title: Phytochrome involvement in stimulation and alleviation of inhibition of plant growth by malformin.
abstract: Stimulation of stem elongation on green cuttings of Phaseolus aureus by malformin occurred only in red light and was specifically reversible by subsequent treatment with far red radiation. Inhibition of stem elongation of etiolated cuttings by malformin in the dark was alleviated by red light and was repeatedly reversible with far red irradiation. A direct or indirect effect of malformin on phytochrome action was suggested.
