This study was carried out to evaluate ecological growth characteristics of forty castor bean collections for biodiesel utilization. The emergence date and it's rate of collections was 15-16 days and 82.5%, respectively. It took 63-68 days from emergence to flowering. Stem length was ranged from 173 to 251 cm with an average 211.8 cm. The average stem diameter was 24.2 cm, and showed the high occurrence as 52.5% at the 20.4-24.9 cm. The node number was widely distributed as 13-22 and the average node number was 18.9. The seed numbers were widely distributed as 7-33ea, and the average liter weight of seed was 502.9 g of which minimum weight was 432.3 g and maximum weight was 572.5 g, and the gap between maximum and minimum was 140.2 g. It showed high difference. The 100 grain weight was distributed as 20.3 g-38.3 g which showed high differences between small grain and large grain collections. The seed numbers per plant were varied as 72 at the minimum and 1,011 at the maximum number, and average seed number was 465.2. The total yields of seed per plant were varied as 20 g-266.2 g, and the average yields were 128.1 g.

Seed priming is a useful technique for rapid and uniform seed germination as well as early seedling establishment. This experiment was conducted to find out the optimum condition for Sorbus alnifolia seed priming with four concentrations of four reagents in germination property and seedling growth performance. The results are summarized as follows: Percent germination (PG) varied 2.67% to 24.67%, and S. alnifolia seeds had the highest PG in the treatment that were primed in 100mM
solution for 2 days. Mean germination time was the shortest in 200 mM
solution for 2 days. Seed priming with
solutions increased germination speed (GS) and germination performance index (GPI) compared with non-primed seeds. Especially seed primed with 100 mM
solution for 2 days showed the highest GS and GPI. The highest relative growth rate (RGR) and seedling vigor index (SVI) was significantly (p<0.05) different from the control and other treatments, respectively. RGR of height (0.0071) and root collar diameter (0.0141) of seedling from primed seeds were the highest in 400 mM NaCl solution for 2 days. The highest SVI (5.43) was observed in the seedlings from seeds primed in 100 mM
solution for 2 days. Consequently, the optimum reagent and concentration were
and 100 mM for the effective germination and seedling growth in S. alnifolia

The aim of this study was to examine geographic variation to support a genetic resource conservation plan of rare endemic Picea jezoensis (Siebold & Zucc.) Carriere. Three populations of P. jezoensis were analysed using multivariate analysis for 7 characteristics of needle morphology. In the morphological characters, seven characters of needle were 15.11 mm (needle length), 1.43 mm (needle width), 0.42 mm (needle thickness), 10.9 (length / width of needle), 3.6 (width / thickness of needle), 0.47 mm (Distance between resin duct and vascular), 17.4 ea. (number of stomata row), respectively. Nested analysis showed that were statistically significant differences among populations as well as among individuals within populations in 6 quantitative characters. In 5 of 7 characters, variance components among populations were higher than those among individuals within populations. Cluster analysis using complete linkage method showed two groups (Mt. Gyebang populations was genetically distinct from the other two populations) to Euclidean distance 0.4. Among principal components, primary 2 principal components appeared to be major variables because of the loading contribution of 100%.

This study was conducted to examine the difference in yield and size of enlarged rhizome according to the kinds of native white lotuses. Four white lotuses (Nelumbo nucifera) were collected from 4 different sites, Jeonbuk Jeonju ('Garam'), Jeonnam Muan ('Hoesan'), Chungnam Buyeo ('Ihnchuisa'), and Chungnam Cheongyang('Cheongyang'). Each enlarged rhizome was planted in an area of 3.3
on 10. April, 2007 and digged out on 19. February, 2008. The yield of enlarged rhizome was in the order of Hoesan (3.0 kg/
), Cheongyang (2.5 kg/
), Garam (2.0 kg/
) and Ihnchuisa (1.0 kg/
). The number of enlarged rhizomes was in the order of Ihnchuisa (4.9/
), Garam (4.3/
), Hoesan (4.2/
) and Cheongyang (4.1/
). Total number of nodes in the enlarged rhizomes were much more in the order of Hoesan (17.0/
), Ihnchuisa (16.0/
), Cheongyang (15.3/
) and Garam (14.1/
). Component ratio of enlarged rhizome length below 50cm for Ihnchuisa, Garam, Hoesan and Cheongyang were 76.3%, 53.0%, 38.2% and 40.3% respectively. Native white lotus had a longer enlarged rhizome in the first node than the other nodes, and their enlarged rhizome length and width became thin. And it became thick and short from the second node of enlarged rhizome. Accordingly the amount of enlarged rhizomes 'Hoesan' was extremely much than others.

