PROBLEM TO BE SOLVED: To provide a method for blooming a nursery stock raised from seed, promoting phase transition, and rapidly inducing floral differentiation to lateral buds in a transient phase or a reproductive phase.SOLUTION: The method for blooming the nursery stock raised from seed includes sowing Prunus persica seeds subjected to germination promoting treatment, growing a seedling raised from seed until the seedling raised from seed reaches a transient phase or a reproductive phase without allowing natural dormancy, and performing adhesion treatment of a uniconazole solution or pouring or adhesion treatment of a paclobutrazol solution before a floral differentiation period after reaching the transient phase or the reproductive phase. The uniconazole concentration in the uniconazole solution or a paclobutrazol concentration in the paclobutrazol solution is preferably within the range of 50 to 500 ppm. Furthermore, it is preferable to perform root pruning treatment together with the adhesion treatment or the pouring treatment.COPYRIGHT: (C)2011,JPO&INPIT【課題】相転移を促進し、移行相又は生殖相にある側芽に速やかに花芽分化を誘導することができる実生苗木の開花方法を提供する。【解決手段】発芽促進処理されたハナモモの種子を播き、実生苗を自然休眠させることなく当該実生苗が移行相又は生殖相に達するまで生育させ、前記移行相又は生殖相に至った後で花芽分化期前にウニコナゾール液の付着処理又はパクロブトラゾール液の潅注若しくは付着処理を行う。このとき、ウニコナゾール液中のウニコナゾールの濃度又はパクロブトラゾール液中のパクロブトラゾールの濃度を50~500ppmの範囲内とすることが好ましい。また、付着処理又は潅注処理とともに断根処理を行うことが好ましい。【選択図】なし
