摘　　要：2008—2009年,测定北京市昌平区34个成龄富士苹果园果实矿质营养含量与单果质量等几个主要品质指标,应用典型相关和回归分析方法,探讨果实矿质营养含量与几个主要品质指标的关系。结果表明,果实单果质量主要受果实中全磷、钾、钙、铁和硼含量的影响,并且磷>钾>硼>铁>钙,钾、钙含量与果实单果质量呈正相关,磷、铁、硼含量与之呈负相关;果实硬度与氮、钾含量呈负相关,而与钙、铁含量呈正相关;果实可溶性固形物含量主要受果实中全氮、磷、钾、钙和铁含量的影响,并且氮>磷>钾>铁>钙,果实中氮、磷含量与果实可溶性固形物呈负相关,而钾、铁含量呈正相关;提高果实全磷、钾、锌的含量可以降低果实酸度。The fruit quality and mineral nutrition contents of fruit were surveyed at 34 adult＇Fuji＇ apple orchards in Changping District of Beijing during 2008 to 2009.The methods of canonical correlation analysis and regression analysis were applied to find out relationship of fruit mineral nutrition with several key quality indicators.The results showed that mass per fruit was influenced by P,K,Ca,B,Fe content of fruit and PKBFeCa,fruit mass had positive correlation with K,Ca and negative correlation with P,B,Fe content of fruit.Firmness was negative correlation with N,K and positive correlation with Ca,Fe content of fruit.The soluble solids was influenced by N,P,K,Ca,Fe content of fruit and N PKFeCa,and soluble solids was negative correlation with N,P and positive correlation with K,Fe content of fruit.Titratable acid was reduced by increasing P,K and Zn content of fruit.
