This study aimed to evaluate the utilization of the top of a low intake of root, through the analysis of the antioxidant activity of the powder of hydroponic-cultured ginseng. Quality characteristics and antioxidant activity were compared and analyzed with Korea’s traditional dessert Gaeseong-Juak, which is made of the powder of hydroponic-cultured ginseng's leaf by adjusting the added volume. DPPH radical scavenging activity of the hydroponic-cultured ginseng by the part powder was in the following order: highly stem, leaf and root. It was measured as 67.9%, 42.9%, and 25.9% at the 1 mg/m level. Gaeseong-Juak was prepared by adding hydroponic-cultured ginseng leaf powder at 0%, 0.3%, 0.6%, and 0.9% of the rice powder. As the content of hydroponic-cultured ginseng leaf powder increased, moisture content, L-value, and a-value were significantly decreased, while the b-value was significantly increased. The texture profile analysis of Gaeseong-Juak was not significantly different among the samples. In the sensory test, the sample containing 0.6% hydroponic-cultured ginseng leaf powder achieved good scores. The DPPH radical scavenging activity of Gaeseong-Juak was significantly increased, as the addition level increased, compared to the original. Based on the above results, hydroponic-cultured ginseng leaf was verified to be a possible natural antioxidant. It can increase food's nutritional values and possibilities when made of hydroponic-cultured ginseng, using leaf which is added to the traditional dessert Gaeseong-Juak.

재배시기, 시설형태 그리고 시설내 계배위치에 따른 가상환경의 차이와 이에 따른 양액계배 오이의 생장 반응을 알아보기 위하여 여름재배와 억제재배, 1-2W형 하우스와 무기둥 하우스에 양액계배를 통해 오이를 패배한 후 시설내 부위별 기온, 상대습도, 일사량과 생장해석을 통해 얻어진 생리적 형질들을 조사하여 비교한 결과는 다음과 같다. 하우스 내부의 평균기온이나 평균상대습도는 하우스 형태간 유의한 차이가 없었으나 일사량은 1-2W형 하우스가 무기둥 하우스에 비해 유의하게 높았다. 일누적일사량은 1-2W형에서는 남서쪽이 무기둥 하우스에서는 북서쪽이 대체로 높았다. 초장과 엽수는 억제재배보다 여름재배에서 높게 나타났으며 엽면적은 억제재배에서 많았다. 상대생장율은 순동화율 및 엽면적비율과 고도로 유의한 정의 상관관계를 보였으며 상대생장율에 대한 기여도는 순동화율이 엽면적비율보다 높은 것으로 나타났다. 작물생장율은 엽면적지수와 고도로 유의한 정의 상관을 보여 엽면적지수의 증대가 단위면적당 생산량의 증대에 크게 영향하는 것으로 나타났다. 전 생육기간의 일평균기온는 상대생장을 및 순동화율과 고도로 유의한 정의 상관관계가 있었다. 억제재배에서는 전 생육기간의 누적일사량과 상대생장을 및 순동화율과 유의한 정의 상관관계가 있었다. This experiment was conducted to investigate the effects of climatic factors varied due to the type of plastic house, cultural season and location in the house on the growth of cucumber plants grown by nutrient solution. There were two growing periods, summer culture and retarding culture, two types of plastic houses, 1-2W type house and post-less house. Air temperature, relative humidity and amount of solar radiation in the plastic houses were measured. Also, dry weight of leaves and stems, plant height, number of leaves per plant, leaf area per plant and fresh weight of fruits per plant were observed. Plant growth analysis were conducted and interrelationships between climatic factors and physiological characteristics were investigated. The results were as follows. There were no differences between the type of plastic houses in the average air temperature and average relative humidity in the plastic house, but amount of solar radiation in 1-2W type house was significantly higher than that of postless house. Daily cumulative solar radiation were highest in southwest side of 1-2W type house and northwest side of postless house. Plant height and number of leaves per plant were higher in summer culture than retarding culture, while leaf area per plant was higher in retarding culture than summer culture. Relative growth rate (RGR) showed highly significantly positive correlations with net assimilation rate (WAR) and leaf area ratio (LAR). Contribution of NAR to RGR was much higher than that of LAR. Crop growth rate (CGR) showed highly significantly positive correlations with leaf area index (LAI). It appeared that increase of LAI was important to increase productivity of cucumber. Average daily air temperature for the whole growing period showed highly significantly positive correlations with RGR and NAR. Furthermore, cumulative solar radiation for the whole growing period in retarded culture showed significantly positive correlation with RGR and NAR.

