Variety traits
Helianthus annuus L.
An important indicator of sunflower seed size and plumpness, used to calculate seeding rates and assess seed quality.
In the reference 443 varieties crop Sunflower, where this is mentioned in the description.
For standard sunflower varieties, the standard 1000-seed weight is at least 50-60 g, while for large-seeded varieties, this figure reaches 60 g or more. The value is determined at the actual moisture content of the seed material using laboratory scales.
Large seeds possess an increased supply of nutrients, which promotes the development of a more robust root system and improves field emergence. This indicator is used to convert the target plant stand density into a weight-based seeding rate in kilograms per hectare.
There is a negative correlation between the number of seeds in a head and their weight. Agro-climatic conditions, the level of mineral nutrition, and the phytosanitary state of the crops have a significant influence on the formation of this indicator, determining the final plumpness of the seeds.
