  • This study was investigated about influence of different cold water irrigation on the nutrient uptake of leaf blade, rachis branches and chaff. Longer duration of cold water irrigation increased total nitrogen content in leaf blade, branches and chaff but decreased the content of phosphate, potassium and silicate. The highest content of total nitrogen and phosphate showed at heading stage, that of potassium in leafblades and branches at heading but in chaff at maturing stage, and that of silicate at maturing stage. Inorganic element content in branches was similar with that in chaff in general. The excessive uptake of nitrogen by cold water irrigation caused decrease in the uptake phosphate, potassium and silicate showing clear nutrient disorder in the blades and chaff. High total nitrogen and low silicate in rice plants seemed to lead to degeneration of branches and spikelets, and to spikelet sterility. Degeneration and sterility appeared to be closely related to nutrient status of branches.

  • To determine contents of inorganic elements of Laccaria, the carpophores of Laccaria laccata(Fr.) Berk. et Br., Laccaria amethystina(Fr.) Berk. et Br., Laccaria tortilis(S.P. Gray) Cooke and Laccaria vinaceoavellanea Hongo were incinerated and analyzed by atomic absorption spectrophotometer. Total contents of determined inorganic elements(except Cd) were highst in Laccaria tortilis than the other three mushrooms, and Laccaria vinaceoavellanea, Laccaria laccata and Laccaria amethystina in that order. The four species mushrooms contained potassium, iron, zinc, sodium, copper, manganese, and calsium in that order, and the content of potassium was the highst than the other inorganic components. The content of cadmium was Laccaria tortilis, Laccaria laccata, Laccaria vinaceoavellanea and Laccaria amethystina in that order.

  • This study was conducted to investigate contents of inorganic constituents, free sugars and catalpol in the Rhizoma of Rehmannia glutinosa as different growth stages. With the approach of harvesting season, the variations of their contents were as follow. The contents of P, K, Ca, Mg, Cu and ash in the Rhizoma decreased, whereas the contents of Fe, water and ethanol extract increased. The contents of total sugar, sucrose and galactose in the Rhizoma decreased, but the fructose and catalpol contents in the Rhizoma were increased.

  • The experiment was carried out to examine the effect of culture media and seawater on growth and mineral concentrations in Glasswort (Salicornia herbacea). Glassworts were grown in a greenhouse with 0, 10, 30 and 90% seawater and with or without nutrient media. The salinity tolerance affected on shoot height and Na, K and Ca concentrations significantly. The shoot height was increased with 10 and 30% seawater concentrations. At the higher seawater concentrations, more Na accumulated in a shoot was obserbed. The application of seawater concentration was effective on increasing Na, Mg, and Fe, concentrations and green leaf area rate and on decreasing K concentration. K/Na ratio of shoot was decreased at high seawater concentration, whereas Na concentrations was lowered at a low seawater concentrations. The mineral concentrations were changed according to the growing season. Na, K and Mg were high in June and Ca and P in September, respectively.

  • The proximate composition, minerals, fatty acids, and amino acids in three types of Ganoderma lucidum produced from timber bed cultivation, pot cultivation, and antlered form from pot cultivation were determined. The results obtained art as follows. The contents of crude fibers carbohydrates, crude proteins, crude fats and crude ashes were 47.2-499%, 29.1-31.1%, 15.2-15.6%, 4.0-4.4% and 1.3-1.7% on dry basis, respectively. The content of K (2,742-4,843 ppm in dry basis) was the highest, followed by p, Mg, Ca and Na. The ratio of unsaturated fatty acid in the total lipid was 81.0-82.1%. The major fatty acids were oleic acid and linoleic acid. The contents of histidine (9.47-13.06 mg/g on dry basis) and methionine (0.20-0.44mg/g in dry basis) were the highest and the lowest in the total amino acids, respectively.

  • General component and mineral contents according to species of Capsicum annuum were investigated. In addition, chuichung cucumber, white dadagi cucumber, and yellowish overripe cucumber were cooked by using seven different methods (boiling, steaming, pan-cooking, roasting, pan-frying, deep-frying, and microwaving), and retention rates of general components and minerals according to species were evaluated. Weight loss was observed in all cucumber species using all cooking methods. Most general component and mineral contents of C. annuum samples were significantly different according to species, and cooking method (P<0.05), whereas Fe and Cu contents were not significantly affected by species and cooking method, respectively. As a result, the highest protein, fat, ash contents were detected in deep-fried C. annuum, and high moisture contents were detected in raw, boiled, and steamed C. annuum. High mineral contents were detected in roasted and microwaved chuichung cucumber, deep-fried white dadagi cucumber and yellowish overripe cucumber. Retention rates of C. annuum by cooking method, ranged from 30~100% for protein, 10~100% for fat, 35~90% for moisture, and 30~100% for ash. High retention rates were observed for minerals in boiled, roasted, and microwaved chuichung cucumber, and deep-fried white dadagi cucumber and yellowish overripe cucumber. However, in yellowish overripe cucumber, mineral retentions rate were remarkably lowered by boiling and steaming, resulting in rates of 20~45%. These results were the data used as the basis for development of cucumbers.
