The inhibitory effects of vegetables, collected from Jinju district, on the growth of Listeria monocytogenes were investigated. Among 12 vegerables, garlic, leek, onion and cabbage were remarkably effective to inhibit the growth of the strain. Especially with the addition of extract equivalent 0.25g of raw garlic per ml broth, the population of the strain was decreased wignificantly, and completely inhibited with the addition of 0.625g or more. During the incubation with the addition of extract equivalent 0.25g of raw garlic per ml broth, the degree of inhibition was gradually increased with the lapse of time, and completely inhibited the growth of the strain after 48 hrs. While the pH value of treated broth remained unchanged almost, those of control were slightly reduced.

To investigate the effect of light intensity on the growth of shoots and roots, water and chlorophyll contents in the ginseng leaf were determined at 5%, l0%, 20%, 30% light transmittance rate (LTR) with 1,2 and 4 year-old ginseng plants in the field. Stem length, size of the leaf, water and chlorophyll contents were decreased as the increase of the light intensity in all ages of ginseng plants. The degree of decrease was severe in the one year-old ginseng compared to that of 2, or 4 year-old ginseng, while there was no difference between the 2 and 4 year-old plants. Root weight per plant was highest at 5% LTR in the one year-old plants, while it was at 20% LTR in the 2 and 4 year-old plants. Generally, demand of light for the growth of one year-old ginseng was lower than those of 2 or 4 year-old plants there was no difference of it among the ginseng plants older than 2 years.

These experiments were conducted to determine the effects of Sorghum allelopathic substances on the callus growh of several weeds and crops. 1. When substances extracted from allelopathic Sorghum(Sorghum bicolor L.) were treated on medium, growth of callus of several weeds and crops were in-hibited. The degree of inhibition differed depending on the genotypes, ranging from 50 to 90% com-pared with that of control. 2. The extracts of above 5% Sorghum inhibited the callus growth of Che-nopodium albun L., Commelina communis L., and .Ammaranthus retroflexus L.and showed in-hibition rate of above 70% in callus growth. These results indicate that we could investigate theallelopaihy effect by using in vitro system. 3. The suitable explant for callus induction fromallelopathic plants was immature embryos, the callus induction rate differed depending on the geno-type, growth regulators and concentrations. In general, the addition of 2, 4-D and NAA onto medium increased the rate and amount of callus.

In order to clarify the growth characteristic and Brix degree at different internodes, four varieties that are M81E 71-1, a Rio, a Sart and a Tamurama were seeded on, Apr. 5, Apr. 15, Apr. 25, May 5 and May 15, respectively. Delayed seeding increased plant hight and the growth pattern of the stem diameter and weight was tapesed off and lighted to upper location. Brix degree of internode was rapidly increased from just after heading date, and was slowly increased by rising upper side till before heading date. Brix degree of middle location(6th internode) was the highest of the stem in after heading date and interior side was the lowest. Brix percentage of 40∼45 days after heading had more than 15% in case of being seeded from Apr. 5 to May 5. Sweet sorghum that was seeded on May 15 was more than 17% in the Brix percentage of 35 days after heading and so the suitable seeding date in sourthern district was suggested on May 5. The plethora of soil moisture by rainfall was made decently lower Brix degree in 130∼140 days after seeding. Among the length and the diameter of internode, and Brix degree had negative correlation, between diameter and weight of internode were significantly positive correlation. But correlation coefficient had been a little bit different by varieties.

In order to produce ${\gamma}-linolenic$ acid by Mucor sp. KCTC 8405P. the fungus was cultivated in fed-batch culture with two phases. i.e., growth in yeast-like form and induction to hyphal growth by pH shift of the culture medium during cultivation. The synchronous growth of the fungus into the appropriate sizes was important for the high density cell culture of this dimorphic fungus. Dissolved oxygen concentration in the medium did not affect degree of unsaturation of fatty acids and ${\gamma}-linolenic$ acid content. Under the culture conditions applied in this experiment. the fungus was found to produce 100 g/l dry mycelia containing 40% of the lipids, where ${\gamma}-linolenic$ acid comprised about 9% of the total extractable fatty acids.

