Abstract

Effects of cutting media on shooting and seedling characteristics were investigated to determine productivity of seedling by root cuttings of lacquer tree. Shoots developed at 3 weeks after cut planting on PV (peat moss : Vermiculite : 1 : 1), PVS (peat moss : Vermiculite : Sand : 1 : 1 : 2) and PVSC (peat moss : Vermiculite : Sand : Clay loam : 1 : 1 : 2 : 2) media, and shooting rate was the highest in PVSC medium at 10 weeks after cut planting among the treatments. Shooting numbers per scion on PH and PVC media were 2.2 but those on HSC medium was 1.3, which was not significantly different among media. PVSC medium was suitable to use the root cuttings of lacquer tree as it meets the qualifications requirements. Seedlings on PVSC medium were excellent to transplant in field as tree height, branch number, leaf number, stem diameter and leaf area were good.

옻나무 근삽에 의한 묘목의 생산성을 향상시키기 위하여 7종류의 삽상배지를 공시하여 신초발생율과 묘소질을 조사하였다 삽상배지는 PV(peatmoss vermiculite = 1 : 1)와 PVS(peat moss : vermiculite : sand = 1 : 1 : 2) 처리구에서 3주 후부터 신초가 발생되었고, 삽 식 10주 후의 신초발생율은 PVSC(peatmoss : vermiculite : sand : clay loam = 1 : 1 : 2 : 2)배지에서 80%로써 가장 높았다. 삽수당 신초형성수는 PH와 PVC 삽상배지가 2.2개로써 가장 많았고 HSC 삽상배지 는 1.3∼1.5개로써 가장 적었으나 통계적인 유의차는 인정되지 않았다. Peatmoss, vermiculite, sand 및 clay loam을 각각 1:1:2:2 (v/v/v/v)로 혼합한 PVSC 삽상배지가 옻나무 근삽의 삽상배지로 이용하기에 양호하였으며, 수장, 분지수, 엽수, 경직경 및 엽면적 등의 묘소질 역시 양호하여 본포에 이식하기에 적당하였다.
