纵坑切梢小蠹大发生原因探讨

本文从种群系统出发,全面分析了纵坑切梢小蠹与云南松的相互作用.及环境多种因素对该虫大发生的综合影响.认为在虫害发生初期,云南松树势衰弱是纵坑切梢小蠹大发生的基本条件,当虫害猖獗漫延时,该虫可以攻击并致死健康树.纵坑切梢小蠹种群数量便成为虫害进一步加剧的主要因素.气候、寄主抗性、林地条件、森林管理对害虫种群消长有重要影响.昆明地区气候条件对于纵坑切梢小蠹生长繁殖都非常有利,是该虫得以在短期内爆发成灾的主要原因.

Isolation and characterization of a new species of Vibrio-Vibrio olivaceus sp.nov. from diseased flounder （Paralichthys olivaceus temminck et schlegel）

One kind of pathogenic bacteria was isolated from diseased (or dead) flounder (Paralichthys olivaceus L.) which expressed bacterial septicaemia. The phenotyic information of the 10 pure cultures was studied extensively, including morphological characteristics, colony characteristics in different media, physiological and biochemical characteristics, and the mol%G C ratio of the DNA for representative strain. The results showed that the isolates belonged to a new species of Vibrio. In addition, the representative strains have been re-checked by China Center for Type Culture Collection (CCTCC), the results were the same as ours, the examined strains were also regarded as a new species of Vibrio, and designated as Vibrio olivaceus sp.nov. by its isolated fish (Paralichthys olivaceus) based on its biological properties following Rules of International Code of Nomenclature of Bacteria. In the same time, we conducted studies on the serum homology of isolates, pathogenicity of isolates by experimental infection. The results showed that all the isolates were of serologic similarity and the isolates have strong pathogenicity to flounder. Inspection to pure cultures and isolates from liver of moribund fish from infection experiment by fluorescent antibody technique showed the feasibility of fluorescent antibody technique as an auxiliary method of examination.

Construction of a genetic map with SRAP markers and localization of the gene responsible for the first-flower-node trait in cucumber (Cucumis sativus L.)

Cucumber (Cucumis sativus L.) is an annualclimber originated from the tropic rain forest area inthe south of Himalayas, which belongs to the Cucur bitaceae family. Cucumber is one of the importantvegetables in the world, and its planting area is sec ond only to that of tomato[1]. However genetics re search on cucumber obviously drops behind that of thelatter. The classic genetic map of cucumber, with sixlinkage groups, is composed of more than 100 genesfor color, morphology, and dise…
