| 1 | Colletotrichum species associated with cultivated citrus in China显示文摘There have been considerable advances in the understanding of species concepts in the genus Colletotrichum.This has lead to the need to carry out fresh surveys of Colletotrichum species associated with important hosts.Colletotrichum species are associated with Citrus plants as saprobes,important pre-harvest and post-harvest pathogens,as well as endophytes.In this study,a total of 312 Colletotrichum strains were isolated from leaves,shoots and fruits of cultivated Citrus and Fortunella species with or without disease symptoms across the main citrus production areas in China.The morphology of all strains were studied and multilocus(ACT,TUB2,CAL,GAPDH,GS,ITS)phylogeny established.Strains were from four important species complexes of Colletotrichum,namely C.gloeosporioides species complex,C.boninense species complex,C.acutatum species complex and a final group including C.truncatum,which was rare on Citrus species.The species belonging to the C.gloeosporioides species complex comprised C.gloeos porioides and C.fructicola,the C.boninense complex comprised C.karstii and a new species C.citricola and the C.acutatum complex included a new species,C.citri.The ability of strains to cause anthracnose on citrus fruits was tested by inoculation and strains of Colletotrichum gloeosporioides,C.fructicola and C.truncatum were pathogenic. | F.Huang G.Q.Chen X.Hou Y.S.Fu L.Cai K.D.Hyde H.Y.Li | 2013 | Fungal Diversity2013，，4： | 7 |

| 5 | SUPERPLASTICITY OF A WATER-QUENCHED AND TEMPERED 40Cr STEEL显示文摘The superplastic deformation characteristics, of commercial 40Cr (i.e., 5140) steel that was water-quenched only 1 times and subsequent high-temperature tempered, were investigated. The results showed that the 40Cr steel has a fine grain of 10-15μm at room temperature, and exhibits a tensile elongation of 304%, a true flow stress of 89.3MPa and a strain rate sensitivity m-value of 0.227 at the initial strain rate of 1.0×10-3s-1and at the temperature of 750°C. The final fracture is caused by the development of neck. The experimental result of elongation is in good agreement with the theoretically predicated value according to the analytical expression (where ef, m, f, nv and ε is respectively elongation, average strain rate sensitivity, initial geometric defect, average strain hardening sensitivity at constant deformation velocity and average true strain). The fracture surface is intergraular, and superplastic deformation induces an equiaxed and grown grain. Decreasing strain rate increases tensile elongation and strain rate sensitivity m-value. The primary superplastic deformation mechanism is thought to be atom-diffusion-controlled grain boundary sliding. | X.J.Xu G.L.Liu L.JShi X.N.Cheng L.Cai | 2004 | Acta Metallurgica Sinica(English Letters)2004，17，5： | 0 |
