Résumé

Freshly harvested early- and mid-season Bartlett (Williams Bon Chrétien) pears (Pyrus communis) were treated with ethylene (air plus 10 Pa C2H4) or air at 5, 10 and 20 °C for 24 and 48 h (experiment 1) and at 5 and 10 °C for 48, 72 and 96 h and at 20 °C for 24 h (experiment 2). Following the treatment, pears were transferred to 20 °C in air for ripening. Bartlett pears were evaluated for firmness, colour, respiration, ethylene production and activities of 1-amino-cyclopropane-1-carboxylic acid synthase and 1-amino-cyclopropane-1-carboxylic acid oxiase. Ethylene action was temperature dependent.
