  • Allium wakegi Araki was grown at plant spacings of 5, 10, 15, and 20 cm to determine the effect of planting density on the growth and yield. Allium wakegi Araki plants grown at the 5 cm plant spacing had the lowest bulb diameter and bulb weight, while plants at the lowest density (20 cm spacing) had the highest bulb diameter, bulb number, bulb weight and fresh weight. In general, plants grown at narrower spacings produced significantly smaller bulb diameter and bulb weight, but resulted in the highest yields and plants per hectare and lower fresh weights per plant.

  • This study was performed to investigate the growth characteristics and inorganic components of Codonopsis lanceolata regarding regional differences. The plant height of Japanese Codonopsis lanceolata was 373.6 cm, so it's revealed that it has more vigorous growth than Korean won. The flowering time of Korean Codonopsis lanceolata was 2 weeks faster than Japanese one. Total fresh weight of root was 41.0 g and 39.0 g for Korean and Japanese respectively, thus, no significance difference was found. However, regarding fresh weight, Korean one had a more fresh weight (35.4 g) of main root parts, but Japanese one had a more fresh weight (9.6 g) of the lateral root part. Each inorganic component was found more in the aboveground parts, regardless of the region and the content of K was the largest. Regarding the content of macroelements for each part of Codonopsis lanceolata, the content of Na, Mg, P, S, and Ca in Korean Codonopsis lanceolata was found the highest on the leaf, followed by stem and root. In the case of Japanese Codonopsis lanceolata, same result was found on the content of Mg and Ca, however, the highest content of Na and P was found in the stem.

  • The aim of this study was to evaluate the effect of charcoal on germination and early growth of barley sprouts. Five treatments were employed based on different amount and treatment method along with control. Barley seeds were soaked in water for 8 hours. Two types of topping treatment were applied such as, charcoal: 100 g (designated as T1) and charcoal: 200 g (T2). Three kinds of mixing treatment were as follows: barley seeds were mixed with 100g of charcoal (designated as M1), with 200g of charcoal (M2), and with 300g of charcoal(M3). The control did not have any charcoal. In our finding, germination rates were observed 53.3% (control), 26.3%(T1), 36.3%(T2), 67.3%(M1), 81.7%(M2), and 79.7%(M3) at three days after inoculation (DAI). Length of radicle was found at 0.90 cm (control), 0.88 cm (T1), 0.99 cm (T2), 1.03cm (M1), 1.66 cm (M2), and 0.70 cm (M3) in 3 DAI. In addition, sprout length was found 4.5 cm (control), 10.4 cm (T1), 11.9 cm (T2), 5.7 cm (M1), 6.3 cm (M2), and 2.1 cm (M3) in 14 DAI. Fresh weight of sprouts were 0.78g (control), 1.03g (T1), 1.07g (T2), 0.96g (M1), 1.07g (M2), and 0.95g (M3). Among the treatment, topping of seeds on 200g of charcoal (T2) showed longest sprout length and fresh weight. Mixing treatments showed higher germination rates and sprout fresh weight. The results may be attributed to difference in micro-climate conditions (mostly temperature and humidity) in the growth boxes in different treatments.

  • The effect of Milliwrap and Uniwrap attached to the lid on the growth and acclimation of lily growing in vitro was investigated. Milliwrap treatment increased the plant height 1.6 and 1.2 times higher than control in 'Dame Blanche' and '94-36', respectively, plant height of 'Dame Blanche' was 6.1㎝ and '94-36' line was 13.4 ㎝. Two treatments slightly inhibited the fresh weight in 'Dame Blanche', whereas Milliwrap and Uniwrap enhenced the fresh weight more than 30% in '94-36'. Leaf width (1.0 ㎝) of Milliwrap treatment was most wide, which was 2.5 times higher than that of control. In the fresh weight of bulblets, the fresh weight per bulblet of treatment was higher than control in '94-36', but the number of bulblets per scale were few in the treatment to control. In the air composition of culture vessel, ethylene content (0.03 ppm) was low in the Milliwrap treatment compared with the control. CO₂ content of control was higher than treatments as 0.11% and it was about 3 times to air condition of out side. The acclimation ratio of Milliwrap treatment was higher as 85.1% and control was similar with Uniwrap treatment.

