  The study had the aim to evaluate the germination responses provoked by water restriction and by the effect of temperature on seeds of S. bicolor cultivar BR-700. The experimental design was to carried out in 38 factorial scheme, with 3 temperature levels (26, 30 and 34C), combined with 8 osmotic potential levels that simulate water restriction ( s = 0.0, -0.1, -0.2, -0.3, -0.4, -0.5, -0.6 and -0.7 MPa). The analyzed variables were the germination percentage (%G) and the mean germination time (MGT). It was showed progressive fall in %G due to the decreased s of the environment, independent of the temperature, caused by the low water conductivity and slow water absorption by the seed. MGT reduced occasioned by temperature increased, in the interval between 26-34C, provoked by an acceleration of biochemical reactions involved in germination. Moreover, the water restriction, as well as the s reduced, proportioned a maximization of MGT.
