Tangor ( × ) cultivars obtained through interspecific hybridization have gained popularity in various countries, including South Korea. However, tangor has a relatively short history of cultivation and thus has been less well researched in terms of physiology and opping technology compared to mandarin. In addition, although tangor grows more vigorously than mandarin and thus has high nutrient demands and longer harvest time, it is more prone to various physiological disorders. Furthermore, the demand for nutrients could vary depending on the cultivars even within the same species. Thus, the current study examined the effects of nitrogen deficiency and resupply on the uptake of mineral nutrients using a specific cultivar 'Shiranuhi' as a case study. In this study, the tangor cultivar 'Shiranuhi' was cultivated in a hydroponics system, which allows the control of nutrient contents, and changes in mineral nutrient contents under nitrogen deficiency and nitrogen resupply were examined. Based on this, the results show the straightforward relationship between nitrogen and other mineral nutrients under a hydroponic system applying the cultivation of tangor. This implies that the hydroponics system can be applied to tangor cultivation and efficiently and widely expanded in Northeast Asia, and the income of growers will increase through the production of high-quality fruits.
通过种间杂交获得的坦普尔橙（×）品种在包括韩国在内的各个国家都受到了欢迎。然而，坦普尔橙的种植历史相对较短，因此与柑橘相比，其在生理学和采后技术方面的研究较少。此外，尽管坦普尔橙比柑橘生长更旺盛，因此对养分的需求较高且收获期较长，但它更容易出现各种生理失调问题。此外，即使在同一物种内，不同品种对养分的需求也可能有所不同。因此，本研究以特定品种“不知火”为例，研究了缺氮和再供应对矿质养分吸收的影响。在本研究中，坦普尔橙品种“不知火”在水培系统中种植，该系统可以控制养分含量，并研究了缺氮和氮再供应条件下矿质养分含量的变化。基于此，结果表明在应用坦普尔橙种植的水培系统中，氮与其他矿质养分之间存在直接关系。这意味着水培系统可应用于坦普尔橙种植，并在东北亚地区高效广泛推广，种植者通过生产优质水果将增加收入。
