The Shine Muscat grape(Vitis vinifera L.) have high quality and the cultivation area is increasing recentely in Republic of Korea. The total cultivation area of the country('18) is 963ha, and the cultivation area of Gyeongbuk area is 81%, which is 780ha. But the research on pests causing damage in cultivation is insufficient. Recently, the damage caused by Bark beetles is increasing due to the abnormal weather and the increase of the cultivation area of shine muskets. The Bark beetles that occur in the Grape Shine Muskete plantation are Xyleborinus saxesen, which pierce tree trunks and cause the whole tree to die. Xyleborinus saxesen occurred continuously from April to August, and it occurs in Shine Muscat stem damaged by the frostbite. Shine muskets are weak to frostbite, so it is necessary to keep the trees free from frostbite in winter and early spring.

Vitis amurensis, Aralia cordata, and Glycyrrhizae radix have been widely used in Korea, China, and Japan because of their anti-oxidative and anti-inflammatory activities. The present study investigated the anti-nociceptive and antiinflammatory properties of an ethanol extract (SSB) of a mixture of three medicinal plants of Vitis amurensis (stem and leaf), Aralia cordata (stem and leaf), and Glycyrrhizae radix. Anti-nociceptive activity was determined using chemical (acetic acid and formalin) and thermal (hot plate) stimuli-induced algesia tests. Formalin-induced paw edema was evaluated for anti-inflammatory activity. SSB (25–100 mg/kg, p.o.) and ibuprofen (100 mg/kg, p.o.), a positive nonsteroidal anti-inflammatory drug (NSAID), significantly inhibited the acetic acid-induced writhing response caused by peripherally mediated algesia, but failed to protect thermal nociception in the hot plate test that was employed for centrally mediated analgesic activity. However, morphine (5 mg/kg, s.c.) used as a positive opioid control alleviated the acetic acid-induced writhing response and thermal nociception in the hot plate test. In the formalin test, SSB (50 and 100 mg/kg, p.o.) inhibited the second phase response (peripheral inflammatory algesia), but not the first phase response (central algesia), whereas morphine inhibited both phases of the pain response. Both SSB (25-100 mg/kg, p.o.) and ibuprofen (200 mg/kg) caused significant reduction of the formalin-induced increase of paw thickness, which was the index of inflammation. These results suggest that SSB has a significant anti-nociceptive activity that seems to be peripheral, but not central. SSB also displays antiinflammatory activity in an acute inflammatory model. The present study supports a possible use of SSB to treat pain and inflammation.

This study was carried out to evaluate the basic characteristics of red wine processed from ‘Cheongsan (Vitis amurensis)’ grape cultivar. In order to compare the quality of ‘Cheongsan’ red wine, ‘Campbell Early’ and ‘Muscat Bailey A, MBA’ red wines were also utilized for this study. The pH of the red wines produced from ‘Cheongsan’, ‘Campbell Early’ and ‘MBA’ were 3.1, 3.6 and 4.0, respectively. Tannin, polyphenol, and anthocyanin contents of the ‘Cheongsan’ red wine were 2,939 mg/L, 1,516.2 mg/ L, and 1,882.4 mg/L, respectively. These values were about twice those of ‘Campbell Early’ and ‘MBA’ red wines. The antioxidant level of ‘Cheongsan’ red wine was found to be 5,413.9 mg/L, which was also two times higher than 'Campbell Early' and 'MBA' red wines. Although the acidity of ‘Cheongsan’ red wine is relatively high, ‘Cheongsan’ red wine contains a lot of tannin, matures over an extended period of time and has excellent antioxidant properties. These results indicated that 'Chengsan' grape could be an excellent source for production of high quality red wine.

