Introduction: Polish oilseed and flaxseed collection is a source of genotypes containing very high amounts of α-linolenic acid. Objective: The objective of the study is to test the seeds for the fat content and fatty acids composition in the oil pressed from the 9 tested accessions of flax (Linum usitatissimum L.). Our goal is to promote the Polish flax collection, which seeds are unique as one of the richest sources of α-linolenic acid. Methods: Assays to determine the content of fat and fatty acids composition in linseed oil were performed at the IHAR-PIB Biochemical Laboratory in Poznań. The fat content was determined by infrared analysis (calibration performed on the basis of seed sample at IHAR-PIB in Poznań) by means of a NIRS 6500 spectrophotometer with a reflection detector within the range of 400–2500 nm. The composition of fatty acids was determined by means of a method proposed by Byczyńska and Krzymański (1969), based on gas chromatography of methyl esters of fatty acids contained in linseed oil. The following varieties of flax were investigated: Tabare (INF00111), Szegedi 30 (INF00427), Olin (INF 00444), Redwood 65 (INF00523), Dufferin (INF00540), AC Mc Duff (INF00648), Alfonso Inta (INF00683), Olinette (INF00687), Royale (INF00689). Results: The content of α-linolenic acid (ALA, C18:3) in evaluated genotypes of flax ranged from 48.9 (Royale) to 59.9% (Alfonso Inta). Content of linoleic acid (LA, C18:2) in evaluated genotypes of flax ranged from 12.4 (Tabare) to 17.1% (AC Mc Duff). The content of oleic acid (OA, C18:1) of 9 accession of flax ranged from 17.1 (Alfonso Inta) to 26.7% (Royale). The content of stearic acid in evaluated genotypes of flax ranged from 2.3 (Alfonso Inta) to 5.0% (Tabare, Szegedi 30) and the content of palmitic acid ranged from 4.7 (Dufferin) to 6.0% (Olin). The content of fat ranged from 42.7 (Olin) to 52.0% (AC Mc Duff). The fatty acid ratio n-6/n-3 ranged from 0.23/1 (Tabare) to 0.32/1 (AC Mc Duff).

Germination of flax seeds (Linum usitatissimum L., cv. Szafir) at 5oC was enhanced by continuous white light, gibberellin A3 (GA3), kinetin and benzylaminopurine. GA3 and kinetin at physiological concentrations (10-8-10-6 M) improved significantly germination in darkness. Stimulatory effect of benzylaminopurine was visible only in the light. Almost no effect of zeatin and isopentenyladenine (2iP) on germination was observed. Possible causes of this differences were suggested.

We expanded the basic ISSR-PCR protocol by an additional PCR reamplification round in order to detect whether increased PCR productivity would give new bands in ISSR patterns. We found that the reamplification step had a prominent impact on the quality of the inter-simple-sequence repeat (ISSR) PCR patterns of flax, depending on the particular primer used for PCR amplification. We could clearly distinguish between two types of reamplification effect. Most ISSR primers (16 out of 21) gave no reamplification effect as usual, but five primers (23.8%) provided a new ISSR fingerprinting pattern after the 2nd reamplification round, leaving the previous 1st round pattern completely blank. Therefore, we recommend the expansion of a basic ISSR-PCR protocol for another reamplification round in order to mine out full the fingerprinting potential from ISSR-PCR method.

Anther culture is currently the most successful method for production of doubled haploid lines in flax. Recently, ovary culture was also described as a good source of doubled haploids. In this contribution we investigated the incorporation of enzyme polymorphism of acid phosphatase and peroxidase as molecular markers for the gametic origin of flax plants derived from anther and ovary cultures.

Total petroleum hydrocarbons (TPHs) are one of the most common groups of persistent organic contaminants. Plant-based remediation is a relatively new, efficient and environmentally friendly technology that can be promising for removing many contaminants like hydrocarbon pollutants. The main objectives of the current research were to investigate the phytoremediation efficiency of burningbush, flax, and tall fescue as well as the influence of petroleum hydrocarbons on growth characteristics of these plant species. In order to improve soil condition and study the effect of fertilization on plant growth in oil-contaminated soil, peat fertilizer was applied in a separate treatment. Unfertilized as well as fertilized soil samples were analyzed for TPH removal by GC-FID in different time intervals. All plant species showed promising growth behaviour in highly contaminated soil. A decrease of TPHs was found over the course of the experiment in all treatments. The maximum removal was obtained in flax, in which flax removed 97.9% of the initial TPHs from soil. Results demonstrated that the three studied plant species were effective and promising in removing TPHs from contaminated, aged soil.

