    This study was performed to select the effective plant for phytoremediation of heavy metal contaminated areas. After cultivation of fifteen Compositae plants on soil contaminated with heavy metals for 8 weeks, the growth response and accumulation ability of each parts for heavy metal, such as arsenic, cadmium, copper, lead, and zinc were analyzed. Except Adiantum capillus-veneris, growth of Aster incisus, Coreopsis drumondii), Dendranthema indicum, Saussurea pulchella were relatively fine. Arsenic accumulation ability was the highest by Artemisia gmelini (25.52 ㎎·㎏-1 DW) in underground part, and D. sichotense (3.35 ㎎·㎏-1) in aerial part. Cadmium was the highest by Aster magnus (2.50 ㎎·㎏-1) in aerial part. Aerial and underground part of S. pulchella showed the highest copper accumulation (24.29, 99.92 ㎎·㎏-1). In lead, 1.43 (A. magnus)∼5.00 ㎎‧kg-1 (S. deltoides) were accumulated in aerial part among fifteen Compositae plants. Aster hayatae (140.09 ㎎·㎏-1), Aster yomena (109.07 ㎎·㎏-1), A. magnus (100.21 ㎎·㎏-1) are absorbed more than 100 ㎎·㎏-1 of Zinc. Therefore, they are considered to be phytoremediation material of zinc contaminated areas. - COLLAPSE

    An efficient shoot regeneration condition for pea cv. ‘Sparkle’ was developed by using optimum explant, plant growth regulator concentrations, and pretreatment of BA onto explant. The average shoot number per explant showed the highest on two kinds of shoot induction media (MSB5 media containing 2 ㎎/L BA and a combination of 2 ㎎/L BA and 1 ㎎/L TDZ) when cotyledonary node explants were cultured. Moreover, the pretreatment of explant in 200 ㎎/L BA solution was found to be more effective in shoot induction than that of non-pretreatment. By histological study, cell division and proto-meristem were formed near the surface of the sub-epidermal and epidermal cell layers of cotyledonary node in earlier than 3 days after culture. The analysis of genetic stability of regenerants by using thirteen ISSR markers showed that in vitro regenerated plants showed polymorphism with 8.3% compared with their mother plants. - COLLAPSE

    This study was conducted to provide a basic data such as leaf morphological characteristics, total 110 individual trees selected from 11 wild population, for selective breeding. As a result of investigation of the twenty morphological characteristics of the leaf, there were statistically significant differences in all leaf characteristics among the populations. Especially, Mt. Mani population had larger leaf length (LL), width (LW) and area (LAR) than other populations. On the other hand, Mt. Beakwoon and Mt. Duryun had smaller leaf size (LL, LW and LAR) among the populations. Its principal component analysis (PCA) results showed that it represented 72.9% accumulated explanation from three principal component. The characteristics such as leaf area, leaf length and leaf width were highly contributed for classification among populations. According to the cluster analysis, the natural S. alnifolia populations were classified into five groups and Mt. Mani population was different from the other population. - COLLAPSE

    This study was conducted to establish a domestic cultivation system of a newly introduced yam bean (Pachyrhizus erosus L.). Growth and yield were investigated in response to various cultural practices, such as seedling raising, planting distance, pinching, and flower pruning. Optimum conditions for raising of seedling were an average temperature of 22℃ for 30 days. Considering of the raising efficiency and the convenience of transplanting, 128 cells per tray was a suitable size. When pinching at a height of 120 ㎝ from late July to early August, yield increased by 22% compared to no pinching. Flower pruning between late August and early September increased the number of tubers and tuber yield by 32% in comparison with no flower pruning. Yam bean seedlings planted at 50 ㎝× 30 ㎝ spacing resulted in 30% yield increase as compared to wider spacing of 100 ㎝× 30 ㎝. Our results thus suggested that the optimal combination of cultural practices (50 × 30 ㎝ planting distance, pinching at 120 ㎝ height, and one time of flower pruning) increase profitability by 107%. All these results suggest high possibility of yam bean as a new income crop in Korea. - COLLAPSE

