A method of regulating the emergence of flower stalks and flowering of Phalaenopsis ‘Ensyu’ × Phal. ‘White Dream’ (Exp. 1 and Exp. 2) and Phal. ‘Miki Saito’ × Phal. ‘Jenco Arctic Mass’ (Exp. 3) was investigated.
When the emerged flower stalks were removed at their bases, new flower stalks always emerged and their flowers bloomed after 3.5 months (Exp. 1). If the flower buds were continuously removed when pea-sized, new flower stalks did not emerge for about 10 months (Exp. 2). If the disbudded flower stalks were excised at their bases early in April or early in November, new flower stalks always emerged and their flowers bloomed after 120-130 days (Exp. 3).
These results indicated that the timing of flower stalk emergence and flowering in Phalaenopsis could be regulated by a combination of flower bud removal and flower stalk excision.
