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.

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 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.

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.

한국산 쪽파의 품질 향상을 위해 7개 지역의 쪽파 종구로 재배된 쪽파에 대한 이화학적 특성 분석을 실시하였다. 일반 성분 분석 결과, 쪽파의 수분 함량은 예천 쪽파, 조단백 함량은 제주도 쪽파, 조지방 함량은 예천 쪽파의 함량이 가장 높게 나타났다. 조회분 함량은 중국 쪽파가 가장 높았고, 환원당 함량은 덕적도 쪽파의 함량이 가장 높게 나타나 유의적 차이를 나타냈는데, 총당 함량은 0.36~0.41% 수준으로 유의적 차이가 없었다. 줄기 부분에 대한 경도는 시료 간에 유의적 차이가 없었고, 잎의 경도는 예천 쪽파가 가장 높았다. 수소공여능은 예산 > 중국 > 무안 > 예천 > 제주도 > 안면도 > 덕적도의 순으로 나타났다. 무기질은 K, Ca, P, Mg, Na 등 의 순으로 함량이 감소하였고, 특히 예산 종구로 재배된 쪽파의 함량이 높은 것으로 나타났다. 쪽파의 구성 아미노산은 18종 중 17종이 분석되었으며, 이중 glutamic acid의 함량이 가장 많았다. 매운맛을 나타내는 pyruvic acid 함량은 제주도 종구 재배 쪽파가 가장 높았고, 중국산 종구 재배 쪽파가 가장 낮게 나타났다. 이와 같은 결과로 종구산지가 다른 7가지 쪽파의 이화학적 특성은 유의적 차이가 있는 것으로 확인되었으며, 국내산 쪽파 및 종구의 품질향상을 위해 종구에 따른 국내산 쪽파의 생리활성에 대해서 더 깊은 연구가 필요하다고 사료된다.

Hydroxyurea (HU), a DNA synthesis inhibitor, was tested as synchronizing agent in root-tip meristem of Allium wakegi. Roots were treated with 2.5mM HU for 14 h to accumulate meristem root-tip cells at the G1/S interface. After release from HU block, the cells re-entered the cell cycle with a high degree of synchrony. Synchronized mitotic frequency of A. wakegi was 22.7%, which was about 3.9 times as high as that of the control. The highest metaphase index(23.0%) was obtained when, 6 h after release from the HU block, the roots were treated with 0.05% colchicine for 2 h. Modifying various Giemsa staining protocols defined for animals and a few plant species, G-bands were visualized at prometaphase and metaphase chromosomes of A. wakegi. The higher degree of chromosome condensation, the less differential bands could be resolved. This is the first demonstration introduced partial mitotic synchronization into G-banding in plant.

BACKGROUND: This study was conducted to evaluate the residual characteristics and safety assessment of αcypermethrin and deltamethrin in minor crops, chives and spring onion cultivated in greenhouse. METHODS AND RESULTS: The insecticides α-cypermethrin 2% EC and deltamethrin 1% EC used in the experiment were diluted 1,000 times and then sprayed on chives and spring onion twice with 1-week intervals at 0, 7, 14, and 21 days before harvest. The residual insecticides were extracted from the minor crops using QuEchERS method and analyzed by GC-MS/MS. The average initial residues of α-cypermethrin and deltamethrin in chives after 21 days decreased from 2.74 to 0.82 mg/kg and 1.12 to 0.16 mg/kg, respectively. Similarly, in spring onion the residues after the same periods decreased from 0.26 to <0.01 mg/kg for α-cypermethrin and from 0.07 to <0.01 mg/kg for deltamethrin. CONCLUSION(S): The PHIs (pre-harvest intervals) for α-cypermethrin and deltamethrin in chives are recommended as 14 days before harvest with twice applications of the pesticides, whereas for α-cypermethrin in spring onion PHI of 7 days before harvest is recommended with 3 times of applications and PHI of 21 days for deltamethrin. The theoretical maximum daily intakes of cypermethrin and deltamethrin were 68.8% and 64.2%, respectively, indicating that residues of both compounds did not pose considerable health risks to consumers.
