| | Extending the period in SD until 10 or
12 weeks after seeding gave a progressive delay and finally no difference was observed
between constant SD conditions and transfer 14 weeks after seeding. Compared to a low
light integral (LL), a high integral (HL) enhanced the onset of floral primordia by at least 8
days and the delay in relation to the SD control was therefore, at least 18 days. A transfer to
HL up to 10 weeks after seeding promoted the onset strongly, while SD conditions up to
transfer at 12 and 14 weeks clearly delayed the process. Continuous SD delayed the
formation of the floral organs slightly compared to LL and HL, while no significant
difference between the two LD conditions (Fig. 2).
