  • Effects of garlic juice (GJ), ethanol- (GJAE) and ethyl ether extract of garlic juice (GJEE), onion juice (OJ) and ethanol extract of onion juice (OJAE), garlic juice+Merit Blue (GJ+MB), ethanol extract of garlic juice+Merit Blue (GJAE+MB), onion juice+Merit Blue (OJ+MB), ethanol extract of onion juice+Merit Blue (OJAE+MB), and Merit Blue (MB) on budbreak, flowering, and maturity of plastic house-grown 'Daebong' grapes (Vitis labruscana B.) were studied. MB alone and in combination with other formulae hastened the budbreak, and double application was more effective than single one. Most of the buds sprouted in early forcing, but percent budbreak in late forcing was very poor except for MB application. In early forcing, single application of MB in combination with other formulae was most effective for hastening flowering while the response to double application was not consistent, and even delayed the flowering except for OJAE, MB, and OJ+MB. In late forcing, single application of all dormancy-breaking agents, especially MB in combination with other formulae, hastened the flowering while flowering response to double application was inconsistent, and even delayed the flowering except for OJAE+MB and OJ. Although there were no significant differences in harvest date among treatments and the number of application in early forcing, single and double application of MB alone and in combination with other formulae, especially double application of OJAE+MB hastened the harvest date for 12 days in late forcing culture.

  • The object of this study was to determine the optimum concentrations of boron and IBA and dipping time, and to investigate the effect of combined-treatment of boron and IBA for the improvement of rooting of semi-hardwood cutting of Styrax japonica. The rooting percentage and the number of roots of cuttings increased with short dipping treatment of $7,000mg{\cdot}L^{-1}$ IBA and combined treatment of $100mg{\cdot}L^{-1}$ IBA and $20mg{\cdot}L^{-1}$ boron or $100mg{\cdot}L^{-1}$ IBA and $60mg{\cdot}L^{-1}$ boron. The rooting percentage, no. of roots and fresh weight were higher in combined treatment of boron and IBA than treatment of IBA alone. Either $100mg{\cdot}L^{-1}$ or $200mg{\cdot}L^{-1}$ was regarded as in appropriate level of IBA and the optimal dipping time was three hour in single treatment of IBA. It is concluded that the combined treatment of low concentrations of IBA and boron could be substituted for the treatment of high concentration IBA.

  • This research was performed to examine the effects of mixed espil and copper hydroxide for powdery mildew prevention on cucumber, tomato and pepper. On prevention effect for powdery mildew on cucumber, results revealed that mixed espil and copper hydroxide with a ratio of 4 : 1, disease incidence rate was 18.9% and prevention effect was 69.9%. Another treatment with a ratio of 8 : 1 showed an disease incidence rate of 18.1% and prevention effect of 71.1%, thus, showed great effectiveness. For powdery mildew on tomato, espil and copper hydroxide were mixed using the ratio 4 : 1, results showed an disease incidence rate of 12.4% and prevention effect of 85.3%. Treatment using the ratio of 8 : 1, results showed an disease incidence rate of 14.3% and prevention effect of 83.0%, thus, showed great effectiveness. For powdery mildew on redpepper, espil and copper hydroxide were mixed using the ratio of 4 : 1 with results showed disease incidence rate of 17.7% and prevention effect of 83.0%. From the results, this treatment is the most effective with the lowest attack rate and highest prevention effect. Deducing from the study, it was found out that using mixed espil and copper hydroxide using the ratios 4 : 1 or 8 : 1 are the most effective method for powdery mildew prevention. Mixed ratio of 4 : 1 or 8 : 1 was most effective for preventing powdery mildew on cucumber and tomato, while the espil and copper hydroxide ratio of 4 : 1 was the most effective method for powdery mildew prevention on pepper.

  • Zygotic embryos of Stewartia korean Nakai were cultured to determine the effects both of BA and NAA on adventitious shoot induction. Multiple shoots (about 11 per explant) were formed when the embryos were treated with 1.0 mg/L BA alone. On the other hand, NAA appeared to inhibit shoot induction when treated with BA. Adventitious shoots looked differ in form and color by the combinations of BA and NAA treated. When both BA and NAA were present, the shoots became short and developed dark color. The highest rooting was observed at 0.5mg/L NAA. The results could be useful for the establishment of in vitro regeneration system for Stewartia koreana Nakai.

  • Many farmers have been seeking alternatives to chemical fertilizer for successful organic fruit production. This experiment was carried out to investigate the replaceability of chemical fertilizer by cover crop and slurry composting biofiltration (SCB) liquid manure (LM) application in pear orchard. Three treatments were contained in this experiment; cover crop only and cover crop + LM treatment, and control (chemical fertilizer application). Dry weight and mineral contents of gramineous cover crops were significantly increased in LM-combined treatments than that of leguminous species. Bulk density of soil was decreased in rye + LM and hairy vetch + LM treatments, compared with each cover crop treatment. Soil pH was lowest in fertilizer treatment and soil nitrate content became similar between treatments after rainy season. Available soil phosphate was lower in cover crop and cover crop + LM treatmemts than control, but exchangeable Mg was higher. The mineral content and net assimilation rate of leaves showed no difference between the treatments. As a result, it is suggested that the application of SCB liquid manure in pear orchard managed by cover crops is desirable to maintain the productivity by improving soil physical properties and potential nutrient recovery.

