Various hydration treatments have been devised to improve the rate and univormity of seed germination as well as seed viability. Hydropriming and priming, the imbibitaion of seeds in distilled water and osmotic solutions, respectively, are useful techniques for early establishment of uniform seedlings. In this study, the optimum conditions were determined for hysropriming of cucumber seeds. Effects of hydropriming were also compared to those of osmotic priming. Seeds, hydroprimed with distilled water and primed with 50 mM $NaNO_3$at 20 for 24 hour, showd shorter number of days required to reach 50% of the final germination percentage ($T_{50}$), and mean number of days to germinate (MDG) that those untreated seeds. Hydroprimed with 10 mL distilled water showed better results in improving the rate of germination thatn other treatments tested. Hydropriming of the aged seeds improved germination percentage at 15$^{circ}C$ and 25$^{circ}C$. The $T_{50}$ and MDG values were reduced significantly by hydropriming of the aged seeds regardless of germination temperature. In addition to being simple and inexpensive, the hydropriming resulted in early germination at low temperature. he hydropriming was also effective in increase of germination percentage and normal seedlings.
