Germination Test Papers

These paper grades satisfy the requirements for the determination of germination capability according to ISTA (International Seed Testing Association) and is ideal for ensuring optimal moisture content for the most diverse types of seeds and germination forms.

The pH ranges between 6.0 and 7.5, it is wet-strengthened and the special structure prevents fine seed roots from growing through the paper. The colored papers are produced with dyes that do not influence the growth of roots. These papers are mainly used to count more easily very fine and white roots.
