Fruits of the pear cultivar d'Anjou [Beurred'Anjou] were harvested at maturity levels of 66.7 and 60.0 N firmness from mature trees in Oregon, USA. The fruits were exposed to ethylene for 24, 48, 72 or 96 h. Ethylene levels were adjusted to 400 ppm at the beginning of each 24 h interval so that the level was about 100 ppm at the end of each 24-h period. The fruits were stored at -1 deg C for 2, 4, 6 or 8 weeks. Ethylene treatment at both stages of maturity for 96 h caused the fruits to soften and ripen normally in 7 days at 20 deg C after 2, 4 or 6 weeks' storage. Little softening was found at day 0 of ripening after ethylene treatment for 24 or 48 h except for the 60-N fruits after storage for 6 or 8 weeks. No differences were found between treated and control fruits after 8 weeks' storage and 7 days' ripening.
