子囊壳的

Most field isolates are self-fertile, producing many fruiting bodies called perithecia on the surface of the substrate or in culture.

大多数田间菌株是自交能孕的，在基质或培养物的表面上产生许多子实体称子囊壳。

Microspore Ye as the feather, small sporophyll sac formed by the polymerization, each polymer capsules formed by four small sporangia, small spores with dual airbags, and airbag Pinaceae pollen is similar to large sporophyll from the central axis and arranged in Brachypodium feather composition, Each Yibing has a shell bucket, each bucket containing shell upright ovules 10-12 months.

小孢子叶枝为羽状，小孢子叶由聚合囊组成，每个聚合囊由4个小孢子囊组成，小孢子具双气囊，与松科植物花粉的气囊相似，大孢子叶由中轴及羽状排列的短柄组成，每一柄上有一个壳斗，每个壳斗内有10—12个直立的胚珠。

The observation and comparison on morphology of the powdery mildew being collected on tree of heaven from Gansu, Beijing and Chengdu have been made. The result showed that the pathogen on leafs collected from three locations mentioned above was identified as Phyllactinia ailanthi.

对采自甘肃、北京和成都的臭椿白粉病标样进行了病原菌形态观察比较，结果显示，三个地区采集的标样为同一病原，均为子囊菌亚门、球针壳属真菌―臭椿球针壳。

Of 30,000 known Ascomycetes only 5,000 have been 'connected' to their anamorphs - results often 'messy' eg teleomorph genera, Nectria and Gibberella, both have anamorphs which have been classified in the anamorph genus Fusarium Many anamorphs (85%) have no known teleomorph - are termed Deuteromycetes.

有时将有性与无性联系容易，许多情况下难甚至做不到，因为有的菌丧失了有性生殖的能力。30 000种已知的子囊菌只有5 000种与无性态挂上了勾，结果往往是杂乱的，如有性阶段的丛剌壳属和赤霉属的无性阶段都是镰霉属。

By morphological and molecular methods the strain B3 was identified as Diaporthe and could exist under acidic condition, whose laccase had good thermostability.

通过形态学观察及测定其rDNA ITS序列对菌株B3进行鉴定，该菌株属于子囊菌亚门的腐皮壳属。

In order to understand the validity of the resistant genes to wheat powdery mildew in Shanxi province, in greenhouse condition, cleistothecia released ascospores were used to infect wheat seedling. The frequencies of virulence genes for 166 isolates of Erysiphe graminis f. sp. tritici from different ecological areas of Shanxi province were tested.

为明确小麦白粉病抗性基因在山西省的有效性，在温室条件下，通过闭囊壳释放子囊孢子侵染麦苗发病，利用28个已知抗病基因品种对分离自山西省不同生态区的166个小麦白粉病菌株进行了毒性基因频率测定。

And R8, stromata produced by the plant R3 and R8 in field;+= viable ascospores produced;= perithecia barren;—= no

上产生的子座；+=生成可育的子囊孢子；=生成子囊壳但败育；—=没有反应；空白=未做。

These fungi are subdivided into two families—nectriaceae and bionectriaceae—by the color reaction of perithecia in koh.

视子囊壳於koh溶液中的呈色反应，这类真菌可被分成两个科，nectriaceae与bionectriaceae。

At first, optimization for the perfect stage production of M. grisea was investigated in vitro. The number of perithecia and ascospores, the percentage of viable ascospores were markedly increased when juice of mature tomato was used, pH was adjusted around 5. 5 and 0.1％CaCO〓 was added in oatmeal tomato agar medium.

本研究首先选用自然成熟的番茄榨汁和燕麦片作为培养基的主要组分，通过调节培养基pH值在5.5左右并添加0.1％CaCO〓途径优化了稻瘟病菌有性世代形成的条件，显著增加了稻瘟病菌子囊壳形成的数量和子囊孢子的成活率。

Further, crosses among fertile isolates from the above four provinces were made.One of fourteen crosses produced perithcia,but none ascospores were generated.

用不同交配型的可育菌株进行互交，14个组合中只有1个组合产生子囊壳，但没有形成成熟的子囊孢子。

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。
