The article describes differences in a response of linseed cultivars of a different genetic and geographical origin to a set of ecological factors. Variability in productivity traits was revealed to be determined in most cases by a genotype and its interaction with growing conditions. The genotype and environmental conditions exert an equal effect on oil accumulation in seeds and its qualitative composition. Based on the data obtained from the linseed collection, the most ecologically stable genotypes, displaying steadily high seed productivity in combination with high content and quality of oil, were selected.

Iron And Calcium

Linseed (Linum usitatissimum L.) is considered as a nutritious food because of exceptionally high alpha-linolenic acid (ALA) content, dietary fiber, quality protein and phytoestrogens. It is rich in minerals (100 g of seeds contain 350-431 mg of magnesium and 236- 250 mg of calcium) and has very low amount of sodium. It also contains anti-nutritional factors, especially phytic acid that interferes with the bioavailability of nutrients like calcium and iron. Fermentation increases the nutritional quality of foods by reducing anti-nutritional factors. Probiotic cultures viz., Lactobacillus acidophilus, Bacillus mesentericus and lactic acid bacterial isolate LAB-3 were used to produce fermented linseed beverage and the quantity of phytic acid, bioavailability of iron and calcium were estimated. Bioavailability of iron and calcium increased by fermentation. The highest bioavailable iron and calcium were observed in L. acidophilus fermentation (4.40 mg and 250.41 mg /100 g seeds, respectively) followed by LAB-3 and Bacillus mesentericus compared to raw seeds that contain 0.89 mg of iron and 125 mg of calcium /100g of seeds. Phytic acid content was high in raw seeds (1392 mg /100 g seeds) and fermentation with L. acidophilus recorded 856 mg phytic acid /100 g seeds resulting in 38.51 % reduction. LAB-3 and B. mesentericus showed approximately 32 % reduction in phytic acid content. The reduction in phytic acid content is significantly high. Fermentation using probiotic bacteria enhanced the bioavailability of iron and calcium by reducing phytic acid. Hence, this study leads to a conclusion that, microbial intervention can be adopted to reduce the anti-nutritional factors and enhance the nutritional quality of linseed.

Flax (Linum usitatissimum L) yield of stem and seeds and them quality is influenced by a number of harmful diseases but investigation about pathogens in recent years have not been done in Latvia. Each stage of development of disease is important in the pathogen life cycle and requires certain condition. Goal of this study have identify possibilities of the pathogens and were assess disease severity depending on the genotypes on flax in variable environmental conditions. The resistance to the diseases for 24 flax genotypes and standard variety ‘Vega 2’ were evaluated. The field trials have been carried out over the period from 2015 to 2016 at the Research Centre of Priekuli, part of Vilani in Latgale. Disease progress was measured every week, and for each treatment, severity of diseases index and the area under the disease progressive curve (AUDPC) were calculated. The flow cytometry method for detection of flax pathogens was developed. The Fusarium avenaveum was dominating disease and statically significant in both vegetation periods. In 2015 were identified statically significant (p

In field and laboratory studies, flax (Linum usitatissimum L.) was frozen when 40–60% of the capsules were still green. Seed visibly frozen at this stage were of lower weight and density, darker in color, and lower in germinabihty than the fraction of the sample that was not visibly frozen. Also, oil color was darker, oil and protein concentrations and stearic and oleic acid levels were lower, and palmitic, linoleic and linolenic acid levels and iodine values were higher in the frozen than the normal seed. Key words: Flax, Linum usitatissimum, frost damage, seed quality, germination

Linum Usitatissimum L

The results of researches on the influence of the terms of harvesting varieties of fiber flax varieties of different ecological and geographical origin on the productivity of fiber and seeds are given. The optimal harvesting dates for the varieties of Zhuravka, Esman and Kamenyar have been established, depending on the target direction of product use. The highest yield of all fiber of fiber flax was obtained in early yellow maturing term depending on the grade of 3.37 t / ha in the Esman variety and 2.58 t / ha in the Kamenyar variety, and the harvesting of these varieties into other phases of ripeness leads to a decrease of 3,1-15,1%. For the Zhuravka variety, the best harvesting period for obtaining the maximum yield of fiber is the phase of green stiffness – 2.78 t / ha).
