From June to October 2012, severe outbreaks of rust disease on Solidago virgaurea var. gigantea were observed in 5 different regions of Ulleung-do, Korea. Typical rust symptoms appeared as yellow spots, uredinia on leaves, and massive urediniospores covering the entire plant. Severely infected plants became discolored and died. On the basis of its morphological and molecular characteristics, the causal agent was identified as Coleosporium asterum. This pathogen has been reported as rust disease on S. virgaurea in the Canada and United States. In Korea, rust disease on S. virgaurea var. gigantea was reported as Uromyces rudbeckia in 1992. To the best of our knowledge, C. asterum is a novel rust pathogen on S. virgaurea var. gigantea in Korea.

울릉미역취는 울릉도 원산이지만 한국에서 채소로 널리 재배된다. 울릉미역취의 녹병균은 2014년에 Coleosporium asterum으로 처음 보고되었다. 최근에 북미 시료를 중심으로 미역취속(Solidago)의 녹병균(Coleosporium)을 연구한 논문을 통하여 앞서 한국에서 보고된 울릉미역취 녹병균은 C. solidaginis에 포함시켜야 한다는 의견이 있었다. 이 의견을 확인하기 위하여 고려대학교 표본실에 보존된 울릉미역취 녹병균 시료 3점을 연구하여 C. solidaginis임을 확인하였다. 일본과 중국에서 보고된 양미역취의 녹병균은 C. asterum이나 C. solidaginis과는 구분되는 잠재종으로 추정된다. 본 연구를 통하여 그 동안 북미와 유럽에서만 알려졌던 C. solidaginis가 아시아에도 존재한다는 사실을 처음으로 보고한다.

울릉미역취의 저장기간 연장을 위한 MAP기술을 개발하기 위하여, 포장재질과 저장온도가 품질 특성에 미치는 영향을 조사하였다. 울릉미역취를 6월경에 수확하여 $30\;{\mu}m$ PP, $30\;{\mu}m$ Antifogging-OPP, $30\;{\mu}m$ LDPE, $18\;{\mu}m$ Macroperforated-HDPE, $60\;{\mu}m$ Nylon/PE, $85\;{\mu}m$ PVC/PE 재질의 필름으로 밀봉포장하고 4, 10, $20^{\circ}C$에서 저장하면서 포장내의 기체 농도와 품질 특성을 분석하였다. 저장온도 $10^{\circ}C$에서 포장 내의 산소 농도를 비교해보면 PP와 A-OPP 포장구는 $9{\sim}10%$, LDPE 포장구는 $12{\sim}16%$, Nylon/PE와 PVC/PE 포장구는 2%를 각각 유지하였다. 포장 내의 이산화탄소 농도는 PP, A-OPP, LDPE 포장구는 5%를, Nylon/PE와 PVC/PE 포장구는 경시적으로 증가함을 보였다. 중량감소는 M-HDPE 포장구에서는 거의 억제되지 않았으나 그외 포장구에서는 강력하게 억제되었고 저장온도가 낮을수록 억제효과는 증가됨을 보였다. 가용성 고형분 함량과 pH는 $4^{\circ}C$와 $10^{\circ}C$에서는 큰 변화를 보이지 않았고 포장재질의 영향도 받지 않았으나 $20^{\circ}C$에서는 포장재질에 따라 다른 변화양상을 나타내었다. 관능적 품질 특성인 외관, 색 및 전반적 기호도가 저온과 PP 포장구에서 가장 높게 평가되었다. 이로써 울릉미역취에 적합한 MAP 조건은 포장 내를 약 10% 산소와 5% 이산화탄소로 유지할 수 있는 PP 재질과 $4^{\circ}C$ 저장인 것으로 확인되었다.

We collected seeds of Solidago virgaurea plants growing at different altitudes on the Mt Hakusan area in Japan and cultivated them in a naturally-lit green house. Three-week-old seedlings were irradiated with supplemental UV-B for 12 h each day for 1 and 2 weeks. After a week of itradiation the seedlings of the population collected from the higher altitude at Oh-nanjiho (ON) had accumulated more anthocyanins than those from the lower altitude at Bettoh-deai (BD). Levels of anthocyanins in the ON seedlings were highly correlated with the dose of UV-B radiation and the correlation was also observed after 2 weeks. The growth of the third leaves was retarded by UV-B radiation in both populations. The extent of growth retardation in the third leaves was correlated with the dose of UV -B radiation in both populations. However, no significant difference in the extent of leaf area growth was observed between the ON and BD populations. The increase in plant fresh weight was extensively inhibited in the ON seedlings after 1 week of UV-B radiation. The inhibition was recovered to those in the BD population by 2 weeks irradiation. These results indicate that these populations respond differentially to supplementary UV -B radiation during the first week. Because flavonoids such as anthocyanins play an important role in protection against UV-B radiation in many plants, populations growing at higher altitude may be better able to adapt to increased global levels of UV-B radiation.

