摘要
본 연구는 경남에 자생하고 있는 100-600년 추정 노거수 및 보호수 왕버들의 생육특성을 분석하고, 상토에 따른 삽목증식의 영향을 구명하였다. 노거수 및 보호수 왕버들 6개체는 마을형 4개소, 하천형 주변 1개소, 들판형 1개소에 자생하고 있었다. 삽목증식은 10가지 상토에서 실시하였으며, 모든 상토에서 삽목묘의 생존율은 93%이상이었다. 삽목묘의 묘고 생장이 가장 좋았던 상토는 시판 바이오상토(CBS, mean=60.01 cm)였으며, 다음으로 혼합상토(VPMP, mean=42.95 cm), 피트모스(PM, mean=41.81 cm) 순이었다. 근원경의 생장은 상토에 따라 심한 차이를 보였으며, 신초는 1-4개 형성되었다. 삽목묘의 뿌리길이는 묘고 생장이 좋았던 상토였던 CBS와 VPMP에서 20 cm 이상 생장하였다. 상토의 물리화학적 특성을 조사한 바, 왕버들의 삽목에는 보습력과 통기성이 양호하며, EC값이 높은 약산성의 상토가 적합한 것으로 나타났다. CBS와 VPMP 상토는 노거수 및 보호수 왕버들의 삽목증식에 적합한 상토로 나타났다. 【Old growth and protected-trees are worth history and culturally in Korea. This research carried out to investigate habitat characterization and the vegetative propagation methods of Salix chaenomeloides(100-600 years old trees) in Gyeongsangnamdo Province. It has been preserved in good and grow naturally in area surrounding village(4 trees), riverside(1 tree) and field(1 tree). Cutting from old growth and protected trees was conducted using 10 kinds of bedsoils. It was survived above 93% in all bedsoils. Growth of cuttings is a distinct difference according to bedsoils and tree ages. Growth of cutting was high on CBS, followed mixed bedsoils(VPMP) including vermiculite, peatmoss and perlite. Root collar diameter was difference depend on tree ages and bedsoils. All trees are produced 1 to 4 branch. Root growth of cutting was 20 cm on CBS and VPMP, which is the best shoot growing on cutting. Bedsoil with physico-chemical characteristics of high moisturizing ability, high air permeability, high EC value and slightly acid may be suitable for efficiently cutting propagation of old growth and protected S. chaenomeloides. CBS and VPMP bedsoil are favorable for propagating this species by cuttings.】
