What is seed viability and how is it tested?

• A. The ability of seeds to germinate under proper conditions; tested with a germination test following standard procedures.
• B. Seed viability is a measure of seed color.
• C. Seed viability is the moisture content only.
• D. Seed viability refers to storage duration.

Answer: (A)

Seed viability is the ability of seeds to germinate and develop into normal seedlings when placed under proper moisture, temperature, and light conditions. It is tested with a germination test conducted according to standard procedures, which means evaluating a representative sample of seeds under controlled conditions and counting how many sprout within a defined period. The result is usually expressed as a germination percentage, indicating how many seeds are likely to establish when planted. Other options miss what viability truly measures: seed color has no bearing on germination, moisture content alone doesn’t determine viability though it affects it, and storage duration relates to how long seeds can be kept rather than their ability to germinate.
