The first split of microspore mother cell is observed after one week after beginning of temperature arised under high temperature but the split of secondary sporogenous cell doesn't be found.

Moreover, the extremely slow development of gametophyte and time interval between the appearance of antheridia and archegonia resulting from the inherent physiochemical property of red soil make it impossible to fertilize and generate sporophyte.

此外，红壤固有的理化性质导致扇蕨配子体发育极其缓慢、精子器和颈卵器发生的时间间隔过长使其不能受精产生于包子体。

In the Coniferophyta the female gametophyte is reduced to a nonphotosynthetic tissue with up to 2000 nuclei in the ovule, which produces archegonia.
