tepal 解釋
花被片
  1. In this paper the floral ontogeny and the ovary development of rivina humilis l. were observed. the results showed that ( 1 ) the tepal primordia initiated in 2 / 5 spirals. the abaxial one initiated first, then the adaxial one, finally the lateral two initiated nearly simultaneously. the third one initiated on the position near the first tepal, and there is a gap between itself and the second tepal. ( 2 ) the 4 stamineal primordia initiated in one whorl at the same time. ( 3 ) the carpellary primordium initiated from the abaxial side of flower primordium ; the carpellary primordium grew upwards and towards axis after it was formed, therefore an elliptic orifice was formed at the adaxial position of ovary, which was the remainder of the mouth of ovary before the ovary was fused completely. with the ovary maturing, the orifice was narrowed because of the ovary growth, at last fused completely. the gynoecium is composed of a single carpel. ( 4 ) in the series developmental sections of ovary, the ovular primordium was initiated on the adaxial meristem when the mouth of ovary was formed

    對數珠珊瑚的花器官發生和子房的發育過程進行了觀察.結果表明: ( 1 )數珠珊瑚花被呈2 / 5螺旋狀發生,遠軸側的1枚先發生,其次為近軸側的1枚發生,最後側方的2枚花被幾乎同時發生,第3枚花被在靠近第1枚的位置發生,第2枚和第3枚之間有1個空隙; ( 2 ) 4枚雄蕊是同時發生的; ( 3 )心皮發生於分生組織的遠軸側,心皮原基形成后,向上向軸生長,在子房成熟前在近軸側非正中位形成1個孔,該孔為心皮最終愈合前的殘跡,到子房成熟時,因子房的生長孔被擠壓縮小,在進一步的生長過程中愈合.子房由1枚心皮構成; ( 4 )從子房發育過程的切片看,該植物的胚珠是在子房發生后不久發生的,子房上的圓孔形成時,從近軸側的分生組織發生胚珠原基,由胚珠原基分化出珠被與珠心
  2. The results from rapd and sequence analysis did not support sectional treatments of the subgenus yulania based on sepaloid tepals, time of flowering, and the tepal color

    表明因地理隔離形成染色體水平上的不同要遠遠大於形態上的差異,不支持前人單純依據形態特徵進行的分組處理。
  3. The evolutional trends of the twig, leaf, florescence, tepal and fruits were discussed. 2. anatomy of both leaf and lemma epidermis micro - morphological characters of leaf epiderm is of 11 species and 1 varities of machilus distribute in zhejiang were examined by lm and sem

    葉片表皮結構在光鏡和電鏡下觀察潤楠屬植物葉表皮結構,結果表明:上表皮無氣孔器,表皮細胞(表面觀)的垂周壁式樣由平直、淺波狀和深波狀變化。
  4. The main results are summarized as follow : 1. gross morphology on the basis of field observation and examimation of herbarium specimens, the variation pattern of all the major gross - morphology characters in machilus from zhejiang was studied, and their taxonomic significance was evaluated. the results show that the most reliable characters for the delimitation of species are the features of the leaf, the tepal and the fruits. the secondly important characters are the length and position of the florescence

    形態性狀分析分析結果表明:潤楠屬植物的分類性狀主要有小枝、葉片、花序、花被片、果實等特徵特性,其中花被片、葉片、果實是潤楠屬的重要分類性狀;花序的長度及著生位置也是區分潤楠屬種間的重要標志之一;小枝的毛被在分類上具有第三位的重要性。
