Flowering Time of Vernalized and Nonvernalized C24 and flf-1 Plants
| Plants | Length of Vernalizationa | ||
|---|---|---|---|
| 0 Weeks | 4 Weeks | 8 Weeks | |
| C24 (FLF/FLF) | 25.2 ± 0.2 | 13.6 ± 0.3 | –b |
| FLF/flf-1 | 71.4 ± 1.2 | 39.3 ± 3.7 | 20.2 ± 0.9 |
| flf-1/flf-1 | >150 | 100.8 ± 10.7 | 17.6 ± 1.3 |
↵a Twenty seeds of the FLF/flf-1 and flf-1/flf-1 mutant and wild-type C24 were grown aseptically on Murashige and Skoog media in test tubes and exposed to 4°C for either 4 or 8 weeks. Nonvernalized plants were grown in soil (20 plants per 20-cm pot). All plants were then grown at 23°C under fluorescent lights (16 hr of light and 8 hr of dark). The data are presented as the average number of days (±se) until stem elongation and exclude the period of vernalization.
