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%。

The research method is combining historic happening with scientific research.This paper is composed of seven chapters. The preface explains briefly the reason of choosing this topic and its significance, as well as the existent research situation in the academic circle.The first chapter presents the subjective and objective historical condition of the formation and development of his view about population quality in four aspects.The second chapter gives a full play to its evolution: it gestates and germinates before the failure of the revolution in 1911, takes shape and develops in the period of Base Area. The following period after the founding of People's Republic of China is its mature time. This view also experiences twisty developments in China's exploring period of socialism.The third part focuses on its major connotations, including Mao's narration on the connotation of Population quality, his analysis of contradiction between population quality and Chinese revolution and construction and of their significance, and the way to enhance Chinese population quality.The fourth chapter makes analyses of philosophical support of Mao's view from three "adherences": adherence to basic principle of seeking truth from facts;adherence to the common acknowledged fact that the people is the main part of history;adherence to the dialectical relation between being and consciousness.

The cumulus cells of OCC were cut off and dispersed by 1 mL syringe. The cumulus cells were co-cultured with the immature oocytes retrieved from the COH cycles after they adherent to the bottom of the dish. The immature oocytes were experienced IVM procedures in different culture media. They were divided into 3 groups(the oocytes at germinal vesicle stage from one woman were allotted to the same group randomly). Group 1: basic culture medium+ human follicular fluid; Group 2: solution A+ cumulus cells; Group 3: solution A+ OCC+ follicle stimulating hormone + epidermal growth factor. Then, the maturation rate, fertilization rate and formation rate of available embryo were observed.
