antheridium

1. The antheridium is visible 60 days after sowing, pelletlike, consisting of three cells.

原叶体边缘及背腹面都具毛状体，毛状体由单细胞构成。

2. Antheridiogen promotes antheridium and male gametophyte formation.Thus, inter gametophytic mating is more frequent and more successful in those species with high antheridiogen production.

有些蕨类可分泌促精素，有助于藏精器甚或雄性配子体的发生，进而利于异配子体交配的发生。

8. When the gametes are readily distinguished as male or female, other therms may be used such as ANTHERIDIUM, ARCHIEGONUM, or OOGONIUM.

9. It is motile and is produced in an antheridium, except in certain gymnosperms (e.g.Cycas, Ginkgo) in which antherozoids develop from the generative cells of the pollen tube.

除了在一些由花粉管的生殖细胞产生配子的裸子植物中（铁树Cycas,银杏Ginkgo），通常是由精子器产生的并且会游动。
