“…Under this condition, the SUN plants would be highly shaded and the intercepted solar radiation and temperature would be decreased. The oleic acid grain concentration of sunflower might decrease with a decrease in temperature due to shading during grain filling (Echarte et al, 2010).…”

The Helianthus annuus taxon includes the wild (ruderal), weedy (agrestal) and volunteer biotypes, which may share space and time with the sunflower crop. The agrestal biotype is one of the most harmful weeds challenging the use of modern biotechnological tools in sunflower. The interference of the agrestal biotype was studied at a range of weed densities within a sunflower crop. The area of influence of one agrestal plant was estimated as a circular area of more than 2.5 m 2 . The agrestal biotype at 10.7 plants m À2 reduced the sunflower seed production by 66%, the seed weight by 41% and the yield by 80%. The agrestal biotype showed intermediate vegetative stage duration between sunflower and the ruderal biotype. The interference of the agrestal biotype would be due to its high initial growth rate, its larger leaf area and plant height. Some agrestal plants showed partial dehiscence at the sunflower harvest stage replenishing the soil seedbank with over 18 000 seeds m À2 . The sunflower harvest operation and grain storage might be affected due to a fraction of agrestal plants remaining alive and moist when the crop reached harvest maturity. The results support the recommendation of preventing the entry of the agrestal biotype into crop production fields.

“…Standard type sunflowers showed the oil properties of mid-oleic sunflowers according to the same classification. Piva et al (2000), Echarte et al (2010) and Merwe et al (2013) reported that the oleic acid concentrations were higher in warmer and drier environmental conditions. While the oleic acid ratios of high-oleic and mid-oleic sunflowers were similar to the previous studies done by Ozquierdo et al (2002), Flagella et al (2002) and Zheljazkov et al (2011), they were found to be more than the results in the study done by Merwe et al (2013).…”

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.

“…Seeds from plants grown in Spain had higher oleic acid content and lower linoleic acid content than plants grown in Morocco (Table 2), which was probably attributable to differ- ences in the minimum daily temperature, which averaged 18.4°C during the seed filling period in the location in Spain and 16.8°C in the location in Morocco. Echarte et al (2010) found that small changes of minimum temperature in the range from around 15 to 25°C produced large changes in oleic acid content and concomitantly in the levels of other fatty acids, in such a way that reduced temperature were associated with reduced oleic acid content.…”

“…Finally, the analysis of variance showed a pronounced effect of the location on the fatty acid profile, with the genotype × location interaction being only significant for stearic acid and linoleic acid content (Table 1). Previous studies have emphasized the influence of the environment on the fatty acid content of sunflower seed oil, particularly on oleic acid and linoleic acid content (Canvin, 1965;Echarte et al, 2010).…”

Sunflower seeds are one of the most important sources of vegetable oil in the world. Additionally, they are used for confectionery and snack food, as well as for bird and pet food. Sunflower germplasm used for food differs between Morocco and Spain. Whereas sunflower seeds used for food in Morocco are mainly obtained from oilseed-type cultivars with black achenes and low hull proportion, those used in Spain derive from confectionery-type cultivars with black and white striped achenes and high hull proportion. The objective of this research was to evaluate the performance and seed quality of Moroccan and Spanish sunflower germplasm used for food. Six cultivars from Morocco and six landraces from Spain were evaluated in replicated field trials in Aïn Taoujdate (Morocco) and Córdoba (Spain) in 2009. Seed yield, hundred-achene weight, hundred-kernel weight, achene oil content, kernel oil content, and fatty acid profile were measured. The results showed that confectionery-type and oilseed-type cultivars did not differ in seed yield, hundred-kernel weight and kernel oil content. Since confectionery-type cultivars from Spain performed similarly to local oilseed-type cultivars, they could be introduced to diversify the offer of in-shell sunflower seed snack in Morocco.
