  • BACKGROUND: Crop rotation is often used as a solution to eradicate nematodes in soils used in plastic film houses for long-term cultivation of oriental melon. However, it is not clear if the double-cropping is effective in reducing nematode populations in soils. METHODS AND RESULTS: Nematode population in plastic film house soil was measured during oriental melon cultivation from April to July in short term crop rotation systems of oriental melon. Double-cropping of chinese cabbage in open-field for 3-4 months following oriental melon in plastic film houses could not prevent the build-up of high population density of nematodes. However, double-cropping of dropwort in flooded soil for 3-4 months following oriental melon in plastic film houses could effectively reduce the nematode population during the successive year of oriental melon cultivation. The reduced nematode population in soils of oriental melon-dropwort double-cropping system was continued until the mid season of progressive year oriental melon cultivation. Application of nematicide to soil before growing oriental melon in the oriental melon-dropwort double-cropping was very effective in preventing the build-up of high population density of nematode in plastic film house soils. CONCLUSION: Short-term introduction of crop rotation was not effective in suppression of high population density of nematodes in plastic film house soils of long-term year-to-year production of oriental melon. For securing the soil productivity and sustainability of plastic film house, various physical, chemical, and agronomic practices should be properly combined together.

  • This study aims to examine the potential reasons for the current prevalence of the fusarium wilt in the oriental melon. Twenty-seven Fusarium isolates obtained from oriental melon greenhouses in 2010-2011 were identified morphologically and by analysis of elongation factor-1 alpha gene (EF-$1{\alpha}$) and internal transcribed spacer (ITS) rDNA sequences as 6 Fusarium species (8 isolates of F. oxysporum, 8 F. commune, 5 F. proliferatum, 3 F. equiseti, 2 F. delphinoides, and 1 F. andiyazi), which were classified as same into 6 EF-$1{\alpha}$ sequence-based phylogenetic clades. Pathogenicity of the Fusarium isolates on the oriental melon was highest in F. proliferatum, next in F. oxysporum and F. andiyazi, and lowest in the other Fusarium species tested, suggesting F. proliferatum and F. oxysporum were major pathogens of the oriental melon, inducing stem rots and vascular wilts, respectively. Oriental melon and watermelon were more susceptible to F. oxysporum than shintosa and cucumber; and cucumber was most, oriental melon and watermelon, medially, and shintosa was least susceptible to F. proliferatum, whose virulence varied among and within their phylogenetic subclades. Severe root-knot galls were formed on all the crops infected with Meloidogyne incognita; however, little indication of vascular wilts or stem and/or root rots was shown by the nematode infection. These results suggest the current fungal disease in the oriental melon may be rarely due to virulence changes of the fusarium wilt pathogen and the direct cause of the severe root-knot nematode infection, but may be potentially from other Fusarium pathogen infection that produces seemingly wilting caused by severe stem rotting.

  • The objective of this study was to use 'Danta PR', NGS (Next Generation Sequencing) technology for genome resequencing to develop polymorphic makers between Chinese oriental melon, 'Hyangseo 1' and Korean oriental melon. From the resequencing data that covered about 81 times of the genome size, 104,357 of SSR motifs and Indel, and 1,092,436 of SNPs were identified. 299 SSR and 307 Indel markers were chosen to cover each chromosome with 25 markers. These markers were subsequently used to identify genotypes of 'Danta PR' BC1 (F1 x 'Danta PR') population and a genetic linkage map was constructed. SSR, Indel, and SNPs identified in this study would be useful as a breeding tool to develop new oriental melon varieties.

  • The aim of this work is to evaluate the potential of oriental melon (Cucumis melo L. var. makuwa Makino) seeds for the management of type 2 diabetes by controlling glucose absorption. The ${\alpha}$-glucosidase and ${\alpha}$-amylase inhibitory effects of the hexane extracts from oriental melon seeds were investigated. A bioassay-guided fractionation technique was used to elucidate the principal active components. The results show that the hexane extract from oriental melon seeds exhibited high inhibitory activities against ${\alpha}$-glucosidase and ${\alpha}$-amylase. The hexane extract was further fractionated into four sub-fractions. Among them, the sub-fraction F-1 exhibited the most potent anti-diabetic effect. The active components were isolated and identified by gas chromatography/mass spectroscopy (GC-MS). Free fatty acids showed significant hypoglycemic activity (p < 0.001) and fatty acid composition influenced enzyme inhibitory activities. These results suggest that oriental melon seeds could be used to prevent type 2 diabetes.

  • 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.

  • Although the requirement and optimum soil level of Si for oriental melon are still not well understood, silicate fertilizer is commonly applied to the oriental melon in plastic film houses where soil silicate level is relatively high. In this research the effects of silicate fertilizer on growth, fruit yield and fruit quality of oriental melon, and soil properties were investigated in plastic film house where the soil available silicate was $212mg\;SiO_2\;kg^{-1}$. Silicate fertilizer was applied in the rates of 100, 200, and $300kg\;10a^{-1}$. The application of silicate fertilizer could not increase the early growth of oriental melon, and also the fruit yield and quality were not different among the treatments. Available Si and P contents in soils and also Si and P contents in leaf of oriental melon of the different treatments were not significantly different. In the relationship between total Si in oriental melon leaf and soil silicate extracted by 1 N sodium acetate, optimum soil available silicate level for oriental melon was found to be around $100mg\;SiO_2\;kg^{-1}$. These results indicate that the additional silicate fertilization in soils of available silicate higher than $100mg\;SiO_2\;kg^{-1}$ is unnecessary, and such application of silicate can not have any beneficial effect on the growth and fruit yield of oriental melon.

  • BACKGROUND: During the off-season, the cultivation of Chinese cabbage and water dropwort is often used to desalinize plastic film house soils. The objective of this study was to verify the effect of double-cropping systems on the salt removal in oriental melon cultivated plastic film house soils.METHODS AND RESULTS: Electrical conductivity (EC) and soluble salt contents were measured in soils collected from plastic film houses of oriental melon cultivation before and after the off-season crop cultivation. Also the same measurements were performed in the next oriental melon season to estimate the desalinization effect of double-cropping systems. During the cultivation of Chinese cabbage under open-field condition, ECeof surface soil was reduced from 6.0 to 0.8 dS/m. Double-cropping of water dropwort in flooded soil was also efficient in removing the salts accumulated during oriental melon cultivation. In the house soils where salts were removed during the off-season crop cultivation, soil ECewas maintained below 3 dS/m during the next oriental melon cultivation season.CONCLUSION: The off-season cropping under open-field or flooded condition was effective in desalinization of plastic film house soils. Since the salt removal effect is not expected to last for several years, the double-cropping system should be introduced every season to maintain soil EC below the critical level.

  • The objective of this study was to investigate the anticancer effects of the extracts of oriental melon seeds. Various solvent extracts of oriental melon seeds were prepared and their anticancer effects were examined using in vitro MTT and CV assays. The anticancer effects of various extracts of oriental melon seeds were also examined in five human cancer cell lines including A549, AGS, HT-29, MCF-7 and HepG2. The ethanol extract of heated oriental melon seeds showed the potent cytotoxic effects especially against mouse hepatoma cell line(Hepa1c1c7), human hepatoma cell line(HepG2) and human breast cancer cell line(MCF-7). These data suggest that oriental melon seeds can be a promising anticancer agent against human liver and breast cancer.
