配子体

This article summarizes the culture of clone study in gametophyte Lami naria, and its application to idioplasm resources and the production of breedin g and seeding.

综述了有关海带配子体克隆研究进展以及在种质资源和苗种生产中的应用情况。

In these groups and in the bryophytes, some species produce unisexual gametophytes and some produce hermaphrodite gametophytes.

这些类群以及苔藓植物中的某些种类的配子体属于雌雄异株，而另外一些则为雌雄同株。

Homospory The production of only one kind of asexual spore, which then develops into a hermaphrodite gametophyte, in the vascular plants the condition is seen in most ferns, psilophytes, and Lycopodium species.

孢子同型：是只产生一种无性孢子并发育为雌雄同体配子体的现象。在维管植物中，很多蕨类，裸蕨和石松属的植物中常见。

Then took calli of Physcomitrella patens on the media plus different plant hormones, normal gametophyte of Physcomitrella patens were differentiated in medium Knop.

诱导愈伤组织分化的实验结果表明：未添加任何植物激素的Knop培养基上分化出正常的配子体且数量最多。

Ten or more archegoniums occurred at the edge of megagametophyte, and the egg was found after two mitosises.

十多个颈卵器在同一个成熟雌配子体上发生，两次有丝分裂后，形成卵细胞。

Although the megagametophyte formed and even the double fertilization had been finished 70 days after pollination at normal temperature, the megasporogenesis had not yet been finished at low temperature.

低温(12-18℃)处理的蝴蝶兰，授粉50d开始分化胚珠原基、60 d胚囊处于大孢子母细胞时期，比常温(20-25℃)下的推迟10-15 d；授粉70 d，常温下的蝴蝶兰植株已完成雌配子体发育和双受精，而低温处理的蝴蝶兰仍未完成大孢子的发生过程。

Mature embryo sac can form from megaspore mother cell on the modified VW medium supplemented with 0.5mg/L BA and 0.1 mg/L NAA.

在培养基无外源激素或仅含生长素或细胞分裂素时，雌配子体的发生过程不能顺利完成；在改良VW培养基上添加0.5 mg/L BA和0.1 mg/LNAA时，形成成熟胚囊。

Methods MSK-2 and MS mediums were used to induce gametophyte into callus tissues, and fuzzy comprehensive evaluation method was used to assess the optimal phytohormone combination.

方法用MSK2和MS培养基对地钱配子体进行愈伤组织诱导，运用模糊评判对MSK-2培养基生长激素组合进行综合性状评价。

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。

Although gametophytic self-incompatibility functions can ultimately prevent self-fertilization , flowering plants have adopted different signal transduction pathways to reject self pollen .

配子体SI植物虽然都具有其SI的功能而阻止自我受精，但它们采取的信号转导途径是不同的。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
