孢子体

In plants that undergo ALTERNATION OF GENERATIONS, spores are produced by meiosis by the sporophyte generation, so are usually haploid; they germinate to produce the haploid gametophyte generation.

在具有世代交替的植物体中，由孢子体世代进行减数分裂产生孢子，因此多为单倍体。它们将发育为单倍体的配子体世代。

Archesporium The single cell or group of plant cells in the sporophyte from which spore mother cells may eventually develop in a sporangium.

archesporium 孢原细胞：植物孢子体中的单个细胞或单组细胞。在那里孢子母细胞最终发育为孢子囊。

Sporophyte The diploid generation in the life cycle of a plant, which gives rise asexually to haploid spores.

孢子体：植物生活周期的二倍体世代。无性生殖可产生单倍体的孢子。

A prefix is often added, providing information as to the nature of the spore, for example conidiospores arise on a conidium, megaspores and microspores are the larger and smaller spores produced by heterosporous plants, etc.

此词前常有前缀修饰，用以提供含孢子特征的信息。例如 conidiospores 源于分生孢子， megaspores 和 microspores 是大孢子和小孢子，由具异型孢子体的植物体产生。

In vascular plants, the sporophyte is the dominant generation, while in bryophytes it is parasitic on the gametophyte.

维管植物以孢子体世代为主，而在苔藓植物的孢子体寄生在配子体上。

In theterosporous species, a distinction is usually made between megaspore mother cells and microspore mother cells.

在异型孢子体种类中，可区分为大孢子母细胞和小孢子母细胞。

After 13 months culture, sporophytes began to form. Each gametophyte had several archegonia, and only one sporophyte was produced per gametophyte. The first sporophyte frond was simple and had pinnate venation.

抱子体在经13个月的培养后开始产生，每个配子体虽然有许多的藏卵器，但只产生一株孢子体，第一片孢子体的叶片为单叶羽状脉。

Epiphytic bacteria were isolated from sporophytic thallus collected from Qingdao and Dalian or gametophytic filaments stored in our lab of Laminaria japonica. Identification was done using both traditional physiological and biochemical way and molecular method. Phylogeny tree was established based on 16S rRNA gene sequence analyses, and some sequences of epiphytic strains from both sporophyte and gametophyte were different from all the sequences already exit and could be the new species.

采用生理生化和16S rRNA基因序列比对的方法对从两个海区采集的海带孢子体以及实验室中保存的海带配子体样品的外生菌分别进行组成分析，16S rRNA基因序列揭示了在海带孢子体和配子体的外生菌中都存在一些与现有数据库中序列的遗传关系较远的菌株。

In filicophytes, there was a relatively high ratio of VA mycotrophy in the eusporangiates, and there was no autotrophic in the eusporangiates; but the ratio of autotrophic was up to 71%, and the ratioes of VA mycotrophic and facultative mycotrophic were low, 15% and 14% respectively in the leptosporangiates.

用碱解离、酸性品红染色法对云南热带、亚热带自然生长和部分移栽到温室中的256种（拟蕨类植物20种，真蕨类植物236种）蕨类植物孢子体的VA菌根状况进行了调查研究，结果发现，在拟蕨类植物中，孢子体只存在兼性VA菌根营养和自养两种菌根营养类型，两种类型，两种类型所占的比例相当；在真蕨类植物中，厚囊蕨类植物VA菌根营养的比例较高（92%），且无自养类型；而在薄囊蕨类植物中，自养型占71%，VA菌根营养和兼性菌根营养所占的比例都不高，分别是15%和14%。

Japonica and 1.3 cm of U.pinnatifida which showed heterosis in growth during the temporarily sea cultivaton. The phenotypic character of F_1 juvenile sporophyte of L.japonica♀×U.pinnatifida♂was similar to that of the female parent, namely, L.japonica which generated no rudiments of the pinnate lobations.

海带♀×裙带菜♂杂交组合的受精率为20-33%，在暂养期间F_1幼孢子体达到2.2 cm，大于海带、裙带菜幼孢子体的1.8 cm和1.1 cm，表现出生长优势；F_1幼孢子体表现出母本海带的性状，无裂叶缺刻雏形的形成。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.

主要做了如下几个方面的工作：对伸臂位于顶部的单层框架—筒体模型进行分析，提出了等效转动约束的概念和转动约束刚度的表达式。

Male cats normally do not need aftercare with the exception of the night after the anesthetic.

男猫通常不需要善后除了晚上的麻醉。
