부패는 콩나물 재배에서 극복하여야 할 문제중의 하나이다. 본 연구는 콩나물 재배에서 부패완화용으로 식품첨가물의 이용 가능성을 검토하고자 은하콩, 풍산나물콩 및 오리알태를 공시품종으로 식품첨가물의 종류(acetic acid, propionic acid)와 농도(0, 0.1, 0.2%)가 콩나물의 생장과 형태, 병반 형성, 처리비용에 미치는 영향을 조사하기 위하여 실시하였던 바 그 결과를 요약하면 다음과 같다. 1. 상품화가 가능한 하배축 길이가 4cm 이상의 비율은 오리알태에서 가장 높고 은하콩에서 가장 낮았고, 식품첨가물 종류간에는 차이가 없었던 반면, 처리농도가 높을수록 증가하였다. 2. 하배축은 은하콩과 오리알태에 비하여 풍산나물콩에서 길었으며, 하배축 중간부분은 풍산나물콩과 오리알태에 비하여 은하콩에서 굵었다. 그러나 이들 하배축 길이와 직경은 식품첨가물 종류와 처리농도간에는 차이가 없었다. 3. 생산수율과 관련된 개체당 전체 생체중은 은하콩과 풍산나물콩에 비하여 오리알태에서 많았던 반면, 식품첨가물 종류와 처리농도간에는 차이가 없었다. 4. 자엽에 형성된 병반수는 식품첨가물 종류간에는 차이가 없었던 반면, 이들을 처리하지 않는 것보다는 처리할 경우 감소하였다. 5. 처리비용을 고려할 경우 acetic acid보다는 propionic acid를 이용하여 종자소독을 실시하는 것이 경제적인 것으로 분석되었다. Decay during soybean sprout culture detracts their quality as well as increases their production costs. This study was done to determine the effects of acetic and propionic acids on growth and morphological characters of the sprouts. The soybean seeds of 3 cultivars (cv. Eunhakong, Pungsannamulkong and Orialtae) imbibed for 2 minutes at their different concentrations (0, 0.1 and 0.2%) were soaked for 6 hours in 4 ppm BA solution after the first 5.5 hour water imbibition and 0.5 hour aeration, and cultured at $20^{\circ}C$. On the 6th day, harvested soybean sprouts were classified into 4 categories on the base of hypocotyl length;>7cm, 4 to 7cm,<4cm and not germinated, and their morphological characters, fresh weights, lesion spots on cotyledons were measured or analyzed. The stronger concentration the higher rate of longer than 4cm although there was no significant difference between the two acids. Pungsannamulkong showed the longest hypocotyls but Eunhakong did the thickest ones, and Orialtae did the greatest total fresh weight, in which all the characters were not influenced by the two acids and their concentrations. Lesion spots on the cotyledons were equal to the two acids although less in their treatments than in no treatment. Utilization of propionic acid was more desirable Dan acetic acid through their treatment cost analysis.

전래적으로 자가 소비용 숙주나물은 저장기간을 늘이기 위하여 탈수시켜 왔다. 본 연구는 생산된 숙주나물의 수분함량과 밀접하게 연관된 수확당일의 관수가 제품의 저장성에 미치는 영향을 파악하고자 수확 12시간 전부터 관수를 중단하거나 계속 관수하는 방법으로 생산된 숙주나물을 5일간의 저장중에 일어나는 형태 및 무게의 변화를 조사한 결과를 요약하면 다음과 같다. 1. 관수하지 않은 것에 비하여 계속 관수하여 재배한 숙주나물은 저장 3일 후까지 수분 함량이 높은 것으로 나타났다. 2. 수확당일 관수 유무에 관계없이 개체당 형성된 세근수, 하배축 및 뿌리 길이, 건물중은 차이가 없었던 반면, 관수하지 않은 것에 비하여 관수할 경우 하배축 중간부분은 굵었으나, 개체당 자엽과 하배축의 무게 증가로 전체 생체중은 많았다. 3. 하배축과 뿌리의 명도 및 색도 a, 하배축의 전단력은 수확당일 관수 유무간에 차이가 없었던 반면, 하배축 색도 b만 관수를 하지 않을 경우 높았다. 4. 수확당일 관수하지 않을 경우 저장 후 3일부터는 개체당 세근수가 감소하였으며, 하배축과 뿌리 길이, 하배축 직경, 각부위 및 전체 생체중도 개체당 세근수와 유사한 경향을 보였다. 5. 수확당일 관수하지 않을 경우 하배축의 전단력은 저장 5일차부터, 하배축과 뿌리의 명도는 저장기간이 길어질수록 감소하였다. Traditionally mungbean (Vigna radiata L.) sprouts has been stored after dehydration to decrease their decay. The study was done to determine the effect of watering for final 12 hours of harvest day on morphological characters and color of mungbean sprouts. The seeds of cv. Zhong Lu 1 were soaked in 50 ppm BA solution immediately before 4 hour aeration and then cultured for 6 days, when water-supplied for final 12 hours or not. After packaged with PE envelops, the sprouts stored 5 days at 8~circC , and their morphological characters, fresh and dry weights, and colors were measured everyday. Compared to non-water supplied, water supplied sprouts had thicker hypocotyl diameter in middle part, and higher total fresh weight due to increment of cotyledon and hypocotyl ones although the two sprouts did nearly same in other characters. Only nonwater supplied sprouts showed higher color b value in hypocotyl than water supplied ones although there were not significant differences between them in other color-related characters, meaning that the latter ones were more rapidly decayed during their storage. In non-water supplied sprouts, number of lateral roots, hypocotyl and root lengths, total fresh weight, brightness of hypocotyl and root was decreased since 3 days after storage but cutting resistance of hypocotyl was done since 5 days.

