  • A new cultivar of Euphorbia milii, 'Panorama' was developed at Cactus Research Institute, Gyeonggi-do Agricultural Research & Extension Services in 2009. 'Gabi' and 'Maxi' were crossed in 2001 and three $F_1$ seedlings were obtained. Pedigree selection was performed in 2002. One line was finally selected and named as 'Panorama' through the test of specific character from 2007 to 2009. The new cultivar 'Panorama' has green and pink colored bract, and it has 2~3 each of inflorescence number, 2.0 cm of bract width, 4.3 each of lateral shoot and 14.9 cm of plant height. Characters of the cultivar can be maintained by vegetative propagation.

  • The purpose of this study was to investigate the suitable parts for callus induction and optimal concentrations of growth regulators contained in the medium affecting shoot and rooting for the in vitro mass production of Haworthia maughanii. To determine suitable parts of the plant for callus induction, the leaves, flower bloom and flower stalks were cultured in MS medium at different concentrations of $0{\sim}2mgL^{-1}$ NAA and $0{\sim}2mgL^{-1}$ TDZ, respectively. All of the parts showed 100% callus formation rate at $NAA\;1mgL^{-1}$ and $TDZ\;1mgL^{-1}$ treatment, $NAA\;2mgL^{-1}$ and $TDZ\;2mgL^{-1}$ treatment and NAA 1 to $2mgL^{-1}$, respectively. While the rate of callus formation was high in all parts, the leaves were the most efficient to obtain most culture parts. $NAA\;0.1mg\;L^{-1}$ and $BA\;0.1mg\;L^{-1}$ treatments were the most effective in shoot formation with 22.0 shoots. In addition, multiple shoot propagation showed 16.3 shoots, the highest, with $NAA\;0.1mg\;L^{-1}$ and $BA\;0.1mg\;L^{-1}$ treatments. These results led us to speculate that the optimization of culture conditions was responsible for the mass propagation for in vitro cultures of Haworthia maughanii.

  • The objective of this study was to investigate the suitable parts for callus induction and optimal concentrations of growth regulators contained in the medium affecting shooting and rooting Echeveria laui and Echeveria elegans for in vitro mass production. To determine the suitable plant parts for callus induction, the leaves were divided into upper, medium and bottom parts and cultured on MS medium at different concentrations with $0{\sim}2mgL^{-1}\;NAA$ and $0{\sim}4 mgL^{-1}BA$. The upper and middle parts of leaves both showed 100% callus formation rate with $NAA\;1\;mgL^{-1}$ and $BA\;1\;mgL^{-1}$ treatment in E. laui. The middle parts of leaves showed 83.3% callus formation rate at $NAA\;2\;mgL^{-1}$ and BA 4 mgL-1 treatment in E. elegans. The shoot induction rate from callus was highest at $NAA\;0.1\;mgL^{-1}$ and $BA\;3\;mgL^{-1}$ treatment in E. laui and $NAA\;0.3\;mgL^{-1}$ in E. elegans. In addition, the number of shoots formation was 10.4 shoots high in $NAA\;1\;mgL^{-1}$ and $BA\;1\;mgL^{-1}$ treatment in E. laui and 12.0 shoots in most effective $NAA\;1\;mgL^{-1}$ and $BA\;0.1\;mgL^{-1}$ treatment in E. elegans. In the case of acclimatization of regenerated plant, growth characteristics did not show any significant difference (35 ~ 55%) shading with respect to the different ratio of substrate mixture, and it was determined that would be appropriate considered plant height and appearance preference of E. laui and E. elegans. It was established that the optimization of culture condition was responsible for the mass propagation in vitro cultures of E. laui and E. elegans.

  • Indoor gardening includes wall greening, terrariums, and flower arrangements. Among these types of indoor gardens, the terrarium is easy to access for the general public, but in Korea, because of the focus on esthetics, the original purpose of creating terrariums, which was to grow plants sustainably in an enclosed space, has been lost. In addition, miniaturization of plants is required to grow plants in an enclosed space. Since the available plant species suitable for a terrarium are limited, only plants such as succulents, cacti, and moss have been used. In this study, Bronze (X Graptosedum) was used, and these problems were solved using the following three methods: placement and growth of virus-free plants in the terrarium; extending the diversity of plants with minimal size that can be planted in terrariums; and reducing the price of in vitro plants with minimal size by achieving large-scale production. In particular, tissue-cultured succulents were developed into a Vivorium by replacing the tissue culture container and renewing the composition of the plant. This paper suggests a new indoor horticultural field, Vivorium, that can improve the current limitations of terrariums and make them more accessible to the general public. The introduction and popularization of new indoor gardening fields with the increase in single-person households and indoor activities in the Pandemic era can also improve psychological stability among people and in the society.

  • The purpose of this study was to investigate suitable parts for callus induction and optimal concentrations of growth regulators, contained in the medium affecting shoot and rooting for in vitro mass production of Haworthia truncata. Leaves and flower bud showed 100% callus formation rate at NAA $1{\sim}2mgL^{-1}$ treatment, and NAA $1mgL^{-1}$ + TDZ $2mgL^{-1}$ treatment. The flower stalk showed 75% callus formation rate, at NAA $2mgL^{-1}$ + TDZ $2mgL^{-1}$ treatment in H. truncata. While the rate of callus formation was high in leaves and flower bud, leaves were the most efficient in obtaining most culture parts. Shoot induction rate from callus was highest, at NAA $0.1mgL^{-1}$ treatment in H. truncata. Additionally, the number of shoots formation was 66.3 shoots high, in NAA $1mgL^{-1}$ + BA $0.1mgL^{-1}$ treatment in H. truncata. In the case of acclimatization of regenerated plant, growth characteristics did not show significant difference (95%) shading with respect to the different ratio of substrate mixture, and it was determined that would be appropriate, considering plant height and appearance preference of H. truncata. It was established that optimization of culture condition, was responsible for mass propagation in vitro cultures of H. truncata.

