        Background : The rhizome of ginger (Zingiber officinale) is widely used as a spice or a traditional medicine. It contains the phenolic compounds, such as gingerol, zingerone and shogaols as the major pungent compound. Ginger is commonly used for various types of "stomach problems," including motion sickness, colic, upset stomach, gas, diarrhea, irritable bowel syndrome (IBS), nausea. The cultivation area of ginger is 1,046 ha, and it is cultivated as 5th of 55 medicinal crops in Korea (2016). When ginger is cultivated in a vinyl house, the growing periods can be prolonged by early sowing and the yield is improved compared to the conventional cultivation. This experiment was carried out to investigated on growth, rhizome shape and yield as affected by the soil covering in rain-shelter greenhouse. Methods and Results : Seed ginger was planted on March 10 at 75 × 15 ㎝ planting density in greenhouse. The soil covering on furrow area was carried out on June 20, July 20 and August 20. The control, conventional cultivation was planted four rows on 120 ㎝ wide ridge. As a results of applying the soil covering, emergence was 2 - 3 days earlier than that of conventional cultivation. On November 5, samples were harvested for each treatment, and growth characteristics, tuber shape, and yield were investigated. As the number of soil-cover increased up to 3-times, the weight of the tuber increased to 44.4% and the length to 21.9% as compared with the control. However, as the number of soil-cover increased, workspace was needed, resulting in fewer seeding gingers and lower total yield. Therefore, it was advantageous to perform two times soil-cover to obtain the maximum yield. In the case of soil cultivation, the length of the foot was longer than that of conventional cultivation, and the quality was improved. Conclusion : From the above results, it is recommended that the soil covering is carried out twice at greenhouse’s cultivation. The first covering is in mid-June, and the second is in mid-July.

        Background: The current regulations regarding the storage of medicinal herbs do not define the storage temperature; instead, but the only requirement is that the plastic bags used for storing the medicinal herbs should be tightly sealed during storage. The practice of storing medicinal herbs at room temperature (28℃), causes many problems, including growth of insect pests on the stored medicinal herbs. Thus, it is necessary to understand the effect of insect pests on the quality of medicinal herbs stored at room temperature (28℃) for the improving the relevant regulations. Methods and Results: Cnidium rhizome and Angelica radix were infested with Lasioderma serricorne F. adults and incubated at 28℃ for 2.5 and 5 months. The population of L. serricorne was established rapidly, and left many holes, cadavers, and feces on the stored medicinal herbs, thereby greatly damaging the product appearance and hygiene. In addition, active ingredients of the medicinal herbs were significantly decreased, probably reducing their medicinal quality as well. Conclusions: These results indicate that the current regulations are not sufficient to prevent the establishment of storage insect pests and guarantee the quality and hygiene of stored medicinal herbs. Therefore, it is necessary to devise proper storage protocols and upgrade the current relevant regulations to maintain the quality of medicinal herbs during storage.

        Background : The practice of keeping the medicinal herbs at room temperature causes many problems, but due to lack of sufficient field research and study, it is difficult to improve related regulations and safety management. Methods and Results : The Cnidium Rhizome and Angelica gigas Root were inoculated with Lasioderma serricorne F. and incubated at 28℃ for 2.5 months and 5 months. After five months, the number of Lasioderma serricorne F. in Cnidium Rhizome increased from 30 to 1,429 (about 47 times). In the same period, the number of insects in Angelica gigas Root increased from 30 to 663 (about 22 times). Due to the rapid increase in pest population, hygiene deteriorated, changes in the active ingredient and appearance quality of the herbal medicines, which greatly damaged the value of the herbal medicine. Conclusions : These results show that current regulation requiring only sealing and not specifying the storage temperature do not guarantee quality safety. Therefore, it is necessary to establish appropriate preservation standards and improve management regulations in order to preserve safety.

        Studies were carried to evaluated the influence of storage method by temperatures and fillers on yield and quality of seed rhizome in turmeric. Seed rhizome was stored at styrofoam box filled with rice hull and sand (3:1) or vermiculite for 30, 60 and 90 days at different temperatures (5, 10 and 15℃. compared to traditional method (rhizome only). Parameters were obtained for weight loss, cold injury, percentage of decayed in stored rhizome during storage periods. Also, the germination, growth pattern and yield from stored rhizome has been investigated. It was confirmed that storage of turmeric in stored with filled with vermiculite helps in prevention of rhizomes from microbial and fungal attack. The storage of rhizomes in styrofoam box without any filler at low temperature below 10℃. is not advocated due to heavy losses weight and decayed in management of postharvest for turmeric rhizome. Germination percentage, growth pattern and yield was maximum for rhizomes stored at styrofoam box filled with vermiculite for 90 days at 15℃. The paper outlines a brief attempt to assess the efficacy of non-chemical methods including optimal storage method (temperature and filler) of control of decay and moisture losses during storage of turmeric.

        본 연구는 백련 연근 저장에 있어서 세척과 절단의 연근 조건과 저장 온도에 따른 품질의 변화를 알아보고자 수행하였다. 저장 후 90일까지의 연근의 질량은 조금씩 감소하였는데, 0℃와 5℃에 비하여 15℃에서 저장한 처리는 질량의 감소가 많았다. 연근의 경도는 저장 온도에 상관없이 저장기간이 지남에 따라 감소하였으나, 전반적으로 0℃에서 저장하였을 때 경도의 변화가 적었다. 색도 L 값은 세척하지 않고 절단된 연근에서 저장온도가 증가할수록 크게 낮아졌고, 갈변현상이 나타났다. 미생물 발생은 저장 온도가 높은 10℃와 15℃ 처리는 저장 40일 후부터 나타나 0℃ 저장에 비해 빨리 발생했으며, 저장 90일 후에 18.2~49.2%의 연근에서 미생물이 발생하여 품질이 크게 떨어졌다. 따라서 백련 연근은 세척한 후 0℃에서 저장하는 것이 장기 저장에 효과적이었다.
