Cyclocarya paliurus has traditionally been used as medicine or nutraceutical foods in China, which has great value for market prospects. In order to determine the effects of nitrogen and phosphorus coupling on photosynthesis, chlorophyll (Chl) fluorescence and chlorophyll level of C. paliurus, a hydroponic experiment was laid out in a completely randomized block design with two-way factorial was used for C. paliurus cultivars with three N and three P treatments replicated three timesnin a greenhouse. The factorial combination of three N concentrations (50(low), 150(medium) and 250(high) mg/L) and three P concentrations (5(low), 15(medium), and 25(high) mg/L), totally nine treatments. Photosynthetic parameters (Pn, Ci, Gs and Tr), ChlF parameters (F0, Fm, Fv/Fm, Fv, PSⅡ, ETR, NPQ and qP) and chlorophyll level (SPAD) of leaves were measured at 30 and 60 days. The results demonstrated that the coupling of nitrogen and phosphorus had an interaction on photosynthesis, chlorophyll fluorescence and relative chlorophyll content of C. paliurus leaves. The photosynthetic rate, intercellular carbon dioxide concentration and stomatal conductance were the highest in N2P3 treatment (30 or 60 day), and the lowest were in N1P1 treatment. On the 60th day, F0, Fm, Fv were the lowest in N2P1 treatment, ФPSII and qp were higher in N2P3 treatment, NPQ was the highest in N3P1 treatment, Fv/Fm and ETR reached the maximum in N2P2 and N3P1 treatment respectively. The relative chlorophyll content reached the maximum in N2P2 treatment. Additionally, the correlation analysis results showed that the Pn was significantly positively correlated with Fv/Fm PhiPS2 Ci, Gs, Tr and SPAD value, and was significantly negatively correlated with F0 and NPQ, Fv, PhiPS2, qp was positively correlated with SPAD value. Thus, photosynthetic parameters, ChlF parameters and chlorophyll level measurements provide valuable physiological data. N2P2 or N2P3 treatment was more beneficial to the growth of C. paliurus.
