Variety traits
Helianthus annuus L.
Sunflower oil content is the crude fat content in seeds, which is a key indicator of their quality and market value. In modern hybrids, this value typically ranges from 40–56%.
In the reference 1 310 varieties crop Sunflower, where this is mentioned in the description.
To determine the oil content of sunflower, both laboratory methods, such as Soxhlet extraction and pulsed NMR spectroscopy, and rapid IR spectroscopy methods are used. The value is calculated as a percentage of the total seed mass, adjusted for moisture content, and a base level of 44–46% is typically established for market calculations.
Oil accumulation is significantly influenced by agrotechnical and climatic factors. Phosphate fertilizers contribute to higher oil content, whereas excess nitrogen, as well as drought and high temperatures during the seed-filling period, can reduce this indicator. Furthermore, harvest timing affects final oil content, as seed over-ripening leads to quality degradation and loss of seed mass.
