Adding the Al-dopant to the Zinc Oxide crystal structure results in changes that affect the optical and nonlinear characteristics. Presented results indicate that the magnitude of X<sup>(3)</sup> was enhanced at single experimental wavelengths;however, across the broadband experimental spectrum, the effect of Al-doping remained relatively constant. The observed enhancement of third-order nonlinearity was purely from the bound electronic response. The observation is attributed to increased charge carriers and spontaneous polarization in the Zinc Oxide and Al-doped Zinc Oxide crystal structure.展开更多

[ Method] Using mi- crosatellite markers (ISSR) molecular maker technology, combined with bulked-segregant analysis (BSA) method, the molecular makers for gene linkage with re- sistance against S. trifoliorum were screened from five resistant plants and seven susceptible plants. Leaf in vitro inoculation method was used to carry out resistant verification on 94 hybrid plants in Ft generation of high resistant No. 83 ~ high susceptible No. 4. [ Result] Among 93 ISSR primers, 35 primers could produce clear and stable amplification bands, and six of them could produce 9 specific bands between resistant and susceptible DNA pools. Resistance verification result showed that 825 - 1400, 831 - 1480, 850 - 1800, 858 - 1600, 866 - 1900, 888 - 1400 could be used as ISSR molecular makers of the resistant gene against S. trifoliorum in M. sativa. [Conclusion] The results provided basis for the further research on mapping,, cloning and genetically modified of resistant gene against S. trifoliorum in M. sativa.展开更多
