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.

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

And one with a full set of DNA, called the sporophyte generation because it makes spores.

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

几个小时后,当我忙好城里事情回来时,孢子体仍然在原地,仍然抓着水珠。

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

孢子体长得比苔藓层高很多,使孢子能够传播很远,长出一个群落,一个家庭。

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,视线与藓齐平,向孢子体伸出指尖;但我手停在了半途。

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,在雨后明朗蓝天下,我观察到生长在砖砌围成片螺旋藓孢子囊膨胀到了平时三倍大。

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,细小茎状结构会挠得我发痒。这些茎从苔藓叶中探出来,被称孢子体,每个孢子体末端有一个孢子囊。

Crash Course 植物学篇

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.

最重要是,无籽维管植物——以及在们之后进化所有植物——都有一个显性孢子体,这意味着我们倾向于认植物实际孢子体一代。

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.

拥有一个优势孢子体带来了很多好处——比如,苔藓植物孢体不能长得离地面很远;而无籽维管植物孢子体可以长得更高更大,有更多空间容纳孢器官。
