Before anthesis wall of egg apparatus is complete ; most part of egg wall at the chalazal end disappears at the day of anthesis ; after frtilization ( 20h after pollinating ) egg wall becomes intact . the results suggest that rebuilding of wall is one of the early cytological events during fertilization 结果表明，开花前蓝猪耳的卵细胞的胞壁是完整的；开花时胚囊已发育成熟，此时卵细胞在合点端部分区域是裸的；受精后(大约授粉后20小时)卵细胞的胞壁恢复完整。

It was also found that the nuclear envelope disappeared earlier at the micropylar end than that at the chalazal end . the speed of the programmed cell death were different in three nonfunctional megaspores at the micropylar end and their relationships with the neighboring cells were also different . the biological significance was discussed about these phenomenon 还发现了大孢子母细胞合点端的核膜先于珠孔端的消失，并且珠孔端3个大孢子的死亡时间不同，与相邻细胞的关系也不同，进而讨论了这些现象的生物学意义。
