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.

공시 농약인 "스미렉스 수화제"를 알타리무에 살포한 다음 2시간 후에 각각 지하수, 키토산 500배액, 및 목초액 1,000배액을 골고루 엽면살포하였다. 그리고 공시재료 살포 2시간 경과 후, 1일 경과 후, 7일 경과 후 및 15일 경과 후에 각각 시료를 채취하여 알타리무 체내의 procymidone 잔류농약을 분석한 결과는 다음과 같다. 1. 알타리무 체내의 procymidone의 검출농도를 측정한 결과 농약만 살포한 무처리구인 대조구에 비해 지하수, 키토산 500배액, 및 목초액 1,000배액 처리구에서 잔류농약인 procymidone의 검출농도가 낮게 나타났으며, 특히 키토산 500배액 처리구에서는 평균치 보다 낮게 나타났다. 2. 알타리무 체내의 procymidone의 분해율을 측정한 결과 키토산 500배액 처리구 및 목초액 1,000배액 처리구에서 잔류농약인 procymidone의 분해율이 비교적 높게 나타났으며, 공시 엽면처리 재료간에는 큰 차이는 없었으나 대체적으로 키토산 500배액 처리구에서 분해율이 높게 나타났으며, 시간경과에 따른 평균 분해율은 공시재료를 엽면살포하고 7일이 경과한 후에 급격히 증가하는 것으로 나타났다. 3. 지하수, 키토산 500배액 및 목초액 1,000배액을 엽면살포한 후 매일 달관조사를 하여 생육장해 및 비해조사를 한 결과 본 시험 농도에서는 비해가 없는 것으로 조사되었다. For this study, Smilex powder, a pesticide, was sprayed on the Altari radish, and then underground water, Chitosan solution (${\times}$500), and wood vinegar solution (${\times}$1000) were evenly sprayed on the Altari radish respectively. Samples of Altari radishs for residual pesticide analysis were taken two hours, 1 day, 7 days, and 15 days after treatments, and the detectable concentration and degradability of procymidone, the pesticide residue, were measured. The results obtained are as follows: 1. When detectable concentration of procymidone within the altari radish was measured, treatment plots sprayed with underground water, Chitosan solution (${\times}$500), and wood vinegar solution (${\times}$1000) were found to show lower detectable concentration than the non-treatment plot which was sprayed with pesticide only. Especially, the treatment plots sprayed with Chitosan solution (${\times}$500), and with wood vinegar solution (${\times}$1,000) showed lower values than the average. 2. When the degradability of procymidone within the Altari radish was measured, the plot treated with Chitosan solution (${\times}$500) and the plot treated with wood vinegar solution (${\times}$1,000) were found to have relatively higher degradability of procymidone. There were not much differences among testing materials in the degradability of residual pesticides. However, the plot treated with Chitosan solution (${\times}$500) showed higher degradability. In terms of average degradability with time, degradability increased sharply 7 days after the foliar application of testing materials. 3. When the daily far-sighted view survey was conducted in order to find out growth disorder and damage on the Altari radish plants by the treatment of un-derground water, Chitosan solution (${\times}$500), and wood vinegar solution (${\times}$1,000), no symptomatic physiological disorders was observed on all the plants tested during the whole growing season at the tested concentration level.

본 연구에서는 유기농자재인 키토산, 목초액 및 EM 활성액 등을 공시재료로, 배추 정식 전에 100배액 토양관주 처리하고, 배추 정식 후 15일 간격으로 엽면살포 농도를 100배액과 1,000배액으로 3회 엽면살포한 후 배추의 생육 및 토양 미생물상의 변화에 대해 분석하였다. 유기농자재 처리에 따른 배추의 생육특성은 대조구에 비해 유기농자재 처리구에서 생육이 양호하게 나타났으며, 유기농자재 간에는 키토산 처리구에서 양호하였고, 특히 키토산 1,000배액 처리구에서 생육이 양호하였으며, 주중이 5.60 ㎏으로 가장 무거웠다. 유기농자재 처리에 따른 토양 미생물상 변화는 대조구에 비해 유기농자재 처리구에서 세균, 트리코데마 및 방선균수은 증가한 경향을 보였고, 사상균수는 약간 감소한 경향을 보였으나 처리간 일정한 경향은 없었다. 유기농처리구 간에는 키토산 1,000 배액 처리구에서 세균, 트리코데마 및 방선균수가 가장 많이 증가하였다. This study was conducted to investigate the effects of organic materials, chitosan, wood vinegar, and EM active solution, on soil microbial and growth in Chinese cabbage. The organic materials were treated with chitosan, wood vinegar, and EM (effective microoganism) active solution, and the treatment concentration was 100 times solution and 1,000 times solution level with foliar application. The results are summarized as follows: Among foliar application of organic materials treatment plot[?], with 1,000 times solution level of chitosan was effective in inhibiting microbial growth in Chinese cabbage compared to other plots and control. The microorganism number in the soil for cultivation of Chinese cabbage increased with organic materials treatment plot as compared with control. Especially, 1,000 times solution level of chitosan showed the most significant effect.

This study aims to examine the morphological characteristics of tea leaves by its growing areas and countries. We collected tea leaves from 7 areas in Korea and overseas. We investigated classification of morphological characteristics, analyzing phenotypic, and genotypic correlations coefficient of the tea leaves. In classification of morphological characteristics, the tea leaves from Gurye had the highest values in leaf length, size, and stalk length, while the tea leaves from Gangjin had the highest values in leaf width, fresh leaf weight, and dry leaf weight. In case of Wuishan, China, it showed the lowest values in leaf length, width, size, and stalk length. The tea leaves from Korea had the largest size, whereas the tea leaves from China had the smallest one. In term of character correlation, significant correlations were showed in several aspects respectively: between leaf length and dry leaf weight (0.6694**), between leaf width and dry leaf weight (0.7393**), between leaf area and dry leaf weight (0.7191**), also between fresh leaf weight and dry leaf weight (0.9388**). In case of leaf weight regardless of whether it is a fresh leaf or dry leaf, which has the quantitative character, significant correlations between leaf length and fresh leaf weight (0.7642), between leaf width and fresh leaf weight (0.8411), also between leaf area and fresh leaf weight (0.8146).
