查询词典 female gametophyte

Sinense, the spores germinate inside their exospores and then divide into massive protonemata;the massive protonemata can form two kinds of protonemata of which one is clubbed protonema with papillae,and the other is caulonema composed of long and cylindrical cells ; the gametophyte archaeocytes only occur on the massive protonemata.

结果表明：中华缩叶藓的孢子在壁内萌发，随后分裂产生块状原丝体；块状原丝体上可产生两种丝状体，一种是具疣的棒状原丝体，另一种是由长圆柱状细胞组成的轴丝体；配子体原始细胞只产生于块状原丝体上。

Rhizoid A unicellular rootlike structure found in certain algae and in the gametophyte generation of the bryophytes and some ferns.

假根：在一些藻类、苔藓植物和裸子植物配子体中存在的由单个细胞形成的类似根的结构。

In addition, the results of male gametophytic selection would be effect the phenotype of offspring in sporophyte due to about two-thirds of gene expression proceed during the growth stage of gametophyte and sporophyte.

此外，由于植物基因组中约有2/3的基因表达交错发生在配子体阶段和孢子体阶段，因此雄配子体选择的结果会影响到下一代孢子体的表现型。

The development of a gametophyte directly from a sporophyte without the occurrence of meiosis or spore formation.

无孢子形成，无孢子生殖，无孢子状态没有经过减数分裂或孢子形成而直接由孢子体进行的配子体发育

The gametophyte development of the two species were observed morphologically. Spore germination rates and sporophyte appearance rates in various culture media and substrate were also studied.

falcata 的孢子，对其配子体发育过程进行形态学观察，研究不同培养基中孢子的萌发率及成苗情况。

It took a minimum of 13 months after a spore sowing for a sporophyte to be produced by a gametophyte. Increasing the wild population will likely be slow and difficult.

由於孢子体的生成至少需13个月，以及其低生成率，可能导致其野外族群之扩增极为缓慢且困难。

The results showed that the techniques could increase gametophyte adhesion rate by over 80%, made the seedlings stronger and the germination quality reach state standard of Class Ⅰ. The growth speed of clone adhesion (8~16 rows) was about 20 days faster than that of normal sporophyte seedling adhesion.

结果显示，这样的措施可使配子体附着率达到80%以上、幼苗健壮、出苗质量达到国家一类帘标准，使克隆采苗自8～16列c期间的生长发育速度较常规孢子体采苗后的生长发育速度快20 d。

In the Filicinophyta, Sphenophyta, and Lyophyta the embryo sporophyte produces a footlike structure that remains embedded in the tissues of the parent gametophyte plant, absorbing nutrients like the suspensor of higher plants.

在真蕨门 filicinophyta ，楔叶门 sphenophyta，和石松门 lycophyta 中，胚胎孢子体产生足状结构，仍然包裹于双亲配子体植物内。胚胎吸收营养的方式同高等植物从胚柄那样吸收营养一样。

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。

This article mainly discusses the large-scaled cultural conditions of clone in Gametophyte Laminaria .It studies the proper temperature, light time, light intensity, the consumption of nitrogen and phosphorus, the cultural state and inoculating density on the growth of gametophytic clone, the experiment of large-scaled culture had been done under comparatively proper conditions, in the same time, we studied the growth rule of gametophytic clone in the cultural process.

本文主要探讨了海带配子体克隆的大规模培养条件，对海带配子体克隆生长的适宜温度、光照时间、光照强度、营养盐消耗、培养状态以及接种密度进行了研究，并在相对适宜条件下进行了大规模培养实验，同时，对海带配子体克隆在培养过程中的生长规律进行了研究。

The use of the web to spread fears that flicking the switch on the LHC could create a Black Hole that could swallow up the Earth particularly concerned him, he said.

他说，使用互联网散布恐慌说启动LHC会生成一个可能吞噬地球的黑洞的做法让他感到忧虑。

Not a single word have I written down.

我一个字也没有写下来。
