几种草地早熟禾种子萌发期耐盐性的比较研究

选用草地早熟禾的5个品种为试验材料,分别置于6个浓度梯度下的Na2CO3溶液中,进行萌发期的盐胁迫处理,以发芽指数、活力指数相对下降率和电解质外渗率及胚根、胚芽生长量等作为指标,比较其耐盐性.试验结果表明,5种草地早熟禾品种的耐盐性依次为:Poa PratensisL.America（美洲五）>Poa Pratensis L.Conni（康尼）>Poa PratensisL.Midnight（午夜）>Poa Pratensis L.Park（公园）>Poa Pratensis L.Nimbus（光环）.

王古生平及其交游

王古是三槐王氏中比较出色的人物，官至户部尚书。为政清廉，为人正直，一生遭际坎坷，却能始终如一。他的政治观与司马光比较接近，故最后被打入元祜党人，贬谪到死。他与同时代的许多人学士都有过从，对苏轼关照尤甚，使苏轼能在惠州那样险恶的环境中，安然度过谪宦生涯。

Detection of Grass Carp Hemorrhage Virus （GCHV） from Vietnam and Comparison with GCHV Strain from China

Grass carp plays an important role in small-scale aquaculture in Vietnam. However, a severe disease, known in Vietnam as “Red Spot Disease“, is causing significant economic loss in grass carp aquaculture. In this study, the tissue samples isolated from the grass carp with Red Spot Disease in Vietnam are investigated and eomparied with the control GCHV isolated in China by experimental infection, culture cell infection, serological cross reactivity, and RT-PCR amplifica-tion. Infected grass carp exhibits hemorrhage symptoms about 5 days after experimental injection with GCHV-V (Vietnam) strain. The symptoms and lethality induced by the GCHV-V strain are identical to that induced by the Chinese GCHV-9014 strain. The Chinese GCHV-873 strain in-duces typical cytopathogenic effects in 4 cell lines, such as CIK, CAB, FHM and GCO, from the6 fish cell lines examined. No cytopathogenic effects are observed in all the 6 examined cell lines,including CAB, FHM, CIK, EPC, CCO and G(X), infected by the GCHV-V strain and GCHV-9014 strain. Immunodiffusion assays demonstrate an obvious cross-reactivity among three GCHVstrains. Precipitin lines are clearly observed not only between the anti-GCHV-873 serum and thetwo strains GCHV-873 and GCHV-9014, but also between the anti-GCHV-873 serum and the GCHV-V strain. GCHV can be detected by immunodiffusion assays after three generations of blind propagations in the cell lines inoculated by GCHV-V strain. This implicates that GCHV-Vviruses have been replicated and amplified despite there being no cytopathogenic eifects observed in these examined cell lines. Three genome segments of GCHV, including S8, S9 and S10, are amplified by three sets of PCR primers designed according to the segment sequences published re-cently. The Q8fp and Q8rp primer set specific for genome segment S8 amplifies a 955 bp frag-ment from the extracted sample of diseased fish with Red Spot Disease, and the fragment size is i-dentical to that amplified by the same primer set from control GCHV-873 strain. Simultaneously,the Q9fp and Q9rp primer set specific for genome segment S9 generates a same 635 bp product,and the Q10fp and Q10rp primer set specific for genome segment S10 produces a same 697 bp fragment from both template samples of diseased fish with Red Spot Disease and control GCHV-873 strain. The RT-PCR amplification and corresponding size comparison data indicate that the three GCHV-V genome segments extracted from the diseased grass carp with Red Spot Disease in Vietnam should be identical to that in control GCHV-873 strain from China. The data confirm that the causative agent of grass carp Red Spot Disease in Vietnam is a virus, and the virus is closely similar to GCHV strain in China.
