Warm Germ - Paper Towel
The warm germination test is the standard test used to assess viability of seed lots. The seed is germinated in nearly ideal conditions, and the result is the germination percentage reported on the seed tag of commercially sold seed, as required by the Nebraska State Seed Law. Ideal temperature, relative humidity and light vary depending upon the plant species being tested. The materials needed to conduct the warm germination test of large-seeded crop species, such as corn and soybean, are: wetted thick paper towel, wetted thin paper towel, a seed counter tray, and a container to hold the seed.
The germination chamber controls temperature, relative humidity (humidifier at bottom) and light.
