A new mungbean cultivar Daseon (Vigna radiata (L.) Wilczek) was derived from the cross between KM9003-2B-783 and Keumseong at the Jeollanamdo Agricultural Research ＆ Extension Services (JARES) in 2006. Daseon has erect growth habit, heart leaflet, greenish purple hypocotyl, black and straight pod when matured, and dull green seed surface. A thousand seed weight was 52 g, sprout yield ratio was 630%, and the anthocyanin (delphinidin 3-glucoside) of fresh sprouts contained 1.7 ug/g. The average plant height was 2 cm shorter than the check cultivar (Owool). It is field resistance to mungbean mottle virus, cercospora leaf spot, and powdery mildew. The average yield was 1.76 ton/ha, which was 21% more than check cultivar.

When kiwifruit root system infected with nematodes was treated by hot water dipping treatment, the maximum temperature for this treatment was suggested as $50^{\circ}C$. The lowest killing temperature of internal root-knot in the root tissue was $48^{\circ}C$. Consequently, root-knot nematodes could be killed without damaging root tissues by the hot water dipping treatment at $48^{\circ}C$ for 10 minutes. This could be useful for organic production and distribution of kiwifruit seedlings by avoiding the synthetic nematicides which are not easily decomposed in soil once applied.

The present studies were carried out for three years from 2007 until 2009 to control nematode and to increase yield of cucumber by crashed-rape seed application at polyethylene film house. Crashed-rape seed has a lot of glucosinolate. Myrosinase decompose gulcosinolate into isothiocyanate and thiocyanate when crashedrape seed go to decay at soil. Those chemical compounds act on poison to nematode at soil. When the crashedrape seed treated at soil, an amount of thiocyanate at soil was risen up. Thiocyanate of plot treated with 200 and 400 kg crashed-rape seed per 10a was 30 and 40 mg/kg, respectively. Nematode(meloidogyne spp) population at soil was 13 to 17 nematodes per dried soil 300g. Yield of cucumber increased 6 to 15 percent to be compared with control. While, Nematode(meloidogyne spp) population of control plot were 463 nematodes per dried soil 300 g. This level was much higher than 150 nematodes which can be brought about injury to plant. Even if the more an amount of crashed-rape seed application, the higher yield of cucumber and control effect of nematode. Consider economical efficiency, 200 kg of crashed-rape seed per 10a was the most effective. Therefore, we suggest applying 200 kg of crashed-rape seed per 10a to control soil nematode when culture cucumber at plastic film house.

Analysis of the various constituents and determination of biological activities in the different parts (root, stem, and leaf) of Allium victorialis var. platyphyllum were carried out. Potassium and calcium were detected in higher contents (mg/100 g fresh wt.) than other minerals. The total phenolic content (mg tannic acid eq./100 g dry wt.) decreased in the order of leaves ($792.7{\pm}16.6$) > stems ($160.3{\pm}6.8$) > roots ($101.5{\pm}2.7$), and the total flavonoid content (mg quercetin eq./100 g dry wt.) was as follows: leaves ($497.9{\pm}11.1$), roots ($35.7{\pm}0.4$), stems ($18.5{\pm}1.4$). DPPH radical-scavenging activity and inhibition activity against the formation of cholesteryl ester hydroperoxide in rat blood plasma was higher in the leaves than in roots and stems. Extracts of A. victorialis separated by parts displayed antimicrobial activity against Clostridium perfringens, Staphylococcus aureus, Listeria monocytogenes, Vibrio vulnificus, Vibrio parahaemolyticus, of which the strongest activity was against C. perfringens.

Background: The purpose of this study was to evaluate methods to reduce seeding expenses, thereby increasing farm income. This study investigated the effects of rain shelter controlled cultivation and adapted seeding times on the stable seed production of Scutellaria baicalensis Georgi. Methods and Results: Seed germination was conducted under 10 condition compose to control, water washing, cold storage at $4^{\circ}C$ for 15 days, seed sterilization with a benomyl pesticides, hormone treated seed by submerging in 100 ppm $GA_3$ with the cold storage at $20^{\circ}C$ and $25^{\circ}C$, darkness in a covered petridish and illuminated with a 1,500 Lux lamp. There were three cultivation type, open cultivation with non-woven fabric mulching, cultivation with a vinyl covering and rain sheltered in a plastic greenhouse. Sowing dates were April 27, May 18, June 7 and June 28, 2013. Plants were spaced 10 cm apart in rows 30 cm apart. Mixed oil cake fertilizer, $N-P_2O_5-K_2O$ (12-10-10) was applied at $600kg{\cdot}10a^{-1}$. Conclusions: Optimum germination occured in darkness at $25^{\circ}C$ and cold storage after submerging in $GA_3$. The highest seed yields ($4.5kg{\cdot}10a^{-1}$) occurred in the plastic greenhouse for the April 25 sowing. The highest root yield (17%) was found on April 1, under greenhouse conditions.

