In order to investigate the host range of the mosaic disease of black locust in the Chunchon area, the sap of the mosaic-diseased leaves of black locust itself and the cowpea leaves infected with the above mentioned sap, were inoculated to 53 species of plants belong to 12 families. As to the result, no difference in infection was found as related to the virus sources, and the infection was recognized in 4 species of the family Chenopodiaceae and 8 species of the family Leguminosae. The plants recognized as hosts are as follows: the plants which showed local infection are Chenopodium album, Ch. ambrosioides, Ch. quinoa; the plants which showed systemic infection are Chenopodium amaranticolor, Phaseolus vulgaris, Robinia pseudo-acacia, Vigna sinensis; and Astragalus sinicus, Melilotus indicus, Phaseolus angularis, Pisum sativum and Vicia faba were recognized as carriers. Through investigating its host ranges and symptoms, this mosaic virus of black locust seems not to be regarded as the group of the black locust mosaic virus in southeastern Europe reported by Milinko et al (1961). And, too, it is thought hardly to exist in combination with the cowpea mosaic virus. It appears, therefore, that this mosaic virus was confined to that of black locust.

The methanol extracts of 25 leguminous seeds in vitro were evaluated for inhibitory activities against lens aldose reductase of Sprague Dawley male rats. The responses varied with both leguminous seed and concentration used. At the concentration of 0.1 mg/mL, the methanol extracts from Amphicaraea edgeworthii, Canavalia lineata, Gylcine max var. solitae, Glycine max var. yagkong, Glycine max var. hooktae, Glycine max var. bangkong, Glycine max var. geumdu, Glycine max var. chungtae, Glycine max var. mejukong, Glycine soja, Phaseolus radiatus var. geodu, Vicia tetrasperma, Vigna angulasis, and Vigna sinensis inhibited enzyme activity by greatertha 60%. In following study, at the concentration of 0.01 mg/mL, the extracts of C. lineata and V. tetraspermahad relatively strong inhibitory activity against aldose reductase. Because of their potent inhibitory activities, the activity of each solvent fraction from C. lineata and V. tetrasperma was determined, and the potent activity was showed from chloroform and hexane fractions, respectively. {TEX}$IC_{50}${/TEX} values of C. lineata and V. tetrasperma were 0.004 and 0.006 mg/mL, respectively. As a naturally occurring therapeutic agent, leguminous seeds described could be useful for developing new agents of antidiabetic complications.

Four leguminous crops grown in greenhouses and fields in Korea were surveyed from 2000 through 2002. Sclerotinia rot most severely occurred up to $60\%$ in Phaseolus vulgaris grown in greenhouses but occurred as low as $0-0.5\%$ in that grown in fields. Incidence of the disease in Pisum sativum grown in greenhouses ranged $1-5\%$, and that in Vicia Java and Vigna sinensis grown in fields was $0.8\%$ and $2\%$, respectively. Symptoms of Sclerotinia rot commonly developed on stems and pods of the crops. A total of 59 isolates of Sclerotinia species were obtained from diseased stems and pods of the crops. All of the isolates were identified as Sclerotinia sclerotiorum based on their morphological characteristics. Eight isolates of the fungus were tested for their pathogenicity to four host crops by artificial inoculation. All of the isolates induced rot symptoms on stems of the host crops tested, which were similar to those observed in the fields. The pathogenicity tests revealed that there was no significant difference in the susceptibility to the isolates among the leguminous crops tested This is the first formal report that S. sclerotiorum causes the Sclerotinia' rot of the four leguminous crops in Korea.

This experiment was carried out to compare chemical composition of corn-cowpea inter cropping and corn monocropping plants at different harvestion time and obtained the following results. 1. In both cropping systems, the contents of crude fat and nitrogen free extract (NFE) were significantly increased (P<0.01), while that of crude protein crude fiber and crude ash were decreased (P<0.01) with each harvesting time. 2. The acid detergent fiber (ADF) and crude fiber contents were decreased same patterns in growing period, however, according to maturing of corn ears the difference between ADF and crude fiber contents reduced. 3. At mature stage, crude protein yields per 10a in corn monocropping and corn-cowpea intercropping system were 127.6kg and 152.1kg, respectively. The difference of crude protein content between corn-cowpea intercropping and corn monocropping system was 19.2%. 4. TDN yields of each cropping system, at mature stage, obtained similar results and TDN yields per 10a of corn monocropping and corn-cowpea intercropping system were 1006.1kg and 990.1, respectively. 5. Conseqently, corn-cowpea intercropping system could be increased protein yield without decreasing of dry matter yield in comparison with corn monocropping system.

The growth characteristics and yield per unit area of two cropping systems, corn monoculture and 'wrnsoybean intercropping, were compared and the obtained results were as follows; 1.The two cultivation systems were not significantly different in leaf length, leaf width and length of internode at harvesting time. 2.The weight of stalk and the leaves of a plant were decreased with maturity, while the weight of ear was markedly increased. The patterns of relative ratio of each components were essentialy same in each cultivation systems. In corn monoculture, the percentages of stalk, leaf, and ear at final harvesting stage were 22.9, 13.7, and 63.4 and in corn-soybean intercropping, they were 21.8, 10.9, and 67.3 respectively. 3.Dry matter yield per unit area (kg/lOa) of intercropped corn at yellow stage was similar to that of monocultured corn (1, 483 kg/ 10a vs 1, 509 kg/ 10a). At ripe stage, however, the dry matter yield of intercropped plant was more than that of monocultured (1, 679 vs 1, 660 kg/ 10a). 4.The same pattern was observed in organic matter yield.

Background: This experiment aimed at assessing polyphenol-rich plant biomass to use in complete feed making for the feeding of ruminants. Methods: An in vitro ruminal evaluation of complete blocks (CFB) with (Acacia nilotica, Ziziphus nummularia leaves) and without (Vigna sinensis hay) polyphenol rich plant leaves was conducted by applying Menke's in vitro gas production (IVGP) technique. A total of six substrates, viz. three forages and three CFBs were subjected to in vitro ruminal fermentation in glass syringes to assess gas and methane production, substrate degradability, and rumen fermentation metabolites. Results: Total polyphenol content (g/Kg) was 163 in A. nilotica compared to 52.5 in Z. nummularia with a contrasting difference in tannin fractions, higher hydrolysable tannins (HT) in the former (140.1 vs 2.8) and higher condensed (CT) tannins in the later (28.3 vs 7.9). The potential gas production was lower with a higher lag phase (L) in CT containing Z. nummularia and the component feed block. A. nilotica alone and as a constituent of CFB produced higher total gas but with lower methane while the partitioning factor (PF) was higher in Z. nummularia and its CFB. Substrate digestibility (both DM and OM) was lower (P < 0.001) in Z. nummularia compared to other forages and CFBs. The fermentation metabolites showed a different pattern for forages and their CFBs. The forages showed higher TCA precipitable N and lower acetate: propionate ratio in Z. nummularia while the related trend was found in CFB with V. sinensis. Total volatile fatty acid concentration was higher (P < 0.001) in A. nilotica leaves than V. sinensis hay and Z. nummularia leaves. It has implication on widening the forage resources and providing opportunity to use forage biomass rich in polyphenolic constituents in judicious proportion for reducing methane and enhancing green livestock production. Conclusion: Above all, higher substrate degradability, propionate production, lower methanogenesis in CFB with A. nilotica leaves may be considered useful. Nevertheless, CFB with Z. nummularia also proved its usefulness with higher TCA precipitable N and PF. It has implication on widening the forage resources and providing opportunity to use polyphenol-rich forage biomass for reducing methane and enhancing green livestock production.
