This study was conducted to elucidate the effect of after-ripening of gourd fruits before seed collection. Five varieties of commercial gourd varieties were cultivated and the fruits were picked after 24, 31, 50, and 70 days from pollination. For after-ripening treatments the fruits were placed for five days in a cool, air-circulated place while a number of fruits were placed for longer periods to 85 days including growing period, 24 + 62 days, 31 + 55 days, 50 + 35 days, and 70 + 15 days. The seeds collected from fruits harvested on 24^th day were not emerged at all, but the seeds from after-ripening treatment for 62 days showed 78% emergence or higher. The growth of seedlings showed the effects of after-ripening treatment of the fruits before seed collection; the seeds collected after ripening treatment showed better hypocotyl growth and larger embryo size than the non-treated seeds.

박 종자의 경우 CGMMV(Cucumber Green Mosaic Mottle Virus:오이녹반모자이크바이러스)에 감염되면 성체의 형태에서 농약으로 효과적인 방제가 불가능하다고 알려져 있다. 최근 국내외 종자회사에서 이병 된 종자를 판매하여 농가와 종자회사에 큰 타격을 입힌 것이 계기가 되어 바이러스 방제에 대한 효과적인 방제방법의 연구에 관심이 집중되고 있다. (중략)

This study examined similarity between white porcelain models and dress silhouette of women painted in genre painting in late Joseon period, and found that gourd bottles that are one of main porcelain styles are very similar with dress silhouette of women presented in genre painting in Joseon period; that is, bottle necks of gourd bottles and women's waist, voluminous bottles and erotically full hips, the length of skirts which showed underwear dress and height of porcelain's bottom, waist panel winding slim waist and wide edge of porcelain's mouth. As images are personal mental process of potters who were not socially controlled, they used dress as an indirect means of women's bodies for the subjects of images that are obtained through direct and indirect experiences of the persons who perceive. It indicates that they intended to make their ceramic works express women's dressing style through images of porcelain's models. Such images were sensual, but not superficial. It is suggested that they were influenced by the society which considered ethical experimental mind and practicality of the governing class of that time who enjoyed it metaphorically, but not impudent.

Koryo(918-1352) made a certain progress in her culture and agriculture except the latter part of the era when the development in social economy were retarded due to military dictatorship and Mongol invasion. Despite of these external conditions, cultivations and kinds of horticulture foods were expanded With the help Of many king's agriculture first policy and the advancement in cultivating method . Among the horticulture foods, fruits such as peach, plum, Japanese apricot, apricot, cherry, pear, persimmon, pomegranate, crab apple, Jujube, grape, Chinese quince, walnut, orange, yuzu, chestnut, ginkgo nut(silvernut), pine nut, nutmeg nut, and fiat were crowed, and vegetables such as Chinese cabbage, turnip, radish, garlic, welsh onion, gynmigit, scallion, taro, malva, cucumber, white gourd, bottle gourd, water melon, eggplant, Japanese ginger, ginger and litchi were cultivated, while semi, water shieled and bamboo sprouts were taken in natural. Fruits were taken in natural or through dry, and particularly grapes were used to make wine, Flowers of Japanese apricots, some fruit trees, and chrysanthemum were also made into wine. Certain fruits were used as medicine owing to its medicinal nature. Vegetables were used to make Kimchi or to boil soup, sometimes they were dried to be kept in storage to be used in rare season and also used as medicine Increase in kinds of horticulture foods does not have any direct relation with the reform of social economy, but the fact that so many kinds of horticulture foods were cultivated and used in Koryo era shows that they elevated people's life and dietary culture.

This study was designed to examine the effects of fractions of ethanol extract of Benincasa hispida (wax gourd) on hepatic antioxidative status in streptozotocin (STZ) induced diabetic rats. Sprague-Dawley rats were induced diabetes mellitus by STZ injection (45 mg/kg) into the tail vein and were divided into 5 groups: normal, STZ-control, three experimental diabetic groups. Fractions of ethanol extract of Benincasa hispida were administered orally into the diabetic rats for 14 days. Hepatic glutathione peroxidase (GSH-px) activity (determined with H$_2$O$_2$ as substrate) was increased in the groups supplemented with chloroform (CHCl$_3$) and butanol (BuOH) fractions. Glutathione peroxidase (GR) activity in the liver cytosol of H$_2$O fraction groups was significantly lower than that of STZ-control group. The H$_{2}$O fraction supplemented group has been shown the notably decrease in the hepatic superoxide dismutase (SOD) activity. The hepatic cytosol catalase (CAT) activity was significant decreased by the supplementation with BuOH fraction. It was found from the results that the supplementation of BuOH and H$_2$O fractions of Benincasa hispida extract could be beneficial for the diabetic complications and damages from the lipid peroxidation.

This article examines the conservation process of a donated Gourd-style jar (Object No. Geumja No.124), which was broken into several fragments (more than 60) in the past. After assessing the condition of the object, each of the fragments were re-attached, and missing areas were gap-filled and re-touched. The authors discuss considerations, which were taken into account during the decision making process. These include the integrity of the object and the section of treatment materials, such as the reversibility of adhesives and filling materials. After its conservation, the authors believe that the object is in a better condition and ready for display in the future.

Bottle gourd (Lagenaria siceraria Standl.) has been used as a rootstock for the watermelon cultivation because of better growth ability at low temperature and avoidance from contamination of the soil disease. Since the genetic source for the elite rootstock is limited in nature, the genetic engineering method is inevitable to develop new lines especially to obtain the functionally important or multi-disease resistant bottle gourd. Recently, our lab has set up a successful system to transform the bottle gourd. in order to monitor the transformation process, GFP gene is used. Cotyledons of the inbred line 9005, 9006 and G5 were used to induce the shoot under the selection media with MS + 30 g/L sucrose + 3.0 mg/L BAP + 100 mg/L kanamycin + 500 mg/L cefotaxime + 0.5 mg/L $AgNO_3$, pH 5.8. The shoot was developed from the cut side of the explants after 3 weeks on the selection media. The shoot was incubated in the rooting media with 1/2 MS + 30 g/L sucrose + 0.1 mg/L IAA + 50 mg/L kanamycin + 500 mg/L cefotaxime, pH 5.8 and moved to pot for acclimation. Although the shoot development rate was depended on the genotype, the G5 was the best line to be transformed. Monitoring GFP expression from the young shoot under microscope could make the selection much easier to distinguish the transformed shoot from the non-transformed shoots.