The proso millet is vulnerable to lodging due to high plant height and shallow root. A lodging results in a hard mechanical harvesting and yield loss. One of solutions on this problem is inhibition of internode elongation. The objective of this study was to set up use time and dose of prohexadium-calcium, is growth inhibitor. The experimental variety was Ibaekchal. The experiment design was a split-plot design with three replications. The treatments were as follow: Main-plots were 25 and 35 day after sowing(DAS) as use time and sub-plots were 0%, 50%, 100%(diluted solution of 1000 times, $1000{\ell}\;ha^{-1}$), 150% as dose. The amount of nitrogen, phosphate and potassium fertilization were 90, 70, $80kg\;ha^{-1}$, respectively. The size of high ridge and plant spacing were $90{\times}30cm$ and $60{\times}15cm$, respectively. Proso millet was sown on June 9, 2016 by hands and was adjusted at 2 plant per hill. The growth survey of vegetative growth stage was conducted at 1 day before treatment and with one week interval after treatment. Data were collected: (1) grain yield: weight of grain in $kg\;ha^{-1}$, (2) 1000 grain weight: average weight of 1000 grain, (3) plant height: distance from soil to top of panicle or leaf in cm, (4) ear length: distance from top of stem to top of ear in cm, (5) stem diameter: diameter of second internode (6) degree of lodging: percentage of lodging area, etc. Analyses of variance were performed using R version 3.3.1(https://www. r- project. org). The Duncan's multiple range test(DMR) was used to separate treatment means at P < 0.05. There was a significant difference in plant height and number of stem among the use time and dose of prohexadium-calcium during vegetative growth stage. At 25 DAS, the difference with no treatment increased until 25 day after treatment and decreased since then. The difference in number of stem increased until 18 day and decreased since 25 day. At 35 DAS, the difference with no treatment in plant height and number of stem increased until 22 day after treatment and decreased since then. We assumed that the effect of prohexadium-calcium was inhibition of internode elongation and promotion of tillering, continued untel 25day after treatment. At 25 DAS, the degree of lodging deceased to 100%, 30%, 10% and 0% as dose increased. At 35 DAS, the degree of lodging decreased to 100%, 20%, 0% and 0% as dose increased. At 25 DAS, the yield was 2910, 2710, 3190, $2310kg\;ha^{-1}$ among dose. At 35 DAS, the yield was 2750, 2630, 2220, $2050kg\;ha^{-1}$. We recommend that the optimum use time and dose of prohexadium-calcium for proso millet is 1000 times diluted solution of $1000{\ell}$ per ha at 25 day after sowing.

To investigate the damage on the black pine(Pinus thunbergii) by the air pollution around Ulsan Industrial Complex, forty-six plots were set up and the effects of air pollution were evaluated with the injured index of black pine. The injured index of black pine showing the degree of air pollution from 1987 to 1988 indicated that the central area of Yeochun-dong and Youngjam-dong were heavily damaged. The effective indicaters of black pine damage from air pollution in the order of importance were the color change of one-year-old branch, the ratio of fallen needle of two-year-old branch, the degree of reducing needle, and the degree of growing shoot growth. There was a reliable relationship between the content of $SO_3$ and F in the air and the injured index of black pine. There was no significant correlation between the injured index of the black pine and the content of chemical properties in soil.

Effects of hydrogenation in amorphous silicon rile growths on Solid Phase Crystallization (SPC) was investigated using x-ray diffractometry, energy dispersive Spectroscopy, and Raman spectrum. Interdiffusion of barium(Ba) and aluminum(Al) compounds of corning substrate was observed in both of rf sputtering and LFCVD films under the low temperature(580$^{\circ}C$) annealing. Low degree of crystallinity resulted from the interdiffusion was obtained. Highly applicable degree of crystallinity was obtained through the mechanical damage induced surface activation on amorphous silicon films. X-ray diffraction intensity of (111) orientation was used to characterize the degree of crystallinity of SPC. Nucleation and growth rate in SPC could be controllable through the employed surface treatment. IIydrogenated LPCVD films showed the superior crystallinity to non-hydrogenated sputtering films. Insignificant effects of activation treatment in sputtered film was of activation treatment in sputtered film was observed on SPC.
