본 연구는 흑쌀보리 육성을 위해 Otello, 흰쌀보리 및 늘쌀보리 등 3품종으로 교배하고 계대 육성하여 F7세대의 각 형질을 분석한 결과는 다음과 같다. F7세대에 대한 상관의 정도는 단백질 함량과 β-glucan 함량 간에서, β-glucan 함량과 까락 길이 간에서, β-glucan 함량과 1000립중 간에서, 이삭 길이와 1000립중 간에서 각각 유의하였다. 광의 유전력은 모든 형질에서 0.9292 이상으로 높았다. 경로계수 분석에서 1000립중에 관여하는 직접효과는 단백질 함량, β-glucan 함량, 이삭 길이가 정의 효과를 보였으며, 간접효과도 단백질 함량, β-glucan 함량, 이삭 길이의 관여 조합이 정의 효과를 보였다. 선발지수는 단일형질에서 까락 길이와 단백질 함량이 정으로 높았다. 3개 형질 및 4개 형질의 조합에서는 단백질 함량과 까락 길이의 관여가 모두 정으로 높았다.

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.

With treatment of Kitosan, Wood vinegear and EM(effective microoganism) which farmers call it as substance in fertilizing, conditioning and disease control ubstances, authors in vestigated on microorganisms change in soil and ealy growth characteristics of tomato. The results were summarized as follows : Among foliar application of kitosan, wood vinegear and EM(effective microoganism) treatments diluted by chitosan 500 times solution level was effective considering growth of tomato as compared other dilutions and control plot. Change of microorganism number in the soil for cultivation of tomato was increased with microorganism treatment plot as compared with control plot. Specially chitosan 500 times solution level showes the most significant effect.

This study was conducted to investigate the effect of microbial product on microorganisms in soil and the growth of leaf lettuce. The test material were treated with chitosan, wood vinegar and EM activity liquid, and treatment concentration was 50 times solution and 100 times solution level with foliar application. The results were summarized as follows : Among foliar application of microorganisms treatments diluted by chitosan 100 times solution level was effective considering growth of leaf lettuce as compared other dilutions and control plot. Change of microorganism number in the soil for cultivation of chinese cabbages and leaf lettuce was increased with microorganism treatment plot as compared with control plot. Specially chitosan 100 times solution level showes the most significant effect.

This study was conducted to investigate the effect of different concentrations of microbial products on growth of chinese cabbage and microorganisms in soil. Two different levels of microbial products, such as 50 times and 100 times diluted solutions of chitosan, wood vinegar and EM activity liquid, were treated for foliar application. The results were summarized as follows : Among foliar applications of microbial products, 100 times diluted solution of chitosan was effective on growth of chinese cabbage comparing to other levels of dilutions and untreated control plot. The number of microorganism in the soil tended to increase under the treatment of microbial products compared to control plot. Especially, the numbers of the bacteria and actinomycetes were estimated 73.67×10³ CFU/g and 34.00×10³ CFU/g, respectively, under the treatment of 100 times diluted solution of chitosan.

생균제로서 가능성 있는 유산균의 선별을 위해 발효식품인 동치미로부터 분리된 균주들의 내산성, 내담즙성, 내췌장 액성 및 유해균 억제능을 조사하였다. 특히 분리된 균종 중에서 FF-3가 인공위액과 담즙산에 대한 높은 내성을 나타내었을 뿐만 아니라, Salmonella sp. 과 Escherichia coli에 대하여 높은 항균 활성을 나타내었다. FF-3유래 박테리오신은 그람 양성 및 음성 세균에서 넓은 항균 범위를 나타내었다 본 연구에서 최종선별

This study the effects of the application of organic farming materials on the soil physicochemistry property and plant growth, yield and components of Tomato were compared with conventional culture. The results obtained from the experiment are summarized as follows： 1. The effect of soil chemical properties after application organic farming materials, The amounts of pH and O.M. in N, P, K treated plot were few of change, To the contrary, fermentation compost and microorganisms fermentation compost treated plot were some increase, Amount of P₂O₅, Ca and K increase in comparison with the N, P, K treated plot. 2. Changes of soil microbial after application organic farming materials, The number of bacteria, actinomycetes and fungi in N, P, K treated plot were appeared definite direction. to the contrary, The number of bacteria and actimycetes in fermentation compost and microorganisms fermentation compost treated plot showed the increased tendency, The number of fungi showed the decreased tendency. 3. Effect of organic farming materials application on the growth and yield of tomato was superior in order of microorganisms fermentation compost plot＞chemical fertilizers plot＞fermentation compost plot. especially, chicken manure + microorganisms fermentation compost treated plot was the highest. 4. Effect of organic farming materials application on the components of tomato were not different.
