  • This study was conducted to investigate the physicochemical quality properties of oriental melon pickles harvested after pollination (green and fully ripe period) and soaking (cured and ripened). After the increase of the pollination size of melon, at 21 days, melon had a strong yellowish color, but at 24 days, its tip was completely yellow. In addition, 21 days after 5 days soaking, the weights of the harvested melons were reduced. Since then, there were no remarkable changes in weight. At 27 and 30 days, the b values of the melons that were harvested showed no trace of influence by the number of days of soaking and ripening. The melons harvested after 24 and 27 days, and the oriental melon pickles, maintained a constant hardness and texture after five days of soaking. This result indicates that melons harvested between 15 and 27 days after pollination can be used for melon pickles. To produce high-quality melon pickles with a yellowish color and a chewy texture, melons harvested 27 days after pollination and then soaked and ripened in salt water for 15 days should be used.

  • Oriental melon has been increased in production amount, but its processed food was not made in spite of the fact that shelf-life of the fresh fruit is short. This study was carried out to develop a dried product with no use sulfur treatment. Fresh melons were peeled, cut into 6 pieces, and soaked to the following pretreatments soaking in sugar syrup(SS), sodium chloride(SC), ascorbic acid(AA) and sodium polyphosphate(SP). After preatreatments the melon pieces were dried by hot air drying at 5$0^{\circ}C$ for 9 and 12 hours, and the dried melons were air blown at $25^{\circ}C$ for 1 day. The dried samples were evaluated for moisture content, texture, rotor, and sensory quality. The moisture content of dried melons soaked in SS and SC were lower than those that were soaked in AA and SP after hot air drying. The melons dried for 12 hours were high in hardness, gumminess, chewness and adhesiveness and excellent in sensory evaluation compared to 9 hours. The "L" value of SS was higher and the "a" value was lower in Hunter color. And SS treatment inhibited browning of the dried melon and improved sensory characteristics in color, flavor, texture and taste. Sucrose concentration had no significant effect on color, hardness and sensory score in banal product. The combination of SS with SP represented a highly effective antibrowning treatment for the dried melon and the product was kept in good color for 3 months at room temperature.at room temperature.

  • Contents of mineral element and cytokinin in the xylem sap of 'Keumdongee' and 'Tongilhwang' oriental melons were compared with those in oriental melons grafted onto 8 rootstocks. The effect of grafting on the fruit quality of oriental melon was also investigated. Flesh firmness varied with rootstocks. Soluble solids contents in the placenta tissue of grafted 'Tongilhwang' were higher than that in the 'Keumdongee'. Electric conductivity of the xylem sap in own-rooted plants was higher in 'Keumdongee' than in 'Tongilhwang', but it increased in 'Tongilhwang' once they were grafted. The sap volume per plant was greater in 'Keumdongee' than in 'Tongilhwang'. The mineral concentrations varied considerably depending on the rootstock used. Xylem sap of grafted oriental melons contained a higher amount of mineral ions, especially $NO_3{^-}$ and $PO_4{^-}$, than did the sap in own-rooted plants. The increase in the mineral levels in sap due to grafting was most apparent in 'Tongilhwang'. Xylem sap from both 'Keumdongee' and 'Tongilhwang' contained trans-zeatin (t-Z), trans-zeatin riboside (t-ZR), and dihydrozeatin riboside (DHZR). Small amounts of isopentenyl adenine (IPA) and isopentenyl adenine riboside (IPAR) were also detected. Trans-zeatin riboside was the most abundant, followed by t-Z. Cytokinin concentration in 'Keumdongee' was not significantly influenced by rootstock type used, although the highest concentration of cytokinins in 'Keumdongee' was obtained with 'Chamtozwa' rootstock. However, the cytokinin concentration in 'Tongilhwang' increased with grafting irrespective of rootstock type used.

  • Effect of anoxia treatment on alcohol fermentation in the placenta of oriental melons (Cucumis melo) at different developmental stages was studied. Results showed that fruits at the rapid growth stage (stage III) contained the lowest amount of acetaldehyde and ethanol as compared with fruits at other developmental stages. During anoxia treatment, a steady increase in ethanol content was observed in the placenta of oriental melons, regardless of their developmental stages, while the increment of acetaldehyde content was relatively small. Alcohol dehydrogenase in growing and maturing stage fruits showed increased activity with the maximum value at one day after the onset of anoxia treatment and then decreased gradually. An increase in the activity of pyruvate decarboxylase was also observed during anoxia.

