It is important to avoid delay of growing in winter and to promote tillering and division of bulbs for increasing number of bulbs in the seed bulb production for spring-harvesting cultivation of Allium × wakegi Araki. Effects of temperature and starting time of heating on growth and bulb hypertrophy were examined. Higher temperature and earlier heat treatments resulted better growth and more number of bulbs. It is practically preferred that heating should be started before the beginning of December and minimum temperature should be more than 2 ℃ in consideration of the cost of the fuel oil.
