贮粉室的形态发生可分为4个阶段:最先是位于珠端的几层珠心细胞纵向地伸长;接着,珠端最顶部的珠心细胞发生PCD;然后,那些已经纵向伸长的珠心细胞向基地和侧向地依次发生死亡,产生贮粉室空腔;最后,珠端的珠心表皮细胞发生开裂,形成贮粉室的开口。

As our studies showed, silylation of mesoporous molecular sieves with alkoxysilane was an usual method of linking desired organical groups. However, as a result, the a lot of silanol groups still existed on the surface of mosoporous molecular sieves after silylation, which maybe affect the interface property and its catalystic activity. Based on this consideration, a novel method was proposed that a mixture of trichlorosilanes was used to silylate mesoporous molecular sieves, introducing both the further reactive group and hyhrophobic methyl group in one pot.
