| 抄録 | The application of basic slag (BS20 and BS30: basic slag 20 and 30 t ha-1) and aggregate size (A20 and A30: aggregate sizes of soil less than 20 and 20-30 mm) and different techniques (Tech 1: pyrite at top, jarosite at middle, and top soil at the bottom of ridge; Tech 2: top soil at top, pyrite at middle, and jarosite layer at the bottom of ridge) exerted significant (p≤0.05) positive effects on the growth and yield of eggplants cultivated under field condition and the effects varied not only with the kinds and amounts of amending materials but also with the techniques applied. The soil showed a silty clay loam texture, initial pH value of 4.1, pyrite content of 55 g kg-1, base saturation of 47%, ECe value of 3.6 dS m-1, high exchangeable Fe3+ and Al3+ contents of 1.47 and 5.29 cmolc kg-1, respectively. The pH value of the average soil data obtained from all the treatments during fruit set (95 days after transplantation) of eggplants was found to be increased in pH by 1.2 units higher compared with the control (i.e. initial pH value). The contents of P, K, Ca and Mg in the average soil data during fruit set were found to be increased (IOC = increased over control) by 41 to 127% IOC, while the contents of Al3+, Fe3+, Na+, Cl- and SO4 2- in the soil were found to be decreased by 28 to 92% IOC. The different treatments on eggplants grown under the modified-plain-ridge-ditch techniques in the Cheringa acid sulfate soil significantly (0≤0.05) increased the fresh yield of eggplants, and the increment was more pronounced with Tech 2. The maximum yield of 17.8 t ha-1 of eggplant for Tech 1 and 20.1 t ha-1 for Tech 2 were recorded by the application of BS30 in the soils of smaller aggregates (A20) at the ridges of Tech 2, followed by the A30BS30 treatments in both the techniques. The lowest quantity of 1.7 t ha-1 yield was recorded by the control treatment. The eggplants grown in the ridges of both the techniques exhibited the best responses on N, P, K, Ca and Mg contents in eggplant tissues during fruit set. As expected, the lowest contents of these nutrients in the eggplants were recorded in the control treatment. Sulfur content of the eggplants grown in the control plots was 3.6 g kg-1 and was in the range of adequate S content (4 g kg-1). However, the S contents in the eggplants grown in different treatments were significantly (p≤0.01) lower compared with the adequate level. The effectiveness of the treatments for the reclamation of the soil in relation to the growth of eggplants was: Tech 2 > Tech 1, BS30 > BS20, and A20 > A30. The results suggest that the physicochemical properties of the soil, and the growth, yield and nutrition of eggplants were strikingly improved by the application of flash leaching followed by BS30 and A20 treatments in the ridges of Tech 2, and are regarded as the best reclamation measures for this acid sulfate soil. |

| 抄録 | 胸部専用の新しい増感紙／フィルムシステムについて物理的画質特性を測定し、従来のシステムと比較を行った。測定した新システムは、日本コダックのインサイトシステムからHC/IT-1、富士メディカルシステムのADシステムからHG-M/UR-1、コニカのEXシステムからXG-S/ES-C である。従来のシステムとして富士メディカルシステムのHR-4/Super HR-S を使用した。その結果、新システムは22～73％感度は高く、特性曲線においては低濃度部を持ち上げ、最大コントラストは高濃度側にシフトしていた。空間周波数2cycles/mmで相対鮮鋭度を比較すると、新システムが10～30％程度の低下となっていた。ノイズは、濃度1.0で新システムが35～46％の減少となった。以上より、新システムは、縦隔部の濃度を上げ、粒状性の改善を重視した設計となっていることが分かった。 |

| 抄録 | Sensitivity to water condition during germination is an important character in malting barley because it affects malt poduction. Water sensitivity in malting barley is defined as the defference in germination percentage between the seeds in standard and excess-water conditions. Usually standard and excess-water condition means 4 and 8 ml water in a 90 mm perti dish, respectively. Takeda and Fukuyama (1983) examined more than 4,000 barley accessions and found 0～100% water sensitivity. This means complete to no suppression of germination by an excess-water condition. In this study, quantiative trait loci (QTL) analysis was applied to analize the inheritance of water sensitivity. Two sets of doubled haploid (DH) populations derived from Steptoe×Morex (S/M) and Harrington×TR306 (H/T) crosses,were grown in the experiment field of the Research Institute for Bioresources, Okayama University. Bulbosum method was adapted to develop DH lines (Chen and Hayes 1989). Water sensitivities of 150 (S/M) and (H/T) lines and their parents were evaluated using 50 seeds each and the germination test (25℃, 4 days) was repeated four times. Water sensitivity showed a large variation (Fig.1) and the heritability of the trait was 0.78 and 0.72 in S/M and H/T, respectively, indicating that about three-quarters of the phenotypic variance was genetic in origin. Three (S/M) and one (H/T) significant QTL were detected and 23% (S/M) and 25% (H/T) of the phenotypic variance was explained by the QTL. These QTL were located on chromosomes 2H,3H,6H and 7H (Table 1, Fig. 2). QTL relating to germination traits were lacated near the QTL controlling water sensitivity (Fig. 3). Interaction among the QTL was small (Table 2). Marker-assisted selection was effective (Table 3). |
