A plant growth promoting rhizobacterium, Bacillus vallismortis BS07M, was formulated as a clay pellet (CP) to evaluate its pepper growth promotion and induced resistance against various diseases under field and storage conditions. Peppers were grown in 50-hole tray containing potting mixture with CP in seedling raising stage, and then it was transplanted into a field. After transplanting, pepper plants treated with CP in seedling raising stage increased shoot growth and reduced disease severity caused by Phytophthora capsici in detached pepper leaves compared to untreated control. Moreover, treatment with CP in seedling raising stage increased fruit weight per plant; after harvesting, pepper fruits shown reduced diameter of lesions by Colletotrichum acutatum, and occurrance of soft rot in storage condition. These results indicated that CP could affect plant growth and induced resistance in pepper plants under field condition, and maintenance of fruit during storage.

To establish the optimum condition for plant regeneration from somatic embryos of Acanthopanax sessiliflorus Rupr. et Maxim, a medicinal plant, somatic embryos were induced from zygotic embryo-derived embryogenic callus in hormoen-free MS medium. To induce plantlet conversion, cotyledonary somatic embryos were cultured on MS solid medium with GA$_3$at various concentrations (0~10 mg/L) for three weeks. Plantlets were transferred to 1/3 MS solid medium with 0.5% charcoal for 7 weeks. Stem length was increased proportionally to the concentration and treatment period of GA$_3$. Also, the highest leaf width (8.9 mm) and leaf number (2.84) of plantlet were obtained when plantlets were converted on 5,10 mg/L GA$_3$pretreatments, respectively. The highest plant conversion frequency (66.7%) was obtained when the somatic embryos were cultured on medium containing 5 mg/L GA$_3$ for 3 weeks and then were transferred to 1/3 MS medium with 0.5% charcoal. The highest survival rate of soil transfer was 90% when plantlets were regenerated on medium with 5 mg/L GA$_3$ for 3 weeks and then transferred to plastic pots containing vermiculite and sand mixture for 4 weeks.

Effect of perfluidone(2-methyl-4-phenylsulphonyltrifluoromethylsulphoanilide) and bifenox(2,4-dichlorophenyl-3-methoxycarbonyl-4-nitrophenylether) mixture on weed control and plant growth and yield of transplanted rice was determined. Perfluidone-bifenox mixture applied at 75-105 g a.i./10a controlled effectively perennial weeds such as Sagittaria pygmaea Miq., Potamogeton dtstinctus A. Benn., Cyperus serotinus Rottb, Eleocharis kuroguwai Ohwi, including most annual weeds, but did not control Sagittaria trifolia L.. There was no phytotoxicity caused by perfluidone-bifenox mixture when applied at 100-140 g a.i./10a. The mixture at 150-210 g a.i./10a caused crop injury, but did not affect the yield. Phytotoxicity due to the mixture decreased as the application time was delayed.

A total of ninety six pigs ($L{\times}Y{\times}D$, 20.92(2.13kg average initial body weight) were used in a 16-week performance growth assay to determine the effect of supplemental medicinal plane (Artemisia, Acanthopanax and Garlic) on growth performance, IGF-1 of serum and carcass characteristics in finishing pigs. The dietary treatments were included 1) CON (basal diet; Control), 2) MP1 (basal diet added $0.02\%$ of medicinal plant mixtures), 3) MP2 (basal diet added $0.04\%$ of medicinal plant mixtures) and 4) MP3 (basal diet added $0.06\%$ of medicinal plant mixtures). Through entire experimental period, as medicinal plants mixture (MP) increased, there was a decrease (linear, P<0.08) in average daily feed intake and an increase (linear, P<0.02; quadratic, P<0.08) in gain/feed. The backfat thickness tended to decrease in pigs fed MP diet compared to pigs fed CON diet (linear, P<0.09; quadratic, P<0.01). Increasing medicinal plane mixture tended to increase in IGF-1 content in serum (linear, P<0.09). The hunter $a^{*}$ (redness) (linear, P<0.01) and $b^{*}$ (yellowness) (linear, P<0.02) values of longissimus muscle were affected by the dietary MP treatments. The color of longissimus muscle was higher in the dietary MP treatments than that of the muscle in the control diet (linear, P<0.03). In conclusion, the result obtained from this feeding triad suggest that the medicinal plants mixture supplementation below $0.06\%$ in diets for growing-finishing pigs can be improved growth performance, IGF-1 and meat quality.

