The content of selected elements in common flax seeds (Linum usitatissimum L.) depending on the cultivar and weather conditions

Flax (Linum usitatissimum L.), grown throughout the world for millennia. It is a multipurpose agricultural crop that can provide food, fuel and fibre. An agro-morphological characterization based on 13 traits of 26 flax accessions was carried out during the Rabi season 2017-2018 at the Agricultural Research Station, Bangladesh Agricultural Research Institute, Rangpur. The field experiment was laid out in a randomized completed block design having four replications. Flax seeds were sown in 3.0 m × 0.6 m plot with continuous line sowing (two lines). The seed germination (%) and vigour indices of all flax accessions varied from 44.1 – 77.7 and 44.1 – 119.4, respectively. A significant variation in all growth and yield attributing descriptors was observed except 1000-seed weight of flax. Among the accessions, BD-10708 possessed the highest seed yield (182.9 g plant–1) and yield attributing descriptors viz., number of capsules plant–1 (142) and seeds plant–1 (513) of flax. The performance of the local accesson Ulipur was observed poor compared to some of the test accessions of flax. Some of these flax accessions could be used as breeding materials in varietal developmental and improvement programmes with higher yield potentials of flax in Bangladesh.

In the comparative variety testing it was evaluated promising material of fiber-flax (Linum usitatissimum L.). The aim of the work was to identify the most valuable cultivar fiber-flax according to their economic and biological characteristics, and adaptability to adverse environmental factors. Valuable forms of fiber-flax on the main economically significant features were identified in the Smolensk region. The total length of the stem of A-11 and L-198 exceeded the standard S-108 by 8 - 10%. The duaration of the growing season in all studied varieties was 5 days longer than that of the standard variety. L-198 exceeded the standard S-108, both in yield of flax straw and fiber content in the stem, the excess was 9 and 3%, respectively. The highest yield of flax seeds (0,58 t/ha) was also in L-198 (21% higher than in the standard). The yield of long fiber in the stem of this sample was 20,1%, which is 0,8% higher compared to the standard. The calculation of the economic efficiency of cultivation of the L-198 variety for fiber-flax seeds also showed its advantage over the S-108 standard.

New Crop

In 1971, the percentage of poorly matured flax seeds (Linum usitatissimum L.) in southern Manitoba was unusually high. This seed was discolored and tended to clump due to portions of the capsule septa adhering to the seed coat. Samples of flax seed selected from the new crop survey conducted by the Canadian Grain Commission were divided into normal and poor or weathered seeds. The poor seeds had a lower seed weight, lower percent germination, and darker oil, but an iodine number higher than the normal seeds. There were no consistent differences in oil and protein content. It appears that seeds with this type of weathering are acceptable for crushing but unacceptable for seeding.

Flax Seeds

Background: Hyperlipidaemia is a chronic progressive disease, which encompasses various genetic and acquired conditions resulting in inappropriately elevated lipid levels in humans. Several preclinical and clinical studies have demonstrated that dietary supplementation with Linum Usitatissimum have beneficial cardiovascular effects like antihypertensive action, antiatherogenic effects, lowering of cholesterol, anti-inflammatory action and inhibition of arrhythmia. There are few studies on hepatoprotective effects of flax seeds in hyperlipidemic animal models. Aim and objectives: Hence, this study was undertaken to evaluate the hypolipidemic and hepatoprotective effect of Linum seeds. Methods: The study was conducted for the period of two months in Department of Pharmacology KIMS, Bhubaneswar. Total 36 Albino wistar rats were taken and divided into 6 groups containing 6 rats each. Group II was hypercholesterolemic (HC) control, Group III was treatment control and Group IV to VI rats were given different doses of extract. Blood samples were taken at the end of two months. Results: All the values are expressed as Mean±SD (standard deviation). Significant decrease in lipid parameters and liver enzymes is seen at the end of two months in all 3 groups receiving the extract, where the highest dose of extract used, is near to the standard drug. Conclusion: From this study, it can be concluded that the addition of the flaxseeds to the diet may alleviate the rise in circulating cholesterol levels induced by the high cholesterol diet through its content of alfa-linolenic acid (ALA) and lignins. The hepatoprotective role of flaxseed in hypercholesterolaemia has also been demonstrated in this this study.

Summary 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.
