Abstract: This study aimed to evaluate the effects of foliar application of salicylic acid on gas exchange of Japanese Hiroshi cucumber grown under saline nutrient solutions in a NFT hydroponic system. The experiment was developed under greenhouse conditions in Pombal - PB in a NFT hydroponic system - Laminar Nutrient Flow Technique. The experimental design was completely randomized, in a split-plot scheme, whose treatments consisted of four saline levels of the nutrient solution - CEsn (2.1, 3.6, 5.1, and 6.6 dS m-1) and two concentrations of salicylic acid (0 and 5.4 mM) with three replicates and two plants per plot. The saline nutrient solution from 2.1 dS m-1 decreased stomatal conductance, CO2 assimilation rate, and transpiration, and increased the internal CO2 concentration of Japanese cucumber plants, at 40 days after transplanting.
