孢粉素

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；

In cultivar M-101 , the process of tapetal disintegration might be divided into two phases : secreting sporopollenin at microspore developmental stage ;

在花粉发育期，绒毡层主要降解非孢粉素物质。

And degrading non - sporopollenin substances at pollen developmental stage .

利用派罗宁B-黄色组分诱导孢粉素产生荧光的特异性，观察了水稻M101品种以及它的无花粉型胞核雄性不育（GMS）突变体Ⅰ-15系花药绒毡层解体过程中孢粉素的行为。

Sporopollenin behavior during the process of tapetal disintegration of rice cultivar M-101 and its induced genetic male sterile ( GMS ) no pollen mutant , line ⅰ - 15 , was observed by using the yellow fraction of pyronin B to specifically induce the sporopollenin to fluoresce .

而两不育系中，孢粉素的变化不明显。

While the number of sporopollenin for two male sterile lines is not significantly changed .

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。

Moreover , transmission electron microscopy analysis showed that sporopollenin deposition was abnormal and the mutant pollen exine was irregular .

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。

The events of sporopollenin behavior during the process of tapetal disintegration and their relations to pollen development are discussed .

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。

Results of cytological analysis indicated that forming of sporopollenin lamella was defected during pollen development , which leads to abnormal pollen operculum .

干酪根主要是母源体中的孢粉素与木质素在埋藏环境中不同热变质阶段的残留物，是油气形成的母源物。

Kerogen is the leftover material of sporopollen element and lignin in original bodies in different thermal metamorphic period and it is the original material of gas-oil formation .

油气形成是多源的，探讨了中国各时代油气形成主要母源体。这些母源体中富含形成油气的主要母质即孢粉素与木质素。

Gas-oil formation is multi-original . Authors discussed the main original bodies of gas-oil formation in different stages in China , which enrich main mother material of gas-oil formation named sporopollen element and lignin .

不育株小孢子发生和发育过程中胼胝质的异常和小孢子缺乏孢粉素是引起小孢子囊败育的原因之一。

It is suggested that the abnormality of callose wall and short of spro pollenin in the male sterile plant during the genesis and development of the microspore are the main reasons for abortion of microsporangium .
