Kiwifruits at 3 stages of ripening were stored at 3°C for 4 weeks to study the effect of cold storage on ethylene production and fruit quality. Samples taken weekly were analyzed for firmness, TSS, acidity, tissue chlorophyll and carbohydrate contents. Fruits at early stage of ripening (hard) produced less ethylene than fruits at late ripening stage (soft). Fruit quality attributes vary significantly among the different ripening stages and storage intervals.
