Opis:
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.

Opis:
Introduction: Institute of Natural Fibres and Medicinal Plants (INF&MP) is involved in gathering and evaluation of genetic resources of flax (Linum usitatissimum L.), hemp (Cannabis sativa L.) and medicinal plants, because Poland has signed the Convention on Biological Diversity. Field trials were carried out in 1990–2001 in the Experimental Station in Wojciechów located in Opolskie region. The research material was accessions of genetic resources from the collection of flax, stored at the Institute of Plant Breeding and Acclimatization Institute in Radzików near Warsaw. Objective: The aim of the publication was to evaluate the following biological features of flax: time of beginning of flowering and vegetation period to yellow maturity. Methods: The characteristics data for flax accessions are presented according to the methodology of development of the International Flax Database. Each flax accessions from the world collection of flax genetic resources received one of the following assessments of two vegetation periods: very short, short, medium, long and very long. Descriptors of biological features of flax were used, presented in “List of flax descriptors (L. usitatissimum L.)” edited by Janka Nozkova, published in 2011. These descriptors are used to develop the International Flax Database, which in turn helps in the rapid evaluation of the L. usitatissimum genetic resource collection. Carrying out a detailed characterization of biological features of L. usitatissimum accessions is very helpful for breeders in selecting genetic material for breeding new varieties of flax. Results: The following results were obtained from the time of the beginning of flowering and the vegetation period to yellow maturity. Time of beginning of flowering was the following: very short – 0 accessions, short – 97 accessions, medium – 20 accessions, long – 2 accessions and very long – 0 accessions of flax. The genotypes tested were characterized by the following results in terms of vegetation period from sowing to yellow maturity: very short – 0, short – 37, medium – 62, long – 0 and very long – 0 accessions of flax. Conclusions: Time of beginning of flowering and the vegetation period to yellow maturity shall be revalorised to the International Flax Database for those L. usitatissimum accessions that did not receive the same assessment of the biological features tested in the two or three years of the study.

Opis:
Introduction: In 2020, the Institute of Natural Fibres and Medicinal Plants (INF&MP) implemented the contract No. 7/PW 1.2 – IWNiRZ Poznań/KCRZG/2020 for the performance of a research service under the long-term programme “Creating scientific foundations for biological progress and protection of plant genetic resources as a source of innovation and support for sustainable agriculture and safety food for country”. Objective: The aim of the research was to prepare passport and valorisation data for 33 accessions of flax (Linum usitatissimum L.) sown at the INF&MP Experimental Station in Pętkowo. Methods: The field experiment was conducted on 33 samples of flax seeds, which were sown on an area of 1.6 m2. Morphological features were presented by means of numerical data and their evaluation. The agricultural characteristics (numerical values and percentage of the collective pattern) and lengths of vegetation period were also presented. The evaluation of the performed characteristics of flax accessions was presented numerically and the data were given to the International Flax Database. Results: On the basis of paper documentation, the country of origin of the accessions, the type of genotypes by origin (landrace, variety) and the date of inclusion of the accessions in the flax collection were determined. The results of the characterization of morphological trials were as follows: the total plant length of the flax plants ranged from 51.4 cm (La Estanzuella 117) to 76.5 cm (WUKR 06-417) According to the methodology of the International Flax Database, the total plant length were short (28 accessions), medium short (3) and medium (1). Technical length was usually short (28 accessions) and medium short (4 accessions). Stem thickness for all accessions was medium: 1.6–2.5 mm. The length of the panicle was long only for the Opal variety, for 25 accessions - medium and short for 6 accessions. A number of bolls from panicle was: 9.1–30.8. The 1000 seed weight was low for 25 accessions of flax and very low for 8 genotypes of flax. Conclusions: Both studied vegetation periods were short in the following flax accessions: AC Linora, Manchwrian, Noralta and T-397. Flax genotype WUKR-846 (I2010/0031) should be deleted from the flax genetic resources collection and considered as worthless as breeding material. The WUKR 06-417 accession collected during the field expedition is distinguished by a high fibre content – 27%. The highest seed yield per plot was obtained from the cultivation of the following linseed flax cultivars: Redwood, AC Mc Duff, Norlin, Noralta and Jenny.

