Floral induction by night interruption of Fuchsia hybrida cv. Lord Byron, a quantitative long-day plant with decussate phyllotaxis and an indeterminate flowering habit, altered neither the rate of leaf initiation nor the rate of leaf expansion; nor did flower initiation and development change the vegetative growth of the plants. This was diagnosed using plastochron duration and plastochron ratio measurements before, during, and after a 10-day induction period. A comparison between indeterminate and determinate flowering is made using these two parameters.
