Abstract
It was shown that stem elongation in A. frutescens is controlled by ph ytochrome. Both red and blue light reversed the effect of far red. Inv estigations of the kinetics showed that plants were not able to react on far red given in the day-time, if antistimulation appeared at the e nd of the main light period. Even if there was a delay in stimulation by red or blue light application stem elongation was prevented. A ligh ting of 15 minutes was sufficient for a positive reaction.