Opis:
Antitrypsin activity in germinating common seeds of flax (Linum usitatissimum) was investigated. At the early stage of germination an increase in antitrypsin activity was observed, followed by its decrease during the development of the seedlings. From 6-day-old seedlings a trypsin inhibitor (gerLUTI) was purified. The purification procedure involved fractionation of proteins from seedling homogenate with alcohol and successive chromatography on CM-Sephadex C-25 on immobilised methylchymotrypsin in the presence of 5 M NaCl, and finally on a C18 column in RP-HPLC. The gerLUTI migrated in SDS PAGE as a single band, but in mass spectroscopy analysis it exhibited the presence of at least three forms with molecular masses of 7654 ± 3 Da, 7668/7670 ± 3 Da, and 7687 ± 3 Da. The preparation of LUTI isolated from resting seeds contained only one form, with a molecular mass of 7655 ± 3 Da. LUTI and gerLUTI differed also in methionine contents. LUTI contained two methionine residues, whereas in gerLUTI only a trace of methionine was detected. The obtained results might suggest that during flax seeds germination the inhibitor molecules undergo selective modification, e.g. oxidation at methionine residues, before being degraded by proteolytic enzymes.

Opis:
Len zwyczajny (Linum usitatissimum L.) jest gatunkiem uprawianym od wieków na ziemiach polskich ze względu na swój duży potencjał przemysłowy i żywieniowy. Największe znaczenie mają dwie formy lnu zwyczajnego: oleista, która stosowana jest obecnie głównie w branży spożywczej oraz włóknista uprawiana ze względu na wytrzymałe i trwałe włókna. Odmienne wykorzystanie form użytkowych jest determinowane zróżnicowaną biologią gatunku. Uprawa lnu nie jest szczególnie wymagająca, co pozwala na jego zrównoważoną produkcję. Główny problem stanowi zachwaszczenie i niedobór wody. W pracy przedstawiono charakterystykę głównych form użytkowych lnu, ich uprawę oraz potencjalne wykorzystanie przemysłowe, ze szczególnym uwzględnieniem prozdrowotnych właściwości siemienia lnianego.
Linseed or flax (Linum usitatissimum L.) is an annual species cultivated for centuries in Poland due to its industrial and dietary potential. The highest economic importance have two forms: oilseed (linseed), mainly used in the food industry, and fibrous (flax), cultivated for its strong and flexible fibers. The different utility of those forms are determined by biological differences of species. The cultivation of linseed is not particularly demanding on soil and climatic conditions. It allows for their sustainable production. The main problem is the weeds management and the water deficit. The paper focuses on characteristic of linseed forms of utility, crop cultivation and potential industrial application, with particular emphasis on linseed health benefits.

Opis:
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.

Opis:
The aim of this study was to determine the effect of the level of agronomic practice on the content of N, P, K, Mg, Zn, Cu, Mn, Fe and Ca in linseed seed cultivars (cv. Szafir and Oliwin) sown at a row spacing of 15 cm or 25 cm. A field experiment was carried out in 2010–2012. on mixed rendzina soil. The agronomic practice applied differed in the dosage of nitrogen (40, 60 or 80 kg N ha-1) and in weed control (A. without herbicides; B. with two herbicides, C. with three herbicides). The cultivar Szafir was characterised by a significantly higher content of nitrogen than cv. Oliwin, which in turn had a higher manganese content. The content of potassium, magnesium, zinc and manganese in seeds was higher when flax was sown at the narrower row spacing (15 cm) compared to the 25 cm row spacing. A similar relationship was determined for nitrogen, iron and calcium, but statistical verification did not confirm the significance of these differences. The level of agrotechnology in linseed crop cultivation did not influence the seed concentration of the elements. A slightly higher content of the elements in seeds was detected in the treatments where extensive (40 kg N ha-1, without herbicides) and medium intensive technology (60 kg N ha-1, Linurex 50 WP, Fusilade Forte 150 EC) were used, compared to intensive technology (80 N ha-1, Linurex 50 WP, Fusilade Forte 150 EC, Glean 75 WG). A slightly higher content of Fe and Ca was determined in seeds harvested from the plots where the intensive technology was used. Weather conditions significantly affected the content of K, Mg, Zn and Mn in linseed seeds