The perennial edible wild plants such as Aster glehnii, Solidago virgaurea subsp. gigantean, Allium ochotense, Athyrium acutipinnulum, Aruncus dioicus var. kamtschaticus and Codonopsis lanceolata have cultivated as the main income crops introduced into the fields about 30 years ago in Ulleung island. Soil samples were collected from 190 fields and assessed the effects of management practices on soil chemical properties at wild edible plant fields under no-till system. The strong acidic soils of pH 5.4 or less were detected in 45% of the soil samples. The level of soil organic matter was being held at mean $63{\pm}28g\;kg^{-1}$, 2.7 times higher than upland soils in Korea. Available phosphate and exchangeable potassium showed more than recommended levels of upland crops as $680{\pm}489mg\;kg^{-1}$ and $1.94{\pm}1.7cmol_c\;kg^{-1}$, respectively. The fields of Solidago and Aster showing strong soil acidity and high level of available phosphate and water soluble $NO_3{^-}$ were distinguished from other crops in analysis of variance and principal component analysis of soil chemicals. These results suggested that high frequency of acidic soil and high levels of available $P_2O_5$, exchangeable $K_2O$ and water soluble $NO_3{^-}$ were accompanied with the use of urea and NPK-fertilizer based on nitrogen in the field. However, further research is needed to understand the appropriate management of fertilization and the prevention of soil acidification for wild edible plants.

Objectives : This study aimed to analyze contents of chlorogenic acid among major ingredients and determine the optimal solvent for the antioxidant activity from Solidago virga-aurea var. gigantea(SV) aerial part. Methods : Mature aerial part of extracted SV at the first crop on June 2018 was used. SV was mixed with each at the ethanol concentrate rates of water, 10, 30, 50, 70, and 100% and extracted them for three times for eight hours at $70^{\circ}C$. The contents of chlorogenic acid and seven kinds of antioxidant activities were measured in SV extracts. Results : The highest the contents of chlorogenic acid was from 10% ethanol extracts showed. Total polyphenol and flavonoids of SV extracts were 126.16 mg/g and 105.84 mg/g, respectively. Scavenging activities of DPPH, ABTS, and hydroxyl radical significantly increased in a dose-dependent in SV extracts, while it was almost similar with control at the concentration of $500{\mu}g/mL$. $Fe^{2+}$ chelating activity significantly increase in a dose-dependent in SV extract, it was lower than control. Nitrite scavenging activity increased, dose-dependent in the sequence of pH 1.2> pH 3.0 > pH 6.0 in SV extracts, while it was almost similar with control at the concentration of $500{\mu}g/mL$, pH 1.2, and pH 3.0. Conclusions : Thus, this study found that higher contents of chlorogenic acid and excellent antioxidant activity were contained in 10% ethanol extracts in mature aerial part of SV. It is expected to be used as basic data as natural antioxidant materials.

The effects of adding goldenrod leaf (GL) and stem powder (GS) (1 and 2%) to sausage meat were evaluated for quality characteristics. The compositional properties, pH, cooking yield, instrumental color, emulsion stability, viscosity, texture, and sensory properties were investigated. Adding GL and GS increased the moisture and ash concentration in sausages. Furthermore, increasing the amount of added GL and GS helped to develop (p<0.05) cooking yield, emulsion stability, and viscosity in the meat batters. Sausages with 2% GL and GS had significantly higher springiness and hardness than those of the control. No significant differences in cohesiveness were observed among the treatments. CIE L*and CIE a*values were highest (p<0.05) in the control sausage. Treatment with 2% GL resulted in the highest CIE b* values (p<0.05) in batter and sausages. No significant difference was observed between the control and other treatments for the overall acceptability. Overall, this study indicated that GL and GS could be used as dietary fiber in sausages to improve quality characteristics.

The effects of adding goldenrod leaf powder (GLP) and goldenrod stem powder (GSP) (0.1% and 0.5%) to raw ground pork on antioxidant activity were examined. The following six treatment groups were used: Control (without antioxidant), GLP1 (with 0.1% GLP), GLP2 (with 0.5% GLP), GSP1 (with 0.1% GSP), GSP2 (with 0.5% GSP) and AS (with 0.05% ascorbic acid). The chemical compositions, pH values, instrumental color, conjugated diene (CD), free fatty acids (FFA) and thiobarbituric acid-reactive substance (TBARS) value were measured during 15 d of storage at chilled temperatures. The addition of GLP and GSP showed no effect on moisture, protein and fat contents of the samples. However, adding 0.5% GSP increased the ash contents of ground pork (p<0.05). The pH values of treated samples decreased until day 7, and then increased thereafter. The addition of GLP and GSP decreased the $L^*$ and $a^*$ values and increased the $b^*$ value (p<0.05). The CD, FFA and TBARS value of the control were higher (p<0.05) than samples containing GLP and GSP. The addition of GLP and GSP resulted in a significant decrease in CD, FFA and TBARS values. Overall, this study demonstrated that GL and GS could be used as an antioxidant of raw ground pork.
