Abstract
Red light (660 nm) break which cancels the floral inductive effect of the dark period brought about a transitional rise in the level of free IAA in the shoot ofChenopodium rubrum. The higher content of IAA was then found in treated plants at the beginning of the following photoperiod, too. The red light treatment did not change the phase of endogenous rhythm fluctuations of free IAA.
