primordia 解釋
primordium 的復數
  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. It has leaf primordia and a shoot apex.

    它有葉原基和一個苗端。
  3. This is quickly followed by the appearance of the second whorl of stamen primordia.

    接著很快出現了第二輪雄蕊原基。
  4. Thus, transplanting tooth primordia into the jaw to finish developing would seem to be a simple solution

    因此，將牙齒原基移植到頜部繼續發育，看來會是個簡單的解決辦法。
  5. Moreover, tooth primordia must be constructed from the right combination of cells to reproduce natural tooth material and structure

    此外，建構牙齒原基的細胞必須正確組合無誤，才能重現天然牙齒的材質與構造。
  6. In staminate flowers, petal and stamen primordia initiate spirally. evidence from all fields indicates that the relations between acorus and sparganium are distant

    因此，菖蒲屬與香蒲目（黑三棱科、香蒲科）的親緣關系，亦相距較遠。
  7. Primordium ( pl. primodia ) a collection of cells that differentiates into a specialized cell, tissue or organ, e. g. the apical shoot and apical root primordia of the embryo

    原基：指能分化出特化的細胞、組織或器官的少數細胞，如胚芽原基和胚根原基。
  8. Leaf primordia of the as1 - 101 and as2 - 101 mutants grew slowly in comparison to those in wild - type. the as1 and as2 genes expressed with a similar pattern in the wild - type plants

    As1 - 101和as2 - 101的葉原基早期發育異常，而且， as1基因過量表達的植物中普遍存在細胞衰老加快的情況。
