cqvip:[Objectives] This study was conducted to discuss the effect of chitin treatment on softening of Actinidia arguta Huanyou No. 1 as the test material.[Methods]Huanyou No. 1 was sprayed with chitin,and the changes of some physiological and biochemical indexes in fruit softening were investigated. [Results]Chitin treatment significantly improved single fruit weight,increased soluble solid content,but decreased titratable acid content and significantly reduced the content of cellulose and hemicellulose; and the chitin treatment significantly inhibited the breakdown of pectin,cellulose and hemicellulose,and inhibited the activities of PG enzyme and β-Gal enzyme. [Conclusions] Chitin spray treatment could increase the yield of A. arguta,and improve its quality and storage property.
