Sugars and organic acids in Korean hot pepper fruit (C, annuum L.) according to its portions, pericarp, seeds and placenta, were determined by gas liquid chromatography (GLC). ${\alpha}-\;and\;{\beta}-fructoses,\;{\alpha}-\;and\;{\beta}-glucoses$, galactose, sucrose and maltose were identified. Major sugar in pericarp was fructose, while those in seeds and placenta were surose and fructose. Amount of free sugars in seeds was higher than that in pericarp or placenta. Succinic, fumaric, malic, tartaric, citric and quinic acids were found. Citric acid was a major organic acid found in pericarp and placenta. The amount of each identified organic acid, however, was similar in seeds. Quantity of total organic acids identified in pericarp or placenta was higher than that in seeds.

The biological activities of water extracts from different fruit parts, such as peel, flesh, and placenta, of oriental melon were investigated. The concentrations of total phenolic in fruit extracts were $816.37\;{\mu}g/ml$, $385.23\;{\mu}g/ml$, and $925.56\;{\mu}g/ml$, respectively. Whereas the total flavonoid content in the peel extracts was $231.21\;{\mu}g/ml$, those in the extract of flesh and placenta were $8.16\;{\mu}g/ml$ and $36.07\;{\mu}g/ml$, respectively. The DPPH free radical scavenging activity of each fruit extract at 10,000 ppm was 34.84% for peel, 10.70% for placenta and 9.26% flesh. The ABTS radical cation decolorizing activity of each fruit extract at 10,000 ppm was in fruit extracts were 72.92% for peel, 48.0% for flesh and 74.31% for placenta. In addition, xanthine oxidase inhibitory activity, ${\alpha}-Glucosidase$ inhibition activity, and tyrosinase inhibition activity of the peel extracts appeared to be higher than those of placenta and flesh. Taken together, these results indicated that the peel part of oriental melon contained higher level of total flavonoid content, and several physiological activities including antioxidation, ${\alpha}-Glucosidase$ inhibition activity, and tyrosinase inhibition activity than did the flesh and placenta parts, and suggested that the peel might have a potential to be applicable as a source for functional foods.

The capsaicinoid content of F$_{1}$ hybrids between annuum L. 'California Wonder', four native Japanese cultivars, and three Korean F$_{1}$ cultivars were evaluated and the results compared with parental cultivars. The capsaicinoid content was higher in the placenta than in fruit flesh. The placenta of 'Yatsufusa', 'Taka no Tsume', 'Cheongyang', 'Sinhong', and Geoseong' were the most pungent cultivatrs, with capsaicinoid content of more than 1000mg/100g DW, while 'California Wonder', and 'Fushimi Amanaga' contained trace amounts. Capsaicinoid content in F$_{1}$ hybrids varied with reciprocal crossing. Capsaicinoid content also varied with fruit development, rapidly increasing in the fourth or fifth week after flowering, and thereafter slowly declined.

The biological activities of water and ethanol extracts from different fruit parts, such as peel, flesh, and placenta of oriental melon were investigated. The total phenolic concentration of water extract was the highest such as 151.64 ${\mu}g/g$ in the peel, also that of ethanol extract was 224.77 ${\mu}g/g$ in the peel, respectively. The total flavonoid content in the water and ethanol extracts were high such as 45.53 ${\mu}g/g$ and 67.16 ${\mu}g/g$ of peel, respectively. In the physiological activities, DPPH in the water and ethanol extracts were high such as 25.0% and 83.3% of peel in 1% concentration. Extract of peel was higher than those of flesh and placenta. ABTS in the water extracts was 79.2% of peel, 57.6% of flesh and 74.0% of placenta in 1% concentration. Ethanol extracts was 99.9% of peel, 52.1% of flesh and 41.2% of placenta in 1% concentration. In addition, xanthine oxidase inhibitory activity and ${\alpha}$-Glucosidase inhibition activity of the peel of water and ethanol extracts appeared to be higher than those of placenta and flesh. This study showed that the antioxidant and ${\alpha}$-Glucosidase inhibition activity of peel extracts were higher than those of placenta and flesh. Also, the antimicrobial effect of ethanol extract from different fruit parts was shown only on Streptococcus agalactiae.

The experiment was conducted to investigate the relationship between $Ca^{2＋}$ uptake and development of fermented fruit through the forced-air circulation of ambient fruit. Air circulation of ambient fruits were adjusted with 0.3m/sec wind velocity for three hours a day from 10：00 to 13：00. Treatments consisted of 0, 10 day, 20 day, 30 day of forced air circulation of ambient fruit. Although the results varied depend on the duration forced air circulation, in general, treated fruit increased fruit weight, flesh thickness, fruit hardness, soluble solids, and chromaticity, and decreased the number of fermented-fruit. $Ca^{2＋}$ content in fruit.

We investigated the structure of floral organs and possibility of seed-set to breed a variety in ginger Zingiber officinale Rosc. Floral bud was formed from collected domestic Seosan var, and foregin Thailand var, the number of florets per bud were 8 and 10 in Seosan and Thailand var, respectively, Flowering time ranged from 18 to 25 August irregularly at 4-5 pm. The flower has the long styled with fiber hairs on top of stigma and connected-two anthers. Pollens were mixed of circular and ellips shape and its extine was two layer structure. Callus formation from anther explants was effective with compact and embryogenic on N$_{6}$ medium supplemented 2 mg/l of NAA(NCM). Plant regeneration was on the MS medium with BA of 1-2 mg/l from 40 days old callus after transferred callus medium.m.

Variations of hot-taste constituents during the age of after-ripening in different anatomical parts and capsaicin series components of hot-pepper fruits were studied 1. Capsaicin homologues were composed nearly same portion during the after-ripening. 2. Percent amounts of hot-taste constituents per dried pepper fruit (except seeds) increased constantly during the after-ripening. And this suggests the production of hot-taste constituents and changeable mutual relations between various constituents. 3. Notable amounts of hot-taste constituents were contained in placentae and dissepiment and increased in succession until the climacteric onset stage, but after this period decreased. On the contrary, a constant increasing tendency were shown in pericarp. These results are presumable to understanding the role of the pepper fruits in regulating constituents transport from one part to another. 4. In the seeds, there was not marked amounts of hot-taste constituents, but increased quite slightly during the after-ripening.

This study was conducted to assess effects of soil moisture condition and ventilation on development of fermented fruit of oriental melon. In higher soil moisture condition (-10 kPa), roots absorbed more water and transpiration was decreased under low temperature and high humidity conditions. Development of fermented fruit may be come from absorbed water concentrated placenta with higher soluble solid. Fermented fruit was developed with higher level at Shintozoa and Elite, was developed with lower level at Hongtozoa, and was not developed at self-rooting of oriental melon. Ventilation on fruit did not affect development of fermented fruit at Shintozoa, Elite, Hongtozoa and self-rooting seedling. Ca contents of flesh and placenta of fruit under ventilation treatment were higher than control but contents of Acetaldehyde, Ethanol and Ethylacetate were lower.

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.