  • To develop the production of ginseng root using plant tissue culture technology, submerged culture conditions were optimized by means of the fractional factorial design with 4 factors and 3 levels by a RSM computer program. The ginseng (Panax ginseng C. A. Meyer) roots induced by plant growth regulators were cultured on SH medium and the effects of various pH of medium, sucrose concentration, nitrogen concentration and phosphate concentration on fresh weight of the ginseng root were investigated. The fresh weight of ginseng root increased with a decrease in nitrogen concentration and fresh weight of ginseng root varied from 1.00 to 2.33g under various conditions. The optimum pH of medium and sucrose concentration determined by a partial differentiation of the model equation, nitrogen and phosphate concentration were pH 5.6, sucrose 3.8%, nitrogen 50 mg/L and phosphate 80.7 mg/L, respectively. Under these conditions, the predicted growth of ginseng root was estimated to be 2.36g.

  • To obtain quality germinated brown rices containing high levels of ${\gamma}-amonobutyric\;acid$(GABA), chitosan was appliec during the germination of brown rices. The GABA contents of germinated brown rices (1,035 umole/g fresh weight) with 100 ppm chitosan solution for 72 hr were higher than those of ungerminated brown rices (136 nmole/g fresh weight) and brown rices germinated with water (771 nmole/g fresh weight) or with lactic acid (728 nmole/g fresh weight). In addition to the enhancement of GABA, germination in the chitosan solution increased alanine and decreased glutamic acid, aspartic acid and serine in the brown rices. The activity of glutamate decarboxylase was also enhanced by the treatment of chitosan. Furthermore, the germination with chitosan reduced fungi contamination markedly compared with water germination or lactic acid germination. These results suggest that quality germinated brown rices containing high levels of GABA can be obtained by chitosan application.

  • The effect of varied light intensities on the growth of daughter plants during propagation and after transplant to raised beds were examined in 'Sulhyang' strawberry. To this end, four treatments in controlling solar radiation inside a plastic house were made: 55% retractable shading and 35, 55, and 75% fixed shading. The plastic house was shaded only from 11:00 to 16:00 in June and 10:00 to 16:00 in July to September for the treatment of 55% retractable shading. The mean solar radiation inside the plastic house in the retractable 55% shading treatment was 317 W·m-2 and those in the 35, 55, and 75% fixed shading treatments were 183, 165, and 116 W·m-2, respectively, at 10 o'clock in the morning. The 55% and 75% fixed shading resulted in taller daughter plants with wider leaf areas than 55% retractable shading. The retractable shading also showed higher leaf numbers, crown diameters, root weights, and fresh weights compared to fixed shading treatments. Regarding the inorganic element contents, daughter plants grown under 75% fixed shading had 1.35% total nitrogen content followed by 1.19% in 35% fixed shading, 1.14% in 55% fixed shading, 1.14% in open culture, and 1.10% in 55% fixed shading. After 54 days following the transplant of daughter plants to a raised bed, the fresh weight of the aboveground part was the heaviest in the 55% retractable shading and non-shading treatments. The 75% fixed shading treatment had the lowest fresh weight of the aboveground plant parts. The results of this study could be used for the production of high-quality daughter strawberry plants.

  • This study was conducted to investigate the effect of activated carbon on leave production of Allium tuberosum. Growth characteristics including plant height and leaf length were the highest when activated carbon was added with 5%, suggesting that optimum amount of activated carbon was ranged from 5 to 10%. Weight of fresh green vegetable in Allium tuberosum was low in control. And fresh weight of Allium tuberosum was higher in 5% treatment of activated carbon. However, when the plants were grown in activated carbon of $5{\sim}10%$, fresh yield of green vegetable of Allium tuberosum can be increased by using Activated Carbon. Activated carbon can be utilized as a soil conditioner in agricultural crop areas.

  • The purpose of this study is to develop fresh pasta added with superjami, which had a high C3G (cyanidin-3-glucoside). Making fresh pasta with wheat flour and superjami(0, 10, 20, 30, 40%) was done, followed by the mechanical test(moisture content, color value, weight, volume, texture, tension) and the sensory analysis(attribute difference test, preference test). Results are as follows. Moisture content of fresh pasta and cooked pasta was the highest in SP40, and the scores of cooked pasta was much higher than those of fresh pasta. L, a and b value decreased as the ratio of superjami powder. Hardness, chewiness and tension force decreased, while weight, volume, adhesiveness and tension distance increased as the ratio of superjami powder. Attribute difference test showed that color intensity, superjami flavor, savory flavor, superjami taste, savory taste, graininess and after swallow were intense as superjami powder was added. The preference test showed that SP20 containing 20% of superjami powder was the most preferable in flavor, taste, texture and overall quality. Therefore, this was taken as the optimal superjami powder contents for maximizing the overall quality of fresh pasta.
