Homosporous ferns produce sporophytes by intra gametophytic selfing, inter gametophytic mating, or apogamy.Gametangium ontogeny, genetic load, and ploidy affect the mating system of each species.

型孢蕨类的孢体可经由体自交、异配体交配两类配育系无配生殖的方式产生,异配体交配又可分为异配体自交和异配体异交两种方式。

Hours later, when I returned from my chores in the city, the sporophytes were still there, still holding water.

The sporophytes grow considerably taller than the bed, to allow the spores to travel far and start a new commune, a new family.

孢子长得比苔藓层高很多,使孢子能够传播很远,长一个的群落,一个的家庭。

Down on my knees, at eye level with the bed, I reached out with a fingertip towards a sporophyte, but my hand stopped itself midway.

我双膝跪地,视线与墙藓齐平,向孢子指尖;但我的手停在了半途。

One day, under a bright blue after-rain sky, I observed that the sporophyte capsules of a wall screw-moss bed growing on a brick fence had swelled to almost three times their usual size.

某天,在雨后的明朗蓝天下,我观察到生长在砖砌围墙上的成片墙螺旋藓的孢子囊膨胀到了平时的三倍大。

As I carefully brush the backs of my fingers against moss beds, tiny stalk-like beings tickle me. Jutting out of moss leaves, these stalks are known as sporophytes; each sporophyte contains a capsule of spores at its outermost end.

当我小心翼翼地用手指背面扫过苔藓时,细小的茎状结构会挠得我发痒。这些茎从苔藓叶中探来,被称为孢子,每个孢子的末端有一个孢子囊。

On top of that, seedless vascular plants — and all plants that evolved after them — have a dominant sporophyte, meaning that what we tend to recognize as the plant is actually its sporophyte generation.

最重要的是,无籽维管植物——以及在它们之后进化的所有植物——都有一个显性的孢子,这意味着我们倾向于认为的植物实际上是它的孢子一代。

Crash Course 植物学篇

Having a dominant sporophyte introduced lots of advantages — like, while the spore-making generation of a bryophyte couldn't grow very far off the ground; the sporophytes of seedless vascular plants could grow much taller and larger, with more room for spore-producing organs.

拥有一个优势孢子带来了很多好处——比如,苔藓植物的产孢不能长得离地面很远;而无籽维管植物的孢子可以长得更高更大,有更多的空间容纳产孢器官。
