The effects of temperature and humidity on bulb quality and sprouting after planting for spring-harvesting cultivation of Allium × wakegi Araki were investigated as compared with the conventional storage method by hanging under eaves. The cold storage of the bulbs at 0 or 5°C, humidity 70 to 90RH% from July reduced bulb deterioration and promoted sprouting after planting. Since control of humidity (70 to 90RH%) largely depends on the situation and condition of the precooling chamber, it is necessary to pay attention to practical use. In addition, the effect of the operation time of the dehumidifier in precooling chamber was investigated to maintain humidity 70 to 90 RH% suitable for seed bulbs of Allium × wakegi Araki. The possibility of using a storage for brown rice as a storage for bulbs of Allium × wakegi Araki was also investigated. The operation time of commercial dehumidifier (dehumidification capacity 17.5 L・day-1 , power consumption 400 W at 27℃ ) for 15 to 45 minutes per hour in a pre-cooling chamber was suitable for storing bulbs of Allium × wakegi Araki. In addition, a storage for brown rice by setting the temperature to 3 to 5 ℃ and high humidity mode was able to adapt to storage for bulbs of Allium × wakegi Araki.
