摘要 苹果树体高大,给果实采样、分析带来不便。为了便于比较及准确分析果实品质,在陕西渭北高原以乔化、南北行向的"红富士"苹果树为对象,采集树冠不同部位的果实,测定、分析果实品质,以确立分析果实品质时的合理采样部位。结果表明:苹果树冠不同部位的果形指数、着色指数、光洁指数、果皮花青苷含量、硬度、可溶性固形物、可溶性糖、维生素C含量均为树冠上部的较高,下部的较低,外围的较高,内膛的较低;单果质量、果锈指数、果皮叶绿素含量、可滴定酸含量为树冠上部的较低,下部的较高,外围的较低,内膛的较高;相同高度的树冠外围东、南、西、北侧的果实品质之间无显著差异。树冠外围中部、下部的果实品质平均值接近于树冠不同部位品质的平均值。树冠外围中下部可作为分析苹果品质的采样部位。 As apple tree had a big and tall crown,it was difficult for fruit sampling and analysis.In order to facilitate comparison and accurate analysis fruit quality,‘Red Fuji’ apple tree that grafted on vigorous rootstock,planted in north-south row,in full productive stage were selected as a sampling tree in Weibei Plateau,Shaanxi Province.The fruit that grown in different crown parts had been collected,and its quality had been measured and analyzed,so as to determine a reasonable parts in the crown for sampling and fruit quality analysis.The results showed that the fruit shape index,color index,clearness index,peel anthocyanin contents,firmness,soluble solids contents,soluble sugar contents,vitamin C contents of the fruit that grown in upper crown were higher than that grown in lower crown,grown in outer crown were higher than that grown in inner crown.The average fruit weight,fruit rust index,peel chlorophyll contents,titratable acid contents that grown in upper crown were lower than that grown in lower crown,and in outer crown were lower than that grown in inner crown.Fruit quality that grown in east,south,west,and north in outer crown,in same height,had no significant difference.The average of fruit quality that grown in middle-outer crown and lower-outer crown were close to the average of fruit quality that grown in different parts of the crown.The part between middle-outer crown and lowe-outer crown could be used as a reasonable part for sampling and fruit quality analysis.
