  • To study the effect of genotype of donor plants on anther culture, anthers of nine hybrid cultivars (Derby, Special, Bossanova, Minipaprika, Fiesta, Boogie, Phenlene, Kufrah, and Clarity) of sweet pepper (Capsicum annuum L.) were cultured in a petridish containing C medium (Sibi, Dumas De Vaulx medium) supplemented with 0.1 mg/L 2,4-D and 0.1 mg/L kinetin, 3% sucrose and 0.32% Phytagel. The cultures were incubated in the dark at $35^{\circ}C$ for seven days, and then cultured at $25^{\circ}C$ with a photoperiod of 16 hr. daylength for 40 days. Frequency of callus formation and plant regeneration was varied among cultivars. Callus formation was ranged from 6% in Phenlene to 69.8% in Kufrah. The highest percentage of regenerated plantlets was obtained in cv. Phenlene (2.67%) followed by Bossanova (2.41%). Result of ploidy analysis; chromosome number observation and flowcytometry analysis, showed that haploid plants could be developed from all of these hybrid cultivars except cv. Fiesta, where highest percentage of haploid plants were obtained in Minipaprika (40%) followed by cv. Bossanova (36.1%). Haploid plants derived from these hybrid cultivars contained single set of chromosome (12 in numbers), higher stomata density (numbers), and smaller sized stomata as compare to diploid plants. The mean length of stomata was 26.9 ${\mu}m$ in haploid plants and 35.7 ${\mu}m$ in diploids.

  • This study conducted a survey on 163 parents in Korea to investigate their interest in plants, experience in growing plants, and perception on horticultural activity programs (HAP) for their children. Most children (80.4%) of the respondents had experience participating in HAPs, and most of their experience occurred during school hours in preschool educational institutions more than once a month (60.3%). The more interest in plants and experience in growing plants the parents had, the more experience the preschoolers had in participating in HAPs, which implies that the experience of the parents with plants affected their children's participation in HAPs. Parents' most preferred location of HAPs was preschool educational institutions, and most preferred time was school hours with a frequency of more than once a week (57.1%), which is more frequent than the current status of HAPs in preschool educational institutions. Parents also responded that the most preferred instructors of HAP has are those with a professional background in horticulture. Among the activities in HAP for preschoolers, parents most preferred cooking (M = 4.05) activity, and they did not dislike any of the activities. They responded that the facilities for HAP needed to be improved to make HAP more active in preschool educational institutions. Overall, based on the current results, developing suitable HAPs and facilities for preschoolers, fostering professional HAP instructors, and educating parents about horticulture would enhance HAPs in preschool educational institutions, thus providing preschoolers with many benefits of HAPs.

  • This study investigated in the vascular plants of special protection zones (the native land of Iris koreana in Gaeamsa Temple and Soeppulbawi Rock) of Byeonsanbando National Park and identified the whole flora. The numbers of vascular plants were summarized as 255 taxa including 71 families, 166 genera, 222 species, 2 subspecies, 27 varieties and 4 forms. Woody plants were identified as 114 taxa (44.7%) and herbaceous plants as 141 taxa (55.3%). A total of 178 taxa were identified in the area of Gaeamsa Temple, and 184 taxa were found in the Soeppulbawi Rock. As a legal protected species, the endangered wild plant II grade Iris koreana designated by the Ministry of Environment was confirmed. A total of 6 taxa of rare plants were identified, each of which was divided into 1 taxa of critically endangered (CR; Iris koreana), 1 taxa of vulnerable (VU; Ilex cornuta), and 4 taxa of least concern (LC; Asarum maculatum, Viola albida, Chionanthus retusa and Tricyrtis macropoda). The Korean endemic plants were 11 taxa (Populus tomentiglandulosa, Lonicera subsessilis, Carex okamotoi, etc.). In the specific plants by floristic region were 38 taxa, a degree I were 23 taxa (Euscaphis japonica, Hedera rhombea, Lophatherum gracile, etc.), 7 taxa of a degree II (Viola violacea, Ainsliaea apiculata, Cephalanthera falcata, etc.), 6 taxa of a degree III (Ilex cornuta, Callicarpa mollis, Mitchella undulata, etc.), 1 taxa of a degree IV (Carex remotiuscula), 1 taxa of a degree V (Iris koreana). The Iris koreana special protection area that is more natural and healthier than any other areas in Byeonsanbando National Park. Therefore, it should be possible to continue its role as a special protection area through regular monitoring in the future.

