Chrysanthemum, var. No. 3 Indianapolis White, subjected continuously to atmospheres containing 1 -4 p.p.m. ethyiene, failed to initiate and develop flower buds under short-day conditions. The plants showed typical epinastic symptoms, shortening of internodes, thickening of stem and loss of apical dominance. The plants developed many short axillary shoots, each with a few small leaves. The top leaves on the plant became smaller and smaller and were less dissected than the controls.
