摘要
【目的】研究阿克苏地区红旗坡农场长富2号和烟富6号苹果不同成熟期的果实中,矿物质含量和可溶性糖含量变化的关系,为苹果优质丰产栽培提供理论基础。【方法】以长富2号和烟富6号为材料,研究不同成熟期果实内矿物质元素和可溶性糖组分之间的相互关系,采用高效液相色谱仪,测定可溶性糖种类和含量,利用凯氏定氮法、钒钼黄比色法、火焰光度计法、原子吸收分光光度、法姜黄素比色法测定果实中的矿物质元素。【结果】9月16日,长富2号和烟富6号的蔗糖、葡萄糖和山梨醇含量分别是20.12和36.4 mg/g,33.82和18.29 mg/g,3.52和4.68 mg/g,存在显著差异,在10月5~25日期间2品种的果糖含量分别是71.50和90.43 mg/g,91.64和78.69 mg/g,94.48和82.52 mg/g,均达到显著水平显著差异。长富2号果实中的N、Ca、Cu、Fe和Zn含量在9月16日~10月25日一直处于下降趋势,N含量与Ca、Cu、Fe含量呈显著正相关,蔗糖与Ca、Cu、Fe呈显著负相关,与Zn含量呈极显著负相关,在烟富6号中Ca元素与山梨醇呈显著负相关,Mg和Fe元素对蔗糖呈极显著正相关,B元素与果糖呈极显著负相关。【结论】10月15日,长富2号的葡萄糖和山梨醇含量达到最大值,烟富6号此时的葡萄糖含量也是最高的。10月25日,2品种的蔗糖含量达到最高值。长富2号的果糖含量也达到最大值,烟富6号在10月5日达到最大值。长富2号全磷和B含量在10月5日达到最大值,全钾含量在10月15~25日上升,Mg含量在此期间处于下降趋势,9月16日~10月25日,全氮、Fe、Ca、Cu和Zn含量一直处于下降趋势。烟富6号中全氮含量从9月16日~10月25日期间,呈‘S’型增长,Ca、Cu和Zn含量在此期间处于下降状态,10月15~25日期间全磷、Fe、Mg含量不断上升,全钾含量在此前间下降。
【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 6reache