Traditionally mungbean (Vigna radiata L.) sprouts has been eaten soon after washing. The study was carried out to measure the effect of washing before packaging on morphological characters and color of mungbean sprouts. The seeds of cv. Zhong Lu 1 were soaked in 50 ppm BA solution immediately before 4 hour aeration and then cultured for 6 days. The sprouts were washed immediately before packaged with PE envelops or not, and then stored 5 days at 8℃. Their morphological characters, fresh and dry weights, and colors were measured everyday. Compared to washed, nonwashed sprouts had more lateral roots although the two sprouts did nearly same in hypocotyl and root lengths, hypocotyl diameter, fresh and dry weights. Non-washed sprouts, moreover, showed higher brightness in hypocotyl and root and cutting resistance in hypocotyl although there were not significant differences in color a and b, meaning that the latter ones were more rapidly changed during their storage. In non-washed sprouts, number of lateral roots, hypocotyl length and diameter, total fresh and dry weights were nearly same up to 3 days and afterward were declined. Brightness and color b of hypocotyl were decreased with increased storage period although cutting resistance of hypocotyl was since 3 days after storage.

Storage conditions of selling mungbean sprouts should affect their marketability. The study was done to examine the effect of light quality (blue, green, yellow, red, far-red) on greening period, shape, fresh and dry weights of mungbean (cv. Zhong Lu 1) sprouts for 5 days to get some information on designing their various polyethylene envelops with different colors. Periods taking to green were 2 to 3.5 days in blue, red and far-red lights but longer than 6 days in green and yellow lights. Yellow lights had the longest total length adding hypocotyl and root, and blue light did the widest hypocotyl diameter while all light treatments showed similar lateral roots for the period. Total fresh and dry weights were the highest in red light but the least in far-red light. Their lengths and weights in green and yellow lights showing the longest periods for their greening declined with increased storage periods but showed no difference between them, meaning that the envelops should be designed mainly by green and yellow colors.

홍동오,이창우,김홍영,강진호,유영섭,신성철 韓國藥用作物學會 2006 한국약용작물학회지 Vol.14 No.4

개화 이후 고사하는 일임성 식물인 바위솔은 가을철에 집중되는 자연산의 출하시기와 중복되지 않도록 비가림 하우스에서 인공재배되고 있다. 본 연구는 하우스 시설로 인한 차광 (무차광, 35, 55, 75, 95% 차광)이 바위솔의 생장 및 개화에 미치는 영향을 파악하고자 실시되었던 바 그 결과를 요약하면 다음과 같다. 1. 초장, 화서장, 엽과 포엽수 및 경직경은 광도가 가장 약한 95% 차광시 가장 짧고, 적거나, 가늘었던 반면, 여타 차광 처리간에는 차이가 적다 할지라도 차광이 심할수록 줄어드는 경향을 보였다. 2. 엽과 포엽중, 경중, 근중, 지상부중, 전체건물중은 무차광에서 가장 많았으며 차광이 심할수록 감소되는 경향을 보였다. 3. 형성된 소화수는 건물중과 같이 무차광에서 가장 많고 차광이 심할수록 감소되었으나, 95% 차광시 아주 적었다. 4. 차광처리로 소화가 개화된 개체는 관찰되지 않아 광도가 제한되는 시설하우스에서 여타 처리를 통하여 바위솔의 인공재배는 가능할 것으로 판단된다. Orostachys japonicus, a monocarpic plant, is artificially grown in greenhouses. The study was carried out to examine the effect of shading (0, 35, 55, 75, 95%) on growth, morphological characters, and flowering. The treatments were done on August 25 and afterward samples were taken every 2 weeks until October 20, in which growth, morphological and flowering related characters were measured. With severer shading plant height, inflorescence length, number of leaves including bracts and stem diameter were decreased although severely declined in 95% shading treatment. Leaves and bracts, stem, root, shoot and total dry weights increasingly declined with severer shading. Florets formed on the inflorescence showed similar response to the shading treatment as plant height did. Flowering of the florets was not observed throughout all the sampling period, meaning that different light intensities by shading did not affect their flowering.

