Correlation Analysis of Mineral Elements and Soluble Sugar in Different Maturity Stages of Fuji Apple

【Objective】 To study the relationship between the mineral content and the soluble sugar content in the fruits of Changfu 2 and Yanfu 6 in hongqipo farm of Aksu Area in different maturity stages, so as to provide a theoretical basis for the high quality and high yield cultivation of apples.【Methods】 Taking Changfu 2 and Yanfu 6 as test materials, the relationship between mineral elements and soluble sugar components in fruit was investigated.The types and contents of soluble sugar were determined by high performance liquid chromatography, and minerals in fruit were determined by Kjeldahl nitrogen method, vanadium molybdenum yellow colorimetry, flame photometer, atomic absorption spectrophotometry and curcumin colorimetry Material elements were determined.【Results】 On September 16, the contents of sucrose, glucose and sorbitol of Changfu 2 and Yanfu 6 were 20.12 and 36.4 mg/g, 33.82 and 18.29 mg/g, 3.52 and 4.68 mg/g, respectively.During the period from October 5 to October 25, the fructose contents of the two varieties were 71.50 and 90.43 mg/g, 91.64 and 78.69 mg/g, 94.48 and 82.52 mg/g, respectively.The contents of N, Ca, Cu, Fe and Zn in the fruit of Changfu 2 have been in a downward trend from September 16 to October 25.The contents of N had a significant positive correlation with the contents of Ca, Cu and Fe, the contents of sucrose had a significant negative correlation with Ca, Cu and Fe, and the contents of Zn had a significant negative correlation.In Yanfu 6, the contents of Ca and sorbitol had a significant negative correlation, Mg and Fe had a significant positive correlation with the contents of sucrose, and there was a significant negative correlation between B elements and fructose.【Conclusion】 On October 15, the glucose and sorbitol content of Changfu 2reached the maximum, and the glucose content ofYanfu 6was also the highest at this time.On October 25, the sucrose content of the two varieties reached the highest value.At this time, the fructose content of Changfu 2 also reached the maximum, and that ofYanfu 6reached the maximum on October 5.In Changfu, the contents of total phosphorus and B reached the maximum on October 5, the contents of total potassium increased from October 15 to October 25, and the content of Mg was in a downward trend during this period.From September 16 to October 25, the contents of total nitrogen, Fe, Ca, Cu and Zn were in a downward trend.In Yanfu 6, the total nitrogen content increased in a ‘S’ pattern from September 16 to October 25, and the contents of Ca, Cu and Zn decreased during this period.The contents of total phosphorus, iron and magnesium increased continuously from October 15 to 25, while the content of total potassium decreased.
