Germination Test Papers
•Brochure: Sartorius Filter Papers
These paper grades are ideal for ensuring an optimal moisture content for the most diverse types of seeds and germination forms. They feature excellent wet strength, and their special structure prevents fine seed roots from growing through. These filter papers can be supplied in customized shapes and sizes for testing seeds according to ISTA (International Seed Test Association). They are available in different formats: paper strip formats with a predefined number of pleats according to NEEB and the Copenhagen tank system (Jacobsen), for instance, for testing beet seeds; filter discs or rectangles for testing seeds in petri dishes (osmosis test) or on top of paper, such as for testing grass or other types of small seeds; unpleated strips to form rolls from either a creped, plain or polyethylene-coated paper for testing the germination capability according to the "Vienna roll method", e.g., grain or pea seeds. See also the grades 4b, 6, 6 S/N, C 140.
PP ("Pleated Paper") Method
The pleated paper is placed in a box, the seeds are distributed among the folds of the pleated paper and covered with a wrapping strip to keep the seeds moist. Typically, the pleated papers have 50 double folds that are 20 mm in depth; usually, 2 seeds are placed in each fold. Both white and gray papers are available. Colored paper makes it easier to count white seed species.
