Abstract
Cheverry, J. L., Sy, M. O., Pouliquen, J. and Marcellin, P. 1988. Regulation by CO 2 of 1‐aminocyclopropane‐1‐carboxylic acid conversion to ethylene in climateric fruits. ‐ Physiol. Plant. 72: 535–540. A high CO 2 concentration (20%) at 20°C rapidly and strongly inhibited the development of the climacteric ethylene burst in apple ( Malus domestica Borkh. cv. Granny Smith) and avocado ( Persea americana Mill. cv. Fuerte) fruits and did not change 1‐aminocyclopropane‐l‐carboxylic acid (ACC) content. Treatment with 20% CO 2 markedly decreased ACC‐dependent ethylene biosynthesis at 20°C in climacteric pericarp tissues. It is suggested, therefore, that high CO 2 levels inhibit conversion of ACC to ethylene. Synthesis of the ethylene forming enzyme (EFE) was enhanced when intact preclimacteric apples or early climacteric avocados were pretreated for 40 h with 10 μ11 ‐1 ethylene. When CO 2 (20%) and ethylene were both applied, a reduced stimulatory effect of ethylene on EFE synthesis was observed. A high CO 2 concentration enhanced EFE acivity in excised tissues of apples and avocados incubated with ACC (2 m M ) and cycloheximide (1 m M ) or 2–5‐norbornadiene (5 ml 1 ‐1 ). In the autocatalytic process, 20% CO 2 antagonized the stimulation of EFE synthesis by ethylene, but promoted EFE activity.
