  • Prunus speciosa (Koidz.) Nakai belonging to Prunoideae of Rosaceae, a species previously unrecorded in Korean flora, is described. Prunus speciosa (Koidz.) Nakai is similar to Prunus sargentii Rehder and Prunus jamasakura Siebold ex Koidz., but different because it has toothed lobes of calyx tubes with the apex of leaf serrations aristate. This species is naturalized widely in the eastern parts of Jeju Island but is endemic to Japan.

  • Background and objective: Particulate matter (PM) has a fatal effect on health. There have been many studies on the use of plants such as trees and shrubs as eco-friendly and sustainable biofilter for the removal of PM. In forming more green space, ground cover plants play an important role in multi-layered planting. This study was conducted to investigate the ability of plants to reduce PM, targeting Korean native ground cover plants with high availability in urban green spaces. Methods: For 4 species of Asteraceae, 4 species of Liliaceae, and 3 species of Rosaceae, one species of plants at a time were placed in an acrylic chamber (800 × 800 × 1000 mm, L × W × H) modeling an indoor space. After the injection of PM, the amount of PM remaining in the chamber over time was investigated. Results: For all three types of PM (PM10, PM2.5, PM1), significant difference occurred in the amount of PM remaining between plant species after 1 hour in the Liliaceae chamber, 3 hours in the Asteraceae chamber, and 5 hours in the Rosaceae chamber. With Liliaceae, the leaf area and the amount of PM remaining in the chamber showed a negative (-) correlation. With the Asteraceae and Rosaceae, there was a weak negative correlation between the leaf area and the amount of PM remaining in the chamber. Conclusion: When using ground cover plants as a biofilter to remove PM, it is considered effective to select a species with a large total leaf area, especially for Liliaceae.

  • In order to compare species-specific calcium metabolism, we collected 127 species belonging to 40 different families grown on various habitats including saline, limestone, wetland during the 1996 vegetation period, and analyzed their inorganic ion contents. Plants investigated were divided into 5 groups according to their physiological properties: 1) Chenopodiaceae, Aizoaceae, Caryophyllaceae, Portulacaceae and Phytolaccaceae of Centrospermales and Polygonaceae (Polygonales had a little water-soluble $Ca^{2+}$ but contained high contents of insoluble $Ca^{2+}$ particularly as Ca-oxalate (Chenopodiaceae type), 2) Some plant species such as Rosaceae produced oxalate in amounts insufficient to precipitate all incoming $Ca^{2+}$ and thus contained a surplus of dissolved $Ca^{2+}$ (Rosaceae type), 3) The contents of water-soluble $Ca^{2+}$ in plant species of Crassulaceae. Plantaginaceae, Asclepiadaceae, and Zygophyllaceae were equal to or greater than those of K ($K/Ca{\leq}1$; Crassulaceae type), and 4) K/Ca ratios of Compositae were significantly fluctuated depending on species and soil $Ca^{2+}$ level of their habitats (Compositae type). 5) Certain monocots (Gramineae, Cyperaceae, Juncaceae), in contrast to the dicotyledonous plant families mentioned above, showed a very distinct type of calcium metabolism, that is, the K/Ca ratios of 8~10 were maintained indifferently in the species and their habitat types (Graminae type). These results plants within the same taxon have similar physiological aspects as weel as morphological attributes. To understand calcium metabolism of certain plant species, therefore, it is desirable to approach on the basis of physiological concept (calciotroph or calciophobe) rather than the ecological one (calcicole or calcifuge).

  • The antioxidant activities and total phenolics of four Rosaceae species Pourthiaea villosa (Thunb.) Decne, Sorbus commixta Hedlund, Sorbaria sorbifolia var. stellipila Maxim and Pyrus pyrifolia (Burm.f.) Nakai were determined. Phenolic content (polyphenol and flavonoid), radical scavenging activities [2,2-Diphenyl-1-picrylhydrazyl (DPPH) and 2,2-azino-bis (3-ethylnezthiazoline-6-sulfoic acid) (ABTS)] and ferrous ion chelating effect were evaluated. Total polyphenol and flavonoid contents were highest in Pourthiaea villosa (Thunb.) Decne and lowest in Pyrus pyrifolia (Burm.f.) Nakai. Phenolic contents of Pourthiaea villosa (Thunb.) Decne was $331.45{\pm}7.78$ and $90.4{\pm}3.5mg{\cdot}g^{-1}$. DPPH and ABTS radical scavenging activities were found to be lowest in Sorbus commixta Hedlund whereas Sorbaria sorbifolia var. stellipila Maxim and Pourthiaea villosa (Thunb.) Decne showed relatively good DPPH and ABTS radical scavenging activities. Ferrous ion chelating effect was highest in Pyrus pyrifolia (Burm.f.) Nakai ($1.05{\pm}0.04mg{\cdot}ml^{-1}$) and lowest in Sorbus commixta Hundlund ($4.22{\pm}0.71mg{\cdot}ml^{-1}$).

  • Prunus glandulosa Thunb. [=Cerasus glandulosa (Thunb.) Sokolov] (Rosaceae) is native to the warmtemperate region of China (Anhui, Fujian, Guangdong, Guangxi, Guizhou, Hebei, Henan, Jiangsu, Shaanxi, Shandong, Sichuan, Yunnan, and Zhejiang Provinces). It is naturalized in the United States (i.e. Alabama, Michigan and North Carolina) and Canada (Ontario). This species, previously only recorded as introduced or cultivated plants on the Korean Peninsula, was confirmed to be naturally distributed in the southwestern coast islands(i.e. Geomun-do, Chuja-do and an uninhabited island in Shinan-gun of Jeollanam-do). Prunus glandulosa Thunb. is distinguished from a related taxon P. japonica var. nakaii (H. Lév.) Rehder by pedicel 8-12 (-16) mm long, linear stipules, glabrous style, and pink petals. The morphological characters and illustration of P. glandulosa Thunb. are provided with line drawings and photographs from the natural habitat. In addition, it is likely that a new habitat will be found by plant biodiversity investigations through the southwestern coast islands. Further research is needed to determine its population size, distribution, and threats, as well as identify appropriate locations for conservation collection of germplasm.

  • Taxa of the herbivorus insect larvae and their foodplant species were surveyed in a temperate forest of Namhansansung Area, Sungnam City, Kyonggi Province, in 1994-1996 growing season, Sixty two taxa of insect larvae fed on leaves of 18 woody species in 11 families during three growing season. Larvae began to be detected from the mid-April when the leafing time began. The number of larvae taxa reached to the maximum value(32 taxa) early in May, 1994. It was the time that the value of specific leaf area reached to the maximum. It decreased up to 3-4 taxa in the mid-June. Taxa of insect larvae were different year by year even in the same season. Most of larvae fed on various plant species, suggesting that they were generalist or polyphagous species. Fagaceae, Betulaceae, Ulmaceae, Rosaceae. Aceraceae, Ericaceae, Oleaceae and Styracaceae were fed on by many taxa of insect larvae, while Euonymus spp. (Celastraceae). Lindera obtusiloba(Lauraceae) and Symplocos chinensis for. pilosa(Symplocaceae) were mainly fed on by a few taxon.. Erannis, Calospilos and Phigalia were observed to feed on various species, but Illiberis, Pryeria and Chalocosia fed on only Rosaceae, Euonymus spp.(Cerastraceae) and Symplocos chinensis for. pilosa(Symplocaceae), respectively. An unidentified larva was observed only on Lindera obtusiloba (Lauraceae).