Vitis amurensis, Aralia cordata, and Glycyrrhizae radix have been widely used as oriental medicinal plants in Korea, China and Japan and found to possess anti-oxidative and anti-inflammatory activities. A previous study demonstrated a protection of an ethanol extract (SSB) of a mixture of three medicinal plants of Vitis amurensis, Aralia cordata, and Glycyrrhizae radix against β amyloid protein-induced memory impairment. The current study was conducted to investigate the neuroprotective effect of SSB against ischemiainduced brain injury. Transient focal cerebral ischemia was induced by 2 hr middle cerebral artery occlusion followed by 24 hr reperfusion (MCAO/reperfusion) in rats. Oral administration of SSB (5, 10 and 25 mg/kg) 30 min before and 1 h after MCAO, and 1 h after reperfusion reduced MCAO/ reperfusion-induced brain infarct and edema formation. SSB also inhibited development of behavioral disabilities in MCAO/reperfusion-treated rats. Exposure of cultured cortical neurons to 500 μM glutamate for 12 hr resulted in neuronal cell death. SSB (1-10 μg/mL) inhibited glutamateinduced neuronal death, elevation of intracellular calcium concentration ([Ca2+]i), and generation of reactive oxygen species (ROS). These results suggest that the neuroprotective effect of SSB against ischemia-induced brain damage might be associated with its anti-excitotoxic activity and that SSB may have a therapeutic role for prevention of neurodegeneration in stroke.

Calepitrimerus vitis (Nalepa) is a grapevine pest and distributed worldwide. This study was conducted to identify grapevine damage related to density of C. vitis and to suggest an effective control time. The damaged flower buds displayed retarded growth and became dried up, and symptoms of damaged leaves such as malformed and bronzed leaves were observed. Flower cluster and leaves were collected and density of the grape rust mite were observed by using a washing and sieving method. The highest mean density (±SE) of C. vitis was found to be 672.6±112.9 per flower cluster with mid-level damage, and 450.1±66.5 per 2 leaves was found on the damaged leaves. These severe damage symptoms were observed in the early spring, and the density of the grape rust mite was significantly higher as 80 times in damaged vineyard than in the undamaged at the early growth stages of the grapevine. To determine the emergence time of the grape rust mite from lower part of a winter bud the ratio of density of C. vitis on upper-bud to lower-bud was observed. On 13 April 2015, 80% of the grape rust mites were observed on upper-bud where the mite could feed at the bud burst stage. Therefore, once the symptoms of damaged flower clusters and leaves are observed, acaricides should be sprayed before inflorescence emergence, and at the early growth stage between bud burst and leaf development in following year. This would allow the decrease of the density of C. vitis in early spring, and the progression of severe damage could be prevented.

본시험은 포도 캠벨얼리의 광폭 비가림 설치 효과를 평가하기 위해 실시되었다. 광폭비가림은 비가림의 폭이 기존의 표준 비가림보다 30 cm 넓게 구성되어 있다. 비가림처리는 모두 대기온도보다 2~3oC 높게 나타났고 광 폭비가림하에서 일 평균온도는 0.5~1oC 정도표준 비가림 보다 높게 나타났다. 상대습도는 대기습도보다 15~20% 낮게 나타났으며 연차간 차이를 보였다. Pseudocecospora vitis 에 의해 발생하는 포도 갈색무늬병의 발생은 2012 년에는 광폭비가림이 표준비가림 보다 55.6% 적게 나타 났고 2013년에는 17.2% 적게 나타났다. 포도는 2년에 걸쳐 수확하였고 당함량, 산함량, 과립중, 과립크기 등 과실품질을 측정하였다. 그 결과 2012년에는 처리간 차이가 명확하지 않았으나 2013년에는 광폭비가림이 당함량이 0.4o Bx 높았고 산함량은 0.8% 낮은 결과를 나타내었다. 이는 광폭 비가림의 적용이 갈색무늬병의 발생 정도를 낮추고, 과실품질에 영향을 미치는 것을 시사한다.

