子孢子

Ulva, the sea lettuce in which the alternating generations of the life cycle are morphologically identical.

同形性：在某些具有世代交替生活史的藻类中，其孢子体和配子体形态完全相同的现象。

Most of the endangered plant has the difficulty in sexual reproduction.

大多数的濒危植物都存在有性生殖障碍，通过对珙桐的大小孢子及雌雄配子体形成的研究，发现在这一过程没有异常。

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。

After 3 years of culture, only 3% of the gametophytes produced a sporophyte.

经过三年的培养，只有3%的配子体产生孢子体。

Which are divided into sporophyte developed special-shaped generational and generational shaped gametophytes developed.

其中又分为孢子体发达的异形世代交替和配子体发达的异形世代交替。

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。

Osg6B, a promoter from rice, can direct gene expressing in anther tapetal during the early developmental stage of microspore from tetrad to uninucleate pollen, with high temporal and spatial specificity.

osg6B是来源于水稻花药绒毡层的特异性的启动子，它在小孢子发育的四分体时期至单核花粉期在花药绒毡层中特异启动基因的表达，它具有较为严紧的时空特异性。

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。

There·nectar 310ml, Annona fruit juice 250ml, Lingzhi tea, fruiting bodies of Ganoderma lucidum, Ganoderma lucidum,such as Ganoderma lucidum.

还有番果茶310ml，番果汁250ml，灵芝茶，灵芝子实体，灵芝胶襄，灵芝孢子胶襄等。

Do you know, i need you to come back
