以黄麻子品种马铃薯为试材,研究了饱和碘蒸气处理对已过休眠期的马铃薯在货架期发芽及生理指标的影响。结果表明:已过休眠期的马铃薯采用常温饱和碘蒸气处理6d后,能显著抑制发芽,有效保持块茎的可溶性固形物和硬度,降低块茎的呼吸速率和减缓相对电导率的升高,抑制块茎多酚氧化酶(PPO)、过氧化物酶(POD)及苯丙氨酸解氨酶(PAL)的活性。

Huangmazi potatoes were used as raw materials and effects on sprouting inhibition and physiological properties of dormancy-breaking potato tubers by the treatment of iodine vapor during shelf-life were studied. The result showed that potato tubers which exposed to iodine-saturated vapor for 6 days could inhibit the sprouting and maintain the soluble solids content and hardness effectively. It could also reduce the tubers respiration intensity,slowed down the rise of the relative conductive rate,inhibit the activities of polypenoloxidase( PPO),peroxidase( POD) and phenylalanine ammonialyase( PAL).
