シンテッポウユリ'早池峰'の暗期中断と加温による4〜5月収穫作型開発の検討(栽培管理・作型)  [in Japanese] Acceleration of Flowering by Night Break and Heating Treatment for Harvesting in April and May in Lilium×Foromolongi. cv. Hayachine(Crop Production & Cropping Type)  [in Japanese]

シンテッポウユリ'早池峰'の4月〜5月出荷作型を確立するため, '早池峰'の暗期中断加温の効果を検討した.1. '早池峰'を10月に定植して暗期中断加温栽培することで4月中旬, 無加温栽培で5月下旬に開花した.2. 定植時期は9月下旬〜10月中旬が早く開花し, 品質が良好であった.3. 暗期中断開始日を遅くしても開花は遅延せず, 切り花品質は維持された.

To harvest Lilium×formolongi cv. Hayachine flowers in April and May, effects of night break and heating treatement were examined. The flowering time of 'Hayatine' lily was accelerated to the middle of April by nightbreak and heating treatment, but to late May by night-break treatment alone. When liles were planted in September and October, flowering time was earlier and the resulting quality of cut flowers was better, compared to those planted at other times. There was little difference in the quality of cut flowers regardless of the starting time of the night break treatment.
