The stock that is the first step for preparation of soups and purees links to the taste of food. Many types of vegetable have been used in stocks, but this study focused on stocks prepared with sweet pumpkin. The stock preparation conditions including the weight of sweet pumpkin, the water volume, and the boiling time at $97^{\circ}C$ were optimized by response surface methodology. The quality characteristics of the resulting stock were investigated. The color, flavor, taste and overall acceptability were dependent parameters. A model equation was proposed with regard to the sweet pumpkin weight, water volume, and boiling time at $97^{\circ}C$. A sweet pumpkin weight of 357.9 to 403.0 g, a water volume of 689.8 to 768.5 mL, and a boiling time of 9.9 to 10.3 min at $97^{\circ}C$ were found to be the optimal stock preparation conditions. The quality characteristics of the sweet pumpkin stock prepared under the optimized conditions were pH 6.64, total acidity 0.18%, soluble solids $2.39\;^{\circ}Brix$, color value (L, 99.07 a, -2.43 b, 11.82), total polyphenol 280.75 mg/L, and electron donating ability 21.32%.

This study was conducted to determine whether Pleurotus ostreatus (oyster mushroom), cultivated in various ratios with herbal extract remnants instead of cotton supplemented with nutrients (the control), improved mycelial growth, mushroom yields and longevity during storage. In addition, we investigated the transfer of medicinal herb components into the mushrooms since they contained non-specific medicinal herbs and their composition could not be controlled. Mushrooms cultivated with 70% and 100% medicinal herb remnants had faster growth rates, higher yields and less failure in the development of the fruit body than the control group. There were no differences in HPLC chromatogram among the methanol extracts of Pleurotus ostreatus in all groups. In addition, glycyrrhizin, an indicative compound of licorice which was a major herb among the herbal remnants, was not detected in any of the extracts. Pleurotus ostreatus that was cultivated with 70% and 100% herbal extract remnants had improved storage longevity in comparison with the control. They exhibited the least weight loss during storage among the groups and they maintained firmness in the stipe and pileus. However, the sources of media did not alter the color difference of the stipe and pileus or the quality index of the outward appearance during storage. In conclusion, cultivating media that contained over 70% of medicinal herb extract remnants increased the growth rates and yields of Pleurotus ostreatus. In addition, these mushrooms had enhanced storage longevity due to their firmness. Therefore, medicinal herb extract remnants should be utilized in the cultivating media of various mushrooms.

The objective of this study was to evaluate the effects of different levels of red ginseng mare or Korean mistletoe powder on growth performance and physicochemical properties of thigh meat in broiler. A total of 200 broiler chicks were divided into five groups were fed a basal diet (control), basal diet supplemented with 0.5% red ginseng mare (T1), red ginseng mare 1% added (T2), Korean mistletoe 0.5% added (T3), Korean mistletoe 0.5% added (T4) for five weeks. Growth performance and proximate composition of chicken thigh meat were not influenced by all treatments, except for mortality and crude fat, which was significantly lower in all treatments with red ginseng mare or Korean mistletoe powder compared to control. Dietary red ginseng mare and Korean mistletoe supplementation had no significantly effects on pH, WHC, shear force, CIE $L^*$, $b^*$ values, triglyceride and glucose but TBARS values total cholesterol, and LDL-cholesterol were decreased (P<0.05) by the addition red ginseng mare and Korean mistletoe powder. CIE $a^*$ values increased significantly with added red ginseng mare and Korean mistletoe powder relative to the control (P<0.05). It was concluded that the addition of red ginseng mare and Korean mistletoe powder revealed minor improvements in the lipid oxidative stability of chicken meat.

