Methods

Tetrazolium tests are conducted on a 200 seed sample. Soybean seeds are typically imbibed for 16 hours and then and stained in 1% Tetrazolium solution.

What is Reported

A percentage of viable seed (normal staining embryos and any dormant seeds).

Value of Results

Tetrazolium is a quick estimate of germination and can be useful in determining viability of hard seeds.  When seed has a fungal colonization, such as Fusarium or Phomopsis spp., the TZ test will best estimate a treated germination test.
