Germination and vigor

Why is germination important?

Viable seeds will germinate if they are placed under suitable conditions of moisture, temperature and oxygen. Poor harvesting and storage conditions can result in low seed quality, however, issues like cleaning, processing, shipping, disease, insects and environmental influences also have a high impact on the germination quality.

It is important to detect the germination capacity of a seed lot fast and efficiently in order to be able to proceed quickly with further seed handling. This is done smoothly with the VideometerLab where the multispectral imaging results will show you the percentage of viable seeds in your lot.

An example of seed germination measurement in the malting industry: acrospire assessment

3 simple steps for detection of chitting %

Germination process - chitting is discovered with multispectral imaging in the VideometerLab

  1. Put the grains in a Petri dish (single kernels)
  2. Place the Petri dish in the VideometerLab
  3. Activate measurement
-> Results within 20 seconds
  • Grains without any sprout will be marked in a red rectangle and grains with sprouts will be marked with a green rectangle in the output image.
  • The number of chitted kernels in % will be calculated.

 

Seed vigor testing

Seed vigor defines the activity and performance of a seed. The size and health of the seed determine the growth rate. When using multispectral imaging measurement with the VideometerLab you can quickly determine seed vigor properties.

Seed vigor testing

Measurements of seed vigor by movement registration. Seeds placed in water and images acquired with 12 hours interval. Difference image used to measure magnitude of movement. Above the line are viable seeds and below are non-viable seeds.
