“…Dil is synthesized from carbohydrates either from current photosynthesis or from the remobilization of storage carbohydrates. Therefore, oil accumulation greatly depends on the carbon economy and photosynthesis ratio of the crop during seed filling (Aguirrezábal et al, 2009 Riedell et al (2009) reported that variations in seed protein concentration induced by weather, water and nitrogen availability, response to temperature, solar radiation, CD 2 , regional conditions, and growing techniques are much larger than variations due to genotype. Yalcin et al (2011) investigated the protein and oil content of flaxseed grown in 2008 and 2009.…”

The objective of this research was to determine the effect of five years on physico-chemical characteristics and antioxidant activity of flaxseed hull oils. Dil and protein on flaxseed hull varied between 20.15 and 22.56 and 17.45 and 19.14, respectively. The albumin fraction dominated the seed hull protein composition (44 -47%). Flaxseed hull oils showed significantly high unsaturated to saturated fatty acid ratios (6.61 -8.36) and calculated oxidizability (Cox) values (10.88 -12.30). The physiochemical parameters determined included saponification value (SV) (174 -182 mg KDH/g), unsaponifiable matter (UM) (1.32 -1.64%), peroxide value (PV) (1.70 -2.20 mequiv/kg), Dxidation value (DV) (4.40 -5.90) and oil stability (1.10 -1.42 h). The highest content of total phenolic acids and total tocopherols were recorded on hull sample collected in 2008. Flavanoid content ranged from 11 to 19 mg/100 g oil. Antioxidant activity differed significantly; the greatest inhibition (61.38%) was for the hull sample collected in 2008.Keywords: flaxseed hull oil; antioxidant activity; chemical composition.Practical Application: Practical application for the study entitled "Influence of harvest year in the physicochemical properties and antioxidant activity of flaxseed hull oils from Tunisia" regard the possibility of knowing the chemical composition of flaxseed hull produced in Tunisia from autochthonous variety. It is very important to understand if and how harvest year influence the physicochemical characteristics of flaxseed hull. Valuable information will be provided for flaxseed hull breeders and growers in developing and producing functional food resources and products.

“…Therefore, seed oil accumulation greatly depends on the carbon economy of the crop during seed filling. Insufficient nutrient supply limits the leaf growth rate and thus leaf area due to low rate of photosynthesis (Aguirrezábal et al 2009). Sebei et al (2004) studied at four levels of N fertilization (none, low, medium and high) in rapeseed cultivation and they reported that the highest N fertilizer dose decreased oil content of the rapeseed.…”

“…Thus, severe reduction in leaf N content brought about by insufficient N supply will likely decrease photosynthesis and hence growth and yield and composition of a crop. Otherwise, the effect of other environmental factors and management practices (intercepted radiation per plant, temperature, foliar diseases, sowing date and sowing density) have direct effects on seed oil concentration (Aguirrezábal et al 2009). There are many studies related with the effect of fertilizer on the protein content of oilseeds.…”

“…In the field, variations in seed protein concentration induced by weather, water and nitrogen availability, response to temperature, solar radiation, CO 2 , regional conditions, and growing techniques are much larger than variations due to genotype (Riedell et al 2009). In oil crops, an increase in oil concentration is generally associated with a decrease in protein concentration as a result of a dilution effect (Aguirrezábal et al 2009). We did not observe this dilution effect in our study.…”

Influence of the harvesting year and fertilizer on the fatty acid composition and some physicochemical properties of linseed (Linum usitatissimum L.)

Sarı 85 (Linum usitatissimum L.) linseed variety was used in this study. Linseed was cultivated at 2008 (LS-08) and 2009 (LS-09) without fertilizer. In addition, at 2009 diammonium phosphate [(NH 4 ) 2 HPO 4 ] and ammonium nitrate (NH 4 NO 3 ) were applied (LSF-09). The linseeds were analyzed for protein, ash and oil contents and fatty acid compositions. There were differences among harvesting years for oil, protein and ash contents of the seeds. The greater oil and protein contents were obtained during LS-08 compared with LS-09. There were no significant difference in protein and ash content between LS-09 and LSF-09 while a significant difference was observed in oil content. Seed protein, oil and ash contents were significantly affected by the harvesting year, but only oil content was affected by the fertilizer treatment. There are significant differences in palmitic, stearic, oleic, a-linolenic and arachidic acid between LS-08 and LS-09. While palmitic, stearic, oleic acid decreased, a-linolenic and arachidic acid increased during 2009 harvesting year. LSF-09 has the highest amount of a-linolenic acid. The fertilizing treatment seems to have an increasing effect on the amount of a-linolenic acid, while it has a decreasing effect on the oleic acid content.
