    초록

    Many onion growers and researchers assert that differences in soil type, agricultural practices, weather, and duration of prolonged onion cultivation in a particular field could affect onion bulb quality. This study evaluates the bulb quality of onions grown in different regions and determines the correlations between bulb characteristics and postharvest loss during cold and ambient storage. Soil and onion bulbs were collected from fields in six onion growing regions in Korea, during the growing season of 2011-2012. The fresh weight, dry matter content, and carbon (C), sulfur and magnesium contents of the onion bulbs were significantly affected by the location in which they were grown. Bulbs grown in Muan had the greatest number of scales, thinnest scale thickness, and the highest total soluble solids (TSS) and total fiavonoids (TF). Bulbs originating from Jecheon had the lowest pyruvic acid (PA), total phenolics and TF. Storage loss of bulbs from the different regions was similar in refrigerated storage, but differed in ambient temperature storage. Bulb fresh weight was positively correlated with scale thickness (r = 0.617) and cold storage loss (CSL; r = 0.398). Dry matter content was positively correlated with C (r = 0.958) and TF (r = 0.256) contents, while it was negatively correlated with CSL (r = -0.424). CSL was primarily affected by the fresh weight, as well as the dry matter, C, and PA contents of the bulbs, while ambient storage loss was primarily influenced by the amount of TSS.

    초록

    Salinity tolerances varied greatly among potato cultivars. The low correlation between growth and yields of aerial parts under high salinity suggests that, in commercial agriculture, it might be more practical to compare relative yields to controls. Additionally, 'Superior', 'Kroda', 'Romana', and 'Duback' might be very useful cultivars to use in breeding programs to develop salinity-tolerant potatoes, as well as for sustainable potato production in saline areas.

    Kim, Ji Hee , Suh, Jeung Keun , Lee, Ae Kyung
    원예과학기술지 = Korean journal of horticultural science & technology v.34 no.6 ,pp. 830 - 839 , 2016 , 1226-8763 ,

    초록

    Germination of Hemerocallis seeds as influenced by cold stratification at 5 degrees C (CS) and maturity of seeds evaluated using X-ray imaging has not been well investigated. Seeds of H lilioasphodelus, H citrina, H citrina 'April Flower', and H minor collected from China and H thunbergii collected from Korea were germinated at 20 degrees C without pre-temperature treatment, while H. hongdoensis, H. dumortieri, H minor, and H. vespertina seeds were treated with CS. Harvesting 'Stella de Oro' capsules at 35-40 days after anthesis yielded mature seeds with well developed embryo and cotyledons analyzed by X-ray images with a 92% germination in 17 days after sowing. Seeds of H. thunbergii and H. citrina germinated in less than 13 days without CS; two weeks of CS did not accelerate seed germination. Seeds of H. hongdoensis germinated in 24 days when seeds were stored at 25 degrees C without CS and in less than 27 days when cold stratified. Therefore, 'Stella de Oro' capsules should be harvested at 35-40 days after anthesis to harvest mature seeds. Cold stratification is not required to accelerate seed germination in the Hemerocallis taxa evaluated in this study.

    원예과학기술지 = Korean journal of horticultural science & technology v.34 no.6 ,pp. 840 - 844 , 2016 , 1226-8763 ,

    초록

    Quinoa (Chenopodium quinoa Willd.) is a grain crop with high nutritional value. The leaves and sprouts of quinoa can also be consumed either raw or cooked, providing considerably nutritional value as well as high antioxidant and anticancer activities. This study was carried out to obtain basic data to assist in the practical design of a plant factory with artificial lighting for the cultivation of quinoa as a leafy vegetable. We estimated the energy content of the quinoa and the electrical energy required to produce this crop. The yield was 1,000 plants per day, with a planting density and light intensity of 0.015 m(2) (15 x 10 cm) and 200 mu mol.m(-2).s(-1), respectively. The total number of plants, cultivation area, and electricity consumption were estimated to be 25,000, 375 m2, and 93,750 mu mol.s(-1), respectively. White fluorescent lamps were used at a power of 20.4 kW from 1,857 fluorescent lamps (FL, 55 W), and the cost for electricity was approximately 1,820 dollars (exchange rate of $1 = 1,200 won) per month. For a daily harvest of 1,000 plants per day in a closed plant factory, the estimated light installation cost, total installation cost, and total production cost would be 15,473, 46,421, and 55,704 dollars, respectively. The calculated production cost per plant, including labor costs, would be 27 cents for the 25-day cultivation period, with a marketable ratio of 80%. Considering the annual total expenses, income, and depreciation costs, the selling price per plant was estimated to be approximately 56 cents.

