The aim of the study was to determine the effect of linseed and rapeseed dietary supplementation on the fatty acids profiles of two ostrich fat depots: breast and subcutaneous (above the leg). The study was carried out on 40 ostriches raised in five groups – control (C) or with 4% (L4) or 8% (L8) linseed, or 5% (R5) or 10% (R10) rapeseed in the diet, from hatching to 12 months of age. Fat samples of breast (BF) and leg fat (LF) were taken for fatty acids analysis. Generally ostrich fat has high contents of PUFA (BF – 23.9, LF – 20.2 g/100 g FAME), especially linoleic acid (BF – 16.4, LF – 12.5 g/100 g FAME) and linolenic acid (BF – 5.7 and LF – 6.2 g/100 g FAME). Ostrich BF had a higher content of n-6 FA and total PUFA and lower n-3 FA than the LF. Both fat depots had desired PUFA/SFA ratios above 0.4, but not desirable n-6/n-3 ratios. BF had significantly higher (0.69)PUFA/SFA ratio than LF (0.55). Both L4 and L8 caused higher total PUFA content (27.8, 25.6 g/100 g FAME, respectively) and higher PUFA/SFA ratios (0.74, 0.75, respectively) and lower n-6/n-3 ratios (1.5, 1.8, respectively) compared to C. The rapeseed supplementation decreased the LA content in ostrich fats (R5- 14.1, R10-13.4g/100g FAME), causing a lower n-6/n-3 (4.1, 4.6, respectively) ratio compared to C (6.1). The supplementation of ostrich diets with linseed improved the nutritional value of ostrich fat by increasing the n-3 FA, total PUFA content and PUFA/SFA ratio. Although the leg fat had a lower PUFA content, both depots of ostrich fats can be recommended as valuable ingredients for value-added meat products fit for human consumption.

Forty ostriches were raised in five groups [control (C) or with 4% (L4) or 8% (L8) linseed, or 5% (R5) or 10% (R10) rapeseed in the diet]. Linseed supplementation (L4 and L8) improved the nutritive value of the ostrich meat by increasing (P<0.001) the α-linolenic acid content (>4.2%FAtotal) and PUFA/SFA ratio (>1.0) as compared with the control group (1.7% FAtotal and <0.94, α-linolenic acid and PUFA/SFA, respectively), whereas the effect of rapeseed was lower (2.2%, and <0.99, α-linolenic acid and PUFA/SFA, respectively). Dietary treatment lowered (P<0.001) the n-6/n-3 ratio from ca. 11 in the C group to 4 in the L8 and L4 groups. Overall, the results indicate that inclusion of linseed into ostrich diets has a positive effect on the fatty acid composition, allowing the production of meat enriched with n-3 fatty acids

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.

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

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.

In three year field experiments (2001 - 2003) the growth, yield and productivity of 8 flax cultivars were compared. Cultivars ‘AC Linora’, ‘Flanders’, ‘Linola™ 947’, ‘Norlin’ and ‘Omega’ were obtained from Canada, ‘Barbara’ and ‘Hungarian Gold’ from Hungary and ‘Opal’ from Poland. Apart from the estimation of the yield of aboveground parts dry matter and seed yield the det erminat ions of the primary index value of growth analysis were done and on their basis the indices LAI, LAD, RGR, CGR and HI were calculated. The obtained yield results of the examined flax cultivars show significant genotypic - environmental relationships pertaining to the dynamics of dry matter accumulation and the amount of seed yield. Meteorological conditions in the successive years significantly influenced the particular phases of growth and development of cultivars and the factor which increased the amount of dry matter was the air temperature during the period of plant emergence - budding. During the vegetative season with a large amount of rainfall the average seed yield was about 40 % lower than compared with a year of average precipitation and a warm second part of the second period of flax vegetation. Among the analyzed cultivars a stable yield in all the years was characteristic for cultivars ‘Flanders’, ‘Barbara’ and ‘AC Linora’ (that cultivar, however, during a wet year yielded at a low level). The assimilation leaf surface of the linseed quickly increased during the period from budding to flowering and the accumulation of dry matter of the aboveground parts lasted up to the green maturity. In the successive years of the experiment there were observed significant (linear or logarithmic regressions) relationship between the yield of dry matter and the indices of growth analysis. The biggest values of the CGR indicator were observed for the period from budding to flowering. The maintaining of a high CGR value after plant flowering in the year with a favourable course of climatic parameters was beneficial for a better yield of all flax cultivars. The low values of the RGR index after flowering of cultivar ‘Hungarian Gold’ and ‘Opal’ strictly corresponded to their low yield of seed and straw biomass.
