Seed quality is usually highest for seed stored under which conditions?

Seed quality is highest when stored under low temperature and low humidity conditions because these factors significantly slow down the metabolic processes that can lead to seed deterioration. In cooler temperatures, the respiration rate of seeds decreases, reducing the consumption of stored energy reserves and prolonging viability. Low humidity prevents the seeds from absorbing excess moisture, which can lead to mold growth, fungal infections, or germination before planting.

By keeping seeds in an environment that is both cool and dry, you ensure a stable storage condition that helps maintain the genetic integrity and vigor of the seeds. This allows for a greater likelihood of successful germination and healthy plant development when the seeds are eventually planted. Proper storage conditions are essential for preserving seed longevity and performance, making the combination of low temperature and low humidity the optimal choice for seed storage.
