Stimulation by Ethylene of Chlorophyll Biosynthesis in Dark-grown Cucumber Cotyledons 1

PMCID: PMC366151  PMID: 16658183

Abstract

Five-day-old etiolated cucumber (Cucumis sativus L. var. Alpha Green) cotyledons produced more chlorophyll over a 4-hour illumination period after a prolonged exposure (12 to 72 hours) in the dark to ethylene concentrations ranging from 0.1 to 10 μl/l. Intact seedlings and excised cotyledons responded in the same way to this treatment. This effect does not involve a shortening of the lag phase of chlorophyll accumulation. Exposure of cotyledons to ethylene during the illumination period did not produce the same stimulatory effect on chlorophyll synthesis and, under certain conditions, chlorophyll synthesis was slightly inhibited by exposure to ethylene in the light.
