Background: Curcuma longa L., a perennial crop originating from tropical and subtropical region, including India, is noted for its important medicinal properties. However, C. longa plants are unable to endure the winter season in Korea, and its rhizomes were invariably succumb to fungal infection when stored in polyvinyl bags. In this study, we accordingly sought to develop a C. longa variety capable of producing high rhizome yields and to identify stable conditions under which rhizomes can be stored in Korea. Methods and Results: We evaluated the agronomic characteristics of nine C. longa germplasms and examined the effects of storing rhizomes at different temperatures (4℃ to 24℃) in paper bags or plastic baskets. We found that the finger rhizomes was higher in CUR02, CUR03, and CUR06 germplasms than those of other groups. Furthermore, in terms of yield per 1 ㎡, the weights of the finger rhizomes and tuberous roots were significantly higher in CUR09 (3.4 ㎏/㎡) and CUR04 (678.7 g/㎡) than those of other groups. Therefore, we consider that these C. longa germplasms might be useful as breeding material. Although the fresh weights of the rhizomes were slightly reduced when stored in paper bags and a plastic baskets at 10℃ to 15℃, there was no evidence of fungal decomposition or sprouting, which is observed when using a conventional storage method. Conclusions: The results of this study indicate that the selected C. longa germplasms can provide a useful source of breeding material for the development of high yielding varieties and that a temperature ranging from 10℃ to 15℃ and the use of paper bags or plastic baskets provide stable post-harvest storage conditions for C. longa rhizomes.

문제 정의
This study was conducted to determine the optimal conditions for storage of rhizomes during the winter season. Fresh weight loss, decomposition rate attributed to fungi and sprout rate were evaluated according to the storage containers and temperature.
제안 방법
Rhizomes were placed in a paper bag and a plastic basket, respectively. And they were stored at 4℃, 10℃, 15℃, and 24℃ (room temperature, RT hereafter) for 30, 60, and 90 days.
In this study, we evaluated several C. longa genetic resources to determine their agronomic traits and to utilize as a breeding material. Additionally, we evaluated different storage temperatures and containers in an attempt to discover stable rhizome storage methods which do not involve curing.
The test field formed ridges and covered with black plastic bags after the compost was applied using basal fertilization at a total of 4,000 ㎏ per 10 a, considering the soil fertility. The experiment plot was arranged by the randomized complete block design with triplicate. For planting density, furrow spacing was 30 ㎝ in the 90 ㎝ ridges, with 20 ㎝ of plant intervals.
Every 30 days, the loss of fresh weight, the level of fungal contamination, and sprouting rate were recorded. This experiment had a randomized complete block design. Three independent experiments were performed, representing biological replicates.
To develop new Curcuma longa L. varieties with improved yield and quality and adapted to a Korean cultivation environment, growth characteristics including emergence rate for aerial and underground portions of C. longa plants were evaluated.
대상 데이터
1). Investigations were performed from 2015 to 2016 and three independent experiments were performed, representing biological replicates. All data had shown the average of 2 years.
genetic germplasms used for evaluation of growth characteristics comprised a total of 9 germplasms (Table 1). The materials were collected in Korea, China, and Japan and was provided from the National Agrobiodiversity Center (Jeonju, Korea). These were compared with C.
데이터처리
Statistical significance of the results was evaluated using One-way ANOVA for comparisons between multiple groups. All calculations were performed using SPSS software Version 22.
성능/효과
The conventional storage method (in sealed polyvinyl bags at 4℃, sprayed with water every 2 days) was compared as a control. Every 30 days, the loss of fresh weight, the level of fungal contamination, and sprouting rate were recorded. This experiment had a randomized complete block design.
후속연구
In addition, Korean environmental conditions also result in a reduced yield of rhizome. Therefore, to produce a high yield of rhizome with improved quality, further studies of C. longa development are needed.
