According to the space - tim e maturation during the development of the vessel elements in primary vascular system : the vessel elememts of the cotyledons and the lower portion of cnz formed firstly, then downward hypocotyl - root zone, at length, the vessel elememts of the upper and middle portion of cnz and epicotyl - shoot region connected with each other, the result uphold the seedling partition model that divides seedling into cnz, hypocotyl - root region and epicotyl - shoot region
根據金魚草幼苗初生維管系統導管分子發育的時空性,即子葉和子葉節區下部導管分子先形成,然後向下形成下胚軸-根區的導管分子,最後子葉節區中、上部與上胚軸-苗區的導管分子再發生連接,據此支持將幼苗分為子葉節區、下胚軸-根區和上胚軸-苗區的幼苗分區模型。Through cultivating five cold - season turfgrass ( lolium perenne, agrostis stolonifera, festuca rubra, festuca arundinacea, bromus inermis ) in basin, their drought to lerance indexes, including the planting height, the root growth, the relative water content of leaves, the penetration of membrane, were comprehensively evaluated to compare their drought tolerance
摘要採用盆栽育苗法,在5種冷季型草坪草苗期連續乾旱脅迫下測定植株高度,根系生長,葉片相對含水量和質膜透性等抗旱指標,以綜合評價5種冷季型草坪草的抗旱性能。At the same time, to analysis whether it is suitable to implement american language teaching for young children, and to explore the difficulty of american language teaching at present
然而在教育部宣布幼稚園不得教授美語等一連串的禁令復,不禁令人反思,幼兒階段教授美語到底是向下紮根或是揠苗助長?Two strains of prrsv were isolated from the swine infected with prrsv in shangdong province and daqing area, in order to clarify the source and genetic background of porcine reproductive and respiratory syndrome virus ( prrsv ) from different parts of china, thus providing theoretic basis for the study of vaccine against it. the prrsv was cultured on mark - 145 cells for 5 ~ ~ 6 passages. when the cpe was obvious, the virus was harvested and purified
為了弄清我國不同地區prrsv的來源以及其遺傳學背景,為疫苗學研究提供理論根據,本研究在ch - 1a株完整的基因組獲得以後,從流行於我國山東( sd )和黑龍江大慶( dq )地區疑似prrs的豬體內分離到prrsv ,在mark - 145細胞上盲傳5 6代,細胞出現明顯病變以後,收獲病毒液,然後提純,提取全病毒rna ,經過反轉錄、 pcr擴增獲得結構基因orf2 7的目的基因片斷,然後與pmd - t載體連接,轉化,得到陽性質粒后進行測序,並將其與ch - 1a株進行了比較分析,同時對這兩個毒株的結構基因組的理化性質進行分析。Seedlings may survive either through an early onset of the flood in the year after germination, or seedlings may survive through silty and clayey soil layers, which store water better than sand
