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。 -
White star and scale - shaped hair is dense on the surface of elaeagnus angusti folia " s leaf, and stoma distribution is mostly irregular
沙棗葉表面具密集的白色星形鱗片狀毛，氣孔分佈多呈不規則型。 -
The results showed that the differences of leaf thickness, cutin layer thickness, stockade tissue thickness, sponge tissue thickness, ratio of stockade tissue thickness to sponge tissue thickness, tightness of leaf tissue structure, sedimentation of leaf tissue structure and stoma density were significant, while the differences of the sizes of upper epidermis and lower epidermis were not
葉片厚度、角質層厚度、柵欄組織厚度、柵欄組織與海綿組織厚度的比值、葉片結構緊密度和氣孔密度等值越大的含笑，受旱危害愈輕，其抗旱性就越強。 -
The trees with thick cutin layer, high stoma density, thick stockade tissue, high ratio of stockade tissue thickness to sponge tissue thickness, and high sedimentation of leaf tissue structure are of greater drought resistance
葉片厚度、尤其是角質層的厚度和海綿組織厚度是評價供試含笑抗旱性的重要解剖指標。 -
This paper presents the mechanism research on the decontamination of air pollution by plants in recent years, mainly including the following : absorption and sorption of stoma and cuticle on leaf surface, plant metabolism and enzyme redox, and degradation by plant in combination with bacteria in root
摘要介紹了植物去除空氣污染物的研究現狀及機理，主要包括：通過葉表面的氣孔和表皮吸收、吸附；植物體內代謝或者分泌酶催化氧化還原進人體內的污染物；通過植物聯合根系微生物降解由於干濕沉降進人土壤或者水體中的污染物等。
