选用成熟的蕨菜孢子播种于基质为母土的培养皿中，观察其生长进程及配子体、幼孢子体的生长速度发现，受精早晚与配子体大小没有直接的关系，而与配子体成熟度即精卵器产生早晚密切相关；受精后配子体（原叶体）由大变小，由绿变黄，由厚变薄，最后死亡，但死亡早晚个体间存在明显差异。 The mature Bracken spores were sown in Petri dishes, and the growth process and the growth of gametophyte and juvenile sporophyte were observed. There was no direct relationship between the fertilization rate and gametophyte size, but with gametophyte maturity Sooner or later, the gametophyte (former leaf body) after fertilization was changed from big to small, from green to yellow, from thick to thin, and finally died, but there was a significant difference between morning and evening death.
