Where is seed quality usually highest when stored?

1. In high temperatures and humidity

2. In low temperatures and humidity

3. At room temperature

4. In dry, warm conditions

The correct answer is: In low temperatures and humidity

Seed quality is typically highest when stored in conditions of low temperatures and humidity. This is because seeds are living organisms that can remain dormant but still require proper environmental conditions to maintain their viability. High temperatures and humidity levels can lead to accelerated metabolic rates, which increases respiration and can ultimately reduce seed vigor and longevity. Storing seeds in a low-temperature environment slows down these metabolic processes, helping to preserve their energy reserves and prevent deterioration. Low humidity is equally important as moisture can foster mold growth and lead to seed rot or germination before planting. Hence, maintaining low temperatures and humidity levels significantly enhances the seed's preservation by minimizing the risk of biochemical degradation and pathogen invasion, ensuring higher germination rates and better crop performance when planted.
