Abstract
Gibberellin A3 (GA3) stimulated flowering when it was applied to the shoot apex of seedlings of Pharbitis nil, dwarf strain Kidachi; but, not when it was applied to the cotyledons. GA3 applied to the plumule before or shortly after the start of an inductive dark period promoted both flowering and shoot elongation; but, the later the time of application during the dark period less the promotion of flowering, although marked promotion of shoot elongation always took place. The variation with time in the response of flowering to GA3 indicates that early floral processes at the apex are stimulated by GA3, but that subsequent processes are insensitive to it. The early processes of floral stimulus produced by a 16 hr inductive dark period probably are completed within 20 hr at 28°C after the end of the dark period. At low temperatures, such as 15 and 20°C, early floral processes continued for more than 40 hr. When cotyledons were removed at various times, the export of the floral stimulus to the shoot apex was apparent within hours of the generation of the floral stimulus in the cotyledons, which started with the passage of the critical 9-hr dark period.
