Abstract
Changes in the level of 1-aminocyclopropane-1-carboxylic acid (ACC) were compared to ethylene production during fruit ripening of avocado (Persea americana Mill.) banana (Musa sapientum L.) and tomato (Lycopersicon esculentum Mill.). Preclimacteric tissues contained less than 0.1 nmol/g of ACC in all tissues. In avocado, the level of ACC increased to 45 nmol/g in the later stage of the climacteric rise, then decreased to 5 nmol/g, and later increased to over 100 nmol/g in overripe fruit. In banana ACC increased to 5 nmol/g during the climacteric, decreased to 2 nmol/g several days after the climacteric peak, and increased up to 5 nmol/g in overripe fruit. Levels of ACC in tomato ranged from 0.1 to 10 nmol/g and were significantly correlated with ethylene production rates in all but overripe fruits. The correlation between the ACC content and the production of ethylene is discussed.
