Abstract
Apricots of cv.
Bebecou were kept at 0°, 7° and 25°C with 0, 100, or 1000 ppm propylene.
Softening was fast at 25°C with flesh firmness decreasing from 32N to 10N in 6 days.
Apricots kept at 7°C lost only 4N flesh firmness after 20 days of storage, while those kept at 0°C remained relatively hard (27N) after 36 days.
At these low temperatures after prolonged storage apricots were unsalable due to internal breakdown.
Soluble solids content increased slightly after a few days in storage and decreased thereafter due to ripening and possibly due to internal breakdown.
Ethylene production was high at 25°C and minimal at 0°C. There was no autocatalytic ethylene production in the absence of propylene.
One hundred ppm propylene caused autocatalytic ethylene production and accelerated softening in apricots kept at 25°C but not at the ones kept at 0° or 7°C. One thousand ppm propylene caused even more autocatalytic ethylene production and faster softening at 25°C.
