    Opis:
    Methyl jasmonate has a strong effect on secondary metabolizm in plants, by stimulating the biosynthesis a number of phenolic compounds and alkaloids. Common buckwheat (Fagopyrum esculentum Moench) is an important source of biologically active compounds. This research focuses on the detection and quantification of 2-phenylethylamine and its possible metabolites in the cotyledons, hypocotyl and roots of common buckwheat seedlings treated with methyl jasmonate. In cotyledons of buckwheat sprouts, only traces of 2-phenylethylamine were found, while in the hypocotyl and roots its concentration was about 150 and 1000-times higher, respectively. Treatment with methyl jasmonate resulted in a 4-fold increase of the 2-phenylethylamine level in the cotyledons of 7-day buckwheat seedlings, and an 11-fold and 5-fold increase in hypocotyl and roots, respectively. Methyl jasmonate treatment led also to about 4-fold increase of phenylacetic acid content in all examined seedling organs, but did not affect the 2-phenylethanol level in cotyledons, and slightly enhanced in hypocotyl and roots. It has been suggested that 2-phenylethylamine is a substrate for the biosynthesis of phenylacetic acid and 2-phenylethanol, as well as cinnamoyl 2-phenethylamide. In organs of buckwheat seedling treated with methyl jasmonate, higher amounts of aromatic amino acid transaminase mRNA were found. The enzyme can be involved in the synthesis of phenylpyruvic acid, but the presence of this compound could not be confirmed in any of the examined organs of common buckwheat seedling.

    Opis:
    In laboratory experiments, the impact of elicitation with a mixture of sodium silicate and iron chelate or sodium silicate alone on fatty acid composition in sprouts of common buckwheat (Fagopyrum esculentum Moench) has been examined. Buckwheat seeds and then sprouts were soaked for 0.5 h each day over six days in an aqueous solution of the mentioned elicitors. The sprouts were grown in the light regime of 16/8 h, day/night. After seven days of germination (sprouting), the composition of fatty acids in freeze-dried and powdered sprout tissues was analyzed by gas chromatography. The results showed significant changes in the composition of fatty acids in sprouts in comparison to buckwheat seeds. The results indicate that the germination of buckwheat seeds leads to an increase in myristic (C14:0), palmitic (C16:0), stearic (C18:0) and behenic (C20:0) acid in sprouts, although the use of the elicitors, especially sodium silicate, inhibited this tendency. The sprouts of common buckwheat contained almost twice as much α-linolenic acid (C18:3) as the seeds did, and slightly less linoleic acid (C18:2). Moreover, the use of elicitors favored an increased accumulation of α-C18:3. As a result, germination drastically reduced the C18:2/a-C18:3 ratio by about 4 times, which may have a positive health effect. The buckwheat sprouts contained traces of eicosatrienoic (C20:3), eicosatetraenoic (C20:4), docosaenoic (C22:1) and docosadienoic (C22:2) acids, while their content in the seeds was between 0.6 and 2.4%. The buckwheat sprouts had a higher atherogenic (AI) and thrombogenic index (TI) and a lower health index (HI) than seeds did, but the use of elicitors inhibited this tendency.

    Opis:
    The article presents a data analysis and processing for tuning artificial neural network (ANN) of the anthrop technical system reliability, based on the opinions of experts. In general, the system reliability parameters are functions of operands – physical values – like time to failure, time between failures, duration times of specific reliability or operational states, number of failures in a time interval (event frequencies). These values are easier to be determined by an expert – operator with long year experience – than probabilistic model parameters. It is suggested that they be used in elicitation, for example linguistic estimates of the shares of reliability system elements in the system failure frequency. The numerical – linguistic elicitation of these opinions was carried out, which turned out to be uncorrelated and not suitable for tuning the network. Data processing method was used with the appropriate adopted analytic hierarchy process (AHP) geometric scale and matrix approximation method evaluations (logarithmic least squares method). Correlation analyses were performed for received input and output data of network and error of data processing method was determined. The results are shown in the example of elicitation and data correlation analyses for tuning the reliability neural network of the ship propulsion system.

    Opis:
    Eryngium planum L. has been reported as a medicinal plant used in traditional medicine in Europe. The tissue cultures may be an alternative source of the biomass rich in desired bioactive compounds. The purpose of this study was to investigate the influence of the biotechnological techniques on the selected phenolic acids accumulation in the agitated shoot cultures of E. planum. Qualitative and quantitative analyses of those compounds in 50% aqueous - methanolic extracts from the biomass were conducted by applying the HPLC method. Methyl jasmonate (MeJA), yeast extract (YE) and sucrose (Suc) stimulated accumulation of the phenolic acids: rosmarinic (RA), chlorogenic (CGA) and caffeic (CA) in in vitro shoot cultures. Cultivation of shoots in liquid MS media supplemented with 1.0 mg L-1 6-benzyladenine and 0.1 mg L-1 indole-3-acetic acid in the presence of 100 µM MeJA for 48h was an optimum condition of elicitation and resulted in approximately 4.5-fold increased content of RA + CGA + CA in plant material compared to the control (19.795 mg g-1 DW, 4.36 mg g-1 DW, respectively). The results provide the first evidence that the selected phenolic acids can be synthesized in elicited shoot cultures of flat sea holly in higher amount than in untreated shoots.

    Opis:
    Phenolic acids are an important group of plant secondary metabolites with various, valuable therapeutic properties. Apart from plants growing in the open air, tissue cultures can be an alternative source of the secondary metabolites. The yield of their accumulation in in vitro cultures can be increased by different methods, including culture medium supplementation with precursors, elicitors and changing the standard amounts of the medium components. The purpose of this study was to investigate the influence of the precursor (L-phenylalanine), the elicitor (methyl jasmonate) and a higher sucrose concentration on the phenolic acids accumulation in the agitated shoot cultures of Exacum affine Balf. f. ex Regel (Gentianaceae). Qualitative and quantitative analyses of the phenolic acids in methanolic extracts from the biomass were conducted by applying the HPLC method. Fourteen phenolic acids and cinnamic acid were found in all samples. The total content of free phenolic acids increased from approximately 0.242% to 0.635% (2.6-fold) and the total content of the whole phenolic acids (free and bound) - from 0.712% to 1.160% (1.6-fold). The studies show that the best variant for the accumulation of most of the identified phenolic acids contained 6% of sucrose (double the standard amount), L-phenylalanine 1.6 gL-1 of medium and methyl jasmonate 100 μM. The analysis of the results in the experiment presented here showed that it is possible to increase the accumulation of the phenolic acids in Exacum affine shoot cultures - by adding the precursor (L-phenylalanine), the elicitor (methyl jasmonate) and by increasing the sucrose concentration.

    Research on collocational competence, which is a component of lexical competence, is part of more general research on the acquisition of vocabulary. The methodology adopted in such research continues to evolve. The present article overviews some elicitation techniques for measuring the acquisition of collocations which have been used so far, focusing on their weaknesses. Another focus of the article is innovative and unconventional techniques of elicitation, which are not only an effective measure of the growth of students’ receptive and productive collocational competence, but also a means of raising their collocational awareness.
