The object of this study was to investigate the growth, photosynthesis and carbohydrate of 'Shatangju' mandarin grafted on various rootstocks. The tree vigor, net photosynthesis (Pn), transpiration rate (Tr), stomatal conductance (Gs), intercellular CO2 concentration (Ci), leaf chlorophyll, carbohydrates of 'Shatangju' mandarin budded on Ichang papeda (Citrus ichangensis Swingle), Trifoliate orange [P. trifoliate (L.) Raf.], 'Shatangju' mandarin (C. reticulata Blanco cv. Shatangju), Fragrant orange (C. junos Sieb.ex Tanaka), Rough lemon (C. jambhiri Lush) were evaluated. The scion height, trunk cross-section area (TCSA), leaf area and shoot length of 'Shatangju' on Fragrant orange and Rough lemon were significantly bigger than that on the Ichang papeda. The lowest affinity was found with Ichang papeda, which showed the highest rootstock/scion ratio (2.08). Total leaf chlorophyll content range from 0.85 mg/g FW to 1.40 mg/g FW, significantly higher leaf chlorophyll content was found in trees grafted on Rough lemon and Trifoliate orange than other grafting combinations. Trees on Fragrant orange had the highest net photosynthesis (Pn), transpiration rate (Tr), stomatal conductance (Gs), while Ichang papeda induced the lowest photosynthesis rates. As the production of CO2 photosynthesis, high photosynthesis efficiency led to higher carbohydrate (total soluble sugar, sucrose, reduced sugar content) in 'Shangtangju' leaves budded onto Fragrant orange and Rough lemon rootstocks compared to trees on the Ichang papeda. The data confirmed that the low affinity of Ichang papeda rootstock and 'Shatangju' mandarin scion combination caused the lower photosynthesis efficiency and tree vegetative growth. The Fragrant orange rootstock could be a suitable candidate for the 'Shangtangju' mandarin production in citriculture.
