Avocado (Persea americana Mill.) fruits were harvested at successive development stages during a period of 10 months. Ethylene production and respiration were determined during the post-harvest period.
Detached immature fruits were found to have a preclimacteric increase in ethylene production and respiration without any signs of ripening. In fruits larger than 20 g a second phase of climacteric ethylene production and respiration, associated with ripening, ensued.
The preclimacteric ethylene was produced mainly by the seed coat. It is suggested that the high ethylene production potential of the seed coat may serve as a means for inducing abscission in young fruits.