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).
Wstęp: Polska kolekcja lnu oleistego i włóknistego jest źródłem genotypów o bardzo wysokiej zawartości kwasu α-linolenowego. Cel: Przedmiotem badań było określenie zawartości oleju tłustego oraz składu kwasów tłuszczowych w wytłoczonym oleju z 9 testowanych obiektów lnu zwyczajnego (Linum usitatissimum L.). Naszym celem jest promocja polskiej kolekcji lnu, której nasiona są unikalne jako jedne z najbogatszych źródeł kwasu α-linolenowego. Metody: Oznaczenia zawartości oleju tłustego i składu kwasów tłuszczowych wykonano w Laboratorium Biochemicznym IHAR-PIB w Poznaniu. Zawartość oleju tłustego oznaczono analizą bliskiej podczerwieni (kalibracja wykonana na bazie prób nasion w IHAR-PIB w Poznaniu) spektrofotometrem NIRS 6500 z detektorem odbicia 400–2500 nm. Skład kwasów tłuszczowych oznaczono metodą opracowaną przez Byczyńską i Krzymańskiego (1969), z wykorzystaniem chromatografii gazowej estrów metylowych kwasów tłuszczowych zawartych w oleju z nasion lnu. Badania obejmowały następujące odmiany lnu zwyczajnego: Tabare (INF00111), Szegedi 30 (INF00427), Olin (INF 00444), Redwood 65 (INF00523), Dufferin (INF00540), AC Mc Duff (INF00648), Alfonso Inta (INF00683), Olinette (INF00687), Royale (INF00689). Wyniki: Zawartość kwasu α-linolenowego (ALA, C18:3) badanych genotypów lnu wynosiła od 48,9 (Royale) do 59,9% (Alfonso Inta). Zawartość kwasu linolowego (LA, C18:2) badanych genotypów lnu wynosiła od 12,4 (Tabare) do 17,1% (AC Mc Duff). Zawartość kwasu oleinowego (OA, C18:1) 9 badanych genotypów lnu wynosiła od 17,1 (Alfonso Inta) do 26,7% (Royale). Zawartość kwasu stearynowego badanych genotypów lnu wynosiła od 2,3 (Alfonso Inta) do 5,0% ( Royale) i zawartość kwasu palmitynowego wynosiła od 4,7 (Dufferin) do 6,0% (Olin). Zawartość tłuszczu wynosiła od 42,7 (Olin) do 52,0% (AC Mc Duff). Stosunek n-6/n-3 wynosił od 0,23/1 (Tabare) do 0,32/1 (AC Mc Duff).

Opis:
The objective of the study was genetic and breeding screening of selected varieties and hybrids of oil flax for in-seed cadmium fixing ability. Seven parental varieties as well as nineteen F1 and F2 hybrids were analyzed. The varieties were crossed in di-allelic scheme, according to the Griffing method II. Significant differences were found in the activity of fixing cadmium from the soil between analysed flax parental forms and hybrids. High variability of tested genotypes, calculated by the variance coefficient, was observed in F1 generation. The variability of tested genotypes in the F2 generation was two times lower. The analysis of general combining ability (GCA) showed that Chinese cultivar Shanxi reduced significantly the fixing cadmium from the soil in combinations of F1 generation crossing. However, the effects of the specific combining ability (SCA) of tested hybrids to reduce the cadmium content in seeds were statistically insignificant. The analysis of genetic components variance showed no significance both in domination and cumulative genes which suggests a complex inheritance pattern of the tested trait.
Celem badań była analiza genetyczno-hodowlana wybranych odmian i kombinacji krzyżowania lnu oleistego pod względem wiązania kadmu z gleby w nasionach. Analizowano siedem odmian rodzicielskich i dziewiętnaście mieszańców pokolenia F1 i F2. Odmiany krzyżowano ze sobą w układzie diallelicznym, według II metody Griffinga. Stwierdzono występowanie istotnych różnic w aktywności wiązania kadmu z gleby pomiędzy analizowanymi odmianami rodzicielskimi i mieszańcami lnu. Wysoką zmienność badanych genotypów, obliczoną za pomocą współczynnika zmienności obserwowano w pokoleniu F1. Zmienność badanych genotypów w pokoleniu F2 była dwukrotnie mniejsza. Analiza efektów ogólnej zdolności kombinacyjnej wykazała, że chińska odmiana Shanxi powodowała istotne obniżenie aktywności wiązania kadmu z gleby w kombinacjach krzyżowania w pokoleniu F1, jednakowoż efekty specyficznej zdolności kombinacyjnej badanych mieszańców, pod względem obniżenia zawartości kadmu w nasionach, były już nieistotne statystycznie. Analiza wariancji komponentów genetycznych wykazała brak istotności zarówno dominowania, jak i addytywności, co sugeruje skomplikowany charakter dziedziczenia badanej cechy.
