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.

식물조직배양기술을 이용하여 인삼 root를 생산하고자, 식물생장조절물질로 유도된 인삼 root를 사용하여 최적액체배양조건을 RSM을 이용하여 조사하였다. 최적액체배양조건을 배지의 pH, sucrose 농도, nitrogen 농도, phosphate 농도의 3 level-4factor의 fractional factorial design에 의하여 조사한 결과, 인삼 root의 생장율은 최저 1.00g에서 최고 2.33g까지 나타났다. 다중회기분석으로 구한 model식을 가지고 등고분석과 3차원분석을 수행한 후 독립변수의 최저 또는 최고수준에서 조속변수가 최대치를 나타내지 않는 배지의 pH와 sucrose농도의 변수에 대하여 model식을 편미분한 결과 인삼 root의 최적액체배양조건은 pH5.6, sucrose 3.8%, nitrogen 50mg/L, phosphate 80.7mg/L로 예측되었다. 이렇게 결정된최적조건값들을 model식에 대입하여 얻은 예상치는 2.36g 이었다.

본 연구에서 현미의 발아에 키토산을 활용함으로써 곰팡이 발생을 억제하고 기능성 생리활성 물질인 GABA의 생성을 증진시킬 수 있음을 확인하였다. 100 ppm 키토산액에서 72시간 발아는 현미파우더 그램당 1,035 nmole의 GABA를 보유하게 되어, 발아되지 않은 현미의 136 nmole, 물침종 발아 현미의 771 nmole, 100 ppm 젖산침종 발아 현미의 728 nmole GABA에 비하여 높은 것으로 조사었다. 발아에 의한 GABA 생성증진과 더불어 알라닌의 생성증진 및 글루탐산, 아스파틱산, 세린의 함량 감소가 뚜렸하였다. 키토산처리에 의한 GABA의 생성 증진은 GABA 생성에 관여하는 글루탐산 탈탄산효소의 활성증진이 기여한 것으로 조사되었다. 키토산액에서의 침종 발아는 물침종 발아나 젖산침종 발아에 비하여 곰팡의 발생빈도를 현저하게 낮추었다. 이들결과를 종합할 때 발아현미 제조시 키토산액을 사용하면 기능성 물질인 GABA 함량이 증진되고 곰팡이등의 잡균의 오염을 줄일 수 있어 양질의 발아현미를 얻을 수 있을 것으로 기대된다.

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.
