Auricularia polytricha has strong decomposition ability on wood fiber and a wide range of temperature adaptation as mid-high temperature mushroom. In addition, Auricularia polytricha does not require light in the mycelial growth period, but it is cultivated in the field because the light promotes the differentiation of fruiting bodies and affects the pigment formation. This study was conducted to investigate the possibility of the cultivation of Auricularia polytricha (Mont.) Sacc. "Geoni" which was bred at Jeonnam Agricultural Research Institute in 2012 at a simple-typed PE film mushroom house, and to compare the quality characteristics of the Auricularia polytricha (Mont.) Sacc. "Geoni" cultivated at air-conditioned mushroom house. Auricularia polytricha (Mont.) Sacc. "Geoni" was cultivated with sawdust-based media (0.9 kg) every 3 days from June 15 to July 13 at air-conditioned mushroom house and PE film mushroom house, and harvested until July 26th. The temperature and the humidity of the air-conditioned mushroom house was maintained at 23°C and 90-9 %. The Irrigation was conducted 1 time per day and 2 to 3 times per day at air-conditioned mushroom house and PE film mushroom house respectively. The harvesting period were the same for each treatment. The fruiting body was 6.0 ㎝ and 5.1 ㎝ in major axis and 4.6 ㎝ and 4.0 ㎝ in minor axis at PE film mushroom house and air-conditioned mushroom house respectively, as a result the size of the fruiting body grown at PE film mushroom house tended to be larger. The thickness of fruiting body was 0.85㎜ and 1.24㎜ at PE film mushroom house and air-conditioned mushroom house respectively. These results are considered to be due to the difference in the humidity control conditions between each treatment. The number of fruiting bodies per bag was 4.3 at PE film mushroom house and more tendency than 3.7 at air-conditioned mushroom house. The springiness of the fruiting body was 1.23 ± 0.21 and 1.01 ± 0.17. the chewiness was 620 ± 89 and 507 ± 128, and the resilience was 0.49 ± 0.03 and 0.35 ± 0.07 at PE film mushroom house and air-conditioned mushroom house respectively. As a whole, it was judged that the physical properties of the fruiting body grown at PE film mushroom house were excellent. Also, when comparing the chromaticity of fruiting body, L(lightness)-a(red color)-b(yellow color) value was 30-5.5-3.9 and 39-6.5-7.5 at PE film mushroom house and air-conditioned mushroom house respectively. The yields did not show differentiated tendency by cultivation time. However, the weight of fruiting body per bag was 308g and 252g at PE film mushroom house and air-conditioned mushroom house respectively. Therefore, according to these result, Auricularia polytricha (Mont.) Sacc. "Geoni" was judged to be a suitable cultivar at PE film mushroom house for summer.

A. auricular-judae cultivars, ‘Yong-a’ was cultivated in JARES on 2015. Ear mushroom have been consumed the form of dried mushrooms imported from china, but the production and consumption of domestic ear mushroom have been increasing recently. However, how the different drying methods affect the quality of domestic varieties is not clear. Therefore, we examined the effects of drying methods to improve the competitiveness of dried ear mushrooms using domestic cultivar, ‘Yong-a’. Ear mushroom samples were dried using sun-drying and hot air drying(50, 60°C) and combined of two methods(hot air drying at 50, 60°C after 3,6 and 9 hours sun drying) and drying time, rehydration ratio, color and hardness, vitamin D2 contents were evaluated. Drying time was the fastest at 60°C hot air drying(11.5h) and the slowest at 50°C hot air drying(16h) and drying time was shorter as the sun drying time was longer. The rehydration ratio was the highest at 60°C hot air drying(18.6%) and increased as the drying time decreased. After drying and rehydration, the color showed no significant difference between drying methods. The hardness of rehydrated mushroom was highest at sun drying and 60°C hot air drying. The contents of ergosterol were not significantly different by drying methods. However, vitamin D2 was lowest at 50 °C and 60°C hot air drying (4.22mg%, 3.87mg%) and highest at sun drying and 50°C hot air drying after 6 hours sun drying (12.52mg%, 12.99mg%). vitamin D2 contents was higher at 50°C hot air drying than 60°C. According to the results of color, hardness, vitamin D2 contents of dried ear mushroom, sun drying is the best method. When the sun drying is not possible, hot air drying at 60°C is suitable, but it is better to use sun drying method to increase the vitamin D2 contents.

