The objective of this study was to evaluate the germination of sunflower seeds under different concentrations of sodium chloride at 0, 25, 50, 100, 200 and 250 Mol.m-3. The experiment was carried out with four replications of 25 seeds per treatment. The parameters evaluated were: percentage, index of speed germination, average time and average speed of germination. Treatment with highest germination was 25 Mol.m-3 (81%), and from 50 Mol.m-3 (72%) there was decreased to 250 Mol.m-3 (22%), the index of speed germination showed similar behavior. To mean time the longest germination was observed for 250 mol.m-3 (5 days) and low for the control (3 days), the higher the presence of saline in the substrate causes lower germination speed. After analyzing the results the concentration of 25 Mol.m-3 presented better results for the variables analyzed and from 50 Mol.m-3 influences the salinity influenced negatively the germination promoting a decrease in the vigor.Downloads
