| 抄録 | Three species of Cyperaceous weeds, Cyperus iria (12 strains), C. microiria(12 strains) and C. amuricus (6 strains), were collected from different sites of Okayama, Tottori and Tokyo prefectures, and various morphological characters, biomass and seed production were observed on the plants which were cultivated at Kurashiki. The analysis of variance showed a significant difference among the strains in each character. However, the species overlapped with each other in most morphological characters. Prinipal component analysis on the 21 characters showed that 83% of the total variation could be explained by the first three components: the first component (37%) was regarded as factors concerning spikelet and seed production; the second component (28%) was regarded as factors concerned the size of vegetative parts; the third component (18%) was largely affected by seed weight and floret density. Scatter diagram on the first and third principal components showed that the 30 strains of three species divided into three groups, and strains in each group correspond to the three species without exception. Based on the second and third principal components, strains of C. microiria were further divided into three sub-groups according to size of vegetative parts. Using the cluster analysis, 30 strains of these species were divided into four large clusters; the first was composed of C. amuricus strains, the second was of three strains of C. microiria, the third included the remaining strains of C. microiria, and the last cluster was composed of C. iria strains. It may be concluded that C. microiria is composed of two or three ecotypes which are different in morphological and reproductive traits. |

| 抄録 | A total of 162 strains of wild barley, Hordeum spontaneum C. Koch originating from Iran, Iraq, Turkey and Central Asia, were tested for resistance to powdery mildew. Then, the variation of resistance was compared with that of 145 local varieties of cultivated barley (Hordeum vulgare L.) originating from the same region of the wild barley collection. Ten different isolates of the parasite with Japanese origin were separately inoculated onto the first leaves of the host plants. The infection types were classified into the following: i, immunelike; R, highly resistant; M, moderately resistant; and S, highly susceptible. Resistant strains with i, R or M infection type were more frequent among wild barleys as compared with the cultivated forms. It is noteworthy that among these three resistant reactions,the M type was most frequent in the wild barley. To compare the degree of resistance to a total of 10 isolates, the resistance score was calculated in each of the wild and cultivated strains as the following: Scores 1,2,3 and 4 were given to the infection types of i, R, M and S, respectively, and the mean score for 10 isolates was calculated. Wild barley showed significantly low resistance scores as compared with those of cultivated barley. This was also confirmed by the cluster analysis; the cluster with more resistance to 10 isolates consisted of many strains of wild barley. Next, the resistance of wild barley was characterized by their broader effective ranges to different isolates. According to the x2 test for independence of reactions to two different isolates, the resistant factor(s) involved in wild barley was confirmed to be rather non-specific to the parasite. It was concluded that H. spontaneum may be useful genetic resources for the breeding of resistance to powdery mildew as well as local varieties. |

| 抄録 | Orchid fleck virus(OFV) was isolated from Calanthe spp.(Cal. discolor,Cal. Bicolor,Cal. Hizen,Cal. triplicata,Cal longicalcarata,Cal Satusma) showing light-green and/or yellowish fleck mosaic on the leaves, which different from previously known viruses of Calanthe. OFV caused systemic infection in Calanthe, Chenopodium quinoa and Beta vulgasis var. cicla, and local infection in C.amaranticolor, C. murale, Spinacia oleracea, Tetragonia expansa, Nicotiana tabacum, N. clevelandii, N. glutinasa, N. rustica, Vigna unguiculata. C quinoa and T expansa are useful as indecator hosts and as a source of virus for inoculation, diagnosis and purification. Sap from C. quinoa was infective after dilution to 10-3 but not 10-4, after 10 min at 45 but not 50℃, and after 1 hr at 20℃ but not 2 hrs. For sap inoculation, it is best to use the homogenate of OFV-onfected leaves within about 7-8 min after homogenization in summer and within about 15 min in winter. The virus particles were bullet-shape or bacilliform, approximately 45-50×105-125 nm in a negatively stained praparations. In ultrathin sections, the viroplasms were observed in the nuclei, and the virus particles and the chracteristic spokewheel structures were found both in the nuclei and the cytoplasm. Antiserum (precipitin tiner:1/512) against the present virus reacted strongly with the isolates of OFV-Cy-50, similar to that of homologous virus. In agar gel diffusion tests, no spur formation occurred among Cal. 94-16 and OFV-Cy-50. In SDS-polyacrylamide gel electrophoresis, one major band of Mr 55,000, probably viral nucleocapsid-protein, and three minor proteins were detected, similar to those of OFV･So from Cymbidium. |

| 抄録 | To examine the changes in cytocrome c content in submerged rice seedlings after exposure to air, antiserum was prepared against purified cytocrome c from rice bran. Western blottong analysis revealed that cytochrome c was detected 6 h after exposure to air, but not detected in submerged rice seedling. On a fresh weight basis, the same level of cytochrome c as that of the aerobic control was found in the 24-h-air adapted seedlings. judging from the high A408/A280 ratio (4.66),the cytochrome c preparation used as antigen was considered to be well purified. However, the antiserum reacted other several polypeptides. One of them reacted more strongly against the antisermu than cytochrome c and its molecular weight was estimated as 11.9 kDa. The polypeptide increased during air adaptation and the levels found in both submerged seedlings and aerobic control were lower than that in 24-h-air-adapted seedlings. |

