To the better management of spring frost problem in the apricot cultivars, evaluation of biochemical changes in flower and/or flower organs during bud break could be one of the key factors. In this study, the relationship between the biochemical metabolites such as amino acids and minerals in the receptacle and pistil organs of two different apricot cultivars (frost-sensitive and frost-tolerant) and their relative effects on the frost tolerance of the cultivars and their organs were investigated during full blooming stage. In both apricot cultivars, it was found that the cell death points (CDP) of flower receptacle (− 6.3 to − 8.4 °C) were at higher temperatures than the CDP of flower pistil organs (− 13.1 to − 14.5 °C). Receptacle organs in flower, therefore, had less tolerance to spring frost damage. In addition, significant differences in mineral and amino acid contents were detected both between apricot cultivars and between the receptacle and pistil organs of the cultivars. Amino acid and mineral contents were lower both in the freezing-sensitive apricot cultivar (“Mihralibey”) and the freezing-sensitive organ (receptacle) in comparison with the freezing-tolerant apricot cultivar (“Iğdır Şalak”) and the freezing-tolerant organ (pistil). A significant negative correlation was also observed between the mean CDP values and both amino acid and mineral contents in the receptacle and pistil organs of both apricot cultivars. A negative correlation was found between CDP values and glutamate from amino acids and N, K, and Mg from minerals, and also these were determined that they had positive effects on frost tolerance increase. An important finding from our work revealed that the amount of each mineral and amino acid allocated differently to the receptacle and pistil organs of the apricot cultivars. The understanding of the amino acids and the mineral dynamics may contribute to improving the tolerance of flowers of apricot or other deciduous species to frost damage during spring. In the future, we may conclude that protection strategies such as increasing amino acids and mineral content in the receptacle organ of flowers would be necessary to cope with the negative effects of spring frost.

为了更好地管理杏品种的春季霜冻问题，评估花蕾和/或花器官在萌芽期间的生化变化可能是关键因素之一。本研究探讨了两个不同的杏品种（霜敏感型和耐霜型）的花托和雌蕊器官中氨基酸和矿物质等生化代谢物之间的关系及其对品种及其器官抗霜性的相对影响。在盛花期进行调查。在两个杏品种中，发现花托的细胞死亡点 (CDP)（- 6.3 至 - 8.4 °C）的温度高于花雌蕊器官的 CDP（- 13.1 至 - 14.5 °C）。因此，花中的花器器官对春季霜冻的耐受性较差。此外，在杏品种之间以及品种的花托器官和雌蕊器官之间检测到矿物质和氨基酸含量的显着差异。与耐冻杏品种（“Iğdır Şalak”）和耐冻杏品种相比，冷冻敏感杏品种（“Mihralibey”）和冷冻敏感器官（容器）的氨基酸和矿物质含量均较低（雌蕊）。在两个杏品种的花托和雌蕊器官中，平均 CDP 值与氨基酸和矿物质含量之间也观察到显着的负相关。氨基酸中的CDP值与谷氨酸盐和矿物质中的N、K、Mg呈负相关，并确定它们对提高抗冻性有积极影响。我们工作的一项重要发现表明，每种矿物质和氨基酸的数量不同地分配到杏品种的花托和雌蕊器官。对氨基酸和矿物质动力学的了解可能有助于提高杏或其他落叶植物的花朵对春季霜冻损害的耐受性。未来，我们可能会得出结论，增加花托器官中氨基酸和矿物质含量等保护策略对于应对春季霜冻的负面影响是必要的。对氨基酸和矿物质动力学的了解可能有助于提高杏或其他落叶植物的花朵对春季霜冻损害的耐受性。未来，我们可能会得出结论，增加花托器官中氨基酸和矿物质含量等保护策略对于应对春季霜冻的负面影响是必要的。对氨基酸和矿物质动力学的了解可能有助于提高杏或其他落叶植物的花朵对春季霜冻损害的耐受性。未来，我们可能会得出结论，增加花托器官中氨基酸和矿物质含量等保护策略对于应对春季霜冻的负面影响是必要的。