Geoni, a new variety of Auricularia polytricha, was bred in JARES(Jeollanamdo Agricultural Research and Extension Services) in 2012. Geoni was selected through the monospore hybridization with JNM21008 and JNM21014 in 2010. Based on a performance test conducted from 2011 to 2012, the Geoni was selected from a line showing an excellent light brown pileus and strong pest resistance. Geoni has a favorable chewiness, light brown and smooth pileus. In addition, Geoni was rich in dietary fiber. MCM(mushroom complete medium), Malt and PDA(Potato Dextrose Agar) mediums were suitable for cultivating the Geoni. The number of effective stipes was 39 ea/0.9 kg and minor axis and major axis of pileus were 6.9 cm and 8.7 cm respectively. The yield of Geoni was 291 g/0.9 kg in plastic bag. Geoni was required 40~54 days for culture at 20oC and 24days for the primordia and growth period, which is longer than that of the control(Pung-un). Somatic incompatibility was formed between parental strains and Geoni. Analysis of the genetic diversity of the new variety "Geoni”revealed a different profile from the parental strains when RAPD(random Amplified Polymorphic DNA) primers were used.

A mungbean variety ‘Suhyeon’ (Vigna radiata (L.) Wilczek) was derived from the cross between ‘Jeonnam14’ and ‘IT208777’ at the Jeollanamdo Agricultural Research and Extension Services (JARES) in 2010. ‘Suhyeon’ has erect growth habit, heart leaflet, green hypocotyl, black and straight pod when matured, and dull green seed surface. The stem length of ‘Suhyeon’ was 66 ㎝, which was 5 ㎝ less than check variety ‘Owool’. The pods number per plant of ‘Suhyeon’ was 24, which was 5 more than check variety. The sprout yield ratio of ‘Suhyeon’ was 8.67 times, which was 16% more than check variety. The contents of starch, protein and fatty acid of seed were 62.7, 27.3, 1.89%, respectively. The average yield of ‘Suhyeon’ was 1.74 ton/㏊, which increased 8% more than that of check variety. (Variety registration number: 5107)

Plant regeneration via organogenesis and somatic embryogenesis was investigated in Korean soybean cultivars including Cheongja 3, Jinpumkong 2, Taekwangkong and Uram. Cotyledon, cotyledon+hypocotyl and hypocotyl segments of 7-day-old seedlings were cultured on MS medium containing various concentration (0, 1, 2 and 4 ㎎/L) of BA and TDZ. The results showed that MS medium supplemented with BA 2.0 ㎎/L yielded the highest shoot formation ratio of 83.3%. In 4 cultivars, Taekwangkong showed the highest ratio of shoot formation. When various sizes of immature cotyledons (S: 1∼ 2 ㎜, M: 3∼5 ㎜, L: 6∼8 ㎜) were tested on MS medium containing 2,4-D 40 ㎎/L for somatic embryogenesis, the optimum size for embryogenic callus induction was 3∼5 ㎜ in length of immature cotyledons. In 4 cultivars, Taekwangkong showed the highest percentage of embryogenic callus induction. The results indicate that Taekwangkong is the best soybean cultivar for plant regeneration via organogenesis and embryogenic callus induction among the 4 cultivars.

대다수의 흙막이 공사 계측현장에서 적용하고 있는 절대치 관리방법은 관리기준치와 계측결과를 절대 비교함으로서 공사현장의 안전성을 평가하는 기법이다. 따라서, 안전성 평가의 판단기준이 되는 관리기준치는 평가결과에 직접적으로 영향을 미치게 된다. 즉 아무리 최 적의 계측시스템이 적용된 현장이라고 하더라도 관리기준치가 타당하지 않으면, 공사현장의 안전성을 정확히 판단할 수 없으므로 관리기준치 의 선정은 매우 중요하다. 그러나 실질적으로 현장 기술자 등은 기존 절대치관리기준치에 대한 신뢰성이 매우 낮으며 관리기준치의 수정보완 의 필요성을 인식하고 있다. 이에 본 연구에서는 계측관리기준치의 수정보완 필요성에 대한 조사결과를 바탕으로 하여 흙막이 구조물의 거동 중 가장 기본이 되며 중요한 흙막이 벽체의 변위에 대한 계측결과를 토대로 확률론적 이론에 의해 관리기준치를 보다 적절하게 설정하여 적용 하는 연구를 수행하였다. 본 연구에서는 계측관리기법 중 시공 전에 설정된 관리기준치와 시공 시 측정된 설측치를 비교 검토하여 그 시점에서 공사의 안전성을 확인하는 방법인 절대치관리방법을 적용하여 관리기준치를 수정하였다.

