Germination, Vigor, & Physical Purity

What is germination, vigor, & physical purity testing?

Germination, vigor and physical purity are three seed-quality characteristics targeted in standard seed tests for agronomic crops, flowers, herbs, vegetables, and grasses. These tests are critical for determining a seed lot’s performance in the field and/or greenhouse. Furthermore, U.S. seed labeling laws require that labels contain germination, physical purity, and noxious weed percentages.
