The characteristics of rootstock have impacts scion’s nutritional status, resistance to environmental stresses and adaptation to a specific region. Thus the performance of a cultivar is largely dependent on the rootstock-scion interactions. In this study, seasonal variations in mineral nutrients of ‘Nova’ and ‘Robinson’ mandarin cultivars budded on different citrus rootstocks were investigated under Dörtyol-Hatay (Turkey) ecological conditions. Nitrogen (N), phosphorus (P) and potassium (K) contents of the leaves exhibited slightly similar trends with each other. In general, these nutrients decreased from January to March-April and increased in the subsequent growing season until mid- and late summer, then decreased again until December. Similar trends were also observed in calcium (Ca) and magnesium (Mg) concentrations of leaves. Leaf Ca and Mg concentrations decreased from January to March, then increased during fruit development until July-August and decreased again during autumn and winter. Also, micro elements such as iron (Fe), zinc (Zn), manganese (Mn) and copper (Cu) increased from January to May–June and then gradually decreases began during the growing season until December. Throughout the entire growing season, mean macro nutrients such as N, K and Ca concentrations ranged from 1.89% (‘Nova’/Carrizo citrange) to 2.02% (‘Robinson’/Carrizo citrange), from 1.10% (‘Robinson’/Carrizo citrange) to 1.39% (‘Nova’/Carrizo citrange) and from 2.62% (‘Nova’ /sour orange) to 3.48% (‘Robinson’/Troyer citrange), respectively. Phosphorus and Mg concentrations showed slightly similar trends and varied between 0.14–0.16% and between 0.31–0.39%, respectively. The ranges of mean micro nutrients such as Fe, Zn, Mn and Cu concentrations were between 65.3 and 75.4 mg kg⁻¹, 33.7 and 39.6 mg kg⁻¹, 64.1 and 70.6 mg kg⁻¹, and 10.5 and 11.4 mg kg⁻¹, respectively. It can be concluded that rootstock-scion relations can cause considerable differences in seasonal nutrition of mandarin cultivars.

砧木的特性会影响接穗的营养状况，对环境压力的抵抗力以及对特定区域的适应性。因此，一个品种的表现很大程度上取决于砧木-接穗的相互作用。在这项研究中，研究了在Dörtyol-Hatay（土耳其）生态条件下，萌芽于不同柑橘类砧木上的'Nova'和'Robinson'普通话品种的矿质养分的季节性变化。叶片的氮（N），磷（P）和钾（K）含量彼此之间显示出相似的趋势。通常，这些养分从1月至3月至4月减少，并在随后的生长季节增加至夏至中期和夏末，然后再次减少直至12月。在叶片的钙（Ca）和镁（Mg）浓度中也观察到类似趋势。从一月到三月，叶片中的钙和镁含量下降，然后在果实发育期间一直上升，直到七月至八月，在秋季和冬季再次下降。另外，铁（Fe），锌（Zn），锰（Mn）和铜（Cu）等微量元素从1月至5月至6月增加，然后在生长季节至12月开始逐渐减少。在整个生长季节中，诸如N，K和Ca的平均大量营养素含量从1.89％（“ Nova” /柑桔橙）到2.02％（“ Robinson” /柑桔橙）从1.10％（“ Robinson” /柑桔）不等。柠檬橙）至1.39％（'Nova'/ Carrizo柠檬橙）和2.62％（'Nova'/酸橙）至3.48％（'Robinson'/ Troyer柠檬橙）。磷和镁的浓度显示出略微相似的趋势，并且分别在0.14-0.16％和0.31-0.39％之间变化。^-1，33.7和39.6毫克千克^-1，64.1和70.6毫克千克^-1，和10.5和11.4毫克千克^-1，分别。可以得出结论，砧木与接穗之间的关系可能会引起普通话品种季节性营养的显着差异。
