子囊

The anther possesses four microsparangia with its wall composed of four layers: epidermis, endothecium, middle layers and a 2\|nucleate celled tapetum.

绒毡层细胞在发育后期由单核分裂为2 核，多原位解体，为腺质型；但大约有12％小孢子囊的绒毡层在小孢子四分体释放时期进入花药室内，成为变形绒毡层。

Hsüopsida is parallel to the above three plant categories in Early Devonian and differs from them in that: the trimerophytes or Euphyllophytina have long fusiform sporangia terminating in trusses and P-type tracheids; the zosterophytes or Lycophytina are characterized by the exarch xylem; the rhyniophytes bear simple isotomous branches and S-type tracheids.

徐氏蕨类群与上述早泥盆世的三大类群并行，它不同于三枝蕨类或者是真叶植物的长纺锤形、成簇顶生的孢子囊和P-型管胞；不同于工蕨类或石松植物的外始式木质部；不同于莱尼蕨类植物简单的等二叉分枝和S-型管胞。

The study data would lay an important foundation for further development of new breeding technology used for free-living conchosporangia.

以上研究为实现紫菜细胞工程育苗新技术－自由壳孢子囊枝育苗奠定了坚实基础。

Eurotium is a member of eurotiales, and is teleomorph of aspergillus glaucus group. nineteen species have been accepted, and some of them could produce mycotoxin, and most of them are abundant in producing of the pigments and the second metabolites.

eurotium为eurotiales之一重要成员，目前已知有19个种，其无性世代为aspergillus glaucus group.eurotium中有些种会产生真菌毒素，大多数种可产生丰富的二次代谢产物及色素。eurotium具有耐渗透压之特性，於适当培养下会行成子囊果。

Tuber formosanum is an endemic truffle and symbiosed on Cycobalanopsis glauca of Taiwan. Tuber indicum is a widespread truffle species in Yuannan and Szchuan province in China. The external morphology and gleba of ascocarps are very similar to T. formosanum and T. indicum.

台湾块菌是台湾原生块菌与青刚栎共生之菌种，印度块菌是中国云南、四川地区广泛分布之菌种，2种块菌子囊果在外部形态及产孢组织颇相似。

Recurvata occurred in the Posongchong Formation of Zhichang Section, Wenshan District. Detailed research shows that Huia gracilis sp. nov. has K- or H-type branching in the rhizome.

茎轴光滑，二叉分枝，直立的长楔形孢子囊侧生，松散螺旋排列，具长柄，由较小的近轴瓣和较大的远轴瓣组成，两瓣凹凸，开裂缝具明显的边缘加厚带。

E The indusium is a structure that protects sporangia in true ferns.

真蕨中的孢膜是保护孢子囊的构造

Sori 1-5 pairs borne on the lower surface of ultimate lobes at the end of basal veins; indusium dehiscent in two equal halves when mature.

孢子囊群1-5对，生於末回裂片下面近基部小脉顶端；囊群盖成熟时对开2裂。

Sori borne on the basal segments of the pinnules, indusium cylindrical, mouth hardly dilated and lobed; receptacle protruding, curved, dark brown.

孢子囊群生於小羽片的基部裂片上；囊群盖筒状，口部几不扩大和分裂；囊群托长而突出，弯曲，黑褐色。

In Situ hybridization showed that OsUBP1 mRNA expressed in the tapetum, pollen grains, macrospore sac and the vascular bundle at the bottom of spikelets.

原位杂交分析表明，在花中OsUBP1 mRNA主要在药壁绒毡层、花粉粒、大孢子囊和颖花底部维管束中表达。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
