Root growth rate was studied in Lemna gibba L. (strains Gl and G3) and L. minor L. in relation to low energy red and far‐red light treatments. Far‐red treatments inhibited growth rate; inhibition was abolished upon subsequent treatment with red light. These effects can be observed after an 18‐hr growth period. This red/far‐red photoreversible response suggests that root growth in L. gibba L. and L. minor L. is under phytochrome control.
