Ethylene enhanced the degreening of intact radish cotyledons held in the dark for 36 h. Ethylene treatment (100 p.p.m.) caused a significant decrease in chlorophyll (Chl) content, and Chl b was degraded preferentially. No chlorophyllase activity was detected in the cotyledons but Chl a bleaching enzyme activity was detected; the enzyme required H2O2 and 2,4-dichlorophenol.
