Results:(1) The conchosporangia of brown yellow mutant was smaller and mature time was 15 days later than the parents. Thallus grew slowly in early stage, but average daily growth rate reached (7.50±1.18) cm after blade length was over 60 cm.(2)The emerald conchocelis were easy to mature and had special developmental mode that the spherulocytes can directly develop into sporangial branchlets and conchosporangia without thick conchocelis stage. Emerald blades were low in RPE with just (6.4710±0.0184) mg/g dry mass. The thallus grew quickly, average daily growth rate reached (11.95±2.33) cm after blade length was over 60 cm.(3) The conchocelis filaments of breen mutant were thin and short. Thallus grew slowly and had low contents of three phycobiliprotenin and chlorophyl.

实验进行50d。结果：(1)褐黄色突变体藻蓝蛋白和别藻蓝蛋白含量低；孢子囊枝的细胞较小，且大量形成时间比亲本晚15d；幼苗培养初期日平均生长量仅为(1.22±0.28)cm，当叶片长到60cm左右时生长优势逐步凸显，日平均生长量可达(7.50±1.18)cm；(2)翠绿色丝状体容易成熟，发育方式特殊，营养藻丝不经过藻丝加粗阶段，直接由球形细胞发育成孢子囊枝和壳孢子囊；翠绿色叶状体藻红蛋白含量低，仅有(5.5130±1.0496)mg/g；叶状体生长快速，60cm长的藻体日平均生长量高达(11.95±2.33)cm；(3)褐绿色突变体藻蓝蛋白、别藻蓝蛋白和藻红蛋白这3种色素蛋白和叶绿素的含量均较低；藻丝细胞短且细，叶状体生长速度较慢。

Based on the situation in Shanghai. this paper applys the theories of in tegration of city and countryside. agriculture in city countryside. agricultur- al modernization arid sustainable agricultural development to deal with the achiveruen t of national industrialization and modernization lie in agrieultura~ modernization ?-? integration of city and countryside -~-? urbanization of rural areas-?-? agriculture in city countryside this is the main clue of the paper. In the view cf history and reality with overall and system. this paper appl~is analysis method of combination of normative and positive. quantattve and qualitive. long-term and short-term and, internal, external arid Shang- hai to discuss relationship among agriculture in city countryside. agricultural modernization and sustainable developrncnt, the history. present and re- straint factors of sustainable development of modern agriculture in city coun- tryside in Shanghai is further analysed. So concepts. goals. index system. selective patterns, developmental strategys and measures of sustainable de- velopment of modern agriculture in city countryside are raisen.

本文立足于上海，依据城乡一体化、都市农业、农业现代化和农业可持续发展理论，围绕着实现国家工业化与现代化的出路在于把农村、农业剩余劳动力转移出来，实现农业现代化——农业剩余劳动力转移必须打破城乡分割，实现城乡一体化——打破城乡分割又必须实现农村城镇化——农村城镇化前提下的农业一定是都市农业的中心线索，全面系统地从历史与现实的角度，运用理论与实践、规范与实证、定性与定量、国内外与上海以及点面相结合的分析方法，探讨了都市农业、农业现代化与可持续发展的关系，分析了上海现代都市农业可持续发展的历史、现状和制约因素，提出了现代都市农业可持续发展的概念和目标、指标体系、选择模式以及发展战略和对策。

After being induced to differentiate in vitro, cells with various morphologies showed β-gal activity, including nerve cells, neuroglial cells, epithelial cells. We also detected β-gal activity in a wide variety of tissue elements in solid tumors made by injecting the MC15 and MA34 cells into syngenic mice. Then we produced chimeric embryos by injecting the MC15 cells into Kunming blastocysts and recovering the embryos at various developmental stages.

SiCMVIE(Simian Cytomegalovirus Immediately Early)启动子是一个强启动子，本文首次将SCMVIE启动子应用到ES细胞途径上制作嵌合鼠，并通过lacZ基因在ES细胞和早期嵌合胚胎中的表达，表明该启动子是一个能在小鼠多数组织表达的启动子，这与1993年Peppel等人用原核显微注射法获得的转基因小鼠上所得的有关结果是基本上是一致的。

In the study, a set of near isogenic lines of CMS-S, S-Mo17Rf3Rf3 and S-Mo17rf3rf3, were adopted, and TdT-mediated dUTP nick-end labeling, in situ immunolocalization of cytochrome c and DNA ladder assay were employed to study the programmed cell death process on cytology and DNA level. The microscope observation evidenced that tapetal cells of fertile anthers kept intact until microspores, and then were disintegrated on later developmental stage.
