This study compares and analyzes inorganic components of four different Pu-erh tea species consumed in Korea. The criteria for the inorganic components was based on the Royal Institute of Technology (KTH) recommendations. Out of the 19 general items: potassium, manganese, silicon and fluorine were detected in amounts exceeding the maximum allowable concentration by 5~23, 57~91, 1.6~1.8 and 9~18 times respectively. Out of the 15 potentially harmful elements: aluminum and nickel were exceeded the Maximum allowable concentration by 9~14 times and 0.8~1.2 times respectively. To reduce the concentration of inorganic elements in excess of the maximum allowable concentration, the extraction time of tea should be less than 1 minute in addition to limiting the amount. The amount of Pu-erh tea for extraction was about 0.1 g manganese, about 0.3 g potassium, about 0.5 g fluoride and about 2 g silicon. Therefore, the maximum amount of tea for extraction should be 0.1 g in regards to the safety of Pu-erh tea. Based on the recommended maximum daily intake of inorganic ingredients by the Ministry of Food and Drug Safety, it is desirable that the number of extractions be less than three.

Plant nutrition one of the most important factors that increase plant production. Thus, the present study was carried out to investigate the effects of NPK (three main macro elements of fertilizer) and their interactions on morphological and biochemical contents of Deodeok (Codonopsis lanceolata). Results exhibited that application of different fertilization treatments had a considerable effect on the different vegetative growth characteristics of C. lanceolata compared to the non fertilizer control. Plant height showed significant results towards all fertilization group compared to non fertilizer group, and the highest value (266.8 cm) for plant height was observed from the N+P+K group. The growth of internode was converted to vine after node 5, no fertilizer effects were found on internode elongation. Chlorophyll content showed a high amount in the range of 42.8 to 46.6 against all fertilization treatment groups, except P+K group. The highest values (57.0 g) for the fresh weight of roots were obtained from the N+P+K groups compared to non fertilizer group. The mineral nutrient content of Na, Mg, Cu and Al of the roots of C. lanceolata showed the lowest amount from in P+K groups compared to other groups. In addition, P from N+K group, Mn from N+P group and Ca, Fe, Zn from N+P+K group also exhibited the lowest mineral content compared to other groups respectively.

Background : This study was conducted to investigate the effect of soluble silicate and germanium on the characteristics of soil and growth in ginseng (Panax ginseng C. A. Meyer) cultivated in blue-white plastic houses. Methods and Results : Seedlings (n = 63 per 3.3 ㎡) of Korean ginseng cultivar were planted on April 10, 2015. Shading material of plastic house [8 m (W) × 3.5 m (H) × 50 m (L)] was blue-white vinyl. From May to September of each year, 1,000 times diluted sol. of germanium and silicate and these mixed solutions were drenched once a month. The chemical properties of the soil are as follows : pH, EC, organic content, and P2O5 of the soil were within the proper range, and the Mg content of the Ex-cations was lower than the standard value in 3 treatments except treatment of germanium 1,000 times. The total nitrogen content was 0.13 - 0.14%, which was higher than the optimum value. The number of soil microorganisms (Actinomycetes etc.) was higher in the treatment than in the non-treatment of inorganic components. The photosynthetic rate of ginseng leaves was 2.25 μmole CO2/㎡/s in the non-treatment and 2.91 to 3.17 μmole CO2/㎡/s in the inorganic treated. The growth characteristics of the aerial parts (leaf and stem) of the ginseng plants were generally better than that of non-treatment. Especially, in the treatment with silicate 1,000 times showed better growth, leaf area and leaf width growth. The growth of the underground part (root weight etc.) were also better than non-treatment. Specially, at 1,000 ppm treatment with soluble silicate, the root length and diameter were longer and the weight was was 72.2 g per plant. The ginsenoside content of each treatment is under analysis. The disease incidence (Alternaria panax etc.) rate was 20.1% in the untreated and 6.4% to 10.0% in the inorganic components treatment. Conclusion : By soil drench of inorganic compononts such as soluble silicate in ginseng blue-white plastic house cultivation, the growth of the aerial and root parts in ginseng were more improved than non-treatment. There are a lot of soil microorganism and less disease.

Background : This study was conducted to investigate the effect of inorganic compounds (germanium etc) on the characteristics of growth and ginsenoside contents in Korean ginseng (Panax ginseng C. A. Meyer) cultivated in plastic houses. Methods and Results : The experiments were performed in the Jinan (elevation: 300 meters above sea level). Seedlings (n = 72 per 3.3㎡) of Korean ginseng cultivar were planted on March 23, 2015. Shading material of plastic house was blue-white vinyl. From May to September of each year, 500 and 1,000 times diluted solution of germanium and silicate and these mixed solutions were drenched once a month. The chemical properties of the soil are as follows : pH, EC, organic content, and P2O5 of the soil were within the proper range, and the Mg content of the Ex-cations was lower than the standard value in 3 treatments, including 500 times solution of silicate. The rate of photosynthesis in Korean ginseng leaves were 2.2 - 2.5 μmole CO2/㎡/s in germanium and silicate treatment than in the non-treatment (1.5 μmole CO2/㎡/s). In the mixed treatment of silicate and germanium, the growth characteristics of the aerial parts (leaf and stem) of the Korean ginseng plants tended to be higher and longer than the other treatments. In a mixed germanium and silicate treatment, the root length was 33.3 ㎝, diameter was 23.5 ㎜, and the weight was the best at 53.8 g. The ginsenoside content was 16.8 ㎎/g in germanium treatment, 16.3 ㎎/g in germanium + silicate treatment. These were 37% and 33% higher than the control, respectively. The incidence of disease such as Alternaria panax was less in the inorganic treatment than in the non-treatment, and the incidence of disease was significantly decreased in the treatment with germanium + silicate. Conclusion : By soil drench of inorganic ingredients in Korean ginseng plastic house cultivation, the growth of the aerial and root parts in ginseng were more improved than non-treatment and ginsenoside content was increased and decreased the incidence of disease.

This study was performed to investigate the growth characteristics and inorganic components of Codonopsis lanceolata regarding regional differences. The plant height of Japanese Codonopsis lanceolata was 373.6 cm, so it’s revealed that it has more vigorous growth than Korean won. The flowering time of Korean Codonopsis lanceolata was 2 weeks faster than Japanese one. Total fresh weight of root was 41.0 g and 39.0 g for Korean and Japanese respectively, thus, no significance difference was found. However, regarding fresh weight, Korean one had a more fresh weight (35.4 g) of main root parts, but Japanese one had a more fresh weight (9.6 g) of the lateral root part. Each inorganic component was found more in the aboveground parts, regardless of the region and the content of K was the largest. Regarding the content of macroelements for each part of Codonopsis lanceolata, the content of Na, Mg, P, S, and Ca in Korean Codonopsis lanceolata was found the highest on the leaf, followed by stem and root. In the case of Japanese Codonopsis lanceolata, same result was found on the content of Mg and Ca, however, the highest content of Na and P was found in the stem.
