鬱金香屬 的英文怎麼說
中文拼音 [yùjīnxiāngzhǔ]
鬱金香屬
英文
tulipa-
Illiensis type and t. tetraphylla type. there are more than one types of embryo sac in 3 species, sush as t. illiensis, t. heteropetala and t. heterophylla
在所報道的5組共45種鬱金香屬植物中，發現該屬植物的胚囊發育類型具有一定的系統學意義。The morphological characteristics are recognized as 3 types : nearly globe, nearly boat shape and nearly shield shape. the exine ornamentation can be divided into 5 types : reticulate, steiate - veticulate, tuberculate, verrucate and rugose - sinuate. the morphological characteristics show some vaviations among sections and species in terms of the shape of pollen and the exine ornamentation. and thus can be used as one of characters in the consideration of the classification of this genus. ( 4 ) the micromorphology of the seed coats were observed in 13 species
（ 4 ）所觀察的該屬13種植物的種皮表面紋飾可分為網紋、負網紋和皺波狀三大類，且各個種之間在種皮微形態上均存在著一定差異，可以作為分種的依據；在組間，除屬于有苞組（ sect . amana ）的t . edulis和其它組的種類有明顯差異外，其餘3組之間沒有明顯的界限，說明鬱金香屬的種皮微形態特徵在組的劃分上意義不大，但在種的劃分上具有一定的分類學意義。In this paper, the taxonomical problems of tulipa l. from china were studied based on the results of both the field observation and the examination of herbarium specimens, and the analysis of leaf epidermis morphology, pollen morphology, seed coats micromorphology and comparative embryology. the main results are as follows : ( 1 ) tulipa l. from china is taxonomically revised. there are 16 species distrubuted in china and tulipa kuocangshanica d. y. tan, x. r. li et d. y. hong is described as new
本文通過野外調查及憑證標本的考證，並結合葉表皮形態、花粉、種皮的微形態及比較胚胎學等方面的觀察，對國產鬱金香屬植物分類中存在的問題進行了研究，主要內容如下： （ 1 ）對國產鬱金香屬植物進行了了修訂，確認了國產鬱金香屬植物共有16種，其中新種1個: tulipakuocangshanicad . y . tanx . r . lietd . y . hong 。( 2 ) the morphological characteristics of leaf epidermis of 16 species were studied. the results show that the morphological characteristics of leaf epidermis have not obvious differences among sections except sect. amana, but there are some differences between species, and indicate that the morphological characteristics of leaf epidermis have some value for the interspecific classification
（ 2 ）對國產4組16種鬱金香植物葉上下表皮的形態學觀察，發現葉表皮形態在種間均存在一定程度的差異，但在組間，除了有苞組的4個種與其它種類有明顯差異外，其餘3組間沒有明顯的差異，表明鬱金香屬植物的葉表皮特徵在種級水平上具有一定的分類學意義，可以作為種的劃分及種間親緣關系探討的參考指標之一。分享友人
