title: Lag-phases in phytochrome-mediated enzyme synthesis (PAL).
abstract: In experiments with the mustard seedling (Sinapis alba L.) it was confirmed that in the case of "secondary irradiation" induction of PAL by phytochrome is a very rapid process. The lag-phase after the onset of light is too brief to be detected. However, the data of other investigators, who found extended "secondary" lag-phases in their experimental material, can be imitated with the mustard seedling. We explain why these investigators were not able to eliminate the "secondary" lag-phase.
