  • 2001년 9월 경기도 성남시 분화용 브룬펠지아에서 F. oxysporum에 의한 줄기마름병이 발생하였다. 처음에는 생육이 부진하고 아래 잎부터 누렇게 변색되며, 줄기가 마르고 심한 경우 나무 전체가 말라죽는다. 병든 식물체의 줄기를 잘라보면 줄기 내부의 도관부가 갈색 내지 암갈색으로 변하는 것이 특징이었다. 병원균을 분리하여 형태적·배양적 특징을 조사한 결과 F. oxysporum으로 동정되었으며 병원성 검정 결과 자연상태와 동일한 병징을 확인할 수 있었으므로 이 병을 Fusarium oxysporum에 의한 브룬펠지아 줄기마름병으로 명명할 것을 제안한다.

  • Two unrecorded alien plants, Melilotus officinalis (L.) Lam. and M. indicus (L.) All. (Leguminosae) were found in Korea. M. officinalis is native to Eurasia and widely distributed in agricultural regions throughout the world. M. indicus is native to Mediterranean and Southwestern Europe, and naturalized in temperate regions all over the world. These species are morphologically similar to M. suaveolens (Jeon-dong-ssa-ri). However, M. officinalis is distinguished from M. suaveolens by transverse nerved legumes, definite ovary stalks, and five to eight number of ovules in ovary. M. indicus is also distinguished from M. suaveolens by smaller size of flowers, broadly triangular calyx teeth, globose legumes, and minutely papillose seeds. The local name of M. officinalis and M. indicus were given as "Ju-reum-jeon-dong-ssa-ri" and "Jom-jeon-dong-ssa-ri" based on transverse nerved legumes and overall smaller size than M. suaveolens, respectively. The descriptions on morphological characters and photographs at the habitat of M. officinalis and M. indicus are provided.

  • Capsicum annuum belongs to the Solanaceae family, crops of which are extensively cultivated worldwide. It is a food source containing various nutrients and vitamins and also serves as a medicine for treating ailments. The burning feeling experienced while consuming Capsicum fruits is due to the presence of capsaicinoids, particularly capsaicin and dihydrocapsaicin. This study aimed to assess the content of these two compounds in 34 varieties of capsicum and paprika. High-performance liquid chromatography with a gradient elution system and a reverse-phase YMC Pack-Pro column with UV detection at 280 nm was employed. The results revealed that, among the 34 samples, only six samples (samples 1, 15, 20, 29, 32, and 34) contained capsaicin and dihydrocapsaicin, and their highest contents were found in sample 1 - variety name: Sungil-c (capsaicin: 3.42 mg/g extract, dihydrocapsaicin: 1.20 mg/g extract). These findings suggest that the content of these two compounds is attributed to the variety and is influenced by geographical location and environmental factors. Additionally, this study provides a basis for establishing a C. annuum variety with high capsaicin and dihydrocapsaicin contents.

  • A new Gomchwi cultivar 'Sammany' was developed by a cross between Gomchwi (Ligularia fischeri (Ledeb.) Turcz.) and Handaeri-gomchwi (Ligularia fischeri var. spiciformis Nakai). Gomchwi is a common Korean name referring wild edible plant species within Ligularia genus. 'Sammany' has purple colored petiole ears and petiole trichome is absent. It has 2nd degree leaf vein density. Plant height, leaf length, leaf width and petiole length were 46.2, 19.1, 19.5 and 32.1 cm, respectively. Plant height was higher than 'Gondalbi'. Bolting occurred in mid. July and it flowered from late August to early September. 'Gondalbi' bolted and flowered 26 days earlier than 'Sammany', and consequently has earlier flowering time more than 26 day. Leaf number of 'Sammany' was 156 per plant but 'Gondalbi' had 130. 'Sammany' had thicker leaves (0.61 mm) compared to 'Gondalbi' (0.46 mm). As a result, yield was higher in 'Sammany (1,077 g/plant)' than 'Gondalbi (798 g/plant)' and leaf hardness was lower in 'Sammany ($20.8kg/cm^2$)' compared to 'Gondalbi ($23.0kg/cm^2$)'. In addition, 'Sammany' was found to be moderately resistant to powdery mildew. With enhanced agronomic and pathology traits, 'Sammany' was newly registered as a new Gomchwi cultivar (variety protection no. 131 on May 2017).

