Warm Standard Germination
Test Details
Seeds are briefly exposed to fast green solution (or another type of stain if green seed treatment is present) and then excess solution is washed off (stain stays in the cracks). Damage is classified as Light (damage to base of seed or small areas away from the embryo), Medium (damage extending along either side of the embryo) or Severe (damage to seed over the embryo). The test is most useful in setting equipment in seed conditioning facilities so as to maximize output while minimizing damage from machinery.
