摘　　要：以晋农207、农大2322个小麦品种为材料,测定了种子经高温高湿老化处理后的发芽指标、种子活力、电导率的变化。结果表明,高温((54±1)℃)、高湿(相对湿度100%)、密闭老化处理24h后,晋农207、农大232多数发芽指标下降,种子活力降低,而种子的相对电导率升高。2个小麦品种耐老化能力存在差异,晋农207比农大232相对耐高温老化。Taking the wheat Jinnong 207 and Nongda 232 two varieties as the material, we had the change of the seed＇ s germination indexes, the vigor and electrical conductivity in the ageing disposal studied. The result indicated that under high temperature （54±1）℃ , airtight condition（ 100% relative humidity）, after the aging disposal,th,, majority of two varieties seeds germination indexes declined. The vigor of seeds reduced and the electrical conductivity declined too. The result also demonstrates that Jinnong 207 could live batter in the environment of high-temperature than Nongda 232.
