Abstract:
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.