This study was performed to investigate the adequate standard pot and number of plants per tree of raising seeding pot on the foxtail millet transplanting culture in the southern province. Due to the various application of wellbeinghealth food recently, for upbringing of the foxtail millet, millet and sorghum in minor cereals, R & D and policy support is being promoted actively. The foxtail millet growing season is so short from 90 to 130 days, and it is large variations for a growth temperature. The main results are as follows. When it comes to foxtail millet transplantation, seedling quality of 406 holes, 200 holes and 162 holes of raising seeding pot type were not all significant, and field rooting percentage is accounted for all 94 to 95%. Yield of a foxtail millet was exposed in 406holes 305 kg/10a>162holes 303 kg> 200holes 302 kg order, and it was no significance between test processing. When it's the raising seeding transplanting culture, in case of pot culture, 406holes pot culture were reduced the bed soil cost 63%, pot 50%, working hours 18% for 200holes pot. Transplanting seedling quality per a foxtail millet transplanting culture method, dry weight was high inclination as transplanting number of plant is less, and field rooting percentage displayed more than all 95%. Yield appeared to 2 plants seedling transplanting 315kg/10a> 3 plants seedling transplanting 304kg>1 plant seedling transplanting 256kg order. The projected cost per the pot-sort on the raising seeding transplanting culture of foxtail millet, the seedling transplanting culture of 406holes was reduced 40% percentages compared to 200holes as 76,230won/10a. As a result, 406holes pot and 2plants seedling transplanting culture, labor-saving culture was possible.

The purpose of this study was to establish the optimal growth temperature and to select genetic resources for production of cowpea sprouts. Seowon was treated between 15°C and 30°C at intervals of 3°C to investigate growth temperature. Twelve resources, including Seowon, IT154149, IT154153, Tvu7426, and Tvu7778, were used for cultivating sprouts at a temperature of 27°C. The yield ratio of cowpea sprouts was highest at 27°C (657%), and was reduced when growth temperature was decreased. The hard seed rate was lower when the growth temperature was increased. Vitamin C content was highest at 24°C (2.85 mg/g), ranged between 2.15 and 2.29 mg/g at other growth temperatures, and increased with the length of the growth period. The inorganic component content of cowpea sprouts did not vary based on growth temperature, while the amino acid content increased with increasing growth temperature between 15°C and 24°C, and then subsequently decreased as growth temperature rose from 24°C to 30°C. IT154153 had the highest yield ratio of cowpea sprouts per genetic resource (647%), followed by Seowon (615%), and Tvu7426 (608%). Genetic resources with a higher yield ratio had smaller seeds, a thinner seed coat, and superior germinability. The inorganic components found at highest concentrations in the cowpea sprouts were potassium, magnesium, calcium, sodium, iron, molybdenum, and zinc (in that order). In comparison to raw seeds, the protein, calcium, zinc, molybdenum, and iron content in the cowpea sprouts was higher, while the content of aluminum and boron was lower.

The purpose of this study was to establish the proper sowing time and planting density of cowpeas for labor-saving cultivation. Experiments were carried out in Naju, Jeonnam Province (Latitude 35° 04' N, Longitude 126° 54' E) during 2012 and 2013. The intermediate-erect type strains used in this study were Jeonnam1 and Jeonnam2. Sowing was performed five times between June 25 and August 5 at approximately 10-day intervals in order to establish proper sowing time, and sowed at 5,000, 10,000, 15,000, and 20,000 plants per 10a to establish proper planting density. The days from sowing to first flowering was shortest (32 days) in plants sowed on July 25 and became longer for plants sowed on or around July 25. The days from sowing to first flowering was longest (41 days) in plants sowed on June 25. The days from first flowering to first maturing was shortest (8 days) in plants sowed on June 25 and, became considerably longer at later sowing dates. The days from first maturing to first harvesting ranged from 8 to 10 days, with little difference among the sowing periods. Plants sowed on August 5 harvested at the same time, and plants sowed between June 25 and July 25 were harvested either three or two times. The yield was highest in plants sowed on July 25: 209 kg/10a was harvested for Jeonnam1 and 221 kg/10a for Jeonnam2. Furthermore, harvested at the same time enabled when the harvesting was delayed for around 15 days because the share of the seeds first harvested was highest (91%). The proper planting density was estimated to be 15,000 plants/10a, showing the highest yields of 199 kg/10a for Jeonnam1 and 224 kg/10a for Jeonnam2.
