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。