  5. [국내논문]   Occurrence of White Rust and Growth of Chrysanthemum 'Baekma' by Control of Relative Humidity with Night Ventilation and Heating in the Greenhouse  

    Yoo, Yong Kweon , Roh, Yong Seung , Nam, Byung Cheol
    원예과학기술지 = Korean journal of horticultural science & technology v.34 no.6 ,pp. 845 - 859 , 2016 , 1226-8763 ,

    초록

    This study was conducted to examine the effect of nighttime ventilation and heating on changes in temperature and humidity, the occurrence of white rust, and growth of standard chrysanthemum (Dendranthema grandiflorum) 'Baekma' in a greenhouse. For the ventilation treatments, the mean nighttime humidity in the control greenhouse, which had a closed side window, was higher (94.5%), but the humidity in the natural and natural+fan ventilation treatments was lower (74.3% and 72.8%, respectively). The rate of occurrence of white rust at 34 days after treatment was 100, 98.3, 75.6, and 43.3% for the control, fan ventilation, natural ventilation, and natural+fan ventilation treatments, respectively. The number of infected leaves and telia were the lowest in the natural+fan ventilation treatment compared with the other treatments. The growth of the chrysanthemum 'Baekma' was significantly suppressed in the control because of the occurrence of white rust and high humidity, while plant height, number of leaves, stem diameter, and fresh weight were the greatest in the natural+fan ventilation treatment. For the heating treatments, the mean nighttime temperature of the control (RH 95% heating), which was heating and held at 95% humidity, was 18.4 degrees C, while the temperature of the heating treatment, which was held at 70% relative humidity (RH 70% heating) was 25.8 degrees C. The rate of occurrence of white rust (34.4%), number of infected leaves (0.9), and telia (1.0) were the lowest in the RH 70% heating treatment compared with the other heating conditions. Also, the RH 70% heating treatment showed the best growth in terms of plant height, stem diameter, number of leaves, and fresh weight. Therefore, the natural+fan ventilation and RH 70% heating treatments were effective for the control of white rust and the growth of standard chrysanthemum 'Baekma' in a greenhouse.

    원예과학기술지 = Korean journal of horticultural science & technology v.34 no.6 ,pp. 860 - 870 , 2016 , 1226-8763 ,

    초록

    Continuous monitoring of environmental parameters provides farmers with useful information, which can improve the quality and productivity of crops grown in greenhouses. The objective of this study was to develop a greenhouse environment measurement system using a low-cost microcontroller with open-source software. Greenhouse environment parameters measured were air temperature, relative humidity, and carbon dioxide (CO2) concentration. The ranges of the temperature, relative humidity, and CO2 concentration were -40 to 120 degrees C, 0 to 100%, and 0 to 10,000 ppm, respectively. A 128 x 64 graphic LCD display was used for real-time monitoring of the greenhouse environments. An Arduino Uno R3 consisted of a USB interface for communicating with a computer, 6 analog inputs, and 14 digital input/output pins. A temperature/relative humidity sensor was connected to digital pins 2 and 3. A CO2 sensor was connected to digital pins 12 and 13. The LCD was connected to digital pin 1 (TX). The sketches were programmed with the Arduino Software (IDE). A measurement system including the Arduino board, sensors, and accessories was developed (totaling $244). Data for the environmental parameters in a venlo-type greenhouse were obtained using this system without any problems. We expect that the low-cost microcontroller using open-source software can be used for monitoring the environments of plastic greenhouses in Korea.

