| Abstract | Twenty-two isolates of Pyrenophora teres Drechs. collected from Japanese and Canadian spring barleys were inoculated to 38 barley varieties having various genetic backgrounds. The analysis of variance for the discase ratings showed that there were significant differences both in the virulence of isolates and the resistance of varieties. However, the interaction among isolates and varieties was not statistically significant. Both Finlay-Wilkinson regression analysis and principal component analysis by Additive Main effects and Multiplicative Interaction effects(AMMI)model classified the isolates into three groups,which were different in origins and sympton types. A spot tyte isolate was distinguished from net type isolates by its generally high virulence. A slight pathogenic differentiation was suggested between Japanese and Canadian net type isolates. |

| Abstract | Plant-feeding arthropods, in the course of evolution have adapted differentially to their plant host and thereby gained access to the available resource. Plants responded by developing chemicals and morphological defense to arthropods. Some secondary metabolic substances in plants have been assumed to be toxic or deter feeding. Aconitic acid in the barnyard-grass subspecies, Echinochloa oryzycola Vasing has been reported to be an active component against brown rice planthopper Nilapalvata lugens (Stal) (Kim et al. 1976). Aphids, Ropalosiphum padi. L., R. maidis (F.), Schizaphis graminum (Rondani)and Sitobion akeviae (Shinji), are important pests of barley (Hordeum vulgare L.) and wheat (Triticum aesstivum L.). On barley plants, more than seven aphids per stem causes yield loss (Hansen 1990). R. maidis sometimes severely infested corn plants (Zea mays L.), the leaves being wet by honeydew. Melanaphis sacchari (Zehntner) caused brownish decay of leaves of a susceptible line・ of sorghum Sorghum bicolor Moench. We examined the relation between aconitic acid contents and aphid densities in wheat, barley, corn, sorghum, barnyard grass and rice (Rustamani et al. 1992a). The plants containing larger amounts of aconitic acid showed a moderate degree of resistance to aphids. The findings obtained on additional lines in 1991, and on other components, such as DIMBOA (2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one), are reported herein. |

| Abstract | The extracellular polysaccharides have been fractionated from the culture medium of carrot(Daucus carota)cell culrures by precipitation with ethanol and by chromatography on DEAE-Sepharose CL-6B DEAE-Trisacryl M ion-exchange and Bio-Gel A-1.5m gel-permeation.The sugar composition and molecular mass of purified neutral and acidic polymers were determined. The neutral and acidic polymers were treated with purified endo-Β-glucanase from Trichoderma viride and pectic depolymerases,such as endo-pectate lyase from Erwinia carotovora Er. and endo-polygalacturonase from Kluyveromyces fragilis, respectively. The "hairly"(ramified)regions of acidic polymer were sequentially treated with purified α-L-arabinofuranosidase and β-galactosidase from carrot cell cultures, and were further hydrolyzed with 50mM trifluoroacetic for 1 hr at 100℃. From these results, the extracellular polysaccharides secreted from carrot cell cultures are charactarized. |

| Abstract | In Japan, wheat is usually cultivated from December to June as a second crop in the same field as rice. In Cd-polluted areas, the fields are affected by both wastewater and the emissions from the chimneys of zinc refineries or plating factories. The application of inhibition agents, such as slaked lime, calcium silicate or fused magnesium are applied to inhibit the absorption of these metals by plants. Many reports have been made on the decrease of metal absorption through the application of some form of calcium, phosphate or silicate. Also, it has been reported that wheat is more sensitive to CdS than to CdO. However, almost all experiments were performed at less than 500 ppm Cd in soil, and these experiments have not been made at a concentration close to the level critical for wheat plants. There have been few reports on the effects of calcium cabonate on metal tolerance or metal uptake at the a level critical wheat. The typical example of using calcium carbonate was investigated by Maeda, and the application of phosphate by Koshino, and by Muramoto et al. The effects of calcium carbonate on the metal content of wheat to the critical levels were examined. |

| Abstract | Major literary works are, as is generally admitted, a mirror in which multiple currents of any particular age are faithfully reflected. Upon reading Goldsmith's The Vicar of Wakefield (hereafter referred to as The Vicar, 1766), one cannot resist an impression that this is especially true of the work. What strikes us is a pervasive atmosphere of harmony between man and nature and a keen sense of poetry to be enjoyed heartily in the characters' daily life. These are reflected in the narration by Primrose the protagonist and Anglican clergyman. True we see in the work signs of an uneasy relationship between the haves and the have-nots due in part to the abuse of power by the former at the sacrifice of the latter; and due in part to the age's legacy of surviving brutality, the miserable condition of life, and the resulting social ills in the lower order of society. Also, we discern in it signs of the incipient decay of the traditional village community. Still, the village life retains its wholeness and integrity in the fabric of a close-knit human network based on its agricultural way of life. |
