Enhanced ethylene synthesis in cold stored carnation flowers.

 

Storage of cut carnations (cv. White Sim) at 4 deg C resulted in the accumulation of N-malonyl-1-aminocyclopropane-1-carboxylic acid (MACC) in the petals and a concomitant increase in the activity of ACC oxidase. The senescence of carnations following removal from cold storage (for 5, 7 or 9 weeks) occurred earlier with a higher peak of ethylene production than in flowers which had not been stored at a low temperature. Accompanying this climacteric peak of ethylene production, there was an increase in 1-aminocyclopropane-1-carboxylic acid (ACC) and MACC. The increase in ACC and MACC content was higher in cold-stored flowers. In addition, ACC oxidase showed a peak associated with senescence, coinciding with the peak of ethylene production, and it was greater in flowers stored for longer periods.
