Abstract

Abstract: Using the fruit of different growing period of jujube （Ziziphus jujube Mill.） as materials,the activity of cell wall enzymes of cellulase（Cx-cellulase）, β-galactosidase（β-Gal）, pectin methylesterase（PME）, and polygalacturonase（PG） were observed and discussed the related to the jujube fruit growth processes. The results showed thatin the whole growth, Cx-cellulase was rised stablely, β-Gal reached maximum from full red stage to full ripe stage, PME reduced from half red stage to full red stage, and PG was rised in full ripe stage. It was speculated that Cx-cellulase was related to fruit enlargement of jujube, and it is one of the important substances of softening of jujube fruit. PME may be played a role in starting discolour, β-Gal and PG play a key role in the mature period of jujube fruit.

Key words: jujube（Ziziphus jujube Mill.）, fruit, process of growth, cell wall enzyme, enzyme activity
