Treatment duration of 12 pepper species by 3, 5, 7 days examined result, optimum processor of 12 pepper cultivars and carrier : water proportion was difference in species. However, radicle protrusion during priming(RPDP) does not happened and heightens germination rate, and Wang and Manitta species were 1:3(ratio), 7 day by treated that can shorten $T_{50}$, and all of the 10 cultivars were regard to processing of 1:7(ratio), 3 days was make satisfactory progress. Also cultivars of Jongggip was investigated by cultivars which germination rate and $T_{50}$ according to treatment duration and water proportion was irregular tendency than other cultivars. It was suggested that $20^{\circ}C$ was stable to radical protrusion and improved germination, while from $15^{\circ}C$ to $35^{\circ}C$ examined.

The purpose of this study was to find out the optimum SMP carriers in seeds of 12 pepper cultivars to alternate Micro-eel E. It showed that calcium carbonate caused the lower germination rates in proportion of water volumes and the radicle protrusion during priming period. Micro-cel E induced also the radical protrusion, even though it shortened $T_{50}$ in Wang cultivar, in proportion of water volumes. Diatomaceous earth shortened both $T_{50}$ and Mean days germination(MDG) in Choyang and Hyangchon cultivars, although it caused the radicle protrusion in treatment of $1.5{\times}$ water proportion. In Wang cultivar, Diatomaceous earth shortened $T_{50}$ by 0.60 and 0.05 days at 1.0 and $1.5{\times}$ water proportions respectively compared to the Micro-cel E at 5.0 and $7.0{\times}$ water proportions. Therefore, it could be suggested that Diatomaceous earth for the carrier might be suitable in pepper cultivars to alternate Micro-cel E, and $1.0{\times}$ water proportion should be available for processing.
