子孢子体

The primary results could be summarized as follows: The result of flower developing showed that the flower bud morphological differentiation way is form a leaf bud with a flower bud; The process of microspore occurring and male gametocyte development is normal,the development of anther wall is elementeny type.

结果如下：花发育的研究表明，安祖花的花芽分化是以一叶芽一花芽的方式进行；小孢子与雄配子体的发育过程均属于正常发育，花药壁的发育属于基本型，绒毡层细胞属于腺质绒毡层，成熟的花粉粒为2-细胞型。

In contrast,the research of the genetic basis of important economic and stress resistant characteristics of both Laminaria gametophyte and sporophyte is scarce.

然而，海带配子体和孢子体重要经济性状和抗逆性状的遗传基础研究缺乏。

The microsporogenesis and development of male gametophyte in Tsoongiodendron odorum Chun were observed by using the paraffin section method.

采用石蜡切片法对观光木的小孢子发生和雄配子体发育进行了解剖学研究。

The gametophyte is derived from the product of a reduction division in the megaspore mother cell.

该配子体是由大孢子母细胞进行减数分裂而来。

The fern spore, the original cell of the gametophyte, carries out asymmetrical mitosis to produce a large cell and a small cell. The small cell geminates to a rhizoid by tip growth, and the large cell further divides and develops to become a prothallus.

蕨类植物孢子作为配子体的原始细胞，通过不对称的有丝分裂产生一大一小两个细胞，小细胞萌发出极性生长的假根，大细胞继续分裂发育为原叶体。

Comparative studies of embryology of Camellia : sporogenesis andgametogenesis of C.oleifera, C.japonica and C.ptilophylla were watched carefullyunder LM by means of paraffin slides.

山茶属的比较胚胎学研究：通过石蜡切片，用光学显微镜观察油茶、山茶和毛叶茶C.ptilophylla的大小孢子的发生和雌雄配子体的发育；全面总结山茶属的胚胎学资料，从比较胚胎学角度探讨山茶属的系统学问题。

Two culture methods, sterilized MS medium and garden soil medium, were comparatively studied for spore germination of Dryopteris varia, with the observation of its gametophyte development under light microscope.

应用无菌培养和常规泥土培养两种方法对变异鳞毛蕨孢子进行了比较研究，并在光学显微镜下观察了其配子体的发育过程。

Under favorable condition, it multiplies as a unicellular organism. Upon starvation, a pathway involving aggregation, mound, slug, culmination stages induces the formation of a fruiting body consisting of a head of spores supported on a stalk of vacuolated cells.

在营养丰富条件下，以单细胞形式存在；一旦食物匮乏，单个细胞聚集成多细胞体，细胞历经细胞丘、蛞蝓体、拔顶阶段完成发育和分化过程，最终形成由孢子细胞和柄细胞组成的子实体。

The green, filamentous growth that arises from spore germination in liverworts and mosses and eventually gives rise to a mature gametophyte.

原丝体由叶苔或苔藓的孢子萌芽发展而成的绿色丝状生长物，最终发展成配子体

The green,filamentous growth that arises from spore germination in liverworts and moss es and eventually gives rise to a mature gametophyte.

原丝体由叶苔或苔藓的孢子萌芽发展而成的绿色丝状生长物，最终发展成配子体

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
