Hypoxic acclimation prevents avocado mesocarp injury caused by subsequent exposure to extreme low oxygen atmospheres.

Avocado (Persea americana cv. Hass) fruits, preclimacteric and ripening, were either hypoxically pretreated (HPT, 3% O2 for 24 h) or exposed directly to 1 and 0.25% O2 for 1-3 days (NHPT) at 20 deg C. Low O2 treatments resulted in fruit maintaining higher flesh firmness. Hypoxic acclimatization of preclimacteric and ripening avocado fruit increased their tolerance to subsequent 0.25 and 1% O2 levels, as assessed by visual quality attributes when the fruits were exposed to air. Hypoxic pre-treatment also produced a stronger expression of the anaerobically induced ADH isoenzymes than in NHPT avocado fruits that were subjected directly to 1 and 0.25% O2 for 1-3 days at 20 deg C. Thus, acclimatization of avocado fruit to hypoxia resulted in a beneficial increase in tolerance to subsequent ultra-low O2 treatments.
