Objectives : Lysimachia mauritiana Lam. is known as a medicinal plant native to Korea that has antioxidant, anticancer, antibacterial, and antiviral activities. However, until now, research on the cultivation technology of L. mauritiana is insufficient, and there are no research data on the systematic cultivation method and mass production of L. mauritiana. Therefore, this study aims to establish a cultivation system of L. mauritiana. Methods : The cultivation environment of open land and facilities according to the growth of L. mauritiana was compared and tested. In addition, the equivalence of the origin collection extract and the cultivation extract was evaluated through Ultra high performance liquid chromatography (UHPLC) patterns analysis according to cultivation and comparison of the effect of inhibiting respiratory inflammation using BEAS-2B human bronchial epithelial cells. Results : The cultivation technology system was established through cultivation research of L. mauritiana raw materials. In addition, as a result of comparing and evaluating the equivalence of cultivated plants and L. mauritiana raw materials for suppressing respiratory inflammation, the same results were confirmed, and the equivalence was confirmed as a result of analyzing the UHPLC pattern with L. mauritiana raw materials. Conclusions : This study suggests that extract from cultivation research of L. mauritiana plants, which are native to Korea, can be used as a health functional food or medicine to improve respiratory health.

Because Lysimachia mauritiana is not able to maintain the seed viablity for a long time, it has difficulties in using for the ornamental plants or landscape gardening. This study was conducted to elucidate the optimal germination conditions of Lysimachia mauritiana seeds. The germination rate of the seeds was higer in light condition than in dark one. In experment determining the proper germination temperature, the germination rates were 2.2%, 96.9% and 91.2% under 35$\circ $C, 25$\circ $C, and 20$\circ $C, respectively in light condition. The approprate temperature for the germination was 25$\circ $C in light. The decreases of germination rate with the increase of the preservation periods was able to recover by priming pretreated with NaCl solution and KNO$_{3}$ + K$_{3}$H$_{2}$PO mixed solutions. When the storage period was 300 days, the germination rate was 75% without priming treatments. But the seeds primed with NaCl 0.1M and KNO$_{3}$ + K$_{3}$H$_{2}$PO mixed solutions 0.1M, showed germination rate above 90%. T$_{50}$ also was shorten from 5.25 without priming to 3.78 with NaCl 0.1M. Seed priming may induce earlier sprouts and increase germination rate of long-preserved seeds of native wild plants.

Three plant species, Aster sphathulifolius, Sedum oryzifolium, and Lysimachia mauritiana, native to the Dokdo Islands in South Korea, were examined for rhizosphere microorganisms by using 16S rDNA sequences. Nine species of rhizosphere microorganisms were isolated from the three native plant species, respectively. Phylogenetic analysis showed that the microorganisms could be classified into 19 species belonging to four phyla (Actinobacteria, Bacteroidetes, Firmicutes and Proteobacteria), and the characteristics of the microbes were confirmed. Rhizosphere microorganisms from the six orders (Bacillales, Corynebacteriales, Flavobacteriales, Micrococcales, Oceanospirillales, and Rhodobacterales) were isolated from S. oryzifolium. From L. mauritiana, microbes belonging to the seven orders (Bacillales, Flavobacteriales, Micrococcales, Oceanospirillales, Rhizobiales, and Rhodobacterales) were isolated. From A. sphathulifolius, the six orders of rhizosphere microorganisms (Alteromonadales, Bacillales, Corynebacteriales, Flavobacteriales, Micrococcales, and Rhizobiales) were isolated. These data showed that Actinobacteria and Proteobacteria were the dominant phyla for the rhizosphere of all three plants. To confirm the bacterial diversity in rhizospheres, Shannon's diversity index (H') was used at the genus level. In these data, the rhizosphere from S. oryzifolium and L. mauritiana had more diverse bacteria compared to that from A. sphathulifolius.

This study is carried out to make the environmentally affinitive porous planting block for revegetation and to make a effective program for greening plans. The summary is shown below. 1. In order to get stronger intensity and distribute proper porosity in the block for planting, the cements mixed with fine soil were used and the finer in soil grains gives the stronger in intensity of the cements. Use of the furnace slag cements instead of the portland cements showed relatively stronger in intensity of the block. The intensity of the block became stronger when the mixed ratio of the cements to soil is 5 : 1, but the pore space ratio was lower. The percolate pH of the portland cements after one month of treatment was 13.1 but the percolate pH of the furnace slag cements was shown lower. To mold proper porous planting blocks, the proper combination of additives such as the dehydrating agent, elastic agent and adhesives into the mixture of cements and soil gives better effectives. 2. After molding the porous planting blocks, it gave a better result when the grains of the filler made of peat moss, upland soil and compound fertilizer were smaller than 2 mm in size. Shaking of the filling materials also gave the better result, but it took more time and cost much more. Therefore, it was better when the filling materials were mixed with water first then flew down for stuffing. 3. It was necessary to cover with soil after seeding or planting on the porous planting blocks. The proper thickness of the soil to help root development and keep moisture is about 3~5 cm. 4. The plants for planting on the porous planting block were required stronger in the growth condition of their roots and their environmental adaptability. The average germination percentage and rate of Platycodon grandiflorum on the porous planting block were 88.8% and 85% accordingly and their rate is very uniform. The germination rates of Dianthus superbus var. longicalycinus and Taraxacum officinale were more than 50%. These grass species, Chelidonium majus var. asiaticum, Lysimachia mauritiana and Scabiosa mansenensis were the suggested biennial grasses in the planting area where exchanging of the seedling or nursery plants was not necessary because their germination rates were 59.3, 45.6 and 40.3% accordingly. Viola kapsanensis, Chrysanthemum sp., Taraxacum sp. and Iris ensata var. spontanea are the grass species that could be used by seeding for greening. However, the germination rate of Solidago virga-aurea var. asiatica, Aster scaber and Lythrum anceps were lower than 10%. The coverage ratio of Ixeris stolonifera is more than 80% after 60 days seeding and the root length of most of species are more than 10 cm except Iris ensata var. spontanea and Platycodon grandiflorum because their root developed thicker than other species.