  • In order to obtain plantlet derived by anthers, the anthers of Lilium asiatic hybrid 'Gran Paradiso' were cultured on Murashige and Skoog's medium supplemented with various combinations of auxin and cytokinin. The most suitable pollen stage of anther culture for the callus induction was 3 days before anthesis at the early to late binucleate stage. Organogenic calli were induced on MS medium supplemented with 5.0 mg/L 2,4-D alone and the combination of 1.0 mg/L 2,4-D and 1.0 mg/L kinetin, however, the combination of NAA and BA was more effective than that of 2,4-D and kinetin on plant regeneration through organogenesis. Shoots were formed from the induced callus on the medium with 0.5 mg/L NAA and 1.0 mg/L BA after 180 days of culture. Multiple shoots with 3-4 leaves, roots, and bulblets were formed on the medium with the combination of 2.0 mg/L NAA and 2.0 mg/L BA after 250 days of culture. The chromosome from root tip of the regenerated plantlet showed the diploid (2n=2x=24). Diploid plants were transferred to the pots and all plants were flowered in two years.

  • Effect of rice bran applied alone or in combination with chemical fertilizer on growth and edible quality of rice was investigated. The experiment consisted of 11 treatments: 3 levels of rice bran (RB) (500, 250 and 100kg $10a^{-1}$), 100 and 50% recommended fertilizer (RF) combined with above-mentioned 3 levels of RB, and 100 and 50% RF only. The rice brans were applied at 10 days before rice transplanting. Results showed that plant height 30 days after transplanting was significantly higher at 100% RF treatment than the RB treatments. However, plant height during heading stage was not significantly different between the 100% RF and the RB treatments. At higher RB treatments, ripened grain decreased, while panicle number and plant height increased. In the case of rice yield, 50% RF + RBtreatments exhibited similar or slightly higher yield than 100% RF. These results suggested that the recommended fertilizer can be reduced by 50% in case of applying RB. In terms of nutritional quality, protein content on rice grain increased at higher RB treatment, while amylose content at 50% RF + RB treatments ($17.3{\sim}17.8%$) decreased compared to that of RF ($17.9{\sim}18.1%$). Results showed significant effects of RB application on rice growth and quality.

  • To examine the possibility of protein recycling of shaving scraps containing chromium generated from manufacturing process of leather, the optimum hydrolysis conditions and the withdrawal methods of low molecular weight protein for using the liquid fertilizer sources by investigation of solubilities of hydrolyzed protein, inorganic nutrients contents and molecular weight distributions of hydrolyzed protein from shaving scraps treated with mixed alkaline inducing agents and mixed alkaline proteolytic enzymes including MgO were investigated. In hydrolysis of shaving scraps treated with mixed alkaline inducing agents, the solubility of shaving scraps were clearly different with 65~85% according to the sorts of the inducing agents, and the degree of hydrolysis was high in the order of NaOH, $Ca(OH)_2$ and KOH. The average molecular weights of withdrawal hydrolyzed protein were 10, 40 and 80 KD treated with NaOH, $Ca(OH)_2$ and KOH, respectively. And the chromium contents was about 15 ppm. In hydrolysis of shaving scraps treated with mixed alkaline proteolytic enzymes, the bility of shaving scraps were high in the order of alcalase, esperase and savinase. In c of treating 0.5% alcalase, the low molecular weight of hydrolyzed protein could be withdrawn. The solubility of the hydrolyzed protein was about 85%, the average molecular weight of the protein was below 1 KD and chrome content of the protein was below 10 ppm.

  • The effect of browning inhibitors on quality properties of fresh-cut strawberries was investigated. Half-cut strawberries were treated with dipping solutions alone and with combinations of 1% ascorbic acid, 1% citric acid, 1% sodium chloride, and 1% magnesium chloride, were packaged with low density polyethylene bags, and were kept for 24 hours at $4^{\circ}C$. The levels of oxygen and carbon dioxide in the packages of the samples treated with the combined solutions were the highest and the lowest, respectively. The loss of L value and flesh firmness of fresh-cut strawberries was retarded by the combined solutions than by the dipping solutions alone. The soluble solids and pH were not affected by the browning inhibitor. These results suggest that mixture of ascorbic acid, citric acid, sodium chloride, magnesium chloride may prevent browning and softening of fresh-cut strawberries.

  • This study was conducted to reduce the using amount of chemical fungicides for the control of red-pepper Phytophthora blight. Effect of combination application of two microbial fungicides and two chemical fungicides for the control of red-pepper Phytophthora blight was examined in vitro, in greenhouse and under field conditions. Each microbial fungicides and chemical fungicides was two-fold diluted and mixed-soil drenched. In the greenhouse pot assay, the mixed application of B. pumilus QST2808 and a mixture of dimethomorph + ethaboxam (De) among four mixed applications of two microbial fungicides (B. pumilus QST2808, P. polymyxa AC-1) and two chemical fungicides showed the highest control effect against Phytophthora blight. Also, control effect of mixed application of B. pumilus QST2808 and De was similar to that of single application of De (dimethomorph + ethaboxam) or Mo (mancozeb + oxadixyl). In the field test, when the microbial fungicides (B. pumilus QST2808, P. polymyxa AC-1) and the chemical fungicide(De) for the control of Phytophthora blight of red pepper were mixed-soil drenched four times at 7~10 day-intervals, the control values were in the range of 78.8% to 82.0%. On the other hand when each of the two chemical fungicides (De, Mo) were soil drenched four times at 7~10 day-intervals, the control value were 65.7% to 85.8%. Consequently, the mixed application of the microbial fungicides and chemical fungicides could be recommended as a control method for reducing the using amount of chemical fungicides.
