Seed Viability and Factors Affecting Seed Storage

For most seed technologists and commercial seedmen, viability means that a seed is capable of germinating and producing normal seedlings. Viability denotes the degree to which a seed is alive, metabolically active and posses enzymes capable of catalyzing metabolic reactions needed for germination and seedling growth. This meaning deals with tissue viability as well as viability of the entire seed. Seed viability is probably highest at the time of physiological maturity though environmental conditions on the apparent plant may not permit germination. After physiological maturity, the viability of seed gradually declines.
