Regulation of respiration in apple, avocado and Citrus orange fruit.

 

Anatomical, physiological and biochemical features which regulate respiration were examined in apple, avocado and orange fruits. At harvest, the number of stomata or lenticels ranged from 1/mm2 in apples to 3-5/mm2 in avocados and 50-75/mm2 in oranges. The slowest respiration rate was observed in apples and the fastest in avocados. Intercellular space volumes ranged from 5 to 25% in the 3 fruits. Mitochondrial and seed respiration produced intercellular CO2 concentrations of between 2 and 20%. A large proportion of the CO2 respired by mitochondria was refixed within the fruits by beta -carboxylation of the enzyme phosphoenolpyruvate carboxylase and recycled into the carbon and organic acid metabolism.
