Study on the Puang and Jed-Bai local cucumber varieties seed dormancy and breaking treatments were investigated by 3 seed lots. Those seed lots harvested from the non-incubated fruit compared with the 5 and 7 days incubated fruits. The various physical and chemical treatments were investigated for seed dormancy and improving germination. The after-ripening evidence should be noted seed dormancy of both varieties by 20 days discontinuous sun-dry treatment and 9 days hot-air dry (40 deg C) was also effectived. By the way, the aging treatment (45 deg C 100 percent RH for 2 days) and 9 days hot-air dry were induced high germination of Jed-Bai The 0.2 percent KNO3 and 1.5*10*[-6) M exogenous GA3 solution were stimulated Jeb-Bai seed germination better than Puang variety. The possible relationship between the various treatments kinetin and GA3+ethephon and improved germination are more discussion of the mechanism combination solution GA3+ethephon also the endogenous seed hormones determination.
