For this purpose, genotyping was performed on males of 18 Angus, 23 Jinnan cattle, 20 Limousin, 28 Luxi cattle, 26 Qinchuan cattle, 29 Simmental, 29 Charolais. In the association studies traits of interest were analyzed using the RFLP-PCR and GLM procedure of SAS 9.1 and least square means of the genotypes were compared by the Tukey' s test.

基于这一目标，应用RFLP技术对18头安格斯，23头晋南牛，20头利木赞，28头鲁西牛，26头秦川牛，29头西门塔尔牛和29头夏洛莱牛进行了基因型分型，SAS 9.1的GLM过程中的Duncan's 检验对不同基因型之间进行了多重比较分析，结果表明，EcoRⅤ位点与体重、日增重、眼肌面积和嫩度之间存在显著生物学相关，并且AG基因型个体与其它基因型相比在日增重和嫩度上存在显著差异（p0.05），而AA基因型个体相对于其它基因型具有较大的眼肌面积（p0.05）。

The results showed that it was invalid to apply Zn fertilizer alone, but biomass production obviously increased while Zn and P fertilizer applying together during maize seedling stage, P and Zn showed positive interaction effects in carbonate Chernozem of seriously lack of P. While applying P and organic fertilizer, the contents of Zn were 19.4～23.3 mg/kg, P/Zn...

结果表明：在严重缺磷的碳酸盐黑钙土上，单独施锌无效，锌磷配施玉米苗期生物学产量增产明显，磷与锌呈正交互作用；施磷和有机肥时，玉米苗期锌含量下降到 19.4～ 2 3.3mg/kg，磷/锌比值大于 140 ，玉米易出现白苗症；施入土壤的锌第 1年固定率最高可达 65%～ 88%，第 2年达 85%～ 95%，第 3年达 88.5%～92 。4 %；磷与锌配施既能提高锌的利用率又能提高磷的利用率

The detailed pathological lesions and the dynamic location of AEV in natural and experimental cases of chicken, chickling and embryos were reported. And AEV agar gel precipitin antigen and an inactivated oil-emulsion vaccine against AE were produced.

According to the present situations of protected area in China and referring to the definition and category abroad, we suggested the forest natural protected area mainly include three types as follow: Nature Reserves (NR; types of forest eco-system), Forest Parks and Public Welfare Tree Farm. Researches of evaluation on ecotourism resources of forest natural protected area focused on two aspects basically: to appraise and account the ecotourism resources monetarily from the standpoint of pure economics; to assess the exploitability of ecotourism resources based on the theories of conservation biology and ecology, in which finding the reasonable equilibrating point between protection and: utilization was emphasized. On the studies of development pattern of forest ecotourism resources, it is necessary to deal with the relationship between protection and exploitation correctively, namely to put the protection as the first consideration and balance the "Tree r.1ajor Benefits" so that prompting the virtuous circle afforest ecotourism.

根据我国自然保护地的实际情况，参考国外自然保护地的定义与分类方式，可认为我国的森林自然保护地主要应主要包括森林生态系统类型自然保护区、森林公园及公益林场三种类型；森林自然保护地的生态旅游资源评价研究主要集中在两方面：一是单纯地从经济学角度对旅游资源游憩价值进行货币化评价与核算，二是从保护生物学和生态学角度对资源的可开发性进行评价，其侧重在于找到保护与开发的的科学平衡点；在森林自然保护地旅游资源的开发模式研究上，必须正确处理开发与保护的关系，把保护放在第一位，坚持"三大效益"兼顾的原则，才能实现森林生态旅游资源开发与保护的良性循环。

Recently, Thellungiella halophila, a close-relative ofArabidopsis thaliana, which is been suggested and be developed as a new salttolerance model plant. Thellungiella halophila is a salt-tolerance crucifer with a shortlife cycle, small genome, and with high sequence similarity(about 90-95% on cDNAlevel), similar heredity characteristics and growth habits with Arabidopsis thaliana.So it is convenience for T. halophila to benefit from a lot of Arabidopsis thalianainformation data.

最近，另一个盐生植物盐芥被提议为研究植物耐盐性的模式系统，它是拟南芥的近缘，为生长周期短、基因组较小、耐盐性较强的十字花科的盐生植物；在cDNA水平上与拟南芥有大约90-95％的同源性，因此，可以方便地将拟南芥的很多信息移至盐芥耐盐性的分子生物学研究；而且，盐芥具有拟南芥很多同样的优点以作为实验系统。