개량머루의 시기별 생육 특성을 구명하기 위하여 액아 발달, 과실 품질, 과실 조직의 해부학적 발달과정을 관찰하였다. 액아는 신초 발생부터 낙엽기까지 가지에서 마디 위치에 관계없이 괴사가 전혀 발생하지 않아 모두 충실하였다. 성숙기 과실 특성은 과립중 1.2g, 과립수 98 개 및 과방중 128.8g이었고, 당도 16.9oBrix, 적정산도 1.57%이었다. 당의 조성은 과당과 포도당이었고 성숙기의 과당과 포도당의 비는 1:1에 도달하였다. 사과산이 유기산 중에서 가장 많았으며 시기별 적정 산도의 변화가 일치하였다. 당과 산은 변색 1주전부터 급격하게 변화하였다. 배주의 퇴화는 수정 전후에 모두 발견되었고 성숙기의 과피는 1층의 epidermis와 7~10층의 hypodermis로 구성되었다.

포도녹응애는(Calepitrimerus vitis (Nalepa) (Acari: Eriophyidae)) 포도를 재배 하는 미국의 북서부, 유럽, 남아프리카 등에서 잎 말림 현상 및 잎과 가지의 생육지 연을 유발하여 문제시되는 해충으로 알려져 있다. 국내에서는 2011년 경기도 화성 시에서 처음으로 발생이 보고되었으나, 발생 소장 및 분포에 대한 정밀한 조사는 이 루어진 바 없다. 따라서 본 연구에서는 경기도 화성시 서신면 2지역(Site1, Site2)과 송산면 1지역(Site3)에 위치한 시설 포도원에서 포도녹응애의 월동 여부 및 분포 조사를 실시하였다. 농가의 면적을 5구획으로 나누고, 각 구획에서 6개의 가지를 무작위로 채집하였다. 가지에서 겨울눈을 절단한 후 실체현미경을 통해 월동 여부 를 확인하였으며, 개체수 계수를 위해‘washing and sieving’방법을 이용하였다. 그 결과 Site1, Site2 두 농가에서 포도녹응애가 발견되었으며, 겨울눈의 껍질 밑에 무 리 지어 있는 것을 관찰하였다. ‘washing and sieving’ 분석 결과 Site1 포도원에서 평균 7871±635(No. of individuals/6 winter buds)개체로 다른 발생 농가에 비해 상 대적으로 높은 밀도를 나타내었다. 또한 주지로부터 눈의 거리와 포도녹응애의 밀 도는 비례하는 경향성을 보였다(y=1311.3x + 3659.3, R2= 0.6931). 이 해충은 이른 봄에 활동을 시작하여 생육 초기에 피해를 입히는 것으로 알려져 있으므로, 월동시 기 발생소장 조사를 통해 포도녹응애의 봄철 초기 발생을 예측하고 피해를 방제하 는데 있어 유용한 정보를 제공할 수 있을 것으로 생각된다.

국내야생종인 새머루로부터 내병성 포도품종 육성에 필요한 육종소재와 유용정보를 획득하고자, 포도 새눈무늬병균과 줄기혹병균에 감염된 새머루에서 식물 방어관련유전자의 발현양상을 분석하였다. Thaumatin (TLP), glutathione peroxidase (GPX), glutathione-S-transferase (GST), chalcone synthesis (CHS), protein kinase regulator (14-3-3) 및 β-glucanase (Glu) 등의 방어관련유전자, leucine reach-repeat (LRR)와 lipoxygenase (LOX) 등의 신호전달관련유전자, polygalacturonase-inhibiting protein (PGIP)과 같은 세포벽관련 유전자의 발현이 포도 새눈무늬병균 접종에 의해 유도되었다. 포도새눈무늬병균의 포자접종 및 배양여액처리에 의해 WRKYtranscription factor 10 (WRKY), fatty acid elongase (FAE)의 발현이 유도되었으며 proline-rich protein (PRP) 유전자의발현은 억제되었다. 발현이 증가한 15개 유전자 중에서 LRR, LOX, TLP, GST 등은 포도새눈무늬병균 포자현탁액 접종에 의해 발현이 크게 증가하였으나, CHS와 tonoplast intrinsicprotein (TIP)는 배양여액처리에 의해 증가하였다. 포도 줄기혹병균의 접종에 의해 LRR, CLP, LOX, TLP, GPX, 14-3-3,GST, PGIP, FAE, TIP, Glu, WRKY 등은 발현이 증가하였고, CHS와 PRPs는 발현이 억제되었다. 포도 줄기혹병균 접종에 의해 활성산소의 축적 및 분해와 관련된 GPX와 GST는 발현이 크게 증가하였다.

