[The effect of physiologically active compounds on the production of ethylene and the activity of polygalacturonase inhibiting protein in fruits].

The treatment of apple and banana fruits with 2-CEFA and ethacyde induced the production of ethylene and accelerated the ripening and accumulation of ACC in apple fruits. Inhibitors AOA, AVG, and CoCl2 acted at the different steps of ethylene biosynthesis, inhibited the physiological aging process and increased storage longevity. Treatment with astaxantine and BOA delayed the pick of ethylene production by fruits.
