In order to evaluate the taxonomical relevance of seeds morphological characteristics, a macroand micro-morphological study was conducted on seeds of Korean Vicia (Fabacea). We collected 19 taxa of genus Vicia distributed in Korea and introduced one taxa from USDA. The morphological characteristic and testa texture of seeds were investigated using a Stereo-microscope (SM) and Scanning Electron Microscope (SEM). Most of Vicia seeds were found spherical or oblong and some seeds were oval and subglose. The largest seed was V. chosenensis ($4.3{\times}3.6{\times}2.6mm$), and the smallest was V. teterasperma ($1.7{\times}1.7{\times}1.5mm$). V. chosenensis and V. hirsuta were separated from other Vicia species by having a shiny in seed finish. In hilum shape, 14 species have linear and V. sepium was distinguished by having a circumlinear. In testa texture, they developed papilae, only V. hirsuta has lophate in level type. Deposition of the sheet-like debris between the papilae was observed in V. chosenensis, V. cracca, and V. unijuga. Polymorphism information content (PIC) values of the 13 qualitative morphological characters (QMC) were in the range of 0.0950 to 8863 with an average of 0.4611. PIC value of seed shape, seed colour, hilum colour were 0.7403, 0.8177, 0.883 respectively. Cluster analysis based on QMC detected three main clades. V. cracca, V. amurensis, V. amoena were involved in Group 1 and V. unijuga f. minor, V. unijuga, V. unijuga f. angustifolia, V. sepium, V. hirticalycina, V. hirsuta, V. linearfolia, V. chosenensis, V. pseudorobus, V. venosa var. cuspidata were involved in Group 2. V. nipponica, V. japonica, V. villosa, V. dasicarpa, V. bungei, V. angustifolia, V. tetrasperma were clustered in Group 3. Our research suggests that morphological characteristic and testa texture of seeds could be used as definers for the identification of genus Vicia.

The microstructure observation of seed surface structure is needed for protocols of breaking dormancy of seeds with physical dormancy. The seeds of Rubus species are surrounded by a thick, hard endocarp; together, the seed and endocarp make up the stone. We evaluate stone characteristics of 18 species of Rubus through optical microscopic observation, and correlate different stone characteristics with endocarp thickness. As a result of stone size comparison, Rubus species were classified as big stones group including R. parvifolius and R. idaeus, small stones group including R. longisepalus var. longisepalus, R. corchorifolius and R. hirsutus, and middle stones group including rest of the species. The result of this study revealed that stone size and the endocarp thickness in Rubus species was various characteristics in each species. Furthermore stone size and stone weight were also well correlated endocarp thickness and result indicated that heavy stones had harder endocarp than lighter one. Thus from the result of this study it can be presumed that only one stone characteristic approach may be sufficient to estimate other characteristics in Rubus.

Soybean sprouts have been a considered a nutrient-rich vegetable for hundreds of years. To evaluate the seedlot quality of soybean sprouts grown, and to evaluate a method for reducing the presence of improper seeds in soybean seedlots, microbes associated with soybean sprout rot were isolated from samples collected. Morphological characteristics and gas chromatography profiles of the cultured fungal and bacterial strains were identified. Eight types of improper seeds were identified: purple stain(Ps), black rot(Br), seed coat black spot(Cb), wrinkled seed(Ws), brown hilum(Bh), seed coat fracture(Cf), unripe seed(Us), and brown seed coat(Bc). The improper seeds were also dipped into 15%, 20%, and 25% NaCl solutions, as well as a saturated solution of NaCl, for 1min. As the NaCl concentration increased, the number of floating improper seeds increased as well. The highest floating rates were observed for the Cf seeds.

This text was analyzed and investigated the morphological character, production time and germination characteristic of seed that collect in Chungnam, in order to offer the basic informations for slope restoration and revegetation using Indigofera amblyantha of wild shrub. Legume was cylindrical type and length 31.5mm, width 2.5mm, and seed number of per legume was full ripe 5.5, unripe 0.9. Seed was elliptical type and length 2.4mm, width 1.7mm, and weight of 1,000 seeds was 5.9g. Because seed matured within December and next year January, optimum time of seed production was in mid of January. In the treatment $H_2SO_4$ of 15 minutes, seed germination rate was the highest as 91.0%, and seed germination time (days) was the shortest as 6.7 days. Seed germination time by temperature was the shortest from $25^{\circ}C$. Therefore, seed germination of Indigofera amblyantha was very useful in the treatment $H_2SO_4$ of 15 minutes from $25^{\circ}C$ temperature.

This study was carried out to get basic information about the morphological and production characteristics of fennel populations different origin under different ecological conditions in Hungary. The Korean population can be registered as a medium high genotype and showed a more accelerated growth characters than Hungarian taxon and the two populations have a medium homogeneity $(CV\;=\;4{\sim}22%)$. In the second year plant height in Hungarian taxon was significantly higher than that of the Korean population. The shooting dynamic of individual plants might be heterogeneous in both taxa and the Korean population was not only shorter in the height but had also less shoots by 16% than the Hungarian one. The Hungarian taxon exceeded the umbel size and numbers to the Korean one (by 3.62 cm in the average) and the variability in the populations was high $(CV\;=\;29{\sim}49%)$. Seed size was proved to be also a discriminative feature between the examined taxa. With small deviations (CV < 2) the Hungarian population produced seeds longer by 38%. Homogeneity in the populations was dependent more on the vegetation years and on the characteristics measured but less on the origins, respectively.

The National Agrobiodiversity Center (NAS, RDA, Republic of Korea) has continually collected new valuable genetic resources. In this study, we regenerated conserved kidney bean (Phaseolus vulgaris L.) germplasm which couldn't be available because of seed quantity and quality, and we also surveyed their morphological characters for the sustainable utilization. A total of 431 kidney bean accessions were regenerated and 18 morphological traits were surveyed according to the characterization guideline of RDA Genebank. Among the surveyed traits, flowering time ranged from May 23 to September 4 and 73.8% of tested accessions were mainly flowering in June. The maturity time ranged from July 1 to October 15 and main flowering time was July (91.4%). For plant type, 270 accs (62.6%) were climbing type followed by medium type of 86 accs (20.0%) and dwarf type of 65 accs (15.1%). The seed coat colors were various; yellow (34.6%), white (22.3%), brown (17.9%), red (10.7%), black (5.8%), violet (11%), pink (1.4%), navy (0.9%). Principal component analysis indicated that five principal components (PCs) with Eigen values >1 accounted for more than 65.8% variability. The first PC was more related to growth habits such as growth type, flowering time, and plant type. The second and third PCs showed higher values of the pigment characters such as seed coat color, flower color, and pod color. In fourth and fifty PCs, there were the higher positive values of the pod shapes. Our results provided insight into the characteristics kidney beans, thus the utilization basis of kidney beans might be elevated for bio-industry.
