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.

3水稻侧根原基起始具有严格的细胞位置效应，只有与韧皮部极直接相邻的中柱鞘细胞才能分化形成侧根原基。

primordia：原基

小脑蚓部是由两侧半球原基(primordia)在中线融合形成的,先从上部开始,逐渐向下延伸(融合),因此,当有小脑蚓部发育不全时(例如Dandy-Walker畸形),常常只存留小脑蚓部的上部.
