Forage sorghum (Sorghum bicolor x S. bicolor) was cultivated for knowing the effect of alum sludge application on its root growth in a mountainous site, Kumsan. And the results obtained are as follows: The available P205 content in the soil seemed to decrease with the advance of level of alum sludge application. And plant P content decreased with the advance of sludge application without phosphate fertilizer. With phosphate fertilizer, root number of the forage was greater than that without the fertilizer. The root growth of forage sorghum was the highest with NPK and the least in control and alum application, and it is not recommended to apply NPK and alum together for the growth of the forage root. (Key words : Root, Sorghum, Mineral, Sludge, Kumsan)

Sorghum bicolor L. Moench(Sorghum, Su-Su) is a major cereal food crop used in many parts of the world. It is used as a human food resource and folk medicines in Asia and Africa. The stem of sorghum has been used as a digestive aid and an anti-diarrheal agent. Sorghum hybrids contain high levels of diverse phenolic compounds that may provide health benefits. High levels of polyflavanols, anthocyanins, phenolic acids, and other antioxidant compounds have been reported in sorghums, which have also been shown to possess various biological activities such as anti-mutagenic, anti-carcinogenic, and HMG-CoA reductase inhibitory activities. In an in vitro experiment, we examined mice splenocyte proliferation and production of three types of cytokine($IL-1{\beta},\;IL-6,\;TNF-{\alpha}$) by peritoneal macrophages cultured with ethanol and water extracts of Sorghum bicolor L. Moench. A single cell suspension of splenocytes was prepared and the cell proliferation of the splenocytes was examined by MTT assay. The splenocyte proliferation was increased when water extracts of Sorghum bicolor L. Moench were used as supplements in all concentrations investigated. The production of cytokine($IL-1{\beta},\;IL-6,\;TNF-{\alpha}$) by activated peritoneal macrophage was detected by ELISA using the cytokine kit. $IL-1{\beta},\;IL-6,\;and\;TNF-{\alpha}$ production by activated macrophages were increased by supplementation with Sorghum bicolor L. Moench water extracts. This study suggests that supplementation of with Sorghum bicolor L. Moench water extracts may enhance immune function by regulating the splenocyte proliferation and enhancing the cytokine production by activated macrophages in vitro.

To establish the organic cultivation of pepper using green manure crops, this work studied the growth characteristics and yield of green manure crops, mineral composition of green manure crops, mineral uptake in shoots of green manure crops, chemical composition in soil of green manure crops, and the growth characteristics and yield of pepper in vinyl house. Shoot dry weight of green manure crops was higher level in Sorghum bicolor and Sorghum than in Crotalaria juncea and Glycine max. Also, the roots were spread deeply into soil in Sorghum bicolor and Sorghum. Density of root-knot nematodes in rhizosphere of green manure crops was significantly more decrease in Crotalaria juncea and Sorghum than in Glycine max and Sorghum bicolor. Total nitrogen and CaO content of green manure crops was significantly higher in Crotalaria juncea and Glycine max than in Sorghum bicolor and Sorghum. $K_2O$ content was significantly higher in Sorghum bicolor and Sorghum than in Crotalaria juncea and Glycine max. MgO content was not significant difference at all green manure crops. Cations content ratio of $K_2O$ : CaO : MgO was 3.4 : 1.4 : 1. Total nitrogen uptake in shoots of green manure crops was high level in Glycine max, Sorghum bicolor and Sorghum compared with in Crotalaria juncea. $K_2O$ and MgO uptake was significantly higher in Sorghum bicolor and Sorghum than in Crotalaria juncea and Glycine max. Value of pH in soil of green manure crops was more increase in Crotalaria juncea and Glycine max than in Sorghum bicolor, Sorghum and control, but after cultivation of pepper pH in soil was recovered with initial soil pH before seeding of green manure crops. EC value in control, green manure crops, and pepper cultivation decreased by 44%, 15~18%, and 38~61% level, respectively, compared with initial soil of green manure crops treatment. K content in soil of control, Crotalaria juncea and Glycine max cultivation was increased by 14%, but the K content in soil of Sorghum bicolor and Sorghum decreased by 24~38%. Cation exchange capacity (CEC) in soil of Crotalaria juncea and Sorghum bicolor decreased by 11%, but CEC in soil of Glycine max, Sorghum and control increased by 11%. Harvest fruit yield was higher in Crotalaria juncea, Glycine max, and Sorghum bicolor cultivation than in control and Sorghum.

An experiment of alum sludge application was carried out on a mountainous site, to know its effect on the growth of forage sorghum hybrid, Pioneer 93 1 (Sorghum bicolor x S. bicolor). When alum sludge with 80% water content was applied at the level of 133 ton per ha, the effect of the application on the growth of Pioneer 931 was much smaller than that of chemical fertilizer. But Eresh yield of the forage, with the sludge application, was greater than that without fertilizer when the soil is not fertile. But when the soil was comparatively fertile, the sludge application gave an adverse affect on the growth of the forage plant. The content of exchangeable K in the soil has a very close positive relation with the Eresh yield and plant height of the plant, while that of exchangeable Ca has a close negative relation with those growing factors. There was a tendency of yield decrease of the forage plant, when alum or compost was applied with NPK to the comparatively infertile soil especially for alum sludge. As a result, when soil is not fertile more attention will be necessary for applying alum sludge with chemical fertilizers. But to soil with better fertility, it is recommended to use alum sludge with chemical fertilizer to obtain more yield of the forage plant.