This experiment was conducted to investigate the effects of compost leachate and concentrated pig slurry on growth of pepper in substrate hyrdoponic culture. In process of composting, compost leachate was was through a saturated compost heap. Pig slurry was filtered by ultra filtration and concentrated by reverse osmosis process. The pig slurry was mixed with chemical nutrient solution and byproduct based on nitrogen content. Peppers were grown in the seven different hydroponic solutions; compost leachate (CL), concentrated pig slurry (CS), compost leachate + byproduct (CL+BP), concentrated pig slurry + byproduct (CS+BP), compost leachate 50% + nutrient solution 50% (CL+NS), concentrated pig slurry 50% + nutrient solution 50% (CS+NS) and chemical nutrient solution for pepper. The chemical nutrient solution was the standard solution of National Horticulture Research Station for the growth of pepper. The concentration of nutrient solution was adjusted $1.6{\sim}2.0mS/cm$ in EC. The compost leachate and concentrated pig slurry were low in phosphorus (P), calcium (Ca), magnesium (Mg), but rich in potassium (K). Growth characteristics as affected by the different nutrient solution were significantly different. Growth and fruit characteristics treated with CL 50+NS 50%CS and 50+NS 50% were similar with NS 100% control plot. The dry weight of stem and leaf were 107.4, 104.2g in plot of NS 100% and CS 50%+NS 50%, respectively. The fruit of pepper showed lowest in the plot treated with 100% concentrated pig slurry, and the growth of pepper severely decreased after application of 100% CS treatment. The yield of pepper was not significantly different between the plots treated with mixture of CS50 + NS50% and 100% nutrient solution treatment. Fruit yield of the compost leachate concentrated pig slurry plot were 59, 14% compared to control, repectively. In conclusion, the mixture solution of 50% of pig slurry and 50% of nutrient solution could be used as a nutrition solution of pepper in hydroponic culture.

Effects of Boron Applications on Flower Spike Dieback of Statice (Limonium spp.)

Choi, Chang-Hak,Jeong, Dong-Chun,Lee, Jin-Jae,Song, Young-Ju,Ahn, Byung-Koo,Lee, Jin-Ho 한국토양비료학회 2013 한국토양비료학회지 Vol.46 No.3

This study was conducted to investigate the effects of boron treatments on flower spike dieback of Statice (Limonium spp.) grown in soilless hydroponic and soil cultures under rain shelter system. The growth of Statice was gradually improved with increasing boron applications in the hydroponics, but not in soil culture with boron treatment as foliar spray or soil application. The degree of flower spike dieback in 6 levels (0, no dieback incidence to 5, very severe dieback incidence) ranged between 0.5 with boron application and 4.4 with no boron treatment. The content of boron in Statice flower spike increased with increasing rates of boron applications in the hydroponics, but the contents of P, Mg, and N were not affected by the boron application. However, K content was highest with no boron treatment. In soil culture, incidence of flower spike dieback decreased with foliar spray or soil application of boron. Therefore, boron application was effective in reducing flower spike dieback and improving cut-flower productivity and its quality, and the recommended rates of boron application were $50{\sim}80{\mu}gL^{-1}$ for hydroponics culture whereas 0.2% borex or ${\geq}0.4kg\;10a^{-1}$ boric acid by foliar spray application for soil culture.
