B Of the six basic media MS, MS1/2 (half-strength of MS salts and vitamins), WPM, DKW, B5 and SH, MS1/2 was the most proper one to induce somatic embryos. Somatic embryos generally regenerated directly from excised zygotic cotyledons. PGRs combination affected somatic embryogenesis significantly. Medium with NAA 1mg/L, TDZ 0.05mg/L, IBA 2—10mg/L combined with BA 10mg/L, or IBA 10mg/L integrated with BA 0-2mg/L gave the highest induction rate. Excised zygotic hypocotyls had the strongest potential to produce callus. Callus induction was also affected significantly by media and PGRs. The proper callus induction condition was MS1/2 medium containing NAA 1mg/L, IBA 10mg/L, BA 2-5mg/L and TDZ 0.05mg/L. Harvest period affect somatic embryogenesis significantly. Zygotic embryo explants collected from the end of July to the middle of August had strong potential to generate somatic embryos, when endosperm finished solidification, different parts of the embryos were completely formed, the size of embryos occupied about 2/3 of the embryo sac. Provided with optimized conditions, direct somatic embryogenesis rate can attain to 33. 68%, and callus induction rate of hypocotyls was up to 90.7%. Cytological observation on megasporogenesis and zygotic embryogenesis of Manchurian ash showed that the ovary was twicarpellum, twilocular with two ovules each loculus. The ovule was tenuinucellar and anatropous, with one megasporcocyte. The development of embryo sac is of the Polygoum type.

体细胞胚胎发生研究的结果表明：(1)成熟过程中的合子胚是诱导水曲柳体细胞胚胎发生的最佳外植体材料；(2)在所试验到的MS、MS1/2（将MS的所有成分均减半）、WPM、DKW、B〓、SH等六种基本培养基中，MS1/2是最适合诱导水曲柳体细胞胚胎发生的基本培养基；(3)水曲柳的体细胞胚胎发生以直接发生为主，体细胞胚主要来自于从合子胚分离的完整子叶；(4)培养基中的激素组合对水曲柳的体细胞胚胎发生有显著影响，诱导直接体细胞胚发生较好的激素组合有NAA 1mg/L+IBA 2，5，10mg/L+BA 10mg/L+TDZ 0.05mg/L和NAA 1mg/L+IBA 10mg/L+BA 0，2mg/L+TDZ 0.05mg/L；(5)合子胚分离的下胚轴具有最强的愈伤组织诱导潜力，少数愈伤组织可以分化出体细胞胚；(6)愈伤组织的诱导也受培养基和激素配比的显著影响，最适宜诱导的培养条件为MS1/2+NAA 1mg/L+IBA 10mg/L+BA 2，5mg/L+TDZ0.05mg/L；(7)采种时间对体细胞胚胎发生有显著影响。7月末到8月中旬的合子胚具有较强的体细胞胚发生潜力，此时种子尚未成熟，胚乳已呈固态，种胚的各个部分已分化完全，种胚体积占胚腔的大约2/3；(8)在各自综合的最适条件下，完整子叶的体细胞胚诱导率可达33.68%，下胚轴的愈伤组织诱导率可达90.7%。

Prain, Trifolium repens Lam, Aeachynomene Mica L, Indigofera bungeana Steud.The same strains used in numerical taxonomy were analysed by BOXAIR-PCR fingerprinting. All tested strains were clustered into 47 groups at the similarity level of 50%. Compared with the result of numerical taxonomy, strains belonged to one phenon in numerical taxonomy always distributed into several BOXAIR-PCR groups, most of reference strains come from one recognized rhizobial species were not grouped together.

B(来源：dd9dAB94C论文网www.abclunwen.com)OXAIR-PCR指纹图谱的聚类结果显示：全部供试菌株在50％的相似性水平上分为47群，与数值分类的结果相比较，其分群的结果更分散，在数值分类80％相似性水平上位于同一表观群的供试未知菌株大多分布于几个综合的BOXAIR-PCR群内；另外在数值分类中来自同一个种的已知根瘤菌参比菌株几乎都聚在同一个表观群，而在BOXAIR-PCR分析中，已知参比根瘤菌的同一个种内的大部分菌株都单独成群。

Results showed diural variations of leaf Pn displayed bipeaked curve model, indicating the depression of photosynthesis at noon. Leaf Pn rate in June was higher than in September; Compared to leaf Pn, Cs had a similar changing curve, Cs in June was higher than in September. While diural variations of intercellular CO2 concentration were opposite to that of leaf Pn and Cs, decreased before 1200,increased after 1200, decreased again at 1600,after 1600 increased again; diural variations of climatic factors displayed single peaked curve model, peakedvalue occurred at 1400,and their influences on physiological factors were indirected and integrated.

Doing SEO to update a website is indispensable of course, especially information of company station product is fixed, and all alone to the station search that does not renew engine is to won't give tall weight, want to rise collect be about to replace news more, some people want to optimize the website of single page through SEO technology very much, I persuade you to fasten laborious, do not have valuable website to, searching engine is won't of appeasement, although your outside catenary also is infructuous more again, though Baidu emphasizes particularly on content, gu Ge emphasizes particularly on outside catenary, actually every rank that searchs engine is each element is integrated, it is a few conclusion that reach under certain website coincidence only.

做SEO更新网站当然是必不可少的了，尤其是企业站产品信息是固定的，而对于不更新的站搜索引擎是不会给予高的权重的，想要提高收录就要多更新新闻，有的人很想通过SEO技术来优化单页面的网站，我劝你们别费劲了，对于一个没有价值的网站，搜索引擎是不会姑息的，即使你的外链再多也是徒劳，虽说百度侧重内容，谷歌侧重外链，其实每个搜索引擎的排名都是各项因素综合的，只是某些网站巧合之下得出的一些结论。
