The floral primordium is initially circular, along with the edge of which slight concaves occur. The outmost whorl of tepal primordia arises as a result of apical meristem division and the floral primordium then is in the shape of triangle. Two further whorls of tepal primordia arise in spiral acropetal sequence and are alternately arranged. When the innermost whorl of tepal primordia is at the late developmental stage, the foremost stamen primordia arise almost simultaneously in spiral acropetal succession and all of the stamen primordia are ultimately arranged in a triangle-cone form. Late in stamen primordium development, carpel primordia arise as same as the young stamen primordia and grow laterally. Grooves are present on the adaxial side of each carpel and develop into ventral sutures gradually closing up.

观光木的花原基最初为近圆形,随着顶端分生组织的活动,花原基边缘处出现浅凹,形成第一轮花被片原基,此时,花原基呈三角形排列,后两轮花被片原基依次发生,与前一轮互生;在内轮花被片发生的后期,最初几枚雄蕊原基几乎同时出现,呈螺旋状向顶发生,最后排列成三角圆锥状;雄蕊原基发育后期,心皮原基开始发育,形状与发育初期的雄蕊原基相似,随后心皮原基进行侧向生长,在近轴面出现浅凹,进而发育为凹槽,形成腹缝线,最后腹缝线完全愈合。

The morphogenesis of floral organs in both srg mutant and wild-type rice Dular (Oryza sativa L.) was observed using the scanning electron microscope. The results showed that the floral primordia were differentiated under irregular pattern in srg mutant. After regular formation of lemma and palea primordia, the floral primordium of srg formed lodicule primordia inner to both lemma and palea, followed by the formation of stamens and carpel. Alternatively, floral primordia in srg were split to form two or more floral primordia. The number and position of stamens and carpels primordia were malformed.

利用扫描电子显微镜观察野生型水稻和裂颖水稻的颖花原基分化情况,结果发现,突变体水稻的幼穗在形成内、外稃原基后,有些颖花在形成浆片后并不是直接发育形成雄蕊原基,而是在外稃或内稃原基内侧又分化出浆片原基;有些颖花原基从中间缢裂,缢裂的颖花原基又分别形成类稃片的结构,颖花发育后期,6枚雄蕊发育畸形,并且观察到不同数目的雄蕊。

Rice lateral root primordia initiated only from the pericycle cells adjacent to the phloem poles, indicating that initiation of rice lateral root primordia had specific cell type pattern.

The short shoot differentiation came from the lateral buds among the bud scales, in the initial stage, the lateral buds elongating, and then differentiating two "anisomerous"(one was small, the other was big) needle primordia in the elongating courses; the big one differentiating once more, and formed three needle primordia.

短枝的发育来源于长枝上芽鳞间的侧芽,在发育的初期,侧芽进行伸长生长,在伸长生长的过程中首先分化出一大一小&不对称&的两个针叶原基,大的叶原基进一步分化,形成三个针叶原基。

The results are as below: 1. In Brasenia, 3 sepal primordia and 3 petal primordia initiated stimultaneously in each whorl. The first six stamen primordial initiated in a whorl stimultaneously, and the succeedings ones initiated in irregular spirals. Ascidiate carpel numerous, initiated in spirals.

结果表明: 1。莼菜的萼片和花瓣各3枚,都为轮状同时发生;雄蕊多数,除最早发生的6枚雄蕊原基为轮状同时发生外,其余均为螺旋状向心式发生;心皮多数,螺旋状向心式发生,为囊状型心皮。

The number of leaf primordia was affected by both genotype and environment, while the numbers of bracteal, spikelet and floret primordia were affected mainly by environmental factors.

以平均热间距来衡量,适期播种处理的叶片、苞叶和小穗原基分化速率最高;而小花原基数与小花分化持续期之间的数量关系最为密切。

The floral morphogenesis of Coptis was observed under scanning electron microscopy. The initiation of all floral organs of the genus is spiral, the petal primordia are slightly retarded, the developmental sequence of the stamens is centripetal,the carpel primordia are conduplicate (i.e., horse-shoe shaped), the ovaries are half closed and the ovary stalk is formed in the developmental process.

本文运用扫锚电子显微镜观察了黄连属植物花的形态发生和发育过程,结果表明,该属植物所有的花部器官均为螺旋状发生,雄蕊为向心式发育,花瓣原基有微弱的延迟发育,心皮原基为对折型,子房为半封闭类型,子房柄是在发育过程中形成的。

The results showed that OsMADS8/7 transcripts are first detected in branching primordia, then in spikelet meristem primordia.

The observation of morphogenesis of flower buds in this stage shows that this early floral buds have only perianth primordia at most, and no sex organ primordia yet.

综上所说,黄瓜的性别表达过程应该是多激素共同作用的结果,并且每一种内源植物生长物质对黄瓜性别表达的作用应该有一定的阈值。

On the floral apex the different classes of organ primordia appeared in the following sequence: calyx, corolla, androecium and gynoecium, and they had overlapped with each other when occurring in turn.

花原基分化形成花的整个过程符合一般的分化顺序:花萼原基-花冠原基-雄蕊原基-雌蕊原基,且各原基在分化顺序上存在交叉。
