“…This approximately 10°C increase in temperature generated an average oleic acid content increase of approximately 35 % and a corresponding average linoleic acid content reduction of approximately 35 %. According to Demurin et al [20], an increase in temperature of 1°C may increase the oleic acid content of sunflower seed oil by up to 2 %. Thus, a temperature increase of 10°C would theoretically increase the oleic acid content by up to 20 %.…”

The influence of temperature on the fatty acid composition of the oils from conventional and high oleic sunflower genotypes grown in tropical regions was evaluated under various environmental conditions in Brazil (from 0° S to 23° S). The amounts of the oleic, linoleic, palmitic and stearic fatty acids from the sunflower oil were determined using gas chromatography (GC). The environment exhibited little influence on the amounts of oleic and linoleic fatty acids in high oleic genotypes of sunflower. In conventional genotypes, there was broad variation in the average amounts of these two fatty acids, mainly as a function of the minimum temperature. Depending on the temperature, especially during the maturation of the seeds, the amount of oleic acid in the oil of conventional sunflower genotypes could exceed 70 %. Higher temperatures led to average increases of up to 35 % for this fatty acid. Although the minimum temperature had the strongest effect on the fatty acid composition, locations at the same latitude with different minimum temperatures displayed similar values for both oleic acid and linoleic acid. Furthermore, minimum temperature had little influence on the amounts of palmitic and stearic fatty acids in the oil.

“…During seed development, temperature significantly affects the oleic acid content. Every 1 °C increase in temperature causes a 2% increase in oleic acid content (Demurin et al, 2000). Sunflower genotypes may show different characteristics under different environmental conditions (Qadir et al, 2006).…”

This study aimed to determine the oil ratios and fatty acid compositions of sunflowers grown in the warm climate of the Çukurova region at different sowing dates. Ot was found that the crude fat ratios of standard, mid-oleic and high-oleic sunflower types were 42.57%, 39.35% and 39.07%, respectively. Crude oil ratios of high-oleic and mid-oleic sunflower types were significantly decreased (p<0.05) at SD4 (sowing date 4, May 30th). The oleic acid contents in standard, mid-oleic and high-oleic sunflower types were found to be 60.08%, 74.35% and 88.1%, respectively. The oleic acid ratios of standard sunflower types were determined to be significantly lower at SD1 (April 15th) (p<0.05). The results show that it is more appropriate to sow the sunflowers between SD1 and SD2 (15 April to 30 April) in terms of producing the required oil and oleic acid contents. Also, both oil ratios and fatty acid compositions can change according to the sowing dates.

“…Its use in proper amount positively affects yield and quality of the crop. Sulfur increases the percentage of oil in seeds and plays an important role in chemical composition [15]. Sulfur is an ingredient of coenzymes, vitamins, biotin, thiamine and S-glycosides.…”

Sunflower is an important edible oil seed crop. Adequate amount of nutrients are required for sunflower to get maximum yield. A field trial was conducted at Agronomy Research Farm, The University of Agriculture, Peshawar during Summer 2016 with the objective to investigate the effect of potassium levels (30, 60, 90 and 120 kg ha-1) and sulfur levels (15, 30, 45 and 60 kg ha-1) on oil and grain yield of sunflower. The experiment was conducted in randomized complete block (RCB) design with three replications. One control plot with no potassium and sulfur was maintained in each replication. Ammonium sulfate and Potassium chloride were applied as a source for sulfur and potassium, respectively. The results showed that palmitic acid concentration and stearic acid concentration were not affected by potassium and sulfur application. Potassium applied at the rate of 90 kg ha-1 produced maximum biological yield (7178 kgha-1), grain yield (2074 kg ha-1), oil yield (775 kg ha-1), harvest index (28.87 %) and oil percentage (37.32 %). Sulfur applied at the rate of 60 kg ha-1 produced maximum grains capitulum-1 (873), thousand grain weight (46.63 g), grain yield (2037 kg ha-1), oil yield (771 kg ha-1), harvest index (29.54 %), oil percentage (37.81 %) and linoleic acid concentration (78.80 %). Non-significant effect of sulfur was observed on biological yield of sunflower. Application of potassium at the rate of 90 kg ha-1 and sulfur at the rate of 60 kg ha-1 could be recommended for higher oil and grain yield of sunflower.
