Abstract

To product the edible fresh shoots of Sedum sarmentosum in summer season, 4 local strains were cultivated with cutting propagation under 0, 30, 50, 70, 90% shading. Effect of shading on shoot growth, leaf chroma value, SPAD value, and bitterness were investigated at 35 days after cutting. Plant height, the number of node and leaf stem diameter in $30{\sim}90%$ shading were increased than in the control, and Pohang local strain had little-overgrowth shoot, thicker stem, a few brenches per shoot, and larger leaf compared to the other local strains. Fresh and dry weight under shading were increased than in the control, dry weight of pohang local strain was highest in 50% shading. Hunter L and b values were decreased out of proportion to higher shading rate. SPAD value in $50{\sim}90%$ shading was significantly lower than in the control. The bitterness of fresh shoot was decreased out of proportion to higher shading rate. In Summer season, producing the fresh shoot of S. sarmentosum was excellent in 50% shading, and Pohang local strain among 4 local strains was more stable and good in yield and quality under shading.

여름철 고품질 돌나물 생산을 위하여, 군산, 완도, 완주, 포항 등 4 지방 수집종을 재료로 차광수준(0, 30, 50, 70, 90%)에 따른 생육특성, 엽색 및 엽록순 함량 변화와 쓴맛의 변화를 삽목재배 35일 째에 조사하였다. 차광재배에 따른 초장, 마디수, 엽수, 줄기직경 등의 생육은 무처리보다 증가하였으며, 포항 지방종이 줄기직경이 굵고 곁가지가 적게 발생하며, 잎도 크고 웃자라는 경향이 적어 양호하였다. 생체중 및 건물중도 무처리보다 유의하게 증가하였으며, 건물중은 포항 지역종의 50% 차광에서 가장 높았다. 차광에 따른 엽색의 명도를 나타내는 L, b 값은 차광율이 증가할수록 낮아졌으며, SPAD 값은 50%-90% 차광 하에서 무처리보다 유의하게 감소하였다. 또한 차광재배에 따른 쓴맛의 변화도 차광율에 비례하여 낮아졌으며, 50% 이상의 차광하에서는 약간의 쓴맛만을 느낄 정도로 양호하였다. 따라서 여름철 돌나물 재배시 차광정도는 지상부 생육과 품질면에서 50%가 적합하였으며, 지역종간에는 포항 지방종이 차광재배에 대한 적응성이 높아 수량 및 품질 면에서 양호하였다.
