A salt stress was induced using solution of NaCl and CaCl2 on the following potentials: zero (control);
-0,2; -0,4; -0,6; -0,8; -1,0; -1,2; -1,4 and -1,6. The seeds were previously scarifield with H2SO4 (10 min.) and
after incubated on saline solution at 30ºC. A decrease in the rate germination percentage was observed with the
increase of salt concentracion. The germination was strongly inhibited at -1,4MPa in NaCl and -1,0MPa in CaCl2.
The influence of the sowing depth in the emergence was observed after the scarification in H2SO4 compared to
intacts seeds, with or without pre embebition on GA3 (20ppm during four hours).The seeds were snow on the fiels
at two, five, 10cm depth. The scarified seeds pre-embebid on GA3 sowed in 2cm of depth showed the best
performance, with 55% of germination.
