Culture of excised cotyledons in 6 × 10 ‐2 M sucrose reduces petiolar chlorophyll protein and RNA, inhibits CO 2 fixation and suppresses the development of root primordia. This syndrome is preceded by enhancement of ethylene production by sucrose, particularly in the light. Glucose also increases ethylene production and petiole senescence whereas 3‐O‐ethyl glucose does not.
