Optimmum cultivation period was determined for producing seed bulb of Korean native Allium wakegi Araki in vitro in hydroponic culture. The growth gradually increased during cultivation period. In general, plants grown for 5 months produced significantly the highest bulb number and bulb fresh weight per plant. Raising the cultivation period from 1 to 5 months remarkably increased seed bulb yield.

Allium wakegi was cultured shoot tip in the condition of light culture. The Allium wakegi added plant growth regulator was observed of plant regeneration and bulblet formation. Callus Induction and growing rate was the best of 78％ when added alone 2,4-D 0.5mg/L. In the formation of shoot, its regeneration rate was 96％ when added BA 0.5mg/L in the light culture condition. When BA 0.5mg/L and NAA 0.5mg/L mixed and BA 0.5 mg/L and NAA 1.0mg/L mixed, the rates were 99％ and 97％ respectively, and these conditions were suitable for forming shoot. In the formation of roots, when added NAA 2.0mg/L in the light culture condition, the regeneration rate was 90.6 ％ and the roots were abnormal. When added NAA 1.0mg/L, the rate was 82 ％ and the highest. In the formation of bulbs, when BA 05mg/L and NAA 1.0mg/L mixed, the root generantion and its size in the bulbs was the best compare to other treatment experiments.

쪽파의 잎과 인경, 2,4-D 0.5, 1.0mg/L가 첨가된 MS배지에서 배양된 캘러스로부터 아미노산 분석과 항산화활성 을 분석하였다. 총아미노산 분석의 함량은 자연조건상태의 잎에서는 59.779 mg% 함유하였으나 2,4-D 0.5mg/L가 첨가된 배지에서 배양된 캘러스에서는 73.725 mg%를 함유하였으며 그 가운데 Glutamic acid가 26.555 mg%로서 가장 높게 나타났다. 총아미노산 함량에 대한 필수 아미노산의 함량 비율은 자연조건상태의 인경부분이 39.462 mg%를 함유하였고, 2,4-D 0.5mg/L가 첨가된 배지에서 배양된 캘러스에서는 13.072 mg%를 함유하고 있었다.

쪽파의 정단분열조직을 LS기본배지에 zeatin(0.1, 0.5, 1.0, 3.0mg/L)과 NAA(0.1, 0.5, 1.0, 2.0, 5.0mgA)를 단독 및 혼합 첨가시키어 식물체 생산과 인경 형성율을 조사하였다. 정 단분열조직으로부터 신초 분화는 zeatin 0.1, 0.5, 1.0 mg/L 단독처리구와에 zeatin 0.5 mg/L에 NAA 1.0mg/L 혼합첨가구에서 가장 양호한 반응을 보였다. 뿌리분화율은 zeatin 0.5 mg/L에 NAA 1.0mg/L 혼합첨가구에서 가장 좋았다. 분화된 식물체로부터 정상적인 인경형성은 NAA단독첨가보다는 zeatin과의 혼합첨가가 효과적이었다. 특히 NAA 3.0mg/L에 zeatin 1.0mg/L를 혼합시켰을 때 정상적인 인경 형성에 가장 좋은 반응을 보였다.

Allium wakegi Araki was grown at plant spacings of 5, 10, 15, and 20 cm to determine the effect of planting density on the growth and yield. Allium wakegi Araki plants grown at the 5 cm plant spacing had the lowest bulb diameter and bulb weight, while plants at the lowest density (20 cm spacing) had the highest bulb diameter, bulb number, bulb weight and fresh weight. In general, plants grown at narrower spacings produced significantly smaller bulb diameter and bulb weight, but resulted in the highest yields and plants per hectare and lower fresh weights per plant.
