본 연구는 진주시 소재 우산고로쇠 인공림에서의 수액 채취 시기별 출수량 및 구성성분을 분석하기 위해 수행되었다. 수액채취는 한 달 간격으로 2회에 걸쳐 이루어졌으며, 각 회당 채취목은 각각 소경목(흉고직경 10~20 cm) 5본씩 이었다. 일평균 기온이 1.16 ± 2.15℃로 조사된 1차 시기(2019년 1월 10일 ~ 2월 09일)의 수액 총 출수일이 약 32일, 총 출수량은 약 60.59 L로 관찰되었다. 일평균 기온이 2.55 ± 1.30℃로 조사된 2차 시기(2019년 2월 12 ~ 22일)에는 총 출수일이 약 11일이었으며 총 출수량은 약 13.38 L로 1차 시기 기준의 약 22%에 해당하는 양으로 감소하였다. 1, 2차 채취 시기별 수액의 당 성분 분석 결과 자당(Sucrose)의 함량이 출수초기 최고 2.5%를 나타냈으며 출수 종료시점에는 최소 0.8% 대로 감소하였다. 포도당(Glucose)과 과당(Fructose)은 Sucrose에 비하여 함량이 낮았으며, 0에 가까운 수치를 나타내었다. 채취 수액의 무기성분 분석 결과, 주요 성분은 칼륨(41.69 ~ 89.75 mg/kg), 칼슘(24.66 ~ 48.14 mg/kg), 마그네슘(10.18 ~ 27.25 mg/kg)이었다. 1, 2차 채취 시기별 수액 간의 sucrose함량 및 무기성분의 함량 범위는 유의적인 차이를 보이지는 않았다. 결과적으로 시기를 달리한 우산고로쇠 수액 채취에 있어서 출수량은 큰 차이를 보였지만 당 및 무기성분 함량의 경우에는 유의적 차이가 나타나지는 않았다.

This study was conducted to analyze the sap flow and composition by tapping date in Acer akamotoanum from an artificial forest in the City of Jinju. The sap was collected from five saplings (diameter at breast height10-20 cm) in two phases with an interval of a month. During phase 1 (January 10, 2019 - February 9, 2019) with daily mean temperature of 1.16±2.15℃, 60.59 liters of sap was collected over 32 days. Phase 2 (February 12, 2019 - February 22, 2019) with daily mean temperature of 2.55±1.30℃ yielded 13.38 liters of sap over 11 days, which was a reduction to 22% of the total sap flow in phase 1. The analysis of sugar composition in the collected sap from phase 1 and 2 showed that sucrose concentration was 2.5% at its highest during the earlier days of collection and decreased to 0.8% at the end. Glucose and fructose concentrations were measured near 0, and were lower than sucrose concentration. The most prominent inorganic elements in the collected sap were potassium (41.69 - 89.75 mg/kg), calcium (24.66 - 48.14 mg/kg) and magnesium (10.18 - 27.25 mg/kg). The contents of sucrose and inorganic components between the samples collected from phase 1 and 2 did not show significant differences. The sap flow amounts of A. okamotoanum from different tapping periods showed a notable variation, but there were no significant differences in the contents of sugar or inorganic elements.

문제 정의
okamotoanum Nakai in Gajwa Experimental Forest in the City of Jinju. The purpose was to investigate inland adaptability and growth conditions of A. okamotoanum Nakai (Yoon et al., 2012). Nine years after the plantation, we confirmed that the diameter at breast heightreached 10 cm, which indicates the fitness for sap collection (Lim et al.
제안 방법
, 2017). In this study, we collected sap by perforating artificially planted A. okamotoanum Nakai in Jinju area in two phases with an interval of 30 days.
The purpose of this study was to investigate the sap flow based on perforation period and to analyze sap composition in effort to utilize the results as a base line data for inland A. okamotoanum Nakai sap research.
However, the perforation period for the optimal sap production varies by region as each region has different average temperature and diurnal temperature variation. The study site of this research has also been monitoring the sap flow and composition each year since 2014 to predict the perforation period for effective production of the appropriate volume of sap. The result to date based on the average annual temperature of the past 30 years in Jinju area of Gyeongsangnam-do Province suggests the critical date for sap tapping to have the daily mean temperature of 3.
대상 데이터
The plantation is 112 m above sea level and is on the northeastern slope of 32 degrees. Each phase used five saplings (diameter at breast height10-20 cm) of A. okamotoanum Nakai planted in 2005 for the sap collection (Table 1).
Up to two perforations are allowed, but we decided on one perforation using 8 mm hose for this study. Phase 1 collection was conducted from January 10, 2019 to February 9, 2019. Upon completion of measuring the collected sap in phase 1, collection for phase 2 followed from February 12, 2019 until February 22, 2019.
The research site for this study is a plantation in Gajwa Experimental Forest, part of National Institute of the Forest Science’s Forest Biomaterials Research Center located in Jinju, Gyeongsangnam-do Province.
성능/효과
After collecting the samples in two phases with an interval of 30 days, we observed significant difference in total sap flow amount between the two phases and confirmed that result is closely connected to diurnal temperature variation and temperature conditions.
Analysis of eight inorganic elements in the sap showed the highest content of calcium, potassium, magnesium and phosphorus in order, and recorded relatively low levels of sodium, aluminium, manganese, iron and zinc. Previous research also reports that calcium and potassium comprise 81% of inorganic elements in saps (Kim et al.
후속연구
Future studies will follow to discover useful and functional ingredients in A. okamotoanum Nakai sap other than sugar and inorganic elements. The results of this study are to be used as base line data for sap resource collection and production.