    In the process of adapting climate change, the government needs to provide policy and technical support necessary for growing promising crops imported from abroad. Therefore, this study was conducted to survey and analyze the conditions of growth of imported foreign crops and to derive response tasks. As a result, tropical and subtropical vegetables were cultivated 18 crops in 920 farms in 321 ha area (in 2015 year). The cultivation scale decreased in the order of Curcuma aromatica, Momordica charantia, Asparagus aethiopicus, Allium hookeri and Herbs. Tropical and subtropical fruits were cultivated 9 crops in 264 farms in 106.5 ha area (in 2015 year). Special and medicinal crops introduced abroad cultivated 10 crops in 753 farms in 276.3 ha area (in 2015 year). The cultivation scale decreased in the order of Curcuma longa, Glycyrrhiza uralensis, Lepidium meyenii and Moringa oleifera. For the stable settlement of domestic growth of tropical and subtropical crops introduced abroad, there should be safety and economic feasibility in terms of the cultivation environment according to the domestic culture adaptation test. Consideration needs to be given to the use of locally grown products in Korea, the securing of distribution and sales markets, and the competitiveness of imported products. - COLLAPSE

    The purpose of this study was to establish the in vitro propagation system by shoot tip culture of six Hosta species native to Korea (Hosta capitata (Koidz.) Nakai, H. clausa Nakai, H. jonesii M.G.Chung, H. minor (Baker) Nakai, H. venusta F.Maek., and H. yingeri S.B.Jones) for mass proliferation and a new cultivar development. The shoot tips of each Hosta species were cultured on MS medium containing eight combinations of 0.5, 1.0, 2.0, 4.0 ㎎/L BA with 0.1 ㎎/L NAA, 0.1, 0.5, 1.0, 2.0 ㎎/L TDZ with 0.1 ㎎/L NAA, and without any PGRs (control). They were investigated on callus, somatic embryo, crown bud, differentiation and growth of shoot and root, total fresh weight after 8 weeks of culture. In all six Hosta species, callus and somatic embryo induction rate and multiple shooting rate of the PGRs treatment group were higher than that of the control group. The highest number of differentiated shoots were obtained on medium supplemented with 2.0 ㎎/L TDZ in H. capitata (5.4), 1.0 ㎎/L TDZ in H. clausa and H. jonesii (3.3 and 5.8, respectively), 0.5 ㎎/L BA in H. minor (11.1), 1.0 ㎎/L BA and 0.1 ㎎/L TDZ in H. venusta (8.1), and 0.5 ㎎/L TDZ in H. yingeri (9.8). In somatic embryo formation, the PGRs treatment group of H. jonesii and H. yingeri were more effective than the control group, and the effects were relatively less in H. capitata, H. clausa Nakai, H. minor, H. venusta. Crown bud formation of four Hosta species (H.capitata, H. clausa, H. jonesiig, and H. yingeri) were also higher in the PGRs treatment group than in the control group. Crown bud formation of four Hosta species (H.capitata, H. clausa, H. jonesiig, and H. yingeri) were also higher in the PGRs treatment group than in the control group. H. clausa showed no significant effect on callus and shoot differentiation regardless of the type and concentration of cytokinin, but slightly increased in formation of crown bud in TDZ. - COLLAPSE

    Two unrecorded alien plants, Melilotus officinalis (L.) Lam. and M. indicus (L.) All. (Leguminosae) were found in Korea. M. officinalis is native to Eurasia and widely distributed in agricultural regions throughout the world. M. indicus is native to Mediterranean and Southwestern Europe, and naturalized in temperate regions all over the world. These species are morphologically similar to M. suaveolens (Jeon-dong-ssa-ri). However, M. officinalis is distinguished from M. suaveolens by transverse nerved legumes, definite ovary stalks, and five to eight number of ovules in ovary. M. indicus is also distinguished from M. suaveolens by smaller size of flowers, broadly triangular calyx teeth, globose legumes, and minutely papillose seeds. The local name of M. officinalis and M. indicus were given as “Ju-reum-jeon-dong-ssa-ri” and “Jom-jeon-dong-ssa-ri” based on transverse nerved legumes and overall smaller size than M. suaveolens, respectively. The descriptions on morphological characters and photographs at the habitat of M. officinalis and M. indicus are provided. - COLLAPSE
