This study investigated the Co_2 and C_2H_4 production rates, titratable acidity(TA), sugar content and invertase activity of kiwifruits in order to find a suitable harvest index other than soluble solid(SS) content and firmness. Kiwifruit exhibited a wide variability in ripening pattern. The pronounced increase in C_2H_4 production rates did not coincide with climacteric rise hence the CO_2 and C_2H_4 evolved were not used as the indication of the ripening. These results seem to indicate that kiwifrut has a very weak climacteric type of respiration pattern. TA, sugar content and invertase activity can not be used as the harvest and ripening indices for kiwifruit due to the variations observed. The changes in starch contents observed in the previous study appear to be a better guide of maturity than TA, sugar content and invertase activity.
