본 연구는 약용 및 관상용 자원으로써 기대되는 산자고의 자생지 환경을 체계적으로 분석하여 재배법 및 생태적 특성에 대한 기초자료 제공을 위해 수행되었다. 자생지 환경은 해발 245 m, 방위는 남향, 자생지 면적은약 49 m2이고, 건조한 양지에서 자생하는 것으로 분석되었다. 관속식물상은 28과 59속 50종 11변종 1품종 등 총 62분류군이 확인되었고 자원식물상은 관상용 23종(37.1%), 식용 43종(69.4%), 약용 34종(54.8%), 기타용 29종(46.8%)으로 분류되었다. 토양요인 분석결과, 산도는 pH 4.9, 유기물함량 4.8%, 유효인산 3.6 mg/kg, 치환성 칼륨 0.5 cmol+/kg, 치환성 칼슘 3.0 cmol+/kg, 치환성 마그네슘 0.8 cmol+/kg, 양이온치환용량 12.3 cmol+/kg, 전기전도도 0.3 dS/m로 나타났다. 화학적 특성간 상관분석결과, 치환성 칼슘과 양이온치환용량이 높은 상관성을 보였다. 산자고의 생육특성은 초장 7.6cm, 엽폭 0.6 cm, 엽장 12.7cm, 화폭 2.8 cm, 화경장 5.4 cm, 엽록소량은 34.7 μg mg-1로 조사되었다. 생육특성간 상관분석 결과, 초장과 화경장이 높은 상관성을 보였다. 토양요인과 생육특성간 상관성 분석결과, 치환성 칼륨과 엽장이 높은 상관성으로 보였으나 이들의 관계는 부적 상관성으로 확인되었다. 생육모형 분석 결과, 엽폭과 치환성 칼륨의 설명력은 약 86.4%, 엽록소량과 치환성 칼륨은 약 83.7%였다.
This study was carried out to offer the raw data on the method of cultivation and ecological characteristic by systematical analysing habitat environment of Tulipa edulis that was expected as medicinal and ornamental resource. The habitat environment was that the altitude was 245 m, the aspect of south, the size of approximately 49 m2, and there was analyzed that Tulipa edulis grew wild in the dryly sunny spot. The vascular plants were summarized as 62 taxa; 28 families, 59 genera, 50 species, 11 varieties and 1 forms, and the resource plants were classified that there were 23 taxa of ornamental plants(37.1%), 43 taxa of edible plants(69.4%), 34 taxa of medicinal plants(54.8%) and 29 taxa of others(46.8%). In the results of soil factors analysis, there showed that acidity was pH 4.9, organic matter content of 4.9%, available P2O5 of 3.6 mg/kg, exchangeable K+ of 0.5 cmol+/kg, exchangeable Ca2+ of 3.0 cmol+/kg, exchangeable Mg2+ of 0.8 cmol+/kg, cation exchange capacity(C.E.C) of 12.3 cmol+/kg and electrical conductivity(EC) of 0.3 dS/m. In the results of correlation analysis between soil factors, exchangeable Ca2+ and C.E.C were highly correlative. The growth characteristics of Tulipa edulis were surveyed that height was 7.6 cm, leaf width of 0.6 cm, leaf length of 12.7 cm, flower width of 2.8 cm, peduncle of 5.4 cm and chlorophyll of 34.7 μg mg-1. In the results of correlation analysis between growth characteristics, height and peduncle were highly correlative. In the results of correlation analysis between soil factors and growth characteristics, exchangeable K+ and leaf length were high relativity but they were confirmed negative relation. In the results of growth model analysis, R-square of leaf width and exchangeable K+ was some 86.4% and that of chlorophyll and exchangeable K+ was some 83.7%.
