Abstract: | Abstract. Anthocyanin biosynthesis in red cabbage seedlings has been shown to be under a red/far-red (R/FR) reversible phytochrome control. The 'escape' of anthocyanin synthesis from FR photoreversibility occurred between 12 and 20 h. However, a similarity exists between the escape curve and the temporal change in sensitivity to FR alone, which suggests that some of the 'escape' may be due to the promotive effect of FR. Some escape times may not therefore be a true measure of the duration of Pfr action, contrary to the traditional view. |
