in this study nine new varieties of sunflower seeds were obtained and subjected to oil extraction using soxhlet apparatus. the extracted oil was analyzed for fatty acid composition and phosphorus content to measure the phospholipid concentration. the results indicated that armavirski variety had the highest oil content. the fatty acid composition of the extracted oils indicated that armavirski ...

functionality of marve seed gum (salvia macrosiphon boiss) on rheological properties and staling of baguette bread have been studied. three different concentrations of 0.1 %, 0.5% and 1% (w/w, flour basis) were applied and this hydrocolloid affected the quality of the stored bread to some extent. the effects of marve seed gum on the rheological properties of dough was also investigated instrume...

objective: ageing of the stored seed is a natural phenomenon and the seeds tend to lose viability even under ideal storage conditions. accelerated ageing has been recognized as a good predictor of the storability of seed lots. aged seeds show decreased vigor and produce weak seedlings that are unable to survive once reintroduced into a habitat. the characteristics of the chemical composition of...

charcoal rot, caused by macrophomina phaseolina, is one of the most important diseases of sunflower in golestan province. host resistance may be the only feasible method to manage this disease. accordingly, the resistance of 18 varieties of common recommendations for the region in the form of a randomized complete block design (rcbd) against isolates of m. phaseolina was assessed. statistical a...

Twenty-five mature Small Tail Han ewes were used to investigate the effects of supplemental oilseeds in the diet (sunflower seed, safflower seed, rapeseed, and linseed) on fatty acid composition in different tissues (longissimus lumborum muscle, tail fat, subcutaneous back fat and kidney fat). Averaged over tissue, safflower and sunflower seed was most effective (P<0.05) in enhancing the concen...

The main component of the byproducts of flue gas desulfurization (BFGD) is CaSO(4), which can be used to improve sodic soils. The effects of BFGD on sodic soil properties and sunflower growth were studied in a pot experiment. The experiment consisted of eight treatments, at four BFGD rates (0, 7.5, 15 and 22.5 t ha(-1)) and two leaching levels (750 and 1200 m(3) ha(-1)). The germination rate an...
