in the substrate. The purpose of this study has been to assess the response of maize to soil contamination with copper depending on the applied neutralizing substances. The tested factors were increasing concentrations of Cu in soil: 0, 200, 400 and 600 mg Cu kg ?1 dm, and soil application of mineral (lime, loam and zeolite) and organic (manure, peat and bark) neutralizing substances. Soil contamination with copper within the range of 200 to 600 mg kg ?1 of soil caused reduction in maize yields. Positive influence such as alleviation of the harmful effect of copper contamination was demonstrated by lime and manure, which enhanced yields of maize, especially in the series polluted with 200 and 400 mg Cu kg ?1 . The other soil amending substances, especially peat added in amounts of 400 and 600 mg kg ?1 of soil, caused aconsiderable depression in maize yields. A linear dependence has been demonstrated between the concentration of Cu in maize plants and the content of Cu in the substrate, with the root content of Cu being on average six-fold higher than in aerial organs. Mineral soil amendments significantly decreased the BTC index in maize compared to organic substances, and lime as well as pine bark decreased the BCF index to 2.33 and 1.67 versus the value of 4.21 found in the control treatment without any neutralizing substances. The uptake of copper depended on the volume of yield and ? to a lesser degree ? on the concentration of Cu in plants. The uptake of copper by plants was the highest in treatmentscontaminated with a rate of 200 mg Cu kg ?1 , which was the consequence of higher yields from that treatment than from the plots polluted with 400 or 600 mg Cu kg ?1 of soil.

Opis:: Zinc accumulation and the growth of Saccharomyces cerevisiae were investigated in a culture with zinc sulfate-supplemented medium. The cultivations were performed on Sabouraud dextrose broth medium in aerobic conditions, without the addition of zinc (control culture) and with the addition of zinc sulfate (5, 10, 15, 30 and 60 mg ZnSO l -1 medium) at 28 ° C for 72 hours. The results showed similar trends of yeast growth rates at 24, 48, and 72-hour interval, with concentrations above 10 mg l -1 ZnSO in the nutritional medium significantly decreasing the yeast growth rate and the biomass yield ( P <0.05). Substantial differences between the initial ZnSO concentrations in the growth medium were demonstrated in the overall adsorption of Zn ions (Zn 2+ ) in yeast cells by a colorimetric assay ( P <0.05). Similarly, the content of total accumulated zinc, as well as the fractions of Zn present in cells depended mainly on the zinc concentration in the medium, as the total Zn accumulation and organically bound Zn fractions were increased by elevating the ZnSO supplementation in the culture medium up to 30 mg l -1 , but gradually reduced by any further addition of ZnSO determined by an ICP-MASS assay ( P <0.05). In the presence of 30 mg l -1 ZnSO , the Zn content in the biomass increased by 24-fold, to 4132.34 m g g -1 in comparison to 171.9 m g g -1 achieved in the basal medium. Thus, the ability of S. cerevisiae to accumulate zinc can be used for production of a zinc-rich ingredient for functional food products.

Opis:: Wheat production is required to double by 2050 in order to facilitate the global food assurance. Along with the rise in wheat production, improvement of the nutrient value of wheat varieties is another crucial challenge faced by wheat breeders. It is well established that more than 40% people in the world are at a risk of malnutrition caused by the deficiency of Fe, Zn and protein in their food. Numerous strategies are adopted by scientists, breeders and food industries to combat the problem. In this context, biofortificaton has become a successful method for increasing, either genetically or agronomically, the micronutrient content in crop plants. Recently, substantial progress has been made in the use of molecular marker systems and quantitative trait loci (QTL) to augment the wheat iron, zinc and protein content. Determining the role of GPC-B1 gene in controlling the iron, zinc and protein content in wheat genotypes is a promising discoveries. Although the gene is found to be associated with an elevated micronutrient content, it is also responsible for a decrease in yield. In order to simultaneously achieve both high nutrient content and elevated yield, major efforts are required to reveal the genetic control of these traits. Moreover, identifying the wheat genomic resources with an elevated nutrient content can be crucial. Employment of the next generation sequencing methods and use of molecular markers in marker assisted selection appears to be a promising approach to attaining the objective of breeding nutrient rich varieties. Combining advanced molecular biology and plant breeding techniques for wheat development is a potential strategy in achieving a healthy, ‘hidden hunger’ free world.
