본 연구는 우수한 흑쌀보리 육성을 위하여 동아대학교 종합농장 수도포장에서 실시하였다. 시험에 사용된 교배친은 무조성인 흑피맥 Otello, 늘쌀보리 및 흰쌀보리 등 3품종으로 2000년 4월에 교배하여 6월에 채종하였다. 그리고 2001년 F1세대를 거쳐 2002년 F2세대에서 2007년 F7세대까지 12계통을 분리계대육성하여 homo화 시켜 흑쌀보리의 육성의 교배친과 이들 F7세대의 교배조합에 대한 유전력과 상관관계에 대한 연구 결과는 다음과 같다.교배친에서는 유전분산이 환경분산에 비하여 높았으며 유전분산은 천립중이 15.2658로 가장 높았던 반면, 망장이 0.0833으로 가장 낮았고 모든 형질에서 고도의 유의성을 나타내었다. 유전력은 β-glucan이 99.99%로 가장 높았으며 망장을 제외한 각 조사형질에서 95%이상의 높은 수치를 보였다. F7세대의 교배조합에서도 모든 형질에서 고도의 유의성을 나타내었으며, 유전분산에서 천립중이 6.9148로 가장 높았다. 교배친에서 β-glucan 함량과 천립중간에, β-glucan 함량과 망장간에서는 유의한 정의 상관이었고, 수장과 β-glucan 함량간에는 부의 상관을 보였다. F7 세대의 교배조합에서는 천립중과 β-glucan 함량간에서 정의 상관을 보였으나 그 수치는 다소 낮았다.

수은은 장거리 이동특성을 가지고 있어 국제적 공동대응 필요성이 지속적으로 제기되었다. 최근 수은의 관한 미나마타 협약이 채택되었으며, 이에 대한 비준을 추진하고 있다. 수은은 배가스 중에서 가스상, 입자상으로 존재한다. 가스상 수은은 산화수은과 원수수은으로 구분된다. 입자상 수은은 전기집진기, 여과집진기와 같은 먼지 제어장치를 통해 주로 제어된다. 산화수은은 입자상물질에 흡착되어 제어되거나, 습식방지시설에 의해 제어된다. 원소수은은 공정변수들에 의해 산화 및 흡착되어 제어된다. 이와 같이 기존 대기오염 방지시설은 수은의 동시제어(co-benefit)효과를 가지고 있다. 본 연구에서는 미세먼지를 제어하기 위해 개발된 HI-filter에서의 수은 화학종의 거동과 흡착제분사에 따른 영향을 확인하고자 하였다. 석탄 화력발전시설에 설치된 Pilot-scale HI-filter는 배가스 중 미세먼지를 99%이상 제어하였으며, 수은의 제어효율은 66.22%로 나타났다. HI-filter는 산화수은을 입자상물질로 전환시키는 비율을 증가시켰다. 이로 인해, HI-filter후단에서의 수은은 대부분 원소수은으로 존재하였다. 이후 원소수은을 제어하기 위해 HI-filter 전단에서 활성탄과 비산재를 분사하여 수은의 화학종과 수은제어효율을 비교하였다. 활성탄분사 시 원소수은은 활성탄에 흡착되었으며, 입자상수은이 80%이상으로 증가하였다. 이로 인해, 수은의 제어효율은 최대 92%까지 증가하였다. 비산재분사 시 원소수은의 산화반응은 촉진되었으며, 산화수은은 35%까지 증가하였다. 그러나 수은의 제어효율은 61%로 감소하였다. 하지만 HI-filter후단이 습식방지시설에 의해 산화수은은 제어될 수 있으며, 석탄 화력발전시설 전체의 수은제어효율은 크게 상승할 것으로 판단된다.

For this study, Smilex powder, a pesticide, was sprayed on the Altari radish, and then underground water, Chitosan solution (×500), and wood vinegar solution (×1000) were evenly sprayed on the Altari radish respectively. Samples of Altari radishs for residual pesticide analysis were taken two hours, 1 day, 7 days, and 15 days after treatments, and the detectable concentration and degradability of procymidone, the pesticide residue, were measured. The results obtained are as follows: 1. When detectable concentration of procymidone within the altari radish was measured, treatment plots sprayed with underground water, Chitosan solution (×500), and wood vinegar solution (×1000) were found to show lower detectable concentration than the non-treatment plot which was sprayed with pesticide only. Especially, the treatment plots sprayed with Chitosan solution (×500), and with wood vinegar solution (×1,000) showed lower values than the average. 2. When the degradability of procymidone within the Altari radish was measured, the plot treated with Chitosan solution (×500) and the plot treated with wood vinegar solution (×1,000) were found to have relatively higher degradability of procymidone. There were not much differences among testing materials in the degradability of residual pesticides. However, the plot treated with Chitosan solution (×500) showed higher degradability. In terms of average degradability with time, degradability increased sharply 7 days after the foliar application of testing materials. 3. When the daily far-sighted view survey was conducted in order to find out growth disorder and damage on the Altari radish plants by the treatment of underground water, Chitosan solution (×500), and wood vinegar solution (×1,000), no symptomatic physiological disorders was observed on all the plants tested during the whole growing season at the tested concentration level.

Among the treatment plots, the plot treated with wood vinegar + charcoal showed slightly higher values. The contents of minerals in chinese cabbage such as Ca, Fe, K, Mg and Mn were higher in the treatment plots than the control.
