The effect of bio-priming on germination and deteriora tion control of flax seeds (Linum usitatissimum)

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.

Flax Seeds

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.

The objective of this study was to determine species-associated differences in the seed proximate and fatty acid composition of three traditional oil crop species, hemp (Cannabis sativa), flax (Linum usitatissimum), and camelina (Camelina sativa), and the sowing season of camelina harvested under Lithuanian farming conditions for food use. Camelina seeds had the highest (p < 0.001) content of protein, oil, and sugar contents compared to both dehulled hemp and flax seeds. The amounts of protein and oil in camelina seeds were considerably increased by their summer cultivar, which showed higher (p < 0.001) contents of protein and oil than winter cultivars. However, the highest and lowest (p < 0.001) fiber content was found in flax seeds and camelina seeds, respectively. Camelina seeds showed considerably higher and lower (p < 0.001) proportions of total monounsaturated (MUFA) and polyunsaturated (PUFA) fatty acids, respectively, compared with hemp and flax. The summer cultivar of camelina had higher (p < 0.001) proportions of saturated (SFA) and MUFA and lower proportions of PUFA compared with winter cultivars. Hemp seeds had the highest and lowest (p < 0.001) proportions of PUFA and MUFA, respectively. The n-6/n-3 PUFA ratio in hemp seeds is optimal (3.79), whereas the use of flax and camelina seeds with their n-6/n-3 ratios of 0.28 and 0.48, respectively, can significantly improve this ratio in the overall diet. The properties of oil crop seeds showed that whole seeds of hemp, flax, and camelina are potentially highly beneficial to human health.

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.

Obesity poses a major threat to global health, challenging the prevention of chronic diseases and health across the world. As synthetic medicines have their side effects, lately, there has been an inclination towards herbal remedies. The present study was conducted to evaluate the individual and syngeristic effect of Linum usitatissimum (flax seeds), Trigonella foenum graecum (fenugreek seeds) and Nigella sativa (black seeds) on obesity. In-vivo studies were performed in Drosophila as many tissues and organs related to obesity and its associated disorders are analogous in Drosophila and humans. Obesity was induced by supplementing lipid and high concentration of glucose in the media. The effect of the seeds on obesity was studied by quantitative estimation of lipid content and carbohydrate content in the larvae grown in different media preparations and also by assessment of physical activity of the flies. The study revealed the efficient ability of the seeds to reduce obesity, synergistically as well as individually proving it to be a potential strategy to combat the obesity naturally.

Background: Herbal medications, due to their various biologically active components and less toxic profile, have been popular amongst researchers since decades. One good example is Linum usitatissimum (Lu) commonly known as Flaxseeds. The aim of present study was to assess the anti hyperglycemic and anti dyslipidemic activities of ethanolic extract of flax seeds (Linum usitatissimum) in streptozotocin induced diabetic rat model. Methods: The ethanolic extract of flax seeds (Linum usitatissimum) at a dose of 200 mg/kg and 400mg/kg were given to the streptozotocin-induced diabetic rats for the period of 28 days. FBS, insulin, HbA1c, lipid profile and serum amylase were evaluated and were compared with positive and negative controls and standard drugs like Glimepiride 0.1 mg/kg b.w., Metformin 10mg/kg b.w. and Rosuvastatin 10mg/kg/day b.w. Results: Both doses of flax seeds 200 mg/kg and 400 mg/kg (Linum usitatissimum) extracts demonstrated significant (p<0.001) decrease in FBS of diabetic rats. Mainly Linum usitatissimum at the dosage of 400 mg/kg b.w. showed good efficacy in declining fasting blood glucose levels which was comparable with standard anti hyperglycemic drugs. Both doses of herbal extracts also showed significant decline in triglycerides, total cholesterol, and low-density lipoprotein (LDL-C), very low-density lipoproteins (VLDL-C), and serum amylase levels with prominent improvement in HDL-C levels in diabetic rats compared to positive controls. Conclusion: This study reveals that the flax seeds (Lu) at the dose of both 200mg/kg and 400mg/kg have noteworthy potential to reduce hyperglycemia and dyslipidemia associated with diabetes, therefore may be it is useful in the management of Type-2 diabetes mellitus.

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.
