The aroeira (Myracroduon urundeuva Fr All) is a Anacardiaceae of natural occurrence since the Caatinga ties Argentina and Paraguay, being found in vegetal formations of caatinga, closed and forests pluvial. The species and to cultivate if hold of different form to the salinity, that is, each species of plant or to cultivate tolerates until certain salinity (Salinity threshold - SL), without reducing its potential income. This work had the objective to evaluate the germination if seeds of aroeira in different levels of salinity. One used different Chloride concentrations of sodium and calcium Chloride in the following amounts: 6,4g. 12,8g, 19,2g. The salinity intervened with all the parameters evaluated in the test of germination of the aroeira, to the measure that increased - the concentration of you leave yourself, had decrease in the analyzed 0 variable, being that, from 19,2g the germination of this culture sufficiently is harmed.
