Wheat ( Triticum aestivum L.) seeds were stored in simulated conditions of four regions for 300 d. Changes of biochemical properties and electron microscope pictures demonstrated that unfavorable storage conditions caused serious internal deterioration and promoted the accumulation of unhealthy products in wheat seeds. Two hypotheses were proposed to explain the internal deterioration during storage. This work confirmed that the unfavorable storage conditions damaged enzymatic scavenging systems. As a result, without an effective scavenging system, serious internal deterioration occurred in wheat seeds. Atmospheric composition was adjusted to evaluate the potential of applying nitrogen atmosphere control in wheat storage. The results showed that 98% nitrogen gas in atmosphere effectively protected scavenging systems in wheat seeds and alleviate the internal deterioration.