This study was performed to evaluate the effect of Sorghum bicolor L. Moench(Sorghum, su-su) extracts on mouse immune cell activation. As ex vivo experiment, different concentrations(0, 50, 500mg/kg B.W.) of Sorghum bicolor L. Moench water extracts were orally administrated into mouse every other day for four weeks. The proliferation of mouse splenocytes, the number of plaque forming cells(PFC) and the cytokine IL-1β production by activated macrophage were used as indices for immunocompetence. Splenocyte proliferation was enhanced in mouse orally administrated with 50mg/kg B.W./day concentration compared to that of control group. Especially, the highest proliferation of spleoncyte was seen in the mouse orally administrated at the concentration of 50mg/kg B.W./day. The number of plaque forming cells(PFC) to SRBC were significantly enhanced when compared with control group. Also, the mouse of Sorghum bicolor L. Moench water extracts 50mg/kg B.W./day supplementation group with LPS stimulation enhanced level of IL-1$\beta$ cytokine production. This study suggest that supplementation of Sorghum bicolor L. Moench water extracts may enhance the immune function by regulating the splenocytes proliferation, increasing the number of PFC and enhancing the cytokine production by activated macrophage.

Fatty acid compositions of Setaria italica, Panirum miliaceum and Sorghum bicolor were determined with total lipids extracted. Total lipid content of Setaria italica, Panium miliaceum and Sorghum bicolor were 3.9%(w/w), 2.7%(w/w) and 2.3%(w/w), respectively. Total lipids were fractionated into neutral lipids, glycolipids and phospholipids by the silicic acid column chromatography. Neutral lipids were the most abundant component. Among fatty acids separated by GC, linoleic acid was determined as a major fraction in Setaria italica, Panicum miliaceum and Sorghum bicolor. Palmitic acid and oleic acid were also separated as second major components. In Setaria italica, behenic acid was separated from the phospholipid fraction and myristic acid from the neutral lipid fraction. Linolenic acid was not detected in all the samples.

The LIM domain-containing proteins are dominantly found in plants and play a significant role in various biological processes such as gene transcription as well as actin cytoskeletal organization. Nevertheless, genome-wide identification as well as functional analysis of the LIM gene family have not yet been reported in the economically important plant sorghum (Sorghum bicolor L.). Therefore, we conducted an in silico identification and characterization of LIM genes in S. bicolor genome using integrated bioinformatics approaches. Based on phylogenetic tree analysis and conserved domain, we identified five LIM genes in S. bicolor (SbLIM) genome corresponding to Arabidopsis LIM (AtLIM) genes. The conserved domain, motif as well as gene structure analyses of the SbLIM gene family showed the similarity within the SbLIM and AtLIM members. The gene ontology (GO) enrichment study revealed that the candidate LIM genes are directly involved in cytoskeletal organization and various other important biological as well as molecular pathways. Some important families of regulating transcription factors such as ERF, MYB, WRKY, NAC, bZIP, C2H2, Dof, and G2-like were detected by analyzing their interaction network with identified SbLIM genes. The cis-acting regulatory elements related to predicted SbLIM genes were identified as responsive to light, hormones, stress, and other functions. The present study will provide valuable useful information about LIM genes in sorghum which would pave the way for the future study of functional pathways of candidate SbLIM genes as well as their regulatory factors in wet-lab experiments.

This experiment was conducted to provide comparative data on the newly imported thirteen sorghum-sudangrass hybrids(Sorghum bicolor(L.) Moench), TE Goldmaker sorghum hybrid (S. Bicolor (L.) Moench), NC+ 88SS sudangrass hybrid (S, bicolor (L.) Moench), Supermill pearlmillet (Pennisetum americanum (L.) Leeke) and teosinte (Euchlaena mexicana Schrad,) in comparison with the check variety Pioneer 988 sorghum-sudangrass hybrid for dry matter yield, protein content, in vitro dry matter digestibility(IVDMD), and other desirable agronomic characteristics, SX-17 and NC+855 gave significantly higher dry matter yield than the check variety. There was no significant difference in total dry matter yield of the remaining 14 varieties with the exception of teosinte and TE Goldmaker which had the lowest yield. The most varieties were moderately resistant to leaf diseases although differences exist among varieties. No diseases were found in pearlmillet and teosinte, but NC+ 88SS was very susceptible to leaf blight. The mean percent crude protein of sorghum-sudangrass hybrids was lower than that of pearlmillet and sorghum hybrid, but was higher than that of sudangrass hybrid, The IVDMD of G-83F, TE Goldmaker, teosinte and HW 5111 was higher than that of the check variety. There was no consistent relationship between the percent of crude protein and IVDMD of the summer annual grasses.

The EtOAc soluble fraction from the stem of Sorghum bicolor showed a strong free radical scavenging activity. Five major compounds were isolated from this fraction. They were identified by spectral data as methyl ferulate (1), methyl p-hydroxycinnamate (2), p-hydroxybenzaldehyde (3), tricin (4), and quercetin 3,4 -dimethyl ether (5). Among these compounds, 1 exhibited a strong, free radical scavenging activity on 1, 1-diphenyl-2-picrylhydrazyl (DPPH) with an $IC_50$ value of 0.7 $\mu$M. We further studied the effects of these isolated compounds on the lipid peroxidation in rat liver microsomes induced by non-enzymatic method. All five compounds showed anti-lipid peroxidation activity ($IC_50$ values of 0.5, 0.4, 0.3 and 0.3 $\mu$ M, respectively).
