Comparative storage behaviour of the pods from a large-fruiting and small-fruiting okra cultivar

Weight loss of pods of small-fruiting okra cv. Boyiatiou stored at 10°C was higher than that of large-fruiting cv. Clemson spineless. Enclosure in plastic film reduced weight loss, but in Clemson spineless caused surface discoloration. In both cultivars, respiration and ethylene evolution increased during storage, while firmness and colour intensity decreased. Subsequent transfer of pods to room temperature (22°C) for three days increased loss of weight, firmness and colour, especially if the film was removed. We conclude that the small pods of cv. Boyiatiou may only be stored satisfactorily at 10°C if enclosed in plastic film, and for a period of > 5 days pods should not be subsequently subjected to shelf life at 22°C. The larger pods of Clemson spineless, however, store better in air at 10°C. Thus, recommendations for storage should take into account cultivar and pod size.
