2004年，进行了一项试验以确定果实大小与其他果实品质参数之间的关系，以评估苹果果实大小是否与果实品质差相关。该试验在特伦蒂诺-上阿迪杰地区瓦尔苏加纳山谷中部斯库雷勒镇附近的两个商业果园进行。 “金冠”（克隆 B）和“红酋长”（Malus x Domestica Borkh.）树在重且标准的作物负荷下种植。每个品种的一半树木经过手工间伐，以获得每平方厘米约 8 个果实 TCSA 的重作物负荷，而另一半则被间伐以获得每平方厘米约 6 个果实 TCSA 的标准作物负荷。收获时，对果实进行计数，并记录果实直径、果实重量、果肉硬度、总可溶性固形物（TSS）含量和可滴定酸度。还进行了相关和回归分析，以确定水果质量参数之间的关系。在栽培品种中，重茬树的果实大小和果实重量低于标准种植树。另一方面，重茬树木的 TSS 含量和果肉硬度更高。对于两个品种和两种作物负荷水平，果实大小和 TSS 含量之间存在轻微的负相关，而果实重量和果肉硬度之间存在更大的负相关。发现的唯一强正相关是果实大小和果实重量之间。除尺寸和重量外，本试验中评估的所有参数彼此相关性都很弱。重茬树的果实较小、较硬、TSS含量较高，这表明适度增加作物负荷不会影响果实品质。
In 2004, a trial was carried out to determine the relationships between fruit size and other fruit quality parameters in order to assess whether small size is correlated with poor fruit quality in apples. The trial was carried out in two commercial orchards near the town of Scurelle in the middle of Valsugana valley in Trentino Alto Adige region. 'Golden Delicious' (Clone B) and 'Red Chief (Malus x domestica Borkh.) trees were cultivated under heavy and standard crop loads. Half of the trees of each cultivar were hand thinned to obtain a heavy crop load of about eight fruits per square centimeter TCSA, and the other half were thinned to obtain a standard crop load of about six fruits per square centimeter TCSA. At harvest, fruits were counted, and fruit diameter, fruit weight, flesh firmness, total soluble solids (TSS) content and titratable acidity were recorded. Correlation and regression analysis were also performed in order to determine the relationships among fruit quality parameters. In cultivars, fruit size and fruit weight were lower with heavy cropping trees than with standard cropping trees. On the other hand, TSS content and flesh firmness were higher with heavy cropping trees. With both cultivars and at both crop load levels, there was a slightly negative correlation between fruit size and TSS content, and a more negative correlation between fruit weight and flesh firmness. The only strong positive correlation found was between fruit size and fruit weight. All of the parameters evaluated in this trial were weakly correlated with each other, except for size and weight. Fruits from heavy cropping trees were smaller, firmer, and had a higher TSS content, which indicates that a moderate increase in crop load does not affect fruit quality.
