Abstract: The purpose of this project was to study the correlation of fruit nutrients (mineral element, total sugar, total acid and Vc) of ‘Huizao’ and ‘Junzao’ in Kashi, Xinjiang. The ripening fruits of 5 years old ‘Huizao’ and ‘Junzao’ were used as materials to determine the content of mineral elements, total sugar, total acid and Vc. The results showed that the order of the main mineral elements was K>N>Ca>P>Mg>Fe>Zn>Cu>Mn>B in both ‘Huizao’ and ‘Junzao’ fruits. 7 (Fe, Mg, K, P, N, Vc and total acid) of 13 indicators in ‘Junzao’ were significantly higher than that in ‘Huizao’. The contents of Ca and total sugar in ‘Junzao’ were also higher than that in ‘Huizao’ but did not reach the significant levels. However, the contents of B, Zn, Cu and Mn in ‘Huizao’ were higher than that in ‘Junzao’, but did not reach the significant levels. All 72 pairs of data from 13 indicators in ‘Huizao’ were correlated. Among them, 35 pairs were correlated significantly. In ‘Junzao’, 71 out of 72 pairs data were correlated, among them 30 pairs were correlated significantly. Collaboration and suppression coexisted among mineral elements, total sugar, total acid and Vc in the fruits of both ‘Huizao’ and ‘Junzao’. Fruit quality was the result of coordinated regulation of various nutrients.