  • The succulent plants of Echeveria genus are in increasing demand worldwide, but it is difficult to supply good quality young plants throughout the year because propagation efficiencies are depend on cultivar and environmental factors. This study was carried out to investigate the propagation efficiencies of leaf cutting in Echeveria cultivars at different LED light qualities in a closed-type plant factory system. Leaf cuttings cut from stock plants of six difficult-to-propagated cultivars 'Afterglow (AG)', 'Berkeley Light (BL)', 'Mason (MS)', 'Subsessilis Light (SL)', 'Cream Tea (CT)', and 'Ben Badis (BB)' were put into cutting media in the plant factory system maintained at a temperature of $24{\pm}2^{\circ}C$ and relative humidity of $60{\pm}10%$, and watered with over-head irrigation twice a week. Cuttings were irradiated with sole or mixed red (R, 660 nm), blue (B, 450 nm), green (G, 530 nm), and far-red (FR, 730 nm) LEDs as follows: R10, R8+B2, R5+B5, R7+B2+FR1, and R7+B2+G1. PPFD just above the cuttings was $200{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$ and photoperiod was 16/8 (light/dark) hours. As a result, propagation efficiencies were dependent on cultivar. Rooting and shooting were relatively easy in 'SL' but shoot formation in 'AG' was very difficult. Light qualities from LEDs also affected plant regeneration. Light conditions with a higher ratio of B, R5+B5, R7+B2+FR1, and R7+B2+G1, promoted shoot formation and growth but inhibited rooting and root growth. R10 and R8+B2 with a higher ratio of R promoted rooting and root growth and inhibited shoot formation and growth of cuttings. In addition, the treatment with FR increased leaf size and biomass of the all plants. Therefore, further studies are needed to investigate the optimum compositions of LED light quality for the improvement of leaf cutting efficiency in difficultto-propagated Echeveria cultivars.

  • This study analyzed the physiological quality of Mesembryanthemum crystallinum (ice plant) extract. M. crystallinum is a succulent plant found in Africa, southern Europe, North America, South America, and Australia. It has known antidiabetic, antioxidant, and activation of lipid metabolism effects. Extracts from M. crystallinum were prepared with methanol (MCM), ethanol (MCE), hot water (MCHW), and methanol after hot water (MCHM) extractions. The yields of MCM, MCE, MCHW, and MCHM were 0.37, 0.33, 0.50, and 0.07%, respectively. To determine the biological activities of the extracts, mushroom tyrosinase, pancreatic lipase, 1,1-diphenyl-2-picryl hydrazyl (DPPH) radical scavenging, nitric oxide (NO) production, and α-glucosidase assays were conducted. The DPPH radical scavenging activity of the MCHW extract was 62.9% at a concentration of 400 μg/ml, which was the highest of all the extracts. The MCM extract showed the highest inhibition activity of α-glucosidase and NO production (56.6 and 57.2%, respectively). The pancreatic lipase inhibition of the MCE extract was similar to that of the MCM extract, with significant inhibition of 90%. The mushroom tyrosinase inhibition of all the extracts was very low (approximately 30%). These results suggest that extracts from M. crystallinum have antioxidant, anti-inflammatory, antiobesity, and antidiabetic activities. Thus, it may have potential as a functional food product and therapeutic potential as an antidiabetic or antiobesity agent.

  • Proper light intensity, potting media, fertilization level, and shade tolerance were investigated to develop Orostachys (Korean name, Nungyu bawisol) as a potted ornamental plant. The best plant growth was shown at 52% shading. Although plant growth decreased at 82% shading, ornamental value maintained at that shading rate, which indicate that O. 'Nungyu bawisol' has high shading tolerance. At over 90% shading, some of the plants died and showed decolorization and standing erect in leaves, resulting in a big decrease in ornamental value. Potting medium of decomposed granite (DG) : fertilizer-amended media (FAM) : river sand (RS) (6 : 2 : 2, v/v/v) showed the best growth in potted O. 'Nungyu bawisol'. Fresh weight of shoot part was 16 g in DG : FAM : RS (6 : 2 : 2, v/v/v), which was over 2 folds of those at the other medium. Drenching of Hyponex solution diluted by 1,000~2,000 folds 1 time per week brought the highest results in fresh weight, plant width, and runner number. Particularly, fresh weight of shoot part was 13 g higher than that of control (16 g). Leaf color tended to be darkened as concentration of Hyponex solution increased.

  • Korean Sedum formosanum N. E. Br. (Ju-geog-nip-gaet-bi-reum in Korean) was first recorded in 1887, 133 years ago. Since then, the species has not been collected and its current state has remained unclear. However, these plants were collected in 2020 and the corresponding taxonomic entity and distribution status were revealed. It is known to be distributed only in the southern region of Japan, the northern islands of the Philippines, and in Taiwan, with Taiwan being the collection site of the type specimen. However, on the basis of the findings of the fourth national natural environment survey, it has recently been established that this plant also grows in the crevices of rocks along the seashores of the Korean islands of Hataedo Island and Sangtaedo Island, Sinan-gun, Jeollanam-do. S. formosanum inhabiting Korea is a large succulent biennial that can attain a height of up to 65 cm and differs from its congeneric species in having erect follicles during the fruiting period. Notably, among the Korean Sedum species, S. formosanum is most similar to S. tosaense, although it can be distinguished from this species with respect to its monomorphic leaves that have rounded apices, and it also bears separate flowering and sterile stems. In this paper, we present a description and photographs of the Korean S. formosanum, indicate the differences between this and related species, and provide a key to related taxa.
