Results of cytological analysis indicated that forming of sporopollenin lamella was defected during pollen development, which leads to abnormal pollen operculum.
细胞学分析的结果显示ms121在花粉壁发育的过程中，萌发孔的孢粉素片层的形成出现异常，导致花粉粒萌发孔的塞子无法正常形成。
In cultivar M-101, the process of tapetal disintegration might be divided into two phases: secreting sporopollenin at microspore developmental stage;
M-101品种花药绒毡层的解体过程大体可分为两个阶段：在小孢子发育期，绒毡层主要分泌孢粉素；
And degrading non-sporopollenin substances at pollen developmental stage.
在花粉发育期，绒毡层主要降解非孢粉素物质。
The events of sporopollenin behavior during the process of tapetal disintegration and their relations to pollen development are discussed.
对绒毡层解体过程孢粉素行为的有关事态及其与花粉发育的关系等问题进行了讨论。
While the number of sporopollenin for two male sterile lines is not significantly changed.
而两不育系中，孢粉素的变化不明显。
Moreover, transmission electron microscopy analysis showed that sporopollenin deposition was abnormal and the mutant pollen exine was irregular.
而且，透射电镜分析结果表明小孢子不能正常沉积孢粉素因而没有规则的外壁结构。
