Conteúdo: | Physiological changes occur during seed storage that impair various functional elements and systems, reduce performance capabilities, and ultimately lead to germination failure. These changes are referred to as seed deterioration, an inexorable, progressive, irreversible process, the rate of which is influenced by inheritance, the quality of seeds as they enter storage, temperature, and seed moisture content/relative humidity. Problems associated with soybean seed storage are more difficult and severe than for most other kindas of seeds becaouse the seeds of modern cultivars are inherently short-lived. The evidence is very substantial that impairment of the membrane systems in seed is a fundamental event in the process of deterioration. This event leads to a loss os efficiency in respiration and biosynthesis, which in turn leads to a reduction in speed of germination and seedling growth, an increase in the susceptibility of the seed to stress, an increase in the incidence and severity of seedling abnormalities, and ultimately to loss of the capacity for germination. Deterioration and vigor are essentially antonymous. They represent the negative and positive aspects, respectively, of a seed or seed lot's physiological condition.
