These results revealed that the pollen chamber developmental pattern passed through four phases. Firstly, a group of nucellar cells at the micropylar end elongated longitudinally. Thereafter, the uppermost nucellar cells at the micropylar end initiated PCD; and these elongated cells undergoed PCD in a basally and laterally oriented direction to form a cavity.
贮粉室的形态发生可分为4个阶段:最先是位于珠孔端的几层珠心细胞纵向地伸长;接着,珠孔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,珠孔端的珠心表皮细胞发生开裂,形成贮粉室的开口。
