Abstract

This research was done to identify the mass propagation method in winter daphne (Daphne odora Thunb) using its softwood cuttings and to investigate its plant characters established at different light and soil conditions as an indoor plant. Cuttings from winter daphne were taken and grown in different treatment consisted of rooting media (perlite, vermiculite, perlite + vermiculite (1 : 1) and commercial horticulture media soil), indole butyric acid (IBA) hormone concentrations (0, 100, 500, 1000 ppm and Rootone) and date of cutting. Transplants were grown at different light intensities (100, 1000, 2500 lux and control) and growing media. Results showed that cuttings grown in perlite + vermiculite (1 : 1) gave higher percentage (100%) rooting. Cuttings treated with Rootone and IBA 100 ppm showed good rooting growth and cutting taken in June, 25 gave the highest rooting (96.7%). The best plant growth obtained at 1000 lux (56~60 ${\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$) followed by 2500 lux (125~130 ${\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$) and scoria mixed with commercial horticulture media soil showed better growth of transplants.

본 실험은 자생식물인 서향의 실내 분화로의 도입을 위해 대량 번식 및 광, 토양 조건 구명 실험을 수행하였다. 서향의 대량 번식을 위해 적합한 삽목 상토, 발근촉진제의 농도, 삽목 시기를 찾는 실험을 하였고, 실내로 도입하기 위해 인공광 처리(100, 1000, 2500lux)와 분화상토처리(원예용 혼합상토(바로커), 펄라이트 + 원예상토(1 : 1), 송이 + 원예상토(1 : 1), 마사토 + 원예상토(1 : 1), 모래 + 원예상토(1 : 1))를하였다. 삽목 상토 선발하기 위해 펄라이트, 버미큘라이트, 펄라이트와 버미큘라이트 혼용(1 : 1), 원예용상토 처리를 한 결과에서는 펄라이트와 버미큘라이트 혼용(1 : 1)처리 구에서 발근율이 93.3% 가장 우수하였다. 발근촉진제를 농도별로는 루톤과 IBA 100ppm 처리에서 뿌리 생육이 가장 양호하였다. 녹지삽 시기는 7월에 하는 것이 발근율이 96.7%로 우수하였다. 화분 이식 후 1000lux 이상의 광 조건에서 생육이 가장 좋았으며, 분화용 상토로는 제주 송이와 원예용 상토를 혼합한 토양에서 생육이 가장 좋았다.