This study was conducted to evaluate the chemical composition, digestibility, and energy value of 15 non-conventional feeds produced in South Korea as ruminant feeds. Three Hanwoo steers (body weight, $520{\pm}20.20kg$) fitted with a permanent rumen cannula and duodenal cannula were housed individually in tie-stall barns, followed by a 14-day adaptation period and 3-day experimental period. Chemical composition analysis, in situ nylon bag, and mobile bag technique were used as experiments. As a result of the chemical composition analysis offeeds, crude protein (CP) contentsofmalt meal, perilla meal, soy sauce cake, and soymilk residue were greater than 30%. As a result of the degradability characteristics analysis of feeds using an in situ nylon bag, rumen undegraded protein (RUP) contents of beet pulp, brewer's grain, coffee meal, malt meal, milo bran, perilla meal, ramen residue, and soymilk residue were greater than 50%. Analysis of total digestible nutrient (TDN) values of feeds using an in situ mobile bag showed that TDN values of beet pulp, brewer's grain, makgeolli residue, milo bran, perilla meal, ramen residue, rice bran, soy sauce cake, soybean curd cake, soymilk residue, and wheat bran weregreater than 50%. In summary, these non-conventional feeds have high potential value as good feed resources to replace formulated feeds or roughage. Therefore, the chemical composition, digestibility, and energy value of non-conventional feeds obtained from this study can be used as base data for the manufacture of ruminant total mixed ration (TMR) with improved feed efficiency, reduced feed costs, and reduction of environmental pollution.

Cucurbitaceous vegetable crops grown in greenhouses in Korea were surveyed from 1995 to 1997. Incidence of Sclerotinia rot was as high as $30{\sim}70%$ at its maximum on Cucumis melo var. reticulatus (netted melon), Cucumis sativus (cucumber), Cucurbita moschata (pumpkin) and Cucurbita pepo (summer squash) but relatively low on Citrullus lanatus (watermelon) and Cucumis melo var. makuwa (oriental melon). Symptoms of Sclerotinia rot developed on stems of all the cucurbits, fruits of five cucurbits except C. lanatus, petioles of two Cucurbita spp. and leaves of C. moschata. A total of 126 isolates of Sclerotinia sp. were obtained from the lesions and identified as Sclerotinia sclerotiorum based on the morphological and cultural characteristics. The fungus was very frequently isolated from stems and fruits of the cucurbits but rarely from petioles and leaves. Six isolates of the fungus were pathogenic to six cucurbits tested although there was some difference in virulence among the isolates to some of the hosts. C. lanatus was the most susceptible to the isolates, whereas C. melo var. makuwa was the most resistant. C. melo var. reticulatus and C. sativus were relatively susceptible to the isolates, and C. moschata and C. pepo relatively resistant.

For the effective use of soymilk residue (SR), by-product of soymilk production, barley Doenjang was manufactured. As the results, the contents of reducing sugar increase3 for 50 days in all samples and decreased thereafter. The contents of amino nitrogen increased prominently for 50 days, but increasing ratio was slightly slowdowned thereafter. The higher mixing ratio of SR, the less were the contents of reducing sugar and amino nitrogen. The contents of total acid also increased prominently for 30 days, but were slowdowned thereafter and the differences among all treatments were negligible. As the mixing ratio of SR was increased, the lightness and the yellowness increased and the redness decreased in 80days aged samples. In sensory evaluation of 90 days aged samples, the control was the best in soy sprout Doenjang soup. As the mixing ratio of SR increased, the taste was dropped slightly but no significant differences were obtained among sample A(barley koji 100, soybean 75, SR 25), B(barleykoji 100, soybean 50, SR 50) and C(barley koji 100, soybean 25, SR 75). In the original taste of Doenjang, the control was the best and as the mixing ratio of SR was increased, the point was dropped but these were no significant differences among control, A and B, and among A, B and C, and among B, C and D(barley koji 100, soybean 0, SR 100).

접목을 실시할 때 접수와 대목의 적정한 생육은 접목을 용이하게 할 뿐만 아니라 활착 후 접목묘의 묘소질 지속에도 커다란 영향을 미칠 수 있다. 자연광 조건에서 육묘를 실시하면 묘의 생육이 불균일하여 묘소질이 일정치 않게 된다. 그러므로 인공광을 이용한 폐쇄된 환경 조건에서 육묘가 바람직하나, 대목용 박에 대한 적정 광합성 유효광량자속 또는 광주기가 제시되지 않고 있다. 본 연구의 목적은 대목용 박의 초기 생육에 미치는 광합성 유효광량자속과 광주기의 영향을 구명하는 데 있다. (중략)
