Abstract: Two stages appear during storage softening in Dongzao fruit.It soften slowly in the early stage but quickly in the later stage.PG activity rises in the last storage stage.While Cx-cellulase activity changes are similar to that of PG.PME activity peak appeares prior to the stage of fast softening and senescence,and possibly relates to the startup of fast softening and senescence.

Key words: polygalacturonase(PG), pectinmethylesteras(PME), Cx-cellulase
