Abstract Barley plants may be severely damaged by aphids,mainly because they may transmit viruses,suck food and disrupt tissues. There are resistant lines and susceptible lines in barley to aphids. The changing amounts of gramine from seeding to mature stages were investigated on 27 lines from 1989 to 1991. Barley was sown aound November 20 in the year and harvested in early June. Higher amount of gramine in seeding stage in all lines were detected,then gradually decreased with barley growth until 2 to 3 weeks before the earing stages. At this time aphids had appeared on the barley leaves and increased in population. The susceptible lines had a tendency of greater decrease in gramine content than the resistant lines at the time of aphid population growth. The maximum aphid population was observed from the end of April to early May. The gramine content was almost constant this time. The degradation mechanisms may be important factors determining the defference of resistant and susceptible lines at the aphid population growth stage. The susceptible lines may have a higher activity of degradation mechanism.

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.
