14 species are edible plants, 37 species are medicinal plants, 11 species are ornamental plants and31 species are feeding plants, the major types of halophytic vegetation in hebei province include ptenothalophyta such as tamarix chinensis brush and siberian brush, and littoral halophytic vegetation such as succulent vegetation, poion, chomophyte and etc. epidermal cell exosporium of tamarix chinensis blade is papillous and capillaceous ; stoma and salt - secreting gland are under the epidermis ; differentiation level of mesophyll tissue is rather high ; porder camber is obvious ; and mechanical tissue is developed
河北省鹽生植物的經濟價值較高，其中可食用的鹽生植物共計14種，可藥用的鹽生植物37種，可飼用的鹽生植物31種，具有觀賞價值的鹽生植物11種，可以作為纖維植物計約9種。河北省主要鹽生植被類型有檉柳灌叢、西伯利亞白刺灌叢等落葉灌叢和肉質型、禾草型、雜類草型鹽塵植被等濱海鹽生植被。 -
There are many adaptive changes in the two research subjects ( artemisia. songarica schrenk. and seriphidium. santolinum ( schrenk ) polijak. ) in morphology and anatomy, such as with the increase of the daily age, the root - shoots ratio increased ; the root became stronger ; the ratio of leaf volume and leaf area increased ; the volume of epidermic cell decreased ; the cut - icle and phellem layer on the surface of root thickened. stoma caved in leaf ; epidermal hair of leaf and stem well - developed, palisde tissue developed well, the cell gap decreased ; the spongy tissue disappeared ; leaf is kinds of isolateralthat is the typical xeromorphic structure ; crystal cell and fibric cell increased ; conducting tissue and mechanical tissue developed well ; bundle sheath appeared
實驗研究的兩種菊科（ compositae ）植物（準噶爾沙蒿（ artemisiasongaricaschrenk ）和沙漠絹蒿（ seriphidiumsantolinum （ schrenk ） poljak . ） ） ，形態解剖方面的變化表現為：隨日齡增加，根長/株高比值日益增大；根系逐漸發達；體積與葉面積比逐漸增大；表皮細胞體積變小；角質層增厚；根外部出現加厚的木栓層；氣孔下陷；葉、莖部的表皮毛密布，柵欄組織日益發達；而細胞間隙日漸變小；海綿組織逐漸消失；葉面結構常為典型旱生結構? ?等葉面；晶細胞及纖維細胞數目增多；輸導組織、機械組織日漸發達；具有維管束鞘等等。 -
Based on the reseaching of lycoris leaf micro - morphology characters by sem scanning, light microscope viewing and using paraffin method in the article, we try to provide the proofs of experiment and the efffective characer indexes to discuss the system and evolution of the lycoris. we find these microscope characers through reseach are as follows : the arrangement type, density and the length of stoma ; the shape and length of the epidermal cells ; the ridge of epidermis ; the transverse shape of leaf ; the number of the vascular bundle ; the style of vessel arrangement of vascular bundle in the middle vein ; the layers of palisade tissue ; the ratio of the thicken of palisade tissue to that of spongy tissue ; the angle number of the middle leaf ; the type of ventilating cavity etc. these characters are different from those of species in lycoris, meanwhile these characters are similar to those of some species in lycoris. so these characters can be used as the character indexes for differentiating species and reseaching systematic evolution of lycoris ; we can divide lycoris into two subgenus by these characteristic indexes : the species of one subgenus are l. aurea ( l " her. ) herb, chinensis traub, l. caldweuii traub, l. anhuiensis y. hsu et q. j. fan, l. longituba y. hsu et q. j. fan ; the species of another subgenu s are l. houdyshelii traub, l. albiflora koidz.,
研究結果表明：葉表皮的氣孔排列方式、長度、長寬比，脊的明顯與否，葉表皮上的顆粒紋飾的多少、大小，葉表皮細胞長度、長寬比、垂周壁形狀，上部葉柵欄組織細胞層數、葉的維管束數、葉中脈導管組成數目，氣腔類型，葉的脊部遠軸面的角數，葉緣的形狀等這些特徵在種間存在差異，同時，在有些種之間又有相似性；因此，這些特徵既可以作為區分種的證據，又是研究石蒜屬植物系統演化的性狀指標，根據這些性狀指標，可以將石蒜屬植物大致分為兩個亞屬：一是忽地笑、中國石蒜、短蕊石蒜、安徽石蒜、長筒石蒜，二是江蘇石蒜、乳白石蒜、石蒜、玫瑰石蒜、稻草石蒜；在兩個亞屬中其中有些種如忽地笑、長筒石蒜、中國石蒜的親緣關系則更近些。 -
For amorpha fruticosa linn., there exists epidermal hair on the upper epidermis, some macro ventilating pit in the spongy tissue, many crystal cells in the phloem of the leaf and around vascular bundles
紫穗槐葉的上表皮有表皮毛，海綿組織局部有大型通氣孔，在葉的主脈韌皮部處和葉柄維管束內外都含有許多含晶細胞。 -
By the compounds of submandibular gland cells and collagen sponges. we investigate the optimal cell denisity of tissue engineered compound of submandibular gland cells and collagen sponges, the cellular compatibility of tissue engineered compound of submandibular gland cells on the collagen sponges with different porosity and the influence of epidermal growth factor on the adherence of submandibular gland cell to collagen sponge. our studies can primary provide theoretical ground work to form the model in vitro of tissue engineering smg
在本研究中，以初步探討體外頜下腺細胞與膠原海綿支架相互作用為目的，採用體外分離培養sd大鼠頜下腺細胞，然後接種于膠原海綿支架上體外復合培養的方法；從不同接種細胞濃度對細胞一支架復合物影響，同一接種細胞濃度在不同孔隙率的支架上黏附、增殖的情況及表皮生長因子（ egf ）對頜下腺細胞的促增殖作用，促細胞在支架上黏附等三方面入手，初步研究了頜下腺細胞與膠原海綿相互作用的影響因素，為進一步在體外及體內構建較為理想的組織工程化頜下腺提供理論參數和實驗依據。
