Ying-Ning Zou, Chun-Yan Liu, Qiang-Sheng Wu

The study was to research the effects of exogenous salicylic acid (SA; 10, 20, and 40 mg/L) on flower dropping and fruit setting of Citrus unshiu and NO3-N, soluble sugar, soluble protein, soluble starch, and non-structural carbohydrate concentrations in leaves and ovary. The present results showed that all the SA applications significantly decreased the flower dropping percentage but significantly increased the fruit setting percentage, which were related to improvement of nutrition and carbohydrates in the ovary caused by exogenous SA. Meanwhile, 20 mg/L SA displayed the best regulated effects.