Until now, seven species, Acosmeryx nega, Herpetogramma luctuosalis, Ostrinia furnacalis, Endoclyta excrescens, Spodoptera litura, Paranthrene regalis, and Nippoptilia vitis, have been known as lepidopteran grape pests in Korea (Woo, 1980; Lee, 1981; Kim, 1991; NIAST, 2002; Korea grape community, 2009). We discovered thirteen additional species belonging to eight families from Gwangwon and Chungbuk provinces, Korea. Additionally, we corrected the previous records of Deuterocopus albipunctatus and Nppoptilia vitis. They were identified by adult external or genitalic characters first, and also confirmed by the COI marker, compared with two public databases, NCBI and BOLD.

머루(Vitis coignetiae)는 국내에 자생하는 야생종 포도의 한 종류로서, 포도 새눈무늬병에 저항성이다. 내병성 포도 육종에 활용할 유용한 육종소재를 개발하고자 머루의 잎과 과실로부터 cDNA libraray를 제작하였다. 머루의 cDNA library의 총 5,760개의 EST 클론을 분석하여 676개의 contig와 2,306개의 singleton을 분리하여 총 2,982개의 unigene을 분리하였다. NCBI 데이터베이스의 BLAST를 통한 상동성을 검색한 결과, 2,241개의 클론이 기능이 알려진 유전자이었고, 그 중에서 1,442개는 생물학적인 대사에 관여하고 836개는 세포구성물과 관련이 있었다. EST와 contig의 평균 크기는 각각 702bp와 757bp이었다. 포도새눈무늬병균에 감염된 머루 cDNA library로부터 Proline-rich cell wall protein, thaumatin-like protein, class IV chitinase, and pathogenesis-related (PR) protein 10 등의 다양한 방어관련 유전자와 광합성관련유전자 및 수분스트레스 저항성 관련유전자가 많이 검출되었다. 본 연구를 통해 얻어진 머루의 EST 자료는 포도의 새로운 유전자원에 관한 연구 및 내병성 포도 신품종 육종 프로그램에 기본자료로 유용하게 활용될 것이다.

The study investigated the effects of trans-ε-viniferin on in vitro maturation (IVM) and gene expression. Three experiments were conducted. Firstly the trans-ε-viniferin was purified from the leaves and stems of the Vitis amurensis , a common wild grape found in Korea, Japan, and China. In the first experiment, a total of 594 cumulus oocytes complexes (COCs) were used for the evaluation of the nuclear maturation. COCs were matured with various concentrations of trans-ε-viniferin (0, 0.1, 0.5, 1.0 and 5.0 μM). After IVM 42 44 h, the nuclear maturation was evaluated. In the second experiment, a total of 300 matured oocytes were used to examine the effects of different trans-ε-viniferin concentrations (0, 0.5 and 5.0 μM) on porcine oocyte intracellular GSH and ROS levels. In the third experiment, the gene expression of oocytes matured with trans-ε-viniferin (0.5 μM) and the untreated group were evaluated after IVM. As results, we observed that trans-ε- viniferin treatment during IVM did not improve the nuclear maturation. But significantly increased (p<0.05) intracellular GSH levels in 0.5 μM group (0 μM vs. 0.5 μM; 14.6 vs. 16.8 pmol/oocyte) and reduced ROS levels (0 μM vs. 0.5 μM and 50 μM; 174.6 vs. 25.7 and 23.8 pixel/oocyte). The trans-ε-viniferin treatment during IVM of recipient oocytes promoted higher (p<0.05) expression of Dnmt1 mRNA in 0.5 μM treatment group than in the control group. But, the other gene expressions (PCNA, OCT4, caspase3, BAK, BAX and sit1) did not significantly differ from the control. In conclusion, these results indicated that the trans-ε-viniferin treatment during porcine IVM increased the cytoplasmic maturation through increasing the intracellular GSH synthesis, reducing ROS levels and increasing the Dnmt1 gene expression.

