Night temperature affects fatty acid composition in sunflower oil depending on the hybrid and the phenological stage

Growth and yield of three sunflower hybrids cultivated for two years under Mediterranean conditions

“…In our study, the high concentration of elaic acid in Oleko is rather anticipated (Skoric, 1992), however, the high concentration in 63A90 was probably due to cross pollination and the insects previously visited the high oleic hybrid (Table 4). Genotype is considered as the main factor that determines the oleic acid concentration as previously suggested by Fernandez et al (1989) and Izquierdo et al (2002), however, cross pollination by honeybees can affect the grain yield and oil content (Nderitu et al, 2008). Moreover, the high temperatures during grain filling until maturity may have also played an important role to the high values observed (Robertson et al, 1971;Anderson et al, 1978;Hazel et al, 1978).…”

Environmental effect on sunflower oil quality

“…al. 2009), night temperature (Izquierdo et al 2002) and hybrids (Zheljazkov et al 2011). This indicates the possibility of producing sunflower oil with improved dietary characteristics through cultivar selection and management of the environment in which the crop will develop by choosing more adequate SD.…”

Effects of High Water Table and Short-Term Flooding on Growth, Yield, and Seed Quality of Sunflower

“…We dried the heads and seeds of the five sampled plants were dried using the same method as Izquierdo et al (2002), in an oven at 60ºC for 18 h. The yield in each plot was determined by harvesting all plants in two •: Start of fl owering. : Maturation.…”

“…The roots and other samples were dried at 60ºC until the weight became constant (for about 48 hr) in a forced-air circulation oven by the same method as reported by Izquierdo et al (2002), to obtain the dry weights. The oil and fatty acids contents of the seeds were measured using the same method as in Experiment 1.…”
