Description

Effect of time zone of night break treatment for three hours, equivalent to long day (15 hour day length) treatment, on bulb hypertrophy was investigated in seed bulb production for early summer-harvesting cultivation by planting from March to May of Allium × wakegi Araki. It was found that bulb hypertrophy was promoted by night break treatment for 3 hours from 9 hours after twilight after sunset, comparing to that at the center of the dark period, and planting the treated bulbs consequently gives vigorous growth for early summer-harvesting cultivation.
