| 抄録 | 本研究では、算数科における習熟度別少人数指導について、児童の自己効力感及び学業成績という2つの特性に着目して検討することを目的とした。児童に対する事前調査・事後調査を実施し、学力面と認知面に対する児童の変容を分析し、習熟度別少人数指導の結果について測定した。T検定を実施した結果、5％の有意水準で有意差があり、児童の学力及び自己効力感が肯定的に変容したことが示唆され自己効力感を高める習熟度別少人数指導の有効性が示された。 |

| 抄録 | The rates of photosynthesis and transpiration were measured in barley and wheat under various environmental conditions, with an open system porometer. The rates of photosynthesis and transpiration in the horizontal leaf and vertical leaf had different diurnal variations. The rate of photosynthesis in the vertical leaf was highest in the morning and in the afternoon, while that in the horizontal leaf was highest before noon. The rates of photosynthesis and transpiration and chlorophyll contents were measured for two species(c.v SARI and Akanmugi) of barley grown in submerged soil conditions. At the end of April, chlorophyll contents had decreased and the maintenance respiration acquired in spite of continuous transpiration. The rapid change of photosynthetically active radiation did not affect the rates of photosynthesis or stomatal conductance of SARI grown in submerged soil. The rates of photosynthesis and transpiration and chlorophyll contents were measured for two species(c.v. Hongmangmai and Haruhikari) of wheat grown under different soil water conditions. Chlorophyll content tended to increase in dry soil conditions. Hongmangmai had a higher chlorophyll content than Haruhikari, even at the beginning of May. Hongmangmai had large photosynthetic rate and small transpiration rates under dry soil conditions. These confirm that Hongmangmai has a prominent drought stress tolerance. The open system porometer and the chlorophyll meter may be very useful for comparing physiological characteristics of the plant's response to environmental factors and clarifying differences between plant species. |

| 抄録 | Young leaves of barley contain a large amount of gramine, which is one of the factors involved in the resistance of barley against aphids. Using stylectomy by laser beam and EDTA-exudate method, we tried to determine if gramine exists in phloem sap which aphids ingest mainly. Phloem sap was not obtained by laser stylectomy using aphids feeding on young leaves. Components of exudates from cut leaves of barley in EDTA solution are known to be very similar to phloem sap. The time course of sucrose and gramine content of EDTA exudates from barley leaves suggested the existence of gramine in phloem sap. |

| 抄録 | Micrometeorological observations including turbulent fluxes and canopy surface temperatures were made in paddy in the summer of 1997. The sensible and latent heat fluxes were estimated by the gradient method under the assumption of similarity between the turbulent exchange coefficient for momentum and that for heat and water vapor. The surface temperatures measured by a thermal imager and water vapor pressures estimated from surface temperatures and relative humidity were used for temperature and water vapor at the height(d+z0) of U=0, where d is the displacement height, z0 the roughness length and U the mean wind velocity. The sensible and latent heat fluxes estimated by the gradient method depicted typical diurnal varietions. The turbulent fluxes by the present method and eddy correlation method showed fairly good agreement, especially for latent heat fluxes. These results confirmed that this method is a promising one. |

| 抄録 | ORF326, frxC and ORF469 of a transfomable cynobacterium, Synechcystis PCC6803, have sequence similarity with ORF465 on the choroplast genome of a livewort, Marchantia polymorpha, respectively. To elucidate their functions,targeted mutagenesis was performed by transformation with clened DNA in which the ORF was disrupted by insertion of a kanamycin resistancen gene cassette.Streak-purifications of a single colony of each transformant were repeatde to segregate homozygous mutants for disrupted copies, because Synechocystis PCC6803 was reported to have approximately 10 chromosomal DNA copies. Southern blot analysis revealed that mutants for ORF326 had not only disrupted ORF326 copies but also wild type ORF326 copies. This suggests that ORF326 is indispensable for growth under the mixotrophic growth condition used. However, mutants for frxC and mutants for ORF469 had only mutated copies, indicating that they dispensable for growth. Growth and chlorophyll a content of an ORF469-disrupted mutant were compared and chlorophyll a content of an ORF469-disrupted mutant were compared to those of wild type under mixotrophic growth condition, but no significant difference was detected. This indicates that ORF469 is required for neither normal growth nor chlorophyll biosynthesis under thie condition. |

| 抄録 | Monoclonal antibody (MAb) was applied to a double-antibody sandwich ELISA (DAS ELISA) for highly sensitive detection of cucumber mosaic virus. Alkaline phosphatase-labeled MAb with high activity was used to raise the ratio of spocific-and nonspecific-adsorption of conjugate (S/N ratio) on polyclonal antibody coated solid phase. Also the assay with a fluorogenic substrace or an enzyme-amplified assay which is highly sensitive for measurment of activity was employed to increase the sensitivity of the assays. This ELISA systems proved to be more sensitive than the conventional assay using ρ-nitorophenyl phosphate, and could detect 100 pg/ml of purified virus. |

| 抄録 | In order to select higher salt tolerant cultivars of barley,solution culture experiments were carried out with 500 barley cultivars, which were preliminarily selected from 4581 cultivars by exposure to 1-2% of sodium chloride(MaCl) during the germinating stage. The concentrations of NaCl used in the experiments were 2 (control), 150 and 300 mM in nutrient solution.From the results of five solution culture experiments, each of which was carried out with about 100 cultivars, 105 cultivars of barley were selected as relatively about 100 cultivars. Then the final selection was carried out on those 105 cultivars, and it was found that more than 10 cultivars were highly salt tolerant, mainly based on the comparisons of shoot yields under the supply of 300 mM of NaCl.High salt tolerant barley cultivars mentioned above showed 42-86% and 17-30% of the control in shoot yield under the condition of 150 and 300 mM of NaCl, respectively.On three groups of barley,each having more than 10 cultivars, which are high, moderate and low in salt tolerance, ion contents of the plants were analyzed.The results suggest that potassium(K) uptake was comparatively larger in the high salt tolerant goup of barley cultivars,through there was a big variation in sodium(Na) and K contents even within the same group. |

| 抄録 | A system designed to measure the vegetation response to environment was constructed on the basis of the eddy correlation method.It consisted of two sets of a small rapid response sensors; three dimensional sonic anemometer thermometers and infrared CO2-humidity fluctuation meters,and a personal computer for data acquisition. Field tests of the system were made over a barley field in April and May,1990.The turbulent fluxes obtained by two sets of flux measuring system mounted at the same height were in fair agreement. The turbulent fluxes(momentum,sensible heat,latent heat and carbon dioxide) measured at two height wihtin and above plant cannopies and their differences showed realistic diurnal variations.The direction and magnitude of each flux varied depending on the srength or distribution of source and sink within plant canopies. These findings confirmed that this measureing system is promising for quantitative estimate of vegetation response such as transpiration, photosynthesis and respiration in certain canopy layers to environmental variations. |
