Studies on the ethylene production, polygalacturonase and beta -galactosidase activities of apple and pear fruits during storage.

Six apple and 6 pear [Pyrus pyrifolia] cultivars with different maturity times (early, mid- and late season), representing the main cultivars of Korea, were used to study the physical and biochemical changes associated with ripening. The apple cultivars Spur Earliblaze and Tsugaru (early), Jonathan and Starkrimson (mid-season) and Mutsu and Fuji (late), together with the pear cultivars Shinsu and Hangsu (early), Changshiprang and Shingo (mid-season) and Kumchonchu and Mansamgil (late) were used. Fruits were stored at 15 deg C. The pattern and extent of ethylene evolution varied between cultivars and the activities of the cell wall digesting enzymes polygalacturonase and beta -galactosidase followed a similar trend to ethylene evolution in both apple and P. pyrifolia fruits.
