Abstract

Abstract: In order to reveal the effect of girdling on ‘Dongzao’ fruit quality, the main trunk of ‘Dongzao’ tree was ringed at the flowering stage, and with the unringed tree used as CK, the fruit quality indexes of ‘Dongzao after girdling treatment’and ‘Dongzao without girdling treatment’ were measured respectively at the mature stage. After the comprehensive analysis of fruit quality through the calculation of membership function, the results showed: the single fruit weight, fruit hardness, fruit soluble solid content, fruit soluble sugar content, ratio of sugar to acid and fruit Vc content of the ‘Dongzao’ fruits after girdling were significantly higher than those of the ‘Dongzao’ without girdling. The fruit soluble protein content of ‘Dongzao’ fruits without girdling was significantly higher than that of ‘Dongzao’ after girdling. ‘Dongzao’ girdling had no significant effect on fruit shape index and fruit titratable acid content. The result of comprehensive analysis is: the fruit quality of ‘Dongzao’ after girdling is significantly better than that ‘Dongzao’ without girdling.

Key words: ‘Dongzao’, girdling, fruit quality
