Variety traits
Helianthus annuus L.
The test weight of sunflower seeds represents the bulk density of seeds, measured in g/l, and serves as an indicator of seed plumpness, biological maturity, and oil content.
In the reference 12 varieties crop Sunflower, where this is mentioned in the description.
For sunflowers, test weight is a physical characteristic reflecting the mass of seeds within a fixed volume. High test weight values typically indicate dense, well-filled seeds, which often correlate with higher oil content. Low values often indicate crop immaturity or the negative impact of external factors during the growing season.
Measurement is conducted using a one-liter grain scale after pre-cleaning the sample of foreign matter, with results significantly influenced by moisture content, seed temperature, and flowability. Unlike cereal crops, there are no rigid universal standards for sunflower test weight, as this parameter is highly dependent on the breeding characteristics of specific hybrids and seasonal conditions.
