Effect of anaerobiosis on aspects of avocado fruit ripening.

 

Avocado cv. Fuerte fruits were treated with ethanol vapour (0.5%) or nitrogen gas (97%) for 40 h and stored at 17 deg C for 7 days. Fruit softening was retarded by nitrogen or ethanol treatment compared with controls. Ethanol treatment stimulated carbon dioxide production. The onset of the increase in ethylene production with ripening was delayed in the nitrogen-treated fruits. Both treatments increased pyruvate decarboxylase activity compared with controls, but alcohol dehydrogenase activity was only stimulated by the nitrogen treatment. The activity of the cell-wall-degrading enzyme polygalacturonase 7 days after treatment was 30% lower in nitrogen- and ethanol-treated fruits than in controls. At the same time, endoglucanase activity was also slightly reduced in both treatments.