본 연구에서는 포도의 저장성을 향상시킬 수 있는 방법을 모색하기 위하여 'Sheridan'과 'Muscat Bailey A' 품종을 전해산성수 가습처리와 오존수 살균처리 및 전해산성수 살균처리하여 0±1℃에서 90±2%의 상대습도에서 60일간 저장하면서 포도의 품질 특성을 조사하였다. 모든 처리구에서 대조구에 비하여 저장성이 향상된 것을 알 수 있었으며, 중량감모율, 비정상과 발생률, 탈립율, 당도 및 진균수 억제 효과는 처리구별로 무처리구에 비하여 전해산성수 가습처리하여 포도를 저장하였을 때 중량감모율이 가장 적게 변화하여 좋은 효율을 나타내었고, 오존수 살균처리 및 전해산성수 살균처리 방법에서 비정상과 발생률, 탈립율, 당도 및 진균수에 대한 억제 효율을 나타내었는데, 오존수 살균방법보다 전해산성수 살균방법에서 높은 효과를 나타났다. 유리당과 총산 함량은 저장기간의 증가에 따라 약간의 감소를 보였으며, 과피의 anthocyanin 함량도 약간 증가하였다. 본 실험결과 전해산성수 가습방법과 살균방법이 우수한 효과를 나타냄을 확인할 수 있었다.

지온이 포도의 생육에 미치는 영향을 조사하기 위하여 노지용으로 많이 재배되는 캠벨얼리와 시설포도인 블랙올림피아를 공시하여 지온을 10℃, 15℃, 20℃, 25℃로 조절하여 재배하고 생육조사와 더불어 광합성 속도 및 식물체의 무기성분함량을 조사한 결과를 요약하면 다음과 같다. 지온 20~25℃에서 품종에 관계없이 엽중, 경중, 근중을 비롯한 모든 생육이 좋았다. 광합성 속도와 엽록소 함량은 20℃구에서 가장좋았다. 지온이 높아질수록 줄기와 뿌리인 인산, 칼륨, 석회의 함량이 많았다.

In this study, phenotypic distribution of 15 major fruit quality traits were analyzed using 252 progenies derived from a cross between ‘Tano Red’ (seed) and ‘Ruby Seedless’ (seedless), to obtain basic data for improving the breeding efficiency of grapevine cultivars. Berry skin color was dark red-violet in 46.4% of the progenies, which is the color of ‘Tano Red’ and ‘Ruby Seedless’, and berry shape was elliptic in 48.4%. Most of the progenies were very juicy with soft flesh, and closely related to the characteristics of ‘Tano Red’. Seeds were well developed in 67.1% of the progenies, rudimentary in 30.1%, and 2.8% were seedless, with seed weight being less than 0.15 g in 84.9% of the progenies. Among the 15 fruit quality traits assessed, bunch density, ease of berry detachment from pedicel, berry weight, berry seed number, berry longitudinal diameter, berry transverse diameter, berry soluble solids, and berry acidity showed normal distributions. Heritability of berry weight, berry longitudinal diameter, berry transverse diameter, berry soluble solids, and berry acidity was 0.89, 0.82, 0.78, 0.86, and 0.93, respectively. Berry weight was positively correlated with seed weight (r = 0.486**), presence of seeds (r = 0.483**), and seed number (r = 0.211**). Seed weight significantly increased with presence of seeds (r = 0.607**) and seed number (r = 0.725**). In addition, presence of seeds was positively correlated with seed number (r = 0.319**). These results could be useful for the identification of quantitative trait loci associated with fruit quality to assist in grapevine breeding.
