Abstract

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.

고추 12 품종의 SMP 처리시 carrier와 수분의 배율, 처리기간 및 처리온도에 대한 조사 결과 적정 처리기간과 carrier와 수분의 배율은 품종마다 차이는 있었지만, 처리 중 발아가 일어나지 않았고, 발아율을 높이며, $T_{50}$을 단축시킬 수 있는 처리로 왕과 마니따 품종은 carrier와 수분의 배율이 1:3에서 7일이었다. 나머지 10 품종은 1:7의 비율에서 3일이 좋았다. 종가집 품종은 다른 품종에 비해 처리기간과 수분배율에 따라 발아율과 $T_{50}$이 불규칙한 경향을 나타낸 품종으로 조사되었다. 처리온도는 $15^{\circ}C$에서 $35^{\circ}C$로 설정하여 조사한 결과, 처리 중 유근돌출의 억제와 발아성 향상에 안정적인 처리는 $20^{\circ}C$인 것으로 조사되었다.
