National Seed Testing Station (SNES)

The SNES is the National Reference Laboratory in France for seed quality analysis for seed import and export. The station contributes to the implementation of seed certification regulations and facilitates national and international seed trade.

Missions

The SNES is the National Reference Laboratory in France for seed quality analysis for seed import and export. The station contributes to the implementation of seed certification regulations and facilitates national and international seed trade.

It carries out a range of regulatory activities:

  • carrying out official seed analysis and testing for all species
  • providing services for private companies in the seed sector
  • monitoring the network of seed testing laboratories in France
  • innovating, developing, and validating testing methods
  • representing France in international technical bodies to promote France’s position and expertise.

Analyses

Seed quality testing is one of GEVES’s primary missions. Tests include various analyses which are carried out at the National Seed Testing Station.

Physical quality is determined by the following analyses:

  • Specific purity
  • Determination of foreign species
  • Moisture content
  • Micro-cleaning
  • Radiography
  • Dust quantification
  • Cytometry
  • Botany

 

 

Germination quality is measured by:

  • Evaluation of germination ability
  • Vigour tests
  • Viability tests

 

 

Seed health is determined by testing:

  • Seed health state
  • Selectivity and effectiveness of phyto-sanitary treatments
