This experiment was carried out in order to study the changes of morphological characters of the growth and thatch accumulation in :3 varieties of Kentucky bluegrass under removing clipping residues as affected by cutting management. The varieties used were Park, Kenhiuc and Newport.The results obtained are as follows; 1. The dry weight of leaf. stem and number of tiller was highest at 22. June and lowest at 21. Aug in alt varieties. And then the dry weight of rhizome, root and thatch increased with growth progressed) Tabte 3). 2. The relationship of the dry weight of biological yield and number of tillers was quadratic ally increased in the growth stage of spring($R^2$= 0.982**), and linearlly increased in the growth stage of autumn(r 0.944*)(Fig. 1). :3. The dry weight of thatch increased as an exponentially equation in alt :3 varieties of Kentucky blue-grass(Fig. 2). Thatch increased rate(TIR) can used to estimate the specifying a quantity of thatch accumulation from the turf. Thatch increase rate equation as follows. where TH$_2$ is the dry weightof thatch at T$_2$ survey time and TH$_1$ is the dry weight of thatch at $TH_1$ is the dry weight of thatch at $T_1$ survey time. $TIR(mg/cm^2/day)=\frac{Ln\;TH_2 - Ln\; TH_1}{T_2 - T_1}$ 4. Correlation coefficients between the dry weight of thatch and leaf weight was -0.633(P>0.05), and number of tiller of tillers was -0.666(P>0.5), respectively. It means that thatch accumu-lation increased with growth depression of leaf and stem.

The purpose of this study was to investigate the effect of water extract of Dioscoreae Rhizome on the reproduction activity of Wistar male rat. The group treated with 1.0 g/kg/day oral administrations of water extract of Dioscoreae Rhizoma (SK0l6) during 8 weeks was compared with the normal group. Sperm count, sperm motility, body weight, and testis weight were investigated in two groups. Sperm count. body weight, and testis weight of two groups did not show the significant difference. But sperm motility of the treated group was reduced significantly (the normal group: 56.43 %, SK0l6 group: 53.47 %, p < 0.05). According to the results, SK0l6 have no effects on sperm count, body weight. and testis weight but reduced sperm motility significantly.

The objective of this study was to improve the recycling rate of coal ash fly, industrial waste. This study was conducted to analyze the physico-chemical properties of \"CellCaSi\" and clarify the effects on the growth of Kentucky bluegrass(Poa pratensis L.) and creeping bentgrass(Agrostis paulstris Huds \"Penncross\") and the chemical properties of soil, which was cellular calcium silicate reproduced by coal ash fly. A field assay was carried out in Young-Pyong Golf Course. The results were as follows. 1. The main chemical composition of CellCaSi was $SiO_2$(45~55%) and CaO(25~35), which was 70~90% of total weight. CellCaSi showed pH 8~9. Bulk density of CellCaSi was 0.35~0.45g/㎤. Water content of CellCaSi was 52.5~67.5%. 2. In the applied plots, leaf width, grass density per $1\textrm{cm}^2$, rhizome number and length per plant, and root number per plant of Kentucky bluegrass(Poa pratensis L.) and creeping bentgrass(Agrostis paulstris Huds \"Penncross\") showed increasing tendency compared with the control. The application of CellCaSi increased the growth of turfgrasses. Their visual quality on hardness, grass shoot density per $1\textrm{cm}^2$ and root growth was very good. And, their visual quality on rhizome growth was good. 3. After the application of CellCaSi, pH, CEC, Ex-cation of the applied soil showed increasing tendency with the little range, $SiO_2$content increasing tendency considerably, and organic matter content decreasing tendency compared with the control.ncy compared with the control.

Background: Panax notoginseng is a highly valued medicinal herb used widely in China and many Asian countries. Its root and rhizome have long been used for the treatment of cardiovascular and hematological diseases. Imaging the spatial distributions and dynamics of metabolites in heterogeneous plant tissues is significant for characterizing the metabolic networks of Panax notoginseng, and this will also provide a highly informative approach to understand the complex molecular changes in the processing of Panax notoginseng. Methods: Here, a high-sensitive MALDI-MS imaging method was developed and adopted to visualize the spatial distributions and spatiotemporal changes of metabolites in different botanical parts of Panax notoginseng. Results: A wide spectrum of metabolites including notoginsenosides, ginsenosides, amino acids, dencichine, gluconic acid, and low-molecular-weight organic acids were imaged in Panax notoginseng rhizome and root tissues for the first time. Moreover, the spatiotemporal alterations of metabolites during the steaming of Panax notoginseng root were also characterized in this study. And, a series of metabolites such as dencichine, arginine and glutamine that changed with the steaming of Panax notoginseng were successfully screened out and imaged. Conclusion: These spatially-resolved metabolite data not only enhance our understanding of the Panax notoginseng metabolic networks, but also provide direct evidence that a serious of metabolic alterations occurred during the steaming of Panax notoginseng.