This study was carry out to investigate the effect of supplemental lighting on the growth and flowering of Rosa hybrida 'Nobles' in winter. Supplemental lighting was treated during 5 hours at night with sodium lamp and fluorescent lamp, and cut flowers harvested 2 times for the experimental period. After supplemental lighting, air temperature and slab temperature in glasshouse was higher in sodium lamp treatment than control. Realtive humidity was low in sodium lamp treatment. Total nitrogen phosphate, potassium, calcium, and magnesium contents of stem in sodium lamp treatment were higher compare to the other treatment. In sodium lamp treatment, the potassium and magnesium content of leaf in control were lower than the others. Chlorophyll content was not different by source of lighting. Stem length and diameter was longer in sodium lamp treatment. In two times, the yield was highest in sodium lamp treatment. Therefore, supplemental lighting with sodium lamp in winter season was recommended for improving the yield and quality in cut rose 'Nobles'.

패션프루트(Passiflora edulis)는 브라질이 원산지이며 아열대와 열대지역에서 재배되고 있는 다년생 상록덩굴식물로 시계꽃과(Passifloraceae) 시계꽃속(Passiflora)에 속한다. 전 세계적으로 500여종이 분포하고 그 중 10여종은 식용, 나머지는 관상용으로 이용되고 있다. 지구온난화로 인한 기온상승으로 전남지역 재배에 적합한 대체 아열대과수 개발이 필요하다. 패션프루트는 겨울 최저온도가 $3^{\circ}C$이상 조건에서 재배 가능하여 남부 지역는 무가온 하우스재배를 하고 있지만 시설내 6월 하순부터 8월 중순까지 $35^{\circ}C$ 이상 고온이 지속되어 과실을 볼 수 없다. 8월 하순부터 피는 꽃은 인공수분으로 착과되어 11월부터 수확이 가능하지만 이후에 낮은 온도($10^{\circ}C$이하)로 착색이 진행되지 않아서 동해피해로 수확을 포기해야 한다. 어느 시기까지 인공수분을 해야 당년에 안정적인 수확이 가능한지를 알아보고자 패션프루트의 후기(2차) 개화시기 중에서 8월 30일, 9월 10일, 9월 20일, 9월 30일에 인공수분 하여 11월 하순에 착색이 정상적으로 진행되는 처리를 조사한 결과 8월 30일 처리구만 11월 21일 착색이 되었다. 미착색과에서 내용물이 진노랑색으로 진행되면 후숙하여 상품과로 판매가 가능하기 때문에 진노랑색에 도달한 시기를 조사하였다. 조사에서 9월 10일까지 인공수분 처리한 과실은 후숙하여 상품과로 판매가 가능하였다.

The purpose of this study was to observe the effects of antibacterial activities on various medicinal herbs. Medicinal herbs used this study was Curcuma aromatica, Scutellaria baicalensis, Angelica dahurica, Platycodon grandiflorum, Houttuynia corolata, and Forsythia saxatilis. To evaluation of the antibacterial effect, we used S. gallinarum(ATCC 9184), S. typhimurium(SAL-13, France), S. enteritidis (ATCC 10376), Escherichia coli(E-62, O78), and S. gallinarum(E. coli). Extracts from each medicinal herbs divided into 100mg/ml, 50 mg/ml, 25 mg/ml, and 12.5 mg/ml. Antibacterial activities achieved by the paper disc test. Antibacterial activities was showed at extracts from Scutellaria baicalensis, Houttuynia corolata, Forsythia saxatilis, but little found at Curcuma aromatica, Angelica dahurica, Platycodon grandiflorum.
