Name two laboratory tests used to assess treated seed quality.

• A. Tetrazolium test and vigor test.
• B. Germination test and accelerated aging test.
• C. Leaf chlorophyll content assay and root hair count.
• D. Protein assay and starch gel electrophoresis.

Answer: (B)

Assessing treated seed quality focuses on viability and vigor under controlled conditions. The germination test directly measures viability by showing what fraction of seeds can sprout under standard conditions, revealing whether the treatment has maintained the seed’s ability to begin growth. The accelerated aging test subjects seeds to high temperature and humidity to simulate aging, uncovering vigor and how well seeds hold up during storage or stressful field conditions. Together, these two tests give a practical picture of how treated seeds will perform: one indicates basic viability, the other predicts endurance and performance after storage. Other options involve more specialized or indirect measurements (like tissue viability staining or biochemical assays) that don’t directly capture whole-seed germination and vigor in a straightforward, widely used way, so they’re less representative of treated-seed quality.
