Abstract With water culture, this paper studied the effects of exogenous spermidine (Spd) on the net photosynthetic rate (P_n), intercellular CO₂ concentrations (C_i), stomatal conductance (G_s), transpiration rate (T_r), apparent quantum yield (?_c), and carboxylation efficiency (CE) of cucumber seedlings under hypoxia stress. The results showed that P_n decreased gradually under the hypoxia stress, and reached the minimum 10 days later, which was 63.33% of the control. Compared with that of the hypoxia-stressed plants, the P_n 10 days after the application of exogenous Spd increased by 1.25 times. A negative correlation (R² = 0.473–0.7118) was found between P_n and C_i, and G_s and T_r changed in wider ranges, which decreased under the hypoxia-stress, but increased under the hypoxia-stress plus exogenous Spd application. There was a significant positive correlation between G_s and T_r (R² = 0.7821–0.9458), but these two parameters had no significant correlation with P_n. The hypoxia stress induced a decrease of ?_c and CE by 63.01% and 72.33%, respectively, while the hypoxia stress plus exogenous Spd application made ?_c and CE increase by 23% and 14%, respectively. The photo-inhibition of cucumber seedlings under hypoxia stress was mainly caused by non-stomatal inhibition, while the exogenous Spd alleviating the hypoxia stress by repairing photosynthesis systems.
