Abstract
Treatment of mature citrus fruit (Citrus sinensis) with ethylene induced rapid chlorophyll destruction, a rise in respiration, a release of free amino acids, an accumulation of reducing sugars, and an appearance of phenylalanine ammonia lyase activity. Gibberellin A(3) (GA(3)) and N(6)-benzyladenine (BA) opposed the effects of ethylene on chlorophyll, amino acids, and to a lesser extent, reducing sugar levels. The ethylene-induced respiratory rise was only slightly modified by GA(3) and BA. Phenylalanine ammonia lyase activity was not affected by GA(3).The antagonism between ethylene and the senescence-delaying regulators GA(3) and BA seems to operate mainly within the chloroplast, but might not be confined to this compartment. The accumulation of reducing sugars exhibits the antagonism although it is not apparently related to the chloroplast.
