子囊孢子

The characteristics of ascospore, such as size, shape, symmetry, structure, pigmentation, presence, position and number of germ pores are the most important classified criteria of species.

对于种的划分，因子囊孢子的形态结构稳定，其大小、形状、萌发孔的数量及着生位置都比较恒定，应作为划分种的最重要的标准。

A cross was made between two isolates of Magnaporthe grisea, CH63 and TH16. A total of 78 ascospore isolates were tested for pathogenicity on 36 rice varieties. The 71 pathotypes were clearly observed in the sexual progeny.

报导了两个稻瘟菌株CH63和TH16的杂交后代在36个水稻品种上的致病性分离、遗传分析以及无毒基因组成的分析结果。78个子囊孢子菌株中呈现显著的致病性分离，共出现71种致病类型，在不同品种上分别出现1：1、1：3、3：1、1：7、1：15和15：1等的无毒性／毒性分离，表明供试菌株对不同品种的无毒性／毒性是一个或多个基因控制的。

Result The cell of the fungi was oval and monopole budding. The fungi had deposition and zone in liquid medium, its colony was red with smooth and gray surface, regular edge and sticky texture in solid medium, and the fungi had no ascospore and could not produce pseudohypha. The fungi was negative through glucose ferment and it could assimilate potassium nitrate.

结果］该菌细胞卵形，单极芽殖；在液体培养基中有沉淀且有菌环；在固体培养基中，菌落红色，表面平滑、暗淡，边缘整齐，质地粘稠；无子囊孢子；无假菌丝形成。

The ascospores, on the other hand, are produced by following sexual reproduction.

另一方面，子囊孢子是在有性生殖之后产生的。

An improvement on mass production of apothecia of Sclerotinia sclerotiorum, a causal agent of sclerotinia stem rot of oilseed rape, was achieved by screening suitalbe strains and evaluating factors affecting carpogenic germination for this fungus.

核盘菌引起包括油菜在内的多种经济作物的菌核病。为筛选抗菌核病的作物品种及探讨防治该病的其它途径，获得足够的子囊孢子是极其重要的技术环节。

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。

The release and survival of ascospores of a UK Sclerotinia sclerotiorum isolate were studied.

人们研究过一种源于英国菌核病的子囊孢子的生存和释放。

According to field observations and inoculation experiment,the diseasedplants bearing numerous perithecia left in the soil during harvest probably serveas the main source of infection.

小麦秆枯病菌子囊孢子必需要有小麦組織的刺激始能萌發。在缺乏刺激物时，萌發率一般在1%以下，加入刺激物后，萌發率可以提高数十倍。

小麦秆枯病菌子囊孢子必需要有小麦组织的刺激始能萌发。在缺乏刺激物时，萌发率一般在1%以下，加入刺激物后，萌发率可以提高数十倍。

C. fimbriata usually grows best at temperatures from 18 to 28 degrees C and is able to produce ascospores within a week.

C。 fimbriata通常温度在18到28度C生长最好，在1星期内能产生子囊孢子。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。

The factory affiliated to the Group primarily manufactures multiple-purpose pincers, baking kits, knives, scissors, kitchenware, gardening tools and beauty care kits as well as other hardware tools, the annual production value of which reaches US$ 30 million dollars.

集团所属工厂主要生产多用钳、烤具、刀具、剪刀、厨具、花园工具、美容套等五金产品，年生产总值3000万美元，产品价廉物美、选料上乘、质量保证，深受国内外客户的青睐
