摘要

摘要目前的研究追踪了两种本地桃子品种(“Laskava”和“Evmolpiya”)从果实形成到完全成熟在五个日历周内的发展变化。为了寻找一种无损的成熟度评价方法,对硬度、颜色、大小、重量、干重、灰分含量和TSS值等参数进行了评价。结果发现,在成熟期,果实大小增加30%,重量增加1.8-2倍。TSS数据变化不大,说明桃的主要营养物质是在发育初期积累的。颜色指标的变化趋势如下:“L”、“h”、“b”值呈下降趋势,“c”值呈上升趋势。在评估期间,石头的大小不会发生剧烈变化。水分含量也没有显著变化,尽管在果实生长的初始阶段,它不能以多汁为特征。硬度逐渐降低。所获得的结果为建立一个预期标记的数据库提供了依据,该数据库可以在果实不被从树上拔出或损坏的情况下指示成熟的开始。

Dynamic biometric data, total soluble solids, ash content, firmness, and color characteristics of two peach varieties
Abstract. The present study tracks changes in the development of two native peach varieties (“Laskava” and “Evmolpiya”) from fruit formation to full ripening within five calendar weeks. In search for a non-destructive method for maturity assessment, the parameters firmness, color, size, weight, dry weight, ash content, and TSS values were evaluated. It was found that a 30% increase in size and a 1.8-2 times increase in weight occurred during the ripening period. The TSS data did not change radically, which shows that the main nutrients of the peach accumulate in the early stages of development. The color indicators change in the following trend: a decrease in the “L”, “h” and “b” values, and a tendency of increase in the “c” values. The stone size does not change drastically during the evaluation time. The moisture content also does not change significantly, although in the initial stage of fruit growth it cannot be characterized by juiciness. Firmness progressively decreases. The obtained results show grounds for the creation of a database of expected markers which may indicate the onset of maturity without the fruit being pulled from the tree or damaged.
