Resumo: 	The use of antitranspirants in the nursery may induce greater seedling resistance to water stress after planting. This essay evaluated the effect of antitranspirante doses on stomatal conductance in seedlings of Cordia trichotoma subjected to water stress. Seedlings received the control treatment which consisted of water pulverization and doses of 1.5% and 3.0% of antitranspirant diluted in water. The essay was conducted in randomized blocks with ten repetitions of two saplings each. Measurements included stomatal conductance until the 12 day after induced water stress and leaf water content (LWC). Seedlings that received antitranspirant presented the lesser stomatal conductance, which is in accordance with the application of antitranspirants because of film formed on the leaf surface which induces stomata closure. There was no statistical difference in LWC due to the treatments. The stomatal conductance behavior showed a quadratic form through time being well correlated with air temperature and moisture. The use of 1.5% of antitranspirant in seedlings of C. trichotoma resulted in lower water loss through reduction in stomatal conductance than control seedlings.
