英文摘要	Knowledge about the effect of chemical conditioners on the reduction of the deleterious effects caused by salinity on crops is of great importance for the expansion of the cultivation of vegetable crops such as zucchini in the semi-arid region of the Northeast. In this context, the objective of the present study was to evaluate the effect of the foliar application of hydrogen peroxide as a mitigator of salt stress on the gas exchange, production, and postharvest fruit quality of zucchini cultivated in a hydroponic system. The study was conducted in NFT-type (Nutrient Film Technique) hydroponic system in a greenhouse, in Pombal - PB, Brazil. The experimental design was completely randomized, in a 4 x 4 factorial scheme, corresponding to four levels of electrical conductivity of the nutrient solution - ECns (2.1 (control); 3.6; 5.1 and 6.6 dS m(-1)), and four concentrations of hydrogen peroxide - H2O2 (0; 20; 40 and 60 mu M), with three replicates. Nutrient solution with electrical conductivity above 2.1 dS m(-1) caused a reduction in gas exchange and the total number of fruits of zucchini. An increase in nutrient solution salinity levels increased the total soluble solids content of the fruits and the initial fluorescence of zucchini. Under conditions of nutrient solution salinity above 2.1 dS m(-1) , hydrogen peroxide could not mitigate the effects of salt stress. Application of 20 mu M of H2O2 when the plants were grown in a nutrient solution of 2.1 dS m(-1) promoted higher total fruit weight and basal diameter of the fruits.
