Question: 1 / 400

What is the percent pure live seed of wheat seed with 92% germination and 94% purity?

86.5%

To determine the percent pure live seed (PLS) of wheat, the formula used is:

Percent PLS = (Germination % × Purity %) / 100.

In this scenario, the germination percentage is 92%, and the purity percentage is 94%. Plugging these values into the formula yields:

Percent PLS = (92 × 94) / 100 = 8648 / 100 = 86.48%.

This rounds to approximately 86.5%. Therefore, the correct answer reflects the calculation, indicating that roughly 86.5% of the seed is considered pure live seed. This measure is important as it helps farmers and agronomists evaluate the effective planting potential of the seed they are using.
