石蒜屬 的英文怎麼說
中文拼音 [dànsuànzhǔ]
石蒜屬
英文
lycoris-
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。The classification system among species of lycoris was discussed through morphology, chromosome, molecule. the systematical relationship among 12 species of lycoris has been discussed. the problems in the taxonomical systematics are as follows : ( l ) the results of cytology are different from that of molecule, but results of karyotype analycis and that of rapd are same. so it is seem too hard to divide lycoris two subgenus according to corolla regularity
其中，通過形態、染色體、分子方面對石蒜屬植物種間分類系統進行了探討，在石蒜屬分類系統方面存在的主要問題有： （ 1 ）細胞學與分子系統學上的證據較為一致，而與形態學上的證據存在差異，因此，能否以花冠整齊與否將石蒜屬劃分為兩大亞屬值得商榷； （ 2 ）石蒜屬植物的雜合體較多，這些種的系統位置仍存在分歧； （ 3 ）微形態證據探討石蒜屬分類系統方面研究較為缺乏。In the first, the research development and problems in the taxonomical systematics of lycoris were summarized in the article, including the research of germplasma resources and exploitations, artificial cultivation, tissue culture, physiology, morphology, pharmacology, decorative values and molecule
本文首先綜述了石蒜屬植物的研究進展及分類系統學上存在的問題，包括石蒜屬種質資源的開發利用、人工栽培和組織培養、生理、形態、染色體、藥用和藥理、觀賞價值以及分子方面的研究。( 3 ) the research of lycoris on the systematical relationship of micro - morphology and anatomy is absent. it is essential to generalize the character inde xes of morphology, anatomy, cytology, palynology and molecular physiology. so we can establish classification system of lycoris and draw a reasonable family tree of lycoris
因此，必須綜合形態學、解剖學、細胞學、孢粉學和分子生物學等各方面的性狀指標，才能夠建立更合理的石蒜屬植物分類系統，並繪制出完整的石蒜屬分支系統樹。分享友人
