A Study of Scion Phenotypes in Pummelo Grafted onto a New Citrus Rootstock Citrus junos ‘Pujiang Xiangcheng’

Citrus is one of the most important fruit crops in world. junos Siebold ex Tanaka cv. Pujiang Xiangcheng a new rootstock with good grafting affinity and multiple abiotic stress tolerance. In this study, effects ‘Pujiang Xiangcheng’ two commonly used rootstocks for maxima (Burm.) Merrill Guanxi Miyou, considering their growth, photosynthetic performance, phytohormones quality, were evaluated. There was little difference between three graft combinations height diameter scions. However, can cause an up-regulated capacity. addition, ‘Guanxi Miyou’ on had highest total sugar (TS) content (129.28 mg·g?1) lowest titratable acid (TA) (0.78 g·100 mL?1) 2020 TSS (11.84%) 2021. no significant TSS-to-acid ratio trifoliate orange (13.41) (15.68), but it significantly higher than that sour pummelo (11.61). Moreover, comprehensive quality better based two-year statistics. We suggest might be appropriate production compared orange.
