This study was to acquire data of growth characteristic and aluminum contents by pH regulated nutrient solution in cut hydrangea(Hydrangea macorphylla) ‘Adria’. Stem length of cutting flower surveyed 44.1cm at treatment of pH 5.5, and 40.8cm at pH 4.0, 36.2cm at pH 7.0. Flesh weight investigated 147.2g/stem at pH 4.0, 154.2g/stem at pH 5.5, 122.3g/stem at pH 7.0. Aluminum contents was higher treatment of pH 4.0 and pH 7.0 then treatment pH 5.5. Aluminum contests of the upper part was lower then the lower part of hydrangea stem. So we obtained good quality of cut hydrangea at treatment of pH 5.5. We thought very slow transfer of aluminum in the hydrangea stem.

Five species of cucurbits from major cultivation areas in Jeollanam-do and Jeollabuk-do have been investigated from May to October 2013 in order to create D/B on the occurrence and distribution of Meloidogyne spp. occurring in greenhouse-grown crops according to region (cid:57267) crop, and in order to utilize it as data for pest control, such as the selection of cultivar resistant to Meloidogyne spp., and rotation crop. According to the results of investigation, 50% of cucumber, 31.3% of melon, 26.7% of watermelon, 30% of squash and 18.2% of melon were infected. In cucumber, there was the most severe damage of Meloidogyne spp. in Gimje region, Jeollabuk-do, and the larval density was an average of 1,999 per 100 (cid:62594)(cid:71) soil unit. According to the results of species identification using PCR, the investigation showed that 2 species of Meloidogyne spp. were identified, and they were arranged in the following order of larval density: M. incognita (cid:59577) M. arenaria.
2013年5月至10月，对全罗南道和全罗北道主要栽培地区的5种瓜类进行了调查，目的是根据区域作物(cid:57267)，建立温室作物中丝瓜病发生和分布的D/B，并将其作为选育抗丝瓜病品种和轮作作物等害虫防治的数据。调查结果显示，黄瓜50%、甜瓜31.3%、西瓜26.7%、西葫芦30%、甜瓜18.2%发生侵染。在全罗北道金济地区，黄瓜中被害最严重，幼虫密度平均为1999只/ 100 (cid:62594)(cid:71)土壤单位。根据PCR鉴定结果，共鉴定出2种Meloidogyne sp .，按幼虫密度排列顺序为:M. incognita (cid:59577) M. arenaria;

This study has been made in order to examine the physical control effect against fungus gnat ( Bradysia agrestis Sasakawa; Diptera: Sciaridae) by using a yellow sticky trap and material with which substrate was covered in hydroponic squash in Gwangyang, Jeonnam from March to October 2014. With regard to the control method, the substrate was covered with a black and white film, and a part in which a seedling would be planted was cut out. And if a customized yellow sticky trap was inserted so that the substrate in the cut-out part was not exposed after planting the seedling, the invasion of an adult could be prevented, and no larva appeared in the substrate for the whole growing period. It took 8 hours per 10a to cover the substrate and to install the yellow stick trap. On the other hand, in case of not being covered, it took 88 hours to make an effort at chemical control for the growing period. In case of being covered with black and white film, the number of fruits per plant was larger by 7 in comparison with not being covered. The temperature inside rhizosphere was lower by approximately 1 (cid:59282) , and diurnal variation was small. Thus, the temperature was stable. It was possible to apply this method if mulching was performed at the same time in growing in soil as well as hydroponic crops such as paprika, cucumber, and strawberry.

This study has been made for the seasonal occurrence of major insect pests which occurred in greenhouse-grown hydrangea and the selection of pesticide from March 2013 to December 2014. Major insect pests included Tea red spider mite (Tetranychus kanzawai Kishida), Garden thrips (Frankliniella intonsa), and Melon aphid (Aphis gossypii glover). And among them, insect pests requiring being controlled were T. kanzawai, and F. intonsa. With regard to seasonal occurrence, T. kanzawai occurred in mid-March, and showed the peak period of occurrence in early June, and then showed that it tended to rapidly decrease. F. intonsa started to occur from early April, and its peak period of occurrence was late-June. With regard to the selection of pesticide, in case of T. kanzawai, 4 types such as abamectin emulsifiable concentrate showed a high control value of 93% or above, and in case of F. intonsa, 2 types such as acetamiprid wettable powder too. No pesticides with which hydrangea was treated had phytotoxicity. On the other hand, with regard to the sticky trap's level of attracting F. intonsa according to color, blue has well attracted F. intonsa until late July, while yellow has attracted a lot from August. Accordingly, only if color was made to be different according to the period, forecast and trap effect were high. White had remarkable weak attraction in comparison with other colors.

A new standard rose cultivar ‘Red Ball’ was bred from the cross between light red standard cultivar ‘Red Sandra’ and red standard cultivar ‘Tiamo’ at the Jeollanamdo Agricultural Research and Extention Services (JARES). The cross was made in 2004 and seedlings were produced. After the evaluation of specific characters from 2007 to 2009, it was finally selected and named as ‘Red Ball’ that has standard flower type with light red color (RHS Color Chart Red Group 46A). The major characteristics of this cultivar were as follows : this cultivar produced 128.8 stems/m 2 /year, and it showed 68.4cm in length of cut flower, 9.3cm in flower diameter, 49.8 in petal number, and 9.9 days in vase life. This cultivar can be propagated by both cutting and grafting. The consumer’s preference of this cultivar is relatively higher than that of control cultivar, ‘Tiamo’.

Garden rose popularity has been increased in Korea. However, the commercial demand has not reached out the development of domestic cultivar, and mainly imported cultivars are dominating the domestic market. In this work, mutant garden rose has been developed by using (cid:534) -ray irradiation. Rose ‘Love’ and ‘Rosanna’ cultivars were irradiated till 70Gy of (cid:534) -ray irradiation, and mutated into the form of flower color and shape. For three years, mutants for flower color and shape were selected and isolated into individual plantlets. Rose ‘Love’ with red flower color allowed five outstanding mutants focusing on various flower color and petal number. Rose ‘Rosanna’ also produced five excellent mutants with various flower color, shape, size and petal number.

The cultivation area of genetically modified (GM) crops is increasing worldwide reaching 175.3 million hectares by 2013. Currently in Korea cultivation of GM crops is not allowed and they are being imported for food and forage use only. According to the Cartagena Protocol of Biosafety and The Act on Transboundary Movements of Living Modified Organisms,etc in Korea, the risk assessment for the newly developed or imported GM crops and confined field trials are being conducted throughout the nation. This study was carried out to monitor the safety management of 8 different confined field trials in Jeolla, Chungcheong, Gyeongsang, and Jeju provinces in 2014 and 2015. For each field, separation of district, management of field facility and cultivation, and management records are monitored. Safety management to prevent the unintentional gene flow by seeds and pollen disperse were well performed. However, as some drainage was blocked or running towards the outside of the confined field, precaution to prevent the unintentional gene flow by the soil runoff needs to be reinforced. In the future, based on the biological characteristics of GM crops, more studies on the confined field trial plan, the monitoring period and frequency are required.
