  1. 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.
    摘要同型孢子蕨类的孢子体可经由同配子体自交、异配子体交配两类配育系统或以无配生殖的方式产生,异配子体交配又可分为异配子体自交和异配子体异交两种方式。

原声例句
Crash Course 植物学篇

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

一种具有全套 DNA,被称为孢子一代,因为它产生孢子。

《卫报》(文章版)

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

几个小时后,当我忙好城里的事情回来时,孢子体仍然在原地,仍然抓着水珠。

《卫报》(文章版)

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,长出一个新的群落,一个新的家庭。

《卫报》(文章版)

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,向孢子体伸出指尖;但我的手停在了半途。

《卫报》(文章版)

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。

《卫报》(文章版)

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出来,被称为孢子体,每个子体的末端有一个孢子囊。

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体,这意味着我们倾向于认为的植物实际上是它的孢子体一代。

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.

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

孢子体sporophyte英语发音:/spɔːrˌft/)是陆生植物与多细胞藻类世代交替过程中的多细胞二倍体阶段。起始于两个单倍体的配子融合(受精)形成单细胞的二倍体的合子。合子再经过有丝分裂形成多细胞的孢子体。蕨类与种子植物的孢子体远远比配子体更为显着与功能完善,孢子体有根、茎、叶的分化。开花植物的配子体(花粉与子房)极端精简到几个细胞。

孢子体通过减数分裂产生单倍体的孢子。孢子再有丝分裂形成单倍体的配子体。成熟的配子体再产生配子。形成世代交替的一个循环。

苔藓 (苔藓植物门, 地钱纲与角苔纲)的配子体比孢子体更为显着与功能完善。其成熟的孢子体依赖于配子体提供营养。

A sporophyte (/spɔːrˌft/) is the diploid multicellular stage in the life cycle of a plant or alga. It develops from the zygote produced when a haploid egg cell is fertilized by a haploid sperm and each sporophyte cell therefore has a double set of chromosomes, one set from each parent. All land plants, and most multicellular algae, have life cycles in which a multicellular diploid sporophyte phase alternates with a multicellular haploid gametophyte phase. In the seed plants, the Gymnosperms and flowering plants (Angiosperms), the sporophyte phase is more prominent than the gametophyte, and is the familiar green plant with its roots, stem, leaves and cones or flowers. In flowering plants the gametophytes are very reduced in size, and are represented by the pollen and the embryo sac.
