    Seed Vigor Testing. The basic objective of seed vigor testing is to provide a precise identification of important differences in physiological potential among seed lots of commercial value, mostly those of similar germination percentage, aiming to identify lots of higher probability to perform well after sowing and/or during storage. It must be A germination test does not test seed vigor. Seed vigor may decrease even as germination rate remains constant. To maintain high vigor and germination, store seeds at low, constant temperatures with very low humidity. Some species or varieties simply don’t have the same storage life as others, which is why regular germination testing is so