  • Oriental melon vinegar was prepared by two stage fermentations of alcohol and acetic acid. In the alcohol fermentation using oriental melon residual products, alcohol content showed 7.43% in 17$^{\circ}$ brix of initial sugar concentration and 80 h of fermentation time. In the acetic acid fermentation using oriental melon alcohol, acidity showed 5.25% in 250rpm of agitation rate and 200 h of fermentation time. The cultivation esults of oriental melons using its vinegar are as follows. Quantity and quality of samples treated with 500, 1,000 and 2,000 times of oriental melon vinegar were higher than that of control : weight, quality, sugar content and goods production rate were higher to degree of 33∼42 g/piece, 370 ∼460kg/10a, 0.6∼.9$^{\circ}$ Brix, 2∼5%, respectively. Coods production yield of samples treated with 500, 1,000 and 2,000 times of oriental melon vinegar was higher (400∼610 kg/10a) than that of control. The results of control of powdery mildew on oriental melons using oriental melon vinegar as the diluted solution with 500 and 1000 times were identical for control value that used by agrochemical. Powdery mildew were exterminated by 2nd treatment of the diluted solution. In case of aphids, the diluted solution with 500, 1,000 and 2,000 times of oriental melon vinegar exterminated thoroughly by 2nd treatment.

  • The investigation and the analysis of soil chemical properties, microbial flora and cultural practices in plastic house of 60 farms (pepper 20, cucumber 20, oriental melon 20) were conducted in Chonnam area film. An amount of fertilizer application of farms was more than that of standard fertilizer application. That was phosphate at two and a half times, potassium at twice and manure at three times the amount of standard application. It was inferred that excessive fertilizer application would lead to salts accumulation in soil. Continuous cropping injury would be incurred by excesive salts accumulation in soil. Even if inorganic elements in soil culturing peppers, cucumbers and oriental melons were greater than optimum level, base-saturation degree of soil culturing peppers, cucumbers and oriental melons was 40:18:12, 55:16:14 and 40:27:11 respectively. That was lower than the optimum levels (60:15:5). Therefore, crops would be affected by uptake inhibition by nutrition imbalance. Density of Fusarium is related to plant decease in soil i.e. pepper $26.2{\times}10^2\;cfu\;g^{-1}$, cucumber $75.8{\times}10^2\;cfu\;g^{-1}$ and oriental melon $6.5{\times}10^2\;cfu\;g^{-1}$. B/F of soil planted with pepper, cucumber and oriental melon was 91.2, 80.4 and 18.8, respectively.

  • The main purpose of this study is to provide the back-from-city farmers with the information about the melon cultivation technology by surveying 268 farm houses in the major melon producing districts such as Seongju and Chilgok. For the purpose, this study classifies the essential technologies that the melon experts think as most important into 6 categories: size of plastic film house, covering film, varieties of oriental melon, lagging cover, ventilation method and ways to reduce repeated-cultivation damage. The result of the study shows that the back-from-city farmers should consider the following items when they choose to cultivate oriental melons. For the size of plastic film house, the ventilation method and the covering film of plastic film house, it is better to choose the latest technology. Even though it may require larger initial investment, the latest technology can increase the production and lower the cost. In case of variety, it is better to choose popular or the most widely grown ones rather than the new ones. The lagging cover should be selected in consideration of climate conditions such as average temperature and humidity, transplant time and harvest time of the farming region.

  • The protected horticulture sector was evaluated as achieving the highest level of agricultural industrialization, this study examined the structural changes in the field of Korea oriental melon farming, where cultivation under structure has advanced through its long history, with the focus on intensification and concentration of agriculture. From the 1970's, the oriental melon farming labor were replaced by capital due to the increase of dependence on input industries and the decrease in labor input, thus intensification improved the productivity. Through the development, Seongju-gun of Gyeongsangbuk-do, experienced faster growth of cultivation compared to other regions, and gained a competitive edge in productivity which led to the spatial concentration as well as the concentration of farms. In this restructuring process of oriental melon farming, spatial inequality intensified throughout the agricultural development as the existing farming spaces underwent a dynamic shift.
