Plants kept under short days conditions were induced for flowering for various durations by long day conditions (LD duration, in days). The number of floral buds at the given developmental stage amongst the five oldest flowers not subtended by a leaf was recorded in 10 plants.
S2, S3, S4-5, S6+, average number of floral buds at stage 2, 3, 4 or 5, and 6 or more per apex. Floral stages defined by Smyth et al.(1990).
Deduced as the total number of floral meristems minus total of S6+ to S2 stages.