| 抄録 | Quantitative changes in mitochondrial cytochromes of submerged rice seedlings after exposure to air were investigated using gaussian deconvolution analysis on absorption spectrum at liquid nitrogen temperature. Differnece spectra were obtained from subtracting the absorption spectra of oxidized mitochondria from reduced mitochondria by succinate with antimycin-A. they showed three kinds of b-type cytochrome and a spectral component similar to cytochrome c1. Subtraction of the cytochrome c1-like component from the spectrum by curve analysis showed that three cytochrome bs had similar absorption maximum and that on a mitochondrial protein basis they were constant during air-adaptation. Cytochrome c per mitochontorial protein in submerged seedlings was about half of that in aerobic seedlings and increased by 1.5-fold during air-adaptation. The change in cytochrome c content was in paralleled with that of cytochrome aa3. These findings revealed that there were two groups of cytochromes in the response to air-adaptation,i.e.,three cytochrome bs were constant and cytochoromes c and aa3 increased in parallel. |

| 抄録 | Wall bound α-glucosidase (EC 3.2.1.20) has been solubilized from suspension-cultured sugar-beet cells with Sumyzyme C and Pectolyase Y-23 and purified by a procedure including fractionation with ammonium sulfate, Sephacry S-200 HR column chromatography, and CM-cellulose colum chromatography. The enzyme readily hydrolyzed maltose, nigerose, malto-oligosaccharides, and soluble starch, but hydrolyzde isomaotose more slowly. The enzyme hydrolyzed malto-oligosaccharides and soluble starch at a faster rate than maltose. The wall-bound α-glucosidase from sugar-beet cells is different from the enzymes extracted from the cells and seeds in substrate spesificity. |

| 抄録 | Odontoglossum ringspot virus (ORSV)はJensen＆Gold（1951）によってOdontoglossum grandeにえそ輪紋を生じた病原ウイルスに命名されたが、CattleyaやCymbidiumを中心として広くラン科植物に発生していることが認められている。また、わが国では井上（1966、1983）がCymbidiumからORSVを分離し報告しており、日本でも多種属のラン科植物にORSVの発生が非常に多いことが認められている。シュンラン、カンラン、スルガランなどを含む東洋ラン・Cymbidium属では、かつて葉にモザイク斑を生じた斑紋を”金砂”と呼び非常に珍重されていたが、井上（1984、1990）はこの斑紋がORSVの感染によって生じたものであることを記載した。さらに、井上・呂（1983）は台湾においてもORSVが東洋ランに発生していることを報告している。これらの報告にはウイルスの診断と病徴の記載にとどまり、その病原ウイルスの諸性質についての詳細な記述がなされていなかった。本報告では、葉に軽いモザイク症状を示す東洋ランと呼ばれているスルガラン（Cymbidium ensifolium：蕙蘭）およびカンラン（Cymb. kanran）から検出されたウイルスについて病原学的研究を行ったところ、ORSVと同定されたので、これらの諸性質についての研究結果を報告するとともに、この東洋ラン分離株と既報の洋ランから分離されているORSVおよび同グループのtobacco mosaic virus （TMV）との比較研究を行ったので、それらの結果についても報告する。 |

| 抄録 | 筆者が作成した「社会性確立」と「自我確立」を見る質問紙「自我同一性尺度(IPS)」と、それを中国語に翻訳した質問紙（IPS-C)を用いて、日本と中国の大学生について自我同一性のあり方について比較をおこなった。両国のデータを因子分析した結果、第1軸が「自我確立」、第2軸が「社会性確立」とみなせる、ほぼ同じような因子構造が確認できた。クラスター分析した結果、日本のデータは「責任感」「社会指向」「自立」「自己信頼」のクラスターに、中国のデータは「社会性確立」「自力指向」「自己信頼」に分かれた。両国の平均点を比較した結果、「社会性確立」では中国の大学生のほうが有意に高かったが、「自我確立」では両者に有意差は見られなかった。 |

| 抄録 | Some people may resort to foul language like swearing and cursing to vent uncontrollably intense feelings. These profane and stigmatized expressions, which occur in a large variety of forms, have evolved for centuries and are now deep-rooted in English-sy>eaking countries. It is true that most of them have lost their original or literal senses and are used merely as meaningless expletives, but there are some which are still deemed strictly as taboo--social restrictions prohibit their use in public. This article deals with oaths, imprecations and other blasphemous formulas found in Goldsmith's She Stoops to Conquer (1773) and Sheridan's The Rivals (1775). Examples are sorted according to their fundamental meanings, with some statistical analyses added in a later section for further discussion. We are concerned here particularly with the linguistic features influenced by such social factors as "gender" and "class," tracing the trends in 18th century British society. We hope to elucidate what conventional formulas were widely adopted in those days and how new modes were devised by each author. |