The co-combustion of coal and three kinds of RDFs(Refuse Plastic Fuel) mixture has been experimented in a commercially operating CFB coal boiler respectively and the pollutant emissions such as SOx, NOx, TSP and dioxine were measured at the stack. The mixing ratio with coal was 7.5% RPF, 7.5% RDF and 10% SDF respectively. During co-combustion, dioxine emission level was very low and SOx, NOx and TSP were decreased comparing the single coal combustion. Emitting dioxine concentration was proportioned to the chlorine content of RDF. These RPF, SDF and RDF could be determined to be a good alternative fuel of general coal.

In the screening of antiviral materials produced by actinomycetes, an isolate named B25 was fond to produce an antibiotic substance ASA, which showed a strong inhibitory activity against tobacco mosaic virus (TMV) infection. ASA was purified from culture broth of B25 by silica gel column chromatography, preparative TLC, and reversed phase HPLC. Also MS, IR, UV spectrum, and melting point of ASA were determined and analysed. ASA was white powder soluble in dimethyl sulfoxide, chloroform, and ethyl acetate, having absorption peaks at 223 and 328 nm in UV-VIS spectrum, and had a molecular weight of 548. ASA showed strong inhibitory effect on TMV infection when it was applied as a mixture of TMV to the upper surface of leaves of a local lesion host (Nicotiana tabacum c. Xanthi-nc). It also showed antimicrobial effect against yeast and some phytopathogenic fungi.

In order to observe the phosphate metabolism in chloroplast, the contents of inorganic phosphate and various compounds in chloroplast from spinach leaf tissues were investigated during the reaction in the light and dark in the reaction mixture and the turnover of phosphate in chloroplast was compared with that of whole cell system: 1. The phosphorus of DNA in chloroplast appears to be transferred from inorganic phosphate, while in whole cell system from phosphate pool. 2. $^{32}P-phosphate$ content of acid soluble fraction in chloroplast as well as in whole cell system was more increased in the light than dark during the reaction. It was noted to be caused by the stimulation of sugar phosphate synthesis in the light. 3. It was confirmed that polyphosphate exists in chloroplast as well as whole cell. Acid insoluble polyphosphate content in whole cell system was significantly decreased during the reaction and the similar tendency was also observed in chloroplst. It is, therefore, considered that acid insoluble polyphosphate also play an most important role as a phosphate pool respectively in chloroplast and in cytoplasm. 4. Protein and lipid phosphorus in chloroplast as well as whole cell system were transferred from acid insoluble polyphosphate.

Callus-inducing ability of Alnus hirsuta was examined by culturing various tissues (leaf, hypocotyl, cotyledon and seed) on NT (Nagata & Takebe) medium, supplemented with 2.5$\mu$M 2,4-D. Leaf-originated callus was cultured on media varying in auxin (IBA and NAA) and cytokinin (BAP) concentrations to examine the effects of auxin and cytokinin on callus growth. Maximum growth was obtained at 10 $\mu$M IBA+10$\mu$M BAP and 10$\mu$M NAA without cytokinin. Cell suspensions established from cotyledon-originated callus yielded viable protoplasts after incubation for 16-18 hours in an enzyme mixture (1% (w/v) Onozuka R-10 0.5% (w/v) Macerozyme, CPW salts and 13% (w/v) mannitol, pH 5.8). Protoplasts were cultured on NT medium, supplemented with glucose, hormones and coconut milk. After 6 weeks of culture, protoplasts sustained cell divisions to form microcallus, which showed various colors from red to white.

The co-combustion of coal and RPF(Refuse Plastic Fuel) mixture has been experimented in a commercially operating CFB coal boiler and the emissions such as SOx, NOx, TSP and dioxine were measured at the stack. The experimented RPF was supplied by domestic RPF company that is commercially producing RPF pellet from the wasted plastics. Up to 15% of total coal was substituted to RPF and no trouble was happened during normal boiler operation. SOx and NOx concentration was reduced about $15{\sim}20$% and TSP(Total Suspended Particle) was drastically reduced about 30% during co-combustion. Dioxine concentration at mixing ratio of 7.5% was $0.0487ng{\sim}TEQ/Sm^3$ ($O_2$, 12%) that satisfied governmental emission regulation.
