A Hosta cultivar 'Neulpureum 1' was bred at the Korea National Arboretum, which produces new cultivars using vegetative propagation techniques. The new cultivar 'Neulpureum 1' was derived by crossing Hosta minor with Hosta 'Krossa Regal'. Among the induced leaf-color- and shape-modified hosta plants, the plants that exhibited deep-green color and small-bended leaves were selected. 'Neulpureum 1' maintained the deep-green leaves for longer than Hosta 'Krossa Regal'. Additionally, the plant height of 'Neulpureum 1' was shorter than that of Hosta 'Krossa Regal' and several leaves were observed on the new cultivar; therefore, it is likely to be used as a pot plant. The botanical characteristics were investigated for three years beginning 2012. A Hosta 'Neulpureum 1' can prove to be useful as a material for a pot plant or as ground cover plant at half-shadow place.

The purposes of this study are to comprehend the importance of policy in improving the operation of the public arboretum and survey the program satisfaction of participants and operators based on the case of the Daegu arboretum. According to the order of policy priority regarding the Daegu arboretum, the expansion of the education program topped the list with 0.155 points, followed by the establishment of a vision and goal, and the reestablishment of function, which scored 0.135 and 0.135 points, respectively. Fostering citizens' participation through volunteer work was in the upper ranks with 0.131 points. Building networks among public arboretums and constructing a research cooperation system with universities turned up with 0.09 and 0.075 points. As the result of program satisfaction, participants' satisfaction was around 0.66 points higher than that of operators' satisfaction. In the case of participants, comprehensive satisfaction, including that with the program operation method, was very high at 4.85 points. Out of the entire program, the operators were the most satisfied with the benefits. This study aims to share improvement plans for public arboretums constructed in urban areas, analyzing policy priorities and satisfaction related to the Daegu arboretum. The results of this study can be utilized as data for the improvement plans of public arboretums. If improvement plans for public arboretums are modeled with other follow-up case studies, it will help ensure that public arboretums become evolving rather than fixed areas for citizens.

A cryopreservation is an essential tool for preservation of germplasm. In this study, the possibility for cryopreservation of embryogenic cells of Siberian ginseng (Eleutherococcus senticosus) in liquid nitrogen (-196℃) was evaluated. The effects of glycerol and dimethyl sulfoxide (DMSO) at different concentrations (5%, 10% and 20%) as cryoprotectants on regrowth of cryopreserved E. senticosus embryogenic cells were tested. There was significant effect of cryoprotectants on regrowth of embryogenic cells (p=0.0019). The highest and lowest fresh mass gain were achieved when embryogenic cells were frozen with 10% DMSO and 5% glycerol (138.2±5.9 and 61.3±14.6, respectively). The effect of the cryoprotectants on the frequency embryo germination was tested. There was no significant difference between glycerol and DMSO (p=0.846). Three different concentrations of cryoprotectants did not significantly affect the frequency embryo germination (p=0.534). Finally, the genetic fidelity of the plantlets regenerated from non-cryopreserved and cryopreserved embryogenic cells was tested by random amplified polymorphic DNA (RAPD) and inter simple sequence repeat (ISSR) analysis. RAPD and ISSR analysises showed that there was no genetic variation among regenerants.

Adenostemma madurense DC. (Asteraceae, Adenostemma L.), which is known to be distributed in Japan, Taiwan, Thailand and Nepal was recently found on Jeju Island in Korea. It is morphologically allied to A. madurense but distinguished from A. lavenia (L.) Kuntze by having such characters as broadly ovate or ovate to oblong leaves, $15-21cm\;long{\times}7-12cm$ wide and smooth achenes with slightly muricate at the upper. Furthermore, A. madurense is found in dry mountain slopes in evergreen forests while Adenostemma lavenia occures in the wetland and side of pond. This taxon was named 'San-mul-meo-wi' in Korean based on its habitat. We provide a description, illustrations, photographs, and the key to the related species in Korea.
