SA231 - Corn Quality Lecture
Understanding Corn Germ and Vigor Tests
This webinar will walk the participant through the primary standard germination and vigor tests used to evaluate seed corn quality. The principles of each test will be discussed, along with baseline quality levels and interactions that may occur. Two standard germination test methods will be discussed, including the tray method on crepe cellulose paper and the sand method. Also included is a review of seedling morphology and how tissue structures are influenced by variables in the germination regime. Four vigor tests will also be reviewed, including the tray cold, saturated cold, accelerated aging and the electrical conductivity.
