High sugar content of sorghum stalk is an important factor in the sorghum silage production. To identify the genomic regions controlling sugar content and to develop molecular markers linked to sugar content in sweet sorghum, we used an F2：3 segregating population consisting of 207 individuals derived from a cross between a high sugar content inbred line, Early Folger, and a normal inbred line, N32B, for genetic linkage mapping and quantitative trait locus （QTL） analysis. We constructed a genetic linkage map spanning 983.5 cM based on a total of 327 markers comprising 31 restriction fragment length polymorphism （RFLP） markers, 254 amplified fragment length polymorphism （AFLP） markers, and 42 simple sequence repeat （SSR） markers. In the 20 linkage groups detected, 98.2% of markers aligned to the 10 linkage groups of sorghum. Variations in sugar content at different growth stages and among internodes suggested that the sugar content of middle internodes is stable and suitable for measuring at early dough stage. The broad sense heritability （hB0 of sugar content was 0.64 and 0.62 estimated from the data of F3 families and each parent in 2003 and 2004. We identified one and two QTLs accounting for 22.2 to 25.0% of phenotypic variance using simple interval mapping method in 2003 and 2004, respectively. These two QTLs showed a negative additive effect, and over-dominance effect. A QTL on LG-D was detected in both two years. Above results will be help us to understand the genetic mechanism of sugar content in sorghum and the QTL detected in this study might be useful in the improvement of sugar content by marker-assisted selection.

In a deuterium operation on the Large Helical Device, the measurement and control equipment placed in the toms hall must survive under an environment of radiation, To study the effects of gamma-ray irradiation on the equipment, an irradiation experiment is performed at the Cobalt-60 irradiation facility of Nagoya University. Transient and permanent effects on a personal computer, media converters, programmable logic controllers, isolation amplifiers, a web camera, optical flow meters, and water sealing gaskets are experimentally surveyed. Transient noise appears on the web camera. Offset of the signal increases with an increase of the integrated dose on the programmable logic controller. The DeviceNet module on the programmable logic controller is broken at the integrated dose of 72 Gy, which is the expected range of the integrated dose of the toms hall. The other equipment can survive under the gamma-ray field in the toms hall.

为弄清光周期对一种亚热带蜚蠊(Periplaneta japanna)若虫发育的控制机理,检测了光周期对冲绳(26°N)和八丈岛(33°N)两个地理种群若虫发育的影响。结果表明,光周期显著影响两地理种群的若虫发育,然而,冲绳和八丈岛种群间显示不同的光周期反应模式。冲绳种群在长日条件下(LD16∶8h)若虫发育显著快于中间日长(LD14∶10h)和短日条件下(LD12∶12h)的若虫发育,孵化后60d或120d将若虫自LD16∶8h向LD12∶12h转移,若虫发育受到抑制,而自LD12∶12h向LD16∶8h转移,则促进若虫发育。八丈岛种群的若虫在短日条件下发育最快,其次是中间日长,长日条件下若虫发育最慢,孵化后60d或120d将若虫自LD16∶8h向LD12∶12h转移抑制若虫发育,反方向转移的若虫快速发育。两地理种群间不同的光周期反应模式可以认为是趋异进化的结果。
