Pomegranate (Punica Granatum L. 'Wonderful') fruit reached horticultural maturityfor commercial harverst when the soluble solid contents (SSC) attained a fairly constant level of 15%. The level of titratable acidity (TA) varied from one location to another and from one year to the next but also generally remained stable at the same time that the SSC reached  15%. After harvest, there was no further change in either SSC or TA at 20°C, but redness of the juice continued to increase in intensity up to and after harvest. The respiration patternof the mature fruit was of the nonclimacteric type, with only traces of ethylene evolved on occasion. Ethylene traetment of the fruit caused a rapid transient rise in the CO² evolutionbut no changes in SSC, TA, and fruit or juice color. A pseudo-climacteric pattern of respiration was found in very young immature fruit. The respiration rate of dehisced arils paralleled that of the intact fruit, but there was no response to exogenous ethylene treatment. Ethylene evidently stimulated the CO² output only of the fruit rind.
