| 摘 要： | 利用(氧传感)Q2技术检测番茄种子经Gentle B、Safe B引发处理后的活力,结合25℃常温、35℃/10℃(昼/夜)温度逆境发芽试验,以评价Q2技术检测引发后种子活力的可行性。结果表明,番茄种子经引发后萌发启动时间(IMT)和理论萌发时间(RGT)缩短,萌发氧气消耗速率(OMR)增加,与发芽试验中发芽势、发芽指数反映的结果一致,说明利用Q2技术快速检测番茄种子引发后的活力是可行的。

| Abstract: | Effects of seed priming with Gentle B and Safe B on tomato（Lycopersicon esculentum Mill.）seed vigor were investigated by Q2（oxygen sensor）technology. Germination tests in common temperature（25 ℃）and temperature stresses（35 ℃/10 ℃）were conducted, so as to evaluate the feasibility of using Q2 technology to test seed vigor after priming. The results showed that both Gentle B and Safe B priming could improve seed vigor and Safe B priming showed more obvious effects. Primed seeds could shorten the increased metabolism time（IMT）and relative germination time（RGT）, increased oxygen metabolism rate（OMR）, which was accordant to germination energy and germination index. This result suggested that it was feasible to test the vigor of primed tomato seeds by Q2 technology. |
