Selection of rootstock is very important for citrus production. Besides its major role on resistance, the rootstock also can affect fruit production and quality. Currently, the main concerns on selection of rootstock for citrus production are compatibility and resistance, due to less information on the impacts of rootstock to the performance of scion varieties. This study aims to provide information on performances of navel orange varieties on different rootstocks. Three late-ripening navel orange varieties (Citrus sinensis var. Powell, Chislett and Banfield) grafted on seven rootstocks (Swingle citrumelo (C. paradisi×P. trifoliata), Carrizo citrange (C. sinensis×P. trifoliata), X639 (C. reticulata×P. trifoliata), MXT (C. sinensis×P. trifoliata), Hongju (C. reticulata), Ziyang Xiangcheng (C. junos) and trifoliate orange (P. trifoliata)) were used as plant materials for comprehensive comparison of the performances on tree growth, fruit yield and quality in 21 scion–stock combinations. Investigation was carried out in these combinations in field nine years after planting. Vigorous growth of all the three late-ripening navel orange varieties was observed on Carrizo citrange with the largest canopy volume at 33.34 m³ and the highest yield at 29.43 kg per tree, but a low yield efficiency at 2.87 kg m⁻³. On the contrary, those on trifoliate orange had the smallest canopy volume at 10.79 m³ and the lowest fruit yield at 12.51 kg per tree, but the highest yield efficiency at 3.95 kg m⁻³. Rootstocks did not show significant effects on fruit size, fruit shape index, peel thickness and the edible rate of the fruits, but fruit quality was significantly affected by the rootstocks. Fruits from the trees grafted on trifoliate orange presented the best quality with significantly higher total soluble solids (TSS) content than those on Ziyang Xiangcheng and Hongju, and also the highest ratio of TSS/titratable acidity (TA). The TA content was observed from the fruits on X639 at 0.59 g 100 mL⁻¹. Vitamin C (Vc) content of fruits on Hongju was the highest at 49.25 mg 100 mL⁻¹. Growth vigor of the trees was positively correlated with fruit yield at an extremely significant level. The canopy volume was negatively correlated with yield efficiency, but positively correlated with compatibility index. Results of this study indicated that the rootstock has great impacts on the growth vigor of the tree, yield efficiency and quality of the fruit. In order to achieve good quality and yield efficiency for navel orange production, less growth vigor rootstock such as trifoliate orange is highly recommended.

砧木的选择对于柑橘的生产非常重要。砧木除了对抗性起主要作用外，还可以影响果实的产量和品质。当前，由于关于砧木对接穗品种性能的影响的信息较少，因此对于柑橘类生产选择砧木的主要问题是相容性和抗性。这项研究旨在提供有关脐橙品种在不同砧木上表现的信息。三晚熟脐橙品种（脐橙嫁接七个砧木（欢乐之citrumelo（品种鲍威尔，Chislett和班菲尔德）C.葡萄柚×P。生苗），卡里佐枳橙（华支睾吸虫×P。生苗），X639（Ç网纹×P. trifoliata），MXT（中华× 用三叶草，红菊（C. reticulata），紫阳香城（C. junos）和三叶橙（P. trifoliata）作为植物材料，对21种接穗砧木的生长，果实产量和品质进行综合比较。组合。种植九年后，在田间对这些组合进行了调查。在Carrizo citrange上观察到所有三个晚熟脐橙品种的旺盛生长，最大冠层体积为33.34 m ³，最高产量为每棵树29.43 kg，但在2.87 kg m ^-3时产量效率较低。相反，在三叶橙色上的那些冠层体积最小，为10.79 m ³每棵树的最低水果产量为12.51 kg，但最高产量效率为3.95 kg m ^-3。砧木对果实的大小，果实形状指数，果皮厚度和可食性没有显着影响，但砧木显着影响果实质量。用三叶酸橙嫁接的树上的果实质量最好，总可溶性固形物（TSS）含量显着高于资阳香城和红菊，并且TSS /可滴定酸度（TA）最高。在X639上以0.59 g 100 mL ^-1从果实上观察到TA含量。红菊果实中的维生素C（Vc）含量最高，为49.25 mg 100 mL ^-1。树木的生长活力与果实产量呈极显着正相关。冠层体积与产量效率呈负相关，但与相容性指数呈正相关。研究结果表明，砧木对树的生长活力，产量效率和果实品质有很大影响。为了获得生产脐橙的良好质量和增产效率，强烈建议使用生长力较低的砧木，例如三叶形橙。