    초록

    Recycling nutrient solutions in closed hydroponic production systems is usually accompanied by an imbalance of nutrient solutions when concentration is controlled according to electrical conductivity (EC) levels. This study investigated whether it was possible to automatically control the concentrations of five essential elements nitrogen (N), phosphorus (P), potassium (K), calcium (Ca) and magnesium (Mg) using only N, K and Ca ion sensors. N, P, K, Ca, and Mg uptake was measured in the nutrient solution, and relationships between absorbed ions were analyzed through twice-repeated experiments in lettuce. Results confirmed that the pattern of PO4 ion uptake was similar that of N, and the pattern of Mg ion uptake was similar that of Ca. PO4 ion uptake was most highly correlated with N, and Mg was most highly correlated with Ca. Regression coefficients of N and PO4 were significantly different at 1.04 and 0.55, respectively, but were similar between Ca and Mg at 0.35 and 0.40, respectively. Additional experiments were conducted to measure nutrient uptake in pak choi and rose plants, both to confirm the results from the first experiment in lettuce, and to assess possible application to other crops. Coefficients of determination both for N and PO4, and Ca and Mg were considerably high (R-2 = 0.86) in cultured pak choi, and similar results were observed in cultured rose (R-2 = 0.87 and 0.73, respectively). Regression coefficients for cultured pak choi were 0.56 and 0.24, respectively, and for rose were 0.51 and 0.16, respectively. Although the results obtained for N and PO4 were not consistent between the lettuce experiments, N and PO4 have similar regression coefficients for all crops. No common coefficient was found between Ca and Mg.

  8. [국내논문]   Growth and Phytochemical Contents of Ice Plant as Affected by Light Quality in a Closed-type Plant Production System  

    Kim, Young Jin , Kim, Hye Min , Hwang, Seung Jae
    원예과학기술지 = Korean journal of horticultural science & technology v.34 no.6 ,pp. 878 - 885 , 2016 , 1226-8763 ,

    초록

    A study was conducted to examine the effects of light quality on the growth and phytochemical contents of ice plant in a closed-type plant production system. Seeds were sown in a 128-cell plug tray using rockwool. The seedlings were then transplanted into a deep floating technique system with recirculating nutrient solution (EC 1.5 dS.m(-1), pH 6.5) in a closed-type plant production system. The nutrient solution was supplied at two weeks after transplanting with 2.0 mM NaCl concentration in all treatments for the development of the bladder cells. The three light sources with different light qualities used were as followed; FL (fluorescent lamps), combined RW LED (red:white = 7:3), and combined RBW LED (red:blue:white = 8:1:1) at 150 mu mol.m(-2).s(-1) PPFD with a photoperiod of 14/10 hours (light/dark). The results showed that the FL treatment had the greatest growth enhancement effects on the leaf area and the fresh and dry weights of the shoots and roots. The SPAD values were significantly higher under the FL and RBW LED treatments, at 29.8 and 30.6, respectively. No significant difference was observed in salinity under all treatments. Chlorophyll fluorescence was significantly higher under the FL treatment. The total phenol content and antioxidant activity were the highest under the RBW LED treatment. The total flavonoid content was significantly higher under the RBW LED and FL treatments. Hence, the results indicate that the growth of ice plant was maximized under the FL treatment. The phytochemical contents were maximized under the RBW LED treatment.

    원예과학기술지 = Korean journal of horticultural science & technology v.34 no.6 ,pp. 886 - 897 , 2016 , 1226-8763 ,

    초록

    The physical properties of rooting media for the establishment of plugs in a greenhouse are modified according to variations in the greenhouse environment throughout the season. In this study, we established a standard for rooting media for the production of plug seedlings for each growing season (summer, winter and spring.fall). Eight types of peatmoss (PM) and 4 types of perlite (PL) commonly used in Korea were collected and blended with the ratio of 7 parts PM to 3 parts PL (v/v) to make 32 different rooting media blends. We determined the total porosity (TP), container capacity (CC), air-filled porosity (AFP), pH, and electrical conductivity (EC) of the 32 media blends, and 6 media blends were selected for seasonal use. We also conducted additional analyses for plant easily available water (EAW), buffering water (BW), cation exchange capacity (CEC), and nutrient contents in the 6 media blends. The TP, CC, and AFP of the 32 media blends ranged from 64.7 to 96.0%, 42.9 to 90.1%, and 1.3 to 27.8%, respectively, indicating that the physical properties were strongly influenced by the type of PM and PL. The pH and EC of the PMs ranged from 2.96 to 3.81 and 0.08 to 0.47 dS.m(-1), respectively. However, after blending the PM with the PL the pH was raised and the EC was lowered The media blends selected for the summer growing season were Blonde Golden peatmoss (BG) + No. 1 perlite size
