    Abstract On a worldwide scale, A. cepa is among the most commonly consumed vegetables. In Europe, the leading onion producers are Russia, the Netherlands, Spain, Poland and Germany. In this study, the bioaccumulation of heavy metals (Cr, Cu, Zn, Ni, Fe, Mn, Co, Sr, Cd and Pb) by Allium cepa L. plants was followed under hydroponic conditions. The heavy metals were applied at six concentrations (0, 25, 50, 100, 200 and 400 mg L −1 ) over three weeks. The quantitative analysis of selected heavy metals in plant tissues (bulbs, roots and assimilation leaves) was performed using atomic absorption spectrometry with flame atomization (F-AAS). The accumulation of metal ions was strongly dependent on their concentrations in the solution and the analyzed parts of plants. The highest accumulation of metal ions was confirmed for the roots and ranged from 8.48 to 5912.34 µg g −1 DW (dry weight). All parts of A. cepa were characterized by the high accumulation of Mn 2+ . The lowest accumulation was confirmed for Co 2+ in the roots, Pb 2+ in the assimilation leaves and Cu 2+ in the bulbs of onion. Moreover, the study showed that the highest concentrations of heavy metals decreased the growth of bulbs and even caused them to die off. In contrast, lower concentrations of some elements stimulated plant development.

    Abstract In a two-factor field experiment, the stem and leaf characteristics and productivity of the ‘Flanders’ and ‘Barbara’ linseed cultivars were compared in four developmental stages in relation to the sowing method. The linseed grown in intercropping with pea, irrespective of the cultivar, was characterized by small leaves in the stem extension stage, but the leaf area significantly increased beginning with the budding phase. Comparison of the cultivars showed that the Barbara cultivar had significantly more leaves on the stems, which significantly affected the final protein yield. The choice of linseed cultivar for oilseed–legume intercropping was of great importance for the final yield. Among the mixtures compared, the one composed of ‘Barbara’ linseed and ‘Phönix’ pea was more productive. Cultivation of ‘Flanders’ linseed resulted in high yield in the pure stand and a high-fat yield. Intercropping of linseed with pea resulted in REI values above 1, which demonstrates the agrobiological suitability of the mixture.

    Abstract In this research the feasibility of agricultural crop residues used as alternative raw materials for particleboards was investigated. Germany-grown cup-plant (Silphium perfoliatum L.), sunflower (Helianthus annuus L.) and topinambour (Helianthus tuberosus L.) were used as raw materials for particleboards produced at a conventional density of 600kg/m3. Particleboards were glued with two different adhesives, with methylene diphenyl diisocyanate (MDI) as well and urea formaldehyde (UF) resins. The physical and mechanical properties of prepared panels were measured according to standards. The raw materials were analyzed for their chemical composition; particle geometry was carefully monitored. It is shown that the obtained particleboards have acceptable performances, though properties were below those obtained from conventional spruce particleboards. Modulus of rupture of the alternative material particleboards were found to be lower than the spruce particleboards. Likewise, thickness swelling and water absorption of the agricultural residues made particleboards were higher than the compared spruce-made particleboards. The finding relevant for industrial applications was that the agricultural residue-produced particleboards bonded with MDI resins fully comply with the European standard EN 312 class P1 (use in dry conditions). This means that non-wood particleboards are suitable to be used in furniture production.

  10. Article ; Online: Effect of Elicitation with (+)-Usnic Acid on Accumulation of Phenolic Acids and Flavonoids in Agitated Microshoots of Eryngium alpinum L.

    Abstract: ... of phenolic compounds in in vitro shoot cultures of Eryngium alpinum L., a protected plant from the Apiaceae family ...

    Abstract The present work was aimed at studying the potential of elicitation on the accumulation of phenolic compounds in in vitro shoot cultures of Eryngium alpinum L., a protected plant from the Apiaceae family. The study examined the influence of (+)-usnic acid on the biomass growth as well as on the biosynthesis of the desired flavonoids and phenolic acids in the cultured microshoots. The phenolic compound content was determined by HPLC-DAD. The flavonoid of the highest concentration was isoquercetin, and the phenolic acids of the highest amount were rosmarinic acid, caffeic acid and 3,4-dihydroxyphenylacetic acid, both in the non-elicited and elicited biomass. Isoquercetin accumulation was efficiently increased by a longer elicitation with a lower concentration of lichenic compound (107.17 ± 4.67 mg/100 g DW) or a shorter elicitation with a higher concentration of acid (127.54 ± 11.34 and 108.37 ± 12.1 mg/100 g DW). Rosmarinic acid production generally remained high in all elicited and non-elicited microshoots. The highest content of this acid was recorded at 24 h of elicitation with 3.125 µM usnic acid (512.69 ± 4.89 mg/100 g DW). The process of elicitation with (+)-usnic acid, a well-known lichenic compound with allelopathic nature, may therefore be an effective technique of enhancing phenolic compound accumulation in alpine eryngo microshoot biomass.
