Grade 3645 papers are suitable for testing seeds with small white rootlets.

Grade 3236 papers are suitable for testing medium-large and coated seeds (e.g. sugar beet, fodder beet, grain, sunflower, rapeseed, mustard).

The better contrast of the color seed testing papers makes evaluation easier, particularly for seeds with fine white rootlets or under artificial light. This makes work easier, improves the results, and saves time. The dyes that we use have been thoroughly investigated and have no influence on the growth of the seeds.