‘MS-CDE’와 ‘VFR’의 고정된 계통을 교배하여 특성 및 수량이 우수한 F1 품종인 ‘TY알토랑’을 육성하였다. ‘TY알토랑’의 주요특성은 TMV, TYLCV, 근부위조병, 잎곰팡이병에 내병성이며, 2~3월, 7~9월에 정식하는 품종으로 숙기는 중조생종으로 평균과중 225 g 내외의 고구형의 완숙 대과종토마토이다. 경도가 강하여 저장성이 우수하고 과형이 정연하며, 착과가 안정되어 수량성이 높다. 또한 초세가 강하면서 이상줄기 발생이 적어 재배가 안정적인 품종이다. ‘TY Altorang’ was developed from a cross between ‘MS-CDE’ and ‘VFR’ in 2009. The cultivar has multi-disease resistances against Tobacco mosaic virus(TMV), Tomato yellow leaf curl virus(TYLCV), Fusarium crown and root rot and Leaf mold disease. Additionally, this cultivar produces larger fruit set resulting in higher fruit harvest. Fruit shape is fair and uniformed ovate type with an average fruit weight of 225 g as a beef-steak type tomato, and the fruit presents longer shelf-life due to higher fruit firmness. The early and medium-maturing variety can be transplanted in February to March, or July to September. Medium-strong plant-vigor and low occurrence of creased stem allow, relativey easy cultivation.

관수방법과 BA 처리농도가 숙주나물의 생장과 형태에 미치는 영향

류영섭,홍동오,이창우,김홍영,강진호 韓國作物學會 2006 Korean journal of crop science Vol.51 No.3

숙주나물의 세근 발생 억제용으로 이용되고 있으나 인체에 대한 유 무해가 밝혀져 있지 않은 BA의 처리량을 경감시킬 수 있는 가능성을 탐색하고자 중록l호를 공시재료로 BA 농도 (0, 10, 20, 30, 40, 50 ppm)를 달리하여 5 시간 침종시킨 후에 상면살수 방식과 하면담수 방식으로 6 일간 재배한 숙주나물의 생장과 형태를 조사하였던 바 그 결과를 요약하면 다음과 같다. 1. 개체당 세근수는 상면살수와 하면담수 방식 모두 20 ppm에서 30 ppm으로 처리농도가 증가될 경우 급격히 감소하는 경향을 보였다. 2. 관수방법에 관계없이 BA 농도가 증가할수록 하배축, 뿌리 및 전체 길이는 짧아졌던 반면, 하배축과 뿌리 길이의 비율과 하배축 직경은 커지는 경향을 보였다. 3. 개체당 전체생체중은 상면살수 및 하면담수 방식 모두 20 ppm 까지 BA 처리농도가 증가될수록 증가되는 경향을 보였으며, 이러한 증가는 주로 하배축의 증가에 기인되었다. 4. 하면담수 방식에 비하여 상면살수 방식으로 재배할 경우 하배축과 뿌리 길이도 길고, 개체당 전체생체중도 많아 숙주나물의 생장은 하면담수 방식보다는 상면살수 방식에서 촉진되는 것으로 나타났다. Utilization of synthetic benzyladenine (BA) for bean sprout production should be reduced or minimized because of elevating production cost and not ascertaining action mechanism to human body. The study was done to compare the effects of BA concentrations under different watering methods (overspraying or underwatering) on growth and morphological characteristics of mungbean sprouts. Seeds of cv. Zhong-Lu 1 were soaked for 5 hours in the solutions with different BA concentrations (0, 10, 20, 30, 40, 50 ppm) before 4 hour aeration, and then were cultured for 6 days by both watering systems. Their morphological characters, fresh and dry weights were measured. Regardless of watering methods, lateral roots were sharply dropped over 30 ppm BA concentrations, and hypocotyl, root and total lengths were shortened with increased BA concentrations although ratios of hypocotyl to root lengths and hypocotyl diameters were enlarged with their increment. Total fresh weights were increased up to 20 ppm in overspraying method but up to 30 ppm in underwatering method mainly due to increment of hypocotyl fresh weights. The sprouts were faster grown in overspraying method than in underwatering method because the former showed longer lengths of hypocotyl and root, and total fresh weights.
