The main parameters for measuring and describing seed quality are germination percentage, including warm germination, cool germination (or vigor) tests, mechanical damage, and foreign material. The standard ("warm) germination test is conducted at an alternating termperature regime of 86 and 68 F, while the "cool germ" germ or vigor test employs a constant temperature of 64 F. Other analytical tools for measuring seed soundness and viability include the tetrazoleum test, the accelerated aging test, and a short term germination test.
