Abstract
おどり仕立てポットハボタンの仕立て枝術の開発を目的として,ハボタンのポット栽培における摘心時期,摘心強度,摘心時の摘葉枚数,切除する葉の部位の違いおよび品種が草姿に及ぼす影響について検討した.'初夢'を供試し,7月上旬に播種した場合,強摘心することで,分枝位置が低く,鉢上げ4週間目に摘心することで,側枝長が短くなり,コンパクトな草姿となった.さらに,摘心時に葉身と葉柄を含む全葉を摘心後の上位葉位から3枚摘葉することで,側枝数が3本程度となることが明らかとなった.摘葉により側枝数の増加が認められた品種は'駿河の初日','冬紅','初紅'および'初夢'の4品種であった.
The effects of decapitation and defoliation just after pinching on the plant form were examined in order to develop methods of inducing branching in flowering cabbage (Brassica oleracea L. Acephala Group) with three lateral branches for bedding plants. When 'Hatsuyume' was sown in early July, hard pinching at potting after four weeks caused the plant form of flowering cabbage to become more compact. It was clear that removing the upper three leaves just after pinching effectively produced branches from axillary buds, especially in 'Suruga no hatsuhi', 'Fuyubeni', 'Hatsubeni' and 'Hatsuyume'.