  • Observations on reproduction of Rhodochorton purpureum (Lightfoot) Rosenvinge (Acrochaetiaceae, Rhodophyta) was carried out with plants from Hokkaido, Japan. This species produces no monosporangia both in nature and culture, even though it does tetrasporangia commonly. The plants from Nemuro produce neither sporangia nor gametangia, and thus vegetative reproduction is the only known way to propagate themselves. It is suggested that the vegetative reproduction occurs in nature by fragmentation of vegetative filaments after development of a rhizoid. Several different modes of rhizoid production are described. The plants from Akkeshi and Oshoro (I) produce tetrasporangia that develop into plants producing only tetrasporangia. The plants from Muroran and Oshoro (II) produce tetrasporangia that develop into gametophytes. Gametophytes of R. purpureum from Muroran produce tetrasporangia as well as spermatangia or carpogonia. Such tetrasporangia on gametophytes are presumed to be mitotic.

  • The purpose of this research is to analyze the methods of the decorations using module plants in interior spaces. This research produced 18 types of the module plant decoration: considering the classifications of module plants(soil, hydroculture, moss), directions of module plants (up, side, down), assembling ways of module plants (horizontal, vertical). Applying these 18 types to the interior space decoration (floor stand, wall attach, ceiling hanging), 54 types were classified. After that, 150 cases of the decoration using module plants in interior spaces were collected and analyzed. In result, the cases were belong to 25 types of 54 types. The important types were the types to be able to decorate wide area of walls or ceilings without occupying floor area: SOIL-UP-VERTICAL, HYDROCULTURE-UP-VERTICAL, MOSS-SIDE-VERTICAL. These types were the decorations with function of bio-filter for air cleaning. Special types were SOIL-SIDE-HORIZONTAL, SOIL-SIDE-VERTICAL with soil developed not to pour and SOIL-DOWN-HORIZONTAL, SOIL-DOWN-VERTICAL with lucks not to pour soil. Plants will be used widely in interior design because of the awareness of eco-friendly design. The strength that module plants are portable, changable, able to exchange parts helps users to maintain plants in interior spaces. For designers, module plants are flexible materials in order to make variety of forms to adjust to interior spaces. The results of this research about methods of the decorations using module plants in interior spaces are useful to designers who want to design interior spaces eco-friendly and user-friendly.

  • This study investigated species formation and their vegetation on the roadsides of 1100 Road and 5 16 Road in Hallasan National Park from August 2004 to December 2006 to provide basic data for distributional attribute of the naturalized plants. The vascular plants investigated on the roadsides of Hallasan National Park were found to be 62 families, 145 genera, 197 taxa in total, in which naturalized plants were recorded as 11 families, 29 genera, and 37 taxa. The floristic formation at 1100 Roadside was composed of Festuca arundinacea-Dactylis glomerata association, which was again divided into Trifolium pratense-Plantago lanceolata sub-association and Sasa quelpaertensis-Gleichenia japonica sub-association. The florisitic composition of the 5 16 Roadside was sorted as Festuca arundinacea-Dactylis glomerata association, Oplismenus undulatifolius-Potentilla fragarisiiforlia, elatior association, Ambrosia artemisiifolia, and etatior-Persicaria thunbergii association. Among the naturalized plants distributed at this area, the annual plant accounts for 51.4%[19 taxa] and the plant of European origin accounts for 70.3%[26 taxa]. As for the background of the introduction of these plants, the case of introduction for forage or a mixture with grain and for pasture was 35.1% and 21.6% respectively, showing higher introduction circumstances than others. As shown in the study, most of the roadsides were occupied by the naturalized plants- Festuca arundinacea and Dactylis glomerata association and various naturalized plants; thus we can assume that it's because Festuca arundinacea and Dactylis glomerata association were mostly used for re-vegetation of the destroyed areas due to road construction or expansion or road maintenance and improvement project.