Korean Journal of Plant Resources, volume 22, issue 1, 2009, Pages 71~77
Antioxidative activity and
-amylase inhibitory activity were investigated in the methanol extracts of 289 species of angiosperm plants native to Jeju Island in order to select the plant species containing bioactive materials for functional foods or medicines. The antioxidative activity, estimated by the DPPH radical scavenging capacity, was high in the galla of Rhus chinensis, the fruit of Platycarya strobilacea, and the stem of Cedrela sinensis. Particularly, the antioxidative activity of Rhus chinensis galla (94.2
0.8%) was very high even though compared to those of BHA (61.7
0.6%) and ascorbic acid (53.6
-amylase inhibitory activity was 80% or above in 9 species including Cornus macrophylla (stem, leaf), Distylium racemosum (leaf) and Vaccinium oldhami (leaf). These results suggest that these plants could be potentially utilizable to develop bioactive materials for functional foods or medicines.

Dokdo was formed since when four million six hundred thousand to two million five hundred thousand. Dokdo, Ulreung Island and the mainland in Korea are not touch each other since the formation, therefore, Dokdo are very important island for discussion of plant evolution from plant geography point of view. Plants of Dokdo was enlisted as 60 taxa, 27 families, 52 genera, 50 species and 10 varieties. The naturalized plants of a wide sense is composed of 25 taxa, two tree species as Lonicera morrowii and Elaeagnus macrophylla, and 23 herbs. The naturalized plants were identified of 5 species as Sonchus oleraceus, Brassica juncea var. integrifolia, Rumex crispus, Chenopodium album, and Bromus unioloides. Total naturalized plants are 32 taxa, ratio of total naturalized plants per a existing species was 60 percentage. Accordingly Vegetational environment of Dokdo was interpreted very incomplete state as well as severe ecological disturb by invade species. Preparation of a regulating plan on naturalized plants and concern of a policy decision are requested in the conservational dimension for native species in Dongdo. For the conservation of native species in Dokdo, there are prepared that a regulating plan as block of the influx and eradication etc. and a policy decision of naturalized plants are prepared for view of the conservation for native species in Dokdo.

This study examined the halophyte community and soil analysis according to habitat in representative 18 salt marshes of southern and western coasts of Korea from July 2006 to April 2008 and suggested basic materials for vegetational restoration of these aras. First, the survey area was classified into coastal and estuarine marshes. Then, the coastal marshes were classified into clay marsh, sand gravel marsh, and sand marsh, and the esturarine marshes, into salt swamp and estuary marsh. Major plant communities according to habitat pattern were Phragmites communis, Carex scabrifolia, and Suaeda japonica community in the clay marsh; Phragmites communis, Zoysia sinica, Carex scabrifolia, Salicornia herbacea, Artemisia fukudo, Suaeda martima community in the sand gravel marsh; Elymus mollis, Carex kobomugi, and Vitex rotundifolia community in the sand mars; Phragmites communis, Zoysia sinica, Suaeda martima, and Carex scabrifolia community in the salt swamp, and Suaeda japonica, Phragmites communis, Carex scabrifolia, and Suaeda asparagoides community in the estuary marsh. The soil environment of halophyte community area showed a difference to soil and halophyte community according to habitat characteristics of halophyte. Thus, to restore salt mashes in the coast area, it is advantageous for the stable settlement, germination, and growth of halophyte to grasp physical and physicochemical characteristics of habitat soil in the salt marshes, to select halophyte suitable to these habitat conditions, and to expand gradually in the natural vegetation area after transplantation.
