Solutions for physical seed purity
Improving overall yield and quality
Physical seed purity refers to the percentage of pure seeds of the desired crop variety in a seed lot, free from contaminants such as seeds of other crops, weed seeds, inert matter (like dirt, stones, and broken seeds), and other foreign materials.
It is a crucial factor in seed quality assessment, ensuring that breeders get high-quality seeds that lead to uniform germination and optimal crop yield. Physical purity is typically expressed as a percentage, with higher values indicating better seed quality.
For example, if a seed sample consists of 98% pure wheat seeds, 1% weed seeds, and 1% inert matter, the physical purity of that sample is 98%.
Maintaining high physical seed purity is important for:
✔ Ensuring uniform crop growth
✔ Preventing weed infestation
✔ Avoiding contamination from unwanted crop varieties
✔ Improving overall yield and quality
All devices from MARViTECH are equipped with advanced technology to filter out impurities and detect broken seeds. Additionally, they can identify foreign seeds and weeds based on their shape, ensuring optimal seed purity and quality.
With MARViN VisionLine, even more measurement parameters are available—such as object brightness, color, and discoloration—allowing for even greater precision in seed purity analysis.
While purity determination with a measurement device is not the same as a physical (human) purity test, it quantifies similar characteristics of a seed lot.
This makes it particularly useful for:
Efficiently estimating purity in unregulated seed analysis
Supporting or serving as a pre-analysis for
ISTA-regulated physical purity testing
Additionally, the system generates and stores detailed phenotypic data
for each individual seed, including:
Size (length, width, area), shape, and color shades.
