비비추 나물 자생지의 생태환경과 근권미생물상 = Ecological Environment and Rhizosphere Microflora in the Native Soil of Purple-Bracted Plantain Lily for Wild Vegetables

다국어 초록 (Multilingual Abstract)

This study was conducted to investigate into the ecological environments and the soil
microflora of purple-bracted plantain lily (Hosta longψes Matsumura) for wild vgetables. Native soil textures of purple-bracted plantain lily were in the order of sandy loam (SL) > loam (L) > clay loam (CL). pH in soil was relatively acid by 4.8, electric conductivity was 0.08mS/cm, and organic matter content was 0.08g/kg. CEC was measured by 100.8cmol(+)kg-1 and available phosphate was 103.4mg/kg. Contents of exchangeable cations in terms of potassium, calcium, and magnesium were measured by 0.33cmol(+)kg-1, 2.26cmd(+)kg-1, and 0.87cmol(+)kg-1, etc. Diumal changes in the air temperature of the natives were 15 to 20℃, that temperature differentia1 was relatively little compared with that in open field by 15 to 30℃. Relative humidity in the natives were much more humid by 60 to 80% compared with that in open field by 35 to 85%. Light intensity in the natives and the open field at ten o’clock were 2,300μmol/㎡/sec. and 1,750μmol/㎡/sec. Total number of soil microorganisms were 8.4x107 c.f.u./g. Mycorrhiza1 spore densities over 500μm， 355-500μm，250~354μm, 107~250μm and 45~106μm were 0.8, 1.3, 2.1, 38.1, and 110.0 respectively. Mycorrhizal root infections by vesicle and hyphae were 17% and 6%. However, arbuscules in the roots were not shown.