Flax is a valuable source of fibers, linseed and oil. The compounds of the latter two products have already been widely examined and have been proven to possess many health-beneficial properties. In the course of analysis of fibers extract from previously generated transgenic plants overproducing phenylpropanoids a new terpenoid compound was discovered. The UV spectra and the retention time in UPLC analysis of this new compound reveal similarity to a cannabinoid-like compound, probably cannabidiol (CBD). This was confirmed by finding two ions at m/z 174.1 and 231.2 in mass spectra analysis. Further confirmation of the nature of the compound was based on a biological activity assay. It was found that the compound affects the expression of genes involved in inflammatory processes in mouse and human fibroblasts and likely the CBD from Cannabis sativa activates the specific peripheral cannabinoid receptor 2 (CB2) gene expression. Besides fibers, the compound was also found in all other flax tissues. It should be pointed out that the industrial process of fabric production does not affect CBD activity. The presented data suggest for the first time that flax products can be a source of biologically active cannabinoid-like compounds that are able to influence the cell immunological response. These findings might open up many new applications for medical flax products, especially for the fabric as a material for wound dressing with anti-inflammatory properties.

Linseed, one of the oldest cultivated crops, is again gaining in importance, mainly due to its nutritional benefi ts and biomedical applications. Th erefore, it is expected that herbivores will also exist in greater abundance. Among them the fl ea beetle, Aphthona euphorbiae Schrank and Longitarsus parvulus Paykull are considered to be serious pests of fl ax grown for fi bre and seeds in Europe. Th e aim of this study was to determine fl ax fl ea beetles’ abundance, species richness and seasonal dynamics on linseed grown at diff erent densities. It was expected that linseed seeding density can signifi cantly aff ect fl ea beetle populations. Th e experiment was carried out in Lower Silesia, Poland, from 2011 to 2013. A genetically modifi ed type of linseed overproducing fl avonoids was used. Flea beetles and the damages they caused were determined on plants and also a sweep net was used for the collection of adult beetles. During the three years of the study 15 species of fl ea beetles were identifi ed from oil fl ax plants, with A. euphorbiae and L. parvulus being dominant. In terms of the total catch, the tendency was for beetle numbers to decrease with increasing plant density. Flax fl ea beetles feeding on linseed plants, irrespective of plant density, had two peaks of abundance. Th e fi rst peak was lower and occurred in June, when plants were at the blooming stage. Th is peak was caused by overwintering adults who colonized crops in spring. Th e second, higher peak of abundance was recorded in the second half of July, when plants were at the ripening stage. Th is peak was formed by adults of the new generation. Each year, at the higher population peak of abundance, the fl ea beetles were most numerous on plants grown at the lowest density. Th ere was one period, lasting either from mid-May to the fi rst few days of June, or from the beginning of June to mid-June, during which the number of holes and damage on plants of each treatment were highest. During the three years of the study there were several cases of signifi cantly higher numbers of fl ea beetle feeding symptoms on plants grown at the lowest density as compared to the medium and highest densities.

Influence of Cd(NO3)2 concentration on the process of flax (Linum usitatissimum L.) germination and changes occurring on the level of synthesized proteins or peptides were evaluated. The studies did not reveal differences in seed germination in control conditions and in presence of cadmium solution. Extracts obtained from two-week-old seedlings were exposed to ammonium sulphate saturation (0–30 and 50–80%). Ion exchange chromatography on DEAE Cellulose revealed appearance of proteins or peptides rich in the cysteine residues which were not present in control group (absorbance 280 and 254 nm). Particular proteins were observed in three extract fractions eluted by NaCl gradient (0.3–0.5 M NaCl) what could suggests formation of (Cys-rich) protein or peptides in presence of the cadmium solution during detoxification process. The largest absorbance indicated a high concentration of (Cys-rich) proteins or peptides related probably to incubation with cadmium solution observed at extract fraction eluted with 0.4 M NaCl.
