Soybean Tetrazolium Test
Soybeans showing staining from Tetrazolium testing
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.
Agronomically Accurate Seed Testing Results
SoDak Lab's goal is to deliver fast, accurate, and diagnostic seed testing services.
