The results are as follows: Allium odorum-type& Callose first occurs in the wall of megasporocyte from the micropylar end, then gradually envelops the whole cell. Megasporocyte is surrounded by the wall with callose during metaphase ⅰ, anaphase ⅰ and telephase ⅰ.
结果表明,韭型(Allium odorum-type)胚囊大孢子发生时,自大孢子母细胞的珠孔端细胞壁内出现胼胝质荧光,并逐渐扩展到整个细胞壁,中期Ⅰ至末期Ⅰ细胞壁呈现胼胝质荧光。
