Accelerated aging is SoDak’s recommended vigor test for soybeans. Seed is aged in a water jacketed chamber for 72 hours at 41C in a high humidity regime. After aging seed is placed on crepe cellulose paper and covered with sand. Germination is evaluated 7 days after aging. Cold testing is available.

What is Reported

Percentage of normal seedlings after aging is reported. Fungal and physical damage notes may be noted.

Value of Results

A value within 15% of standard germination is considered strong, 16-30% difference is considered moderate and >30% difference is questionable. Cold testing soybeans in not recommended due to seed moisture migration.
