With main photoperiods of red or white light, the inhibition of flowering in Lemna perpusilla 6746 caused by interruptions of the night with red light cannot be reversed by far-red light, since far-red light itself is highly inhibitory. However, with a main photoperiod of blue light, far-red light is much less inhibitory and partially reverses the effect of red night-interruptions. If the main blue photoperiod is terminated by a brief red exposure, reversibility is abolished, as the far-red… CONTINUE READING