  • 제주도 서귀포시에서 발견된 Oldenlandia brachypoda DC.를 한반도 미기록종으로 확인하여 보고하고자 한다. 본 종은 속 내의 근연종인 백운풀(Oldenlandia diffusa)에 비해 소화경은 짧고, 돌기가 없으며, 엽액에서 1-3개의 꽃이 피고, 수술대는 0.5-0.8 mm로 길며, 악편은 삼각형, 성숙시 열매의 상부는 팽창하지 않는 점에서 구분된다. 국명은 자생지가 제주도인 점을 고려하여 '제주백운풀'로 명명하였으며, 주요 형질에 대한 도해와 기재, 검색표를 제시하였다.

  • PIPS (Plant Information Processing System)은 발전소 입력신호를 이용하여 운전원에게 체계적인 정보를 제공하여 발전소를 안전하고 효율적으로 운전하도록 지원하는 발전소 감시 및 운전원 지원 시스템이다. UNIX 운영체제 및 workstation 상에 설계된 PIPS는 실시간 처리를 위한 kernel로 RTAP/Plus를 사용하였으며, SL-GMS를 이용하여 GUI (Graphical User Interface)를 개발하였다. 본 논문에서는 계층적 구조를 갖는 데이타베이스 관리 시스템을 이용하여 개발된 PIPS 데이타베이스의 특성 및 구조에 관하여 설명한다. 또한, point name을 이용하여 계층적 구조를 구축하는 소프트웨어를 개발하여 울진 3&4호기 설계 자료로부터 데이타베이스를 구축하였다. 이 시스템은 HP 715/100 workstation과 HP-UX 9.05 운영체제 개발환경에서 개발되었다.

  • Triadenum breviflorum (Wallich ex Dyer) Y. Kimura in Nakai & Honda (Hypericaceae), previously known only in northeast India, China and Taiwan, was found in a few wetlands of Jeju Island in 2008. Additionally, some images online of T. breviflorum suggest that it exists in other places on the Korean peninsula but that it has been misidentified as Triadenum japonicum. This species is distinguished from the latter by white petals, inflorescence from nodes 6-11, linear to narrowly elliptic leaves, and an attenuated base. The local name Huin-kkot-mul-go-chu-na-mul implies a white flower rather than the flesh-pink color of T. japonicum. The morphological characteristics of the species are provided with photographs of the habitat.

  • Enzymes involved in catecholamine synthesis are present in the highest concentration in the adrenal medulla, however they were found also in other, mainly nervous tissues. Increased transcription of genes for catecholamine biosynthetic enzymes is an important mechanism to increase the capacity for epineprine/norepinephrine biosynthesis with stress. Gastrodia elata(Chinese name: Tienma), are very important Chinese herbal medicines used for the medical treatment of headaches, migraine, dizziness, epilepsy, rheumatism, neuralgia, paralysis and other neuralgic and nervous disorders. Immobilize stressed rat markedly increased tyrosine hydroxylase (TH) mRNA and dopamine-${\beta}$-hydroxylase (DBH) mRNA transcriptior level more than control group. But treated Gastrodia elata extracts in immobilized stressed rat slightly increased TH mRNA and DBH mRNA transcription level more than normal group. In addition, we are obtained identical results in PC12 cell line. Decrease of transcription level of TH mRNA and DBH mRNA is indicating that Gastrodia elata have a anti-stress effects which decrease the transcription level of TH and DBH mRNA on catecholamine biosynthesis pathway.

  • A causal agent of bacterial soft rot occurring in soybean sprout cultivation in Korea was isolated and identified, and its incidence in several sprout-soybean cultivars was examined. Infected soybean seeds became light brown and whitish, and could not germinate until 3 days after seeding, accompanying rotting of soybean seeds and sprouts. The causal organism isolated from the rotten seeds and sprouts was identified as Erwinia carotovora subsp. carotovora on the basis of its pathogenicity, morphological and physiological characteristics and the results of the Biolog GN microplate test program. The bacterial soft rot by E. c. subsp. carotovora was firstly described in soybean sprout in Korea, and we name it“the bacterial soft rot of soybean sprout”. The disease occurred more frequently in Nam-hae and Fu-reun sprout-soybean cultivars than in Eun-ha, So-baek, and Ik-san cultivars.
